1Treatment and outcomes of 1041 pediatric patients with neuroblastoma who received multidisciplinary care in China显示文摘Importance:Neuroblastoma is the most common extracranial malignant solid tumor in children.Multidisciplinary care is critical to improving the survival of pediatric patients with neuroblastoma.Objective:To systematically summarize the clinical characteristics of children with neuroblastoma and evaluate their prognosis with multidisciplinary care provided in a single center.Methods:This retrospective study analyzed the clinical data of 1041 patients with neuroblastoma who were diagnosed,treated,and followed-up in the Hematology-Oncology Center of Beijing Children’s Hospital from 2007 to 2019.Results:The median age at diagnosis was 34 months;80.8%of the patients were younger than 5 years of age.Notably,243 patients(23.3%)were classified as low-risk,249 patients(23.9%)were classified as intermediate-risk,and 549(52.7%)were classified as high-risk.Furthermore,956 patients underwent surgical resections;986(94.7%)patients received chemotherapy;and 176 patients with high-risk neuroblastoma received hematopoietic stem cell transplantation.The 5-year event-free survival(EFS)rate was 91.3%and 5-year overall survival(OS)rate was 97.5%in low-risk group;in the intermediate-risk group,these rates were 85.1%and 96.7%,respectively,while they were 37.7%and 48.9%in the high-risk group(P<0.001 for both).The 5-year EFS and OS rates were significantly higher in patients diagnosed between 2015 and 2019 than in patients diagnosed between 2007 and 2014(P<0.001).In total,278 patients(26.7%)exhibited tumor relapse or progression;the median interval until relapse or progression was 14 months.Of the 233 patients who died,83%died of relapse or progression of neuroblastoma and 4.3%died of therapy-related complications.Interpretation:The 5-year OS rate was low in high-risk patients,compared with low-and intermediate-risk patients.Multidisciplinary care is critical for improvement of survival in pediatric patients with neuroblastoma.Additional treatment strategies should be sought to improve the prognosis of patients with high-risk neuroblastoma.Yan Su Hong Qin Chenghao Chen Shengcai Wang Shihan Zhang Dawei Zhang Mei Jin Yun Peng Lejian He Xiaoman Wang Suyun Qian Maoquan Qin Ming Ge Fuquan Zhang Qi Zeng Huanmin Wang Xiaoli Ma Xin Ni 2020Pediatric Investigation2020,4,3:16
2Human umbilical cord-derived mesenchymal stem cell therapy in patients with COVID-19:a phase 1 clinical trial显示文摘No effective drug treatments are available for coronavirus disease 2019(COVID-19).Host-directed therapies targeting the underlying aberrant immune responses leading to pulmonary tissue damage,death,or long-term functional disability in survivors require clinical evaluation.We performed a parallel assigned controlled,non-randomized,phase 1 clinical trial to evaluate the safety of human umbilical cord-derived mesenchymal stem cells(UC-MSCs)infusions in the treatment of patients with moderate and severe COVID-19 pulmonary disease.The study enrolled 18 hospitalized patients with COVID-19(n=9 for each group).The treatment group received three cycles of intravenous infusion of UC-MSCs(3×107 cells per infusion)on days 0,3,and 6.Both groups received standard COVID-treatment regimens.Adverse events,duration of clinical symptoms,laboratory parameters,length of hospitalization,serial chest computed tomography(CT)images,the PaO2/FiO2 ratio,dynamics of cytokines,and IgG and IgM anti-SARS-CoV-2 antibodies were analyzed.No serious UC-MSCs infusion-associated adverse events were observed.Two patients receiving UC-MSCs developed transient facial flushing and fever,and one patient developed transient hypoxia at 12 h post UC-MSCs transfusion.Mechanical ventilation was required in one patient in the treatment group compared with four in the control group.All patients recovered and were discharged.Our data show that intravenous UC-MSCs infusion in patients with moderate and severe COVID-19 is safe and well tolerated.Phase 2/3 randomized,controlled,double-blinded trials with long-term follow-up are needed to evaluate the therapeutic use of UC-MSCs to reduce deaths and improve long-term treatment outcomes in patients with serious COVID-19.Fanping Meng Ruonan Xu Siyu Wang Zhe Xu Chao Zhang Yuanyuan Li Tao Yang Lei Shi Junliang Fu Tianjun Jiang Lei Huang Peng Zhao Xin Yuan Xing Fan Ji-Yuan Zhang Jinwen Song Dawei Zhang Yanmei Jiao Limin Liu Chunbao Zhou Markus Maeurer Alimuddin Zumla Ming Shi Fu-Sheng Wang 2020Signal Transduction and Targeted Therapy2020,5,1:16
3MiRNA-429 suppresses the growth of gastric cancer cells in vitro显示文摘Micro-RNAs(miRNAs) have been found to be implicated in a very wide range of physiological processes.This study was aimed to investigate the regulation of miRNA-429(miR-429) in gastric cancer cells on cell proliferation and apoptosis.Quantitative PCR was employed to detect the expressions of miR-429 after eukaryotic expression plasmid of miR-429 and its inhibitor were transiently transfected into poorly differentiated human gastric can-cer cell line BGC823.The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) reduction as-says were used to examine proliferation ability.Apoptosis was analyzed by flow cytometry after transfection.The results showed that 48 h after transfection,overexpression of miR-429 reached maximum efficiency.Compared with mock transfection,miR-429 inhibited tumor cell proliferation significantly(P < 0.05) at 48 h and 72 h.of Overexpression of miR-429 promoted tumor cell apoptosis when compared with mock transfected cells(P < 0.05).On the contrary,miR-429 inhibitor promoted tumor cell proliferation and inhibited apoptosis when compared with controls(P < 0.05).Our results suggested that miRNA-429 may serve as a tumor suppressor during tumorigenesis of gastric cancer and may be a potential gastric cancer therapeutic target.Di Liu Peng Xia Dongmei Diao Yao Cheng Hao Zhang Dawei Yuan Chen Huang Chengxue Dang 2012The Journal of Biomedical Research2012,26,5:12
4The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11

6Novel way to research nonlinear feedback shift register显示文摘In this paper,we regard the nonlinear feedback shift register(NLFSR)as a special Boolean network,and use semi-tensor product of matrices and matrix expression of logic to convert the dynamic equations of NLFSR into an equivalent algebraic equation.Based on them,we propose some novel and generalized techniques to study NLFSR.First,a general method is presented to solve an open problem of how to obtain the properties(the number of fixed points and the cycles with different lengths)of the state sequences produced by a given NLFSR,i.e.,the analysis of a given NLFSR.We then show how to construct all 22n-(l-n)/22n-lshortest n-stage feedback shift registers(nFSR)and at least 22n-(l-n)-1/22n-l-1shortest n-stage nonlinear feedback shift registers(nNLFSR)which can output a given nonperiodic/periodic sequence with length l.Besides,we propose two novel cycles joining algorithms for the construction of full-length nNLFSR.Finally,two algorithms are presented to construct 22n-2-1different full-length nNLFSRs,respectively.ZHAO DaWei PENG HaiPeng LI LiXiang HUI SiLi YANG YiXian 2014Science China(Information Sciences)2014,57,9:7
7Characterization and mapping of a novel mutant sms1 (senescence and male sterility 1) in rice显示文摘Plant senescence plays diverse important roles in development and environmental responses.However,the molecular basis of plant senescence is remained largely unknown.A rice spontaneous mutant with the character of early senescence and male sterility (sms) was found in the breeding line NT10-748.In order to identify the gene SMS1 and the underlying mechanism,we preliminarily analyzed physiological and biochemical phenotypes of the mutant.The mutant contained lower chlorophyll content compared with the wild type control and was severe male sterile with lower pollen viability.Genetic analysis showed that the mutant was controlled by a single recessive gene.By the map-based cloning approach,we fine-mapped SMS1 to a 67 kb region between the markers Z3-4 and Z1-1 on chromosome 8 using 1,074 F2 recessive plants derived from the cross between the mutant sms1 (japonica) × Zhenshan 97 (indica),where no known gene involved in senescence or male sterility has been identified.Therefore the SMS1 gene will be a novel gene that regulates the two developmental processes.The further cloning and functional analysis of the SMS1 gene is under way.Wenyi Yan Shenghai Ye Qingsheng Jin Longjun Zeng Yu Peng Dawei Yan Weibing Yang Donglei Yang Zuhua He Yanjun Dong Xiaoming Zhang 2010Journal of Genetics and Genomics2010,37,1:6
8Crystal structure of SARS-CoV-2 main protease in complex with protease inhibitor PF-07321332显示文摘Dear Editor,Since December 2019,the pandemic of coronavirus disease 2019(COVID-19)has taken a heavy toll on global health,creating an urgent need to develop effective strategies for prevention and treatment.The etiological agent,known as severe acute respiratory syndrome coronavirus 2(SARSCoV-2),has infected nearly 229.2 million people worldwide with more than 4.7 million deaths as of September 15,2021.Older age and preexisting health conditions are associated with worse clinical prognosis including higher mortality rates(Zhou et al.,2020).The global race to combat this pandemic has led to rapid deployment of numerous effective vaccines against SARS-CoV-2(Tregoning et al.,2021).However,the emergence of viral variants,including the Delta variant(B.1.617.2),compromised vaccine effectiveness with resurgence of SARS-CoV-2 infection among highly vaccinated population(Keehner et al.,2021).Therefore,development of therapeutics against the more conserved viral targets would be essential to contain the spread of COVID-19 and reduce mortality.Yao Zhao Chao Fang Qi Zhang Ruxue Zhang Xiangbo Zhao Yinkai Duan Haofeng Wang Yan Zhu Lu Feng Jinyi Zhao Maolin Shao Xiuna Yang Leike Zhang Chao Peng Kailin Yang Dawei Ma Zihe Rao Haitao Yang 2022Protein & Cell2022,13,9:6
9Design of Drilling and Riveting Multi-functional End Effector for CFRP and Aluminum Components in Robotic Aircraft Assembly显示文摘To fulfill the demands for higher quality,efficiency and flexibility in aviation industry,a multi-functional end effector is designed to automate the drilling and riveting processes in assembling carbon fiber reinforced polymer(CFRP)and aluminum components for a robotic aircraft assembly system.To meet the specific functional requirements for blind rivet installation on CFRP and aluminum materials,additional modules are incorporated on the end effector aside of the basic processing modules for drilling.And all of these processing modules allow for a onestep-drilling-countersinking process,hole inspection,automatic rivet feed,rivet geometry check,sealant application,rivet insertion and installation.Besides,to guarantee the better quality of the hole drilled and joints riveted,several online detection and adjustment measures are applied to this end effector,including the reference detection and perpendicular calibration,which could effectively ensure the positioning precision and perpendicular accuracy as demanded.Finally,the test result shows that this end effector is capable of producing each hole to a positioning precision within ±0.5 mm,aperpendicular accuracy within 0.3°,a diameter tolerance of H8,and a countersink depth tolerance of±0.01 mm.Moreover,it could drill and rivet up to three joints per minute,with acceptable shearing and tensile strength.Zhang Lin Tian Wei Li Dawei Hong Peng Li Zhenyu Zhou Weixue Liao Wenhe 2018Transactions of Nanjing University of Aeronautics and Astronautics2018,35,3:5
10Bionic Quadruped Robot Dynamic Gait Control Strategy Based on Twenty Degrees of Freedom显示文摘Quadruped robot dynamic gaits have much more advantages than static gaits on speed and efficiency, however high speed and efficiency calls for more complex mechanical structure and complicated control algorithm. It becomes even more challenging when the robot has more degrees of freedom.As a result, most of the present researches focused on simple robot, while the researches on dynamic gaits for complex robot with more degrees of freedom are relatively limited. The paper is focusing on the dynamic gaits control for complex robot with twenty degrees of freedom for the first time. Firstly, we build a relatively complete 3 D model for quadruped robot based on spring loaded inverted pendulum(SLIP) model, analyze the inverse kinematics of the model, plan the trajectory of the swing foot and analyze the hydraulic drive. Secondly, we promote the control algorithm of one-legged to the quadruped robot based on the virtual leg and plan the state variables of pace gait and bound gait. Lastly, we realize the above two kinds of dynamic gaits in ADAMS-MATLAB joint simulation platform which testify the validity of above method.Dawei Gong Peng Wang Shuangyu Zhao Li Du Yu Duan 2018IEEE/CAA Journal of Automatica Sinica2018,5,1:3
11On the Two Successive Supercold Waves Straddling the End of 2020 and the Beginning of 2021显示文摘Two supercold waves straddling 2020 and 2021 successively hit China and caused record-breaking extremely low temperatures.In this study,the distinct features of these two supercold waves are analyzed on the medium-range time scale.The blocking pattern from the Kara Sea to Lake Baikal characterized the first cold wave,while the large-scale tilted ridge and trough over the Asian continent featured the second cold wave.Prior to the cold waves,both the northwest and hyperpolar paths of cold air contributed to a zonally extensive cold air accumulation in the key region of Siberia.This might be the primary reason why strong and extensive supercold waves occur even under the Arctic amplification background.The two cold waves straddling 2020 and 2021 exhibited distinct features:(1)the blocking circulation occurred to the north or the east of the Ural Mountains and was not confined only to the Ural Mountains as it was for the earlier cold waves;(2)the collocation of the Asian blocking pattern and the polar vortex deflection towards East Asia preferred the hyperpolar path of cold air accumulation and the subsequent southward outburst;and(3)both high-and low-frequency processes worked in concert,leading to the very intense cold waves.The cold air advance along the northwest path,which coincides with the southeastward intrusion of the Siberian High(SH)front edge,is associated with the high-frequency process,while the cold air movement along the hyperpolar path,which is close to the eastern edge of the SH,is controlled by the low-frequency process.Cholaw BUEH Jingbei PENG Dawei LIN Bomin CHEN 2022Advances in Atmospheric Sciences2022,39,4:3
12Ameliorating the interfacial issues of all-solid-state lithium metal batteries by constructing polymer/inorganic composite electrolyte显示文摘Lithium metal is one of the most promising anodes for next-generation batteries due to its high capacity and low reduction potential.However,the notorious Li dendrites can cause the short life span and safety issues,hindering the extensive application of lithium batteries.Herein,Li_(7)La_(3)Zr_(2)O_(12)(LLZO)ceramics are integrated into polyethylene oxide(PEO)to construct a facile polymer/inorganic composite solid-state electrolyte(CSSE)to inhibit the growth of Li dendrites and widen the electrochemical stability window.Given the feasibility of our strategy,the designed PEO-LLZO-LiTFSI composite solid-state electrolyte(PLLCSSE)exhibits an outstanding cycling property of 134.2 mAh g^(-1) after 500 cycles and the Coulombic efficiency of 99.1%after 1000 cycles at 1 C in LiFePO_(4)-Li cell.When cooperated with LiNi_(0.6)Co_(0.2)Mn_(0.2)O_(2)(NCM622)cathode,the PLL-CSSE renders a capacity retention of 82.4%after 200 cycles at 0.2 C.More importantly,the uniform dispersion of LLZO in PEO matrix is tentative tested via Raman and FT-IR spectra and should be responsible for the improved electrochemical performance.The same conclusion can be drawn from the interface investigation after cycling.This work presents an intriguing solid-state electrolyte with high electrochemical performance,which will boost the development of all-solid-state lithium batteries with high energy density.Su Wang Qifang Sun Wenxiu Peng Yue Ma Ying Zhou Dawei Song Hongzhou Zhang Xixi Shi Chunliang Li Lianqi Zhang 2021Journal of Energy Chemistry2021,30,7:2
13Effect of cross-flow direction of coolant on film cooling effectiveness with one inlet and double outlet hole injection显示文摘In order to study the effect of cross-flow directions of an internal coolant on film cooling performance,the discharge coefficients and film cooling effectiveness with one inlet and double outlet hole injections were simulated.The numerical results show that two different cross-flow directions of the coolant cause the same decrease in the discharge coefficients as that in the case of supplying coolant by a plenum.The different proportion of the mass flow out of the two outlets of the film hole results in different values of the film cooling effectiveness for three different cases of coolant supplies.The film cooling effectiveness is the highest for the case of supplying coolant by the plenum.At a lower blowing ratio of 1.0,the film cooling effectiveness with coolant injection from the right entrance of the passage is higher than that from the left entrance of the passage.At a higher blowing ratio of 2.0,the opposite result is found.Guangchao Lin Chaolin Wu Wei Zhang Zhihai Kou Dawei Peng 2012Propulsion and Power Research2012,1,1:2

15Mechanism,condition and characteristics for the formation of the network structure in Zr-Al-Ni-Cu bulk metallic glasses显示文摘Mechanism,condition and characteristics for the formation of the network structure in a group of Zr-Al-Ni-Cu bulk metallic glasses(BMGs) were investigated.The results show that the constituent segregation and/or the symplastic growth would be the mechanisms for the formation of the cell structure in the present Zr-Al-Ni-Cu BMGs.The cell structure can be easily obtained for the glass forming alloys whose compositions locate nearby the eutectic point.The shorter the distance is from the eutectic point,the larger the cell and the thicker the cell wall of the network structure will be.The present investigation would provide useful information for the development of the BMG with the network structure.AN WeiKe DING DaWei CAI AnHui ZHOU GuoJun LUO Yun LI JiangHong PENG YongYi 2015Science China(Physics,Mechanics & Astronomy)2015,58,6:2
16Charge density wave and weak Kondo effect in a Dirac semimetal CeSbTe显示文摘Using angle-resolved photoemission spectroscopy(ARPES) and low-energy electron diffraction(LEED), together with densityfunctional theory(DFT) calculation, we report the formation of charge density wave(CDW) and its interplay with the Kondo effect and topological states in CeSbTe. The observed Fermi surface(FS) exhibits parallel segments that can be well connected by the observed CDWordering vector, indicating that the CDWorder is driven by the electron-phonon coupling(EPC) as a result of the nested FS. The CDW gap is large(~0.3 eV) and momentum-dependent, which naturally explains the robust CDWorder up to high temperatures. The gap opening leads to a reduced density of states(DOS) near the Fermi level(EF), which correspondingly suppresses the many-body Kondo effect, leading to very localized 4 f electrons at 20 K and above. The topological Dirac cone at the X point is found to remain gapless inside the CDW phase. Our results provide evidence for the competition between CDWand the Kondo effect in a Kondo lattice system. The robust CDWorder in CeSbTe and related compounds provide an opportunity to search for the long-sought-after axionic insulator.Peng Li BaiJiang Lv Yuan Fang Wei Guo ZhongZheng Wu Yi Wu DaWei Shen YueFeng Nie Luca Petaccia Chao Cao Zhu-An Xu Yang Liu 2021Science China(Physics,Mechanics & Astronomy)2021,64,3:1

18An Experimental Study on Homoharringtonine Liposome and Glaucoma Filtration Surgery显示文摘Purpose: To observe the inhibitory action of homoharringtonine liposome during the healing process of wounds in the filtering sitesMethods: posterior sclerectomies were performed in 14 rabbits. Postoperatively one eye of each rabbit received subconjunctival injections of HH liposome and fellow eye received saline injection in a randomized masked fashion.Results; Fourteen days after operation the IOP of experimental eyes reduced significantly (P < 0.01) as compared with the controlled eyes, and the number of remaining filtering blebs increased noticeably (P< 0.05). Pathohistological examination revealed that the number of fibroblasts per square micron in the filtering sites and the thickness of the scars in the center of the filtering sites of the experimental eyes were less than those of the controlled eyes. No serious ocular toxic and side effects were found.Conclusion : This experiment suggests that homoharringtonine liposome can markedly inhibit the scar formation of filtering sites after glaucomaDawei Peng, Kerning Yu, Shujun Zeng, Yongping Li Jianxian Lin, Yuping Wu, Wenbing ZhouZhongshan Ophthalmic Center , Sun Yat-sen University of Medical Sciences , Guangzhou 510060 , China Department of Pharmacology, Sun Yat-sen University of Medical Sciences , Guangzhou 510089, China 1999眼科学报1999,15,1:1

20Refined Aerodynamic Test of Wide-Bodied Aircraft and Its Application显示文摘The large dual-channel wide-bodied aircraft has a long range and a high cruise Mach number.Therefore,its aerodynamic design requires a high level ofwind tunnel test refinement.Based on the requirements of aerodynamic design for the future wide-bodied aircraft and the characteristics of high-speed wind tunnel tests,the error theory is introduced to analyze the factors affecting the accuracy of the test data.This study carries out a series of research on the improvement of refined aerodynamic test technology in an FL-26 wind tunnel,including design and optimization of the support system of wide-bodied aircraft,model attitude angle measurement,Mach number control accuracy,measurement and control system stability,test data correction and perfection,high-precision force balance and standard model development.In addition,the effect of the standard specification of the refined aerodynamic test is investigated to improve the data quality.The research findings have been applied in the standard model test and subsequent models of wide-bodied aircraft.The results show that whenMach numbers are less than 0.9,the control accuracy of Mach numbers in the FL-26 wind tunnel is smaller than 0.001 and the measurement error of attack angle is smaller than 0.01°.Therefore,it has the ability to correct the data influenced by factors,such as support/wall interference,model deformation,floating resistance and airflow deflection angle.The repeatability accuracy of the standard model’s comparison test shows that the lift coefficient is less than or equal to 0.0012,the drag coefficient is less than or equal to 0.00004,pitching moment coefficient is less than or equal to 0.0004.The bending resolution of the model’s deformation measurement is less than 0.2 mm,and the tensional deformation is smaller than 0.04°.The revised aerodynamic data and model deformation measurement results have good agreement with that of the ETW wind tunnel.The results demonstrate that the improved technology presented in this paper can significantly enhance the refined aerodynamic test of wide-bodied aircraft.Dawei Liu Zhiwei Jin Xin Peng Gang Liu Yue Zhang 2023Computer Modeling in Engineering & Sciences2023,,9:1
