1Formulation development and characterization of cellulose acetate nitrate based propellants for improved insensitive munitions properties显示文摘Cellulose acetate nitrate(CAN) was used as an insensitive energetic binder to improve the insensitive munitions(IM) properties of gun propellants to replace the M1 propellant used in 105 mm artillery charges.CAN contains the energetic nitro groups found in nitrocellulose(NC),but also acetyl functionalities,which lowered the polymer's sensitivity to heat and shock,and therefore improved its IM properties relative to NC.The formulation,development and small-scale characterization testing of several CAN-based propellants were done.The formulations,using insensitive energetic solid fillers and high-nitrogen modifiers in place of nitramine were completed.The small scale characterization testing,such as closed bomb testing,small scale sensitivity,thermal stability,and chemical compatibility were done.The mechanical response of the propellants under high-rate uni-axial compression at,hot,cold,and ambient temperatures were also completed.Critical diameter testing,hot fragment conductive ignition(HFCI) tests were done to evaluate the propellants' responses to thermal and shock stimuli.Utilizing the propellant chemical composition,theoretical predictions of erosivity were completed.All the small scale test results were utilized to down-select the promising CAN based formulations for large scale demonstration testing such as the ballistic performance and fragment impact testing in the105 mm M67 artillery charge configurations.The test results completed in the small and large scale testing are discussed.Thelma MANNING Jeffrey WYCKOFF Carlton ADAM Eugene ROZUMOV Kenneth KLINGAMAN Viral PANCHAL Joseph LAQUIDARA Mike FAIR John BOLOGNINI Keith LUHMANN Steve VELARDE Christine KNOTT Stephanie M.PIRAINO Kevin BOYD 2014Defence Technology(防务技术)2014,10,2:2
2Enhanced propellant performance via environmentally friendly curable surface coating显示文摘Surface coating of granular propellants is widely used in a multiplicity of propellants for small, medium and large caliber ammunition. All small caliber ball propellants exhibit burning progressivity due to application of effective deterrent coatings. Large perforated propellant grains have also begun utilizing plasticizing and impregnated deterrent coatings with the purpose of increasing charge weights for greater energy and velocity for the projectile. The deterrent coating and impregnation process utilizes volatile organic compounds(VOCs) and hazardous air pollutants(HAPs) which results in propellants that need to be forced air dried which impacts air quality. Propellants undergo temperature fluctuations during their life. Diffusion coefficients vary exponentially with variations in temperature. A small temperature increase can induce a faster migration, even over a short period of time, which can lead to large deviations in the concentration. This large concentration change in the ammunition becomes a safety or performance liability. The presence of both polymeric deterrents and nitroglycerin(NG) in the nitrocellulose matrix and organic solvents leads to higher diffusion rates. This results in continued emissions of VOCs and HAPs. Conventional polymers tend to partition within the propellant matrix. In other words,localized mixing can occur between the polymer and underlying propellant. This is due to solvent induced softening of the polymer vehicle over the propellant grain. In effect this creates a path where migration can occur. Since nitrate esters, like NG, are relatively small, it can exude to the surface and create a highly unstable and dangerous situation for the warfighter. Curable polymers do not suffer from this partitioning due to 'melting' because no VOC solvents are present. They remain surface coated. The small scale characterization testing, such as closed bomb testing, small scale sensitivity, thermal stability,and chemical compatibility, will be presented. The 30 mm gun demonstration firing data at hot, cold, and ambient temperatures will also be presented.Thelma Manning Jeffrey Wyckoff Kenneth Klingaman Viral Panchal Eugene Rozumov John Bolognini Ming Wang Young Subhash Patel 2017Defence Technology(防务技术)2017,13,3:2

15Innovative boron nitride-doped propellants显示文摘The U.S. military has a need for more powerful propellants with balanced/stoichiometric amounts of fuel and oxidants. However, balanced and more powerful propellants lead to accelerated gun barrel erosion and markedly shortened useful barrel life. Boron nitride(BN) is an interesting potential additive for propellants that could reduce gun wear effects in advanced propellants(US patent pending 2015-026P). Hexagonal boron nitride is a good lubricant that can provide wear resistance and lower flame temperatures for gun barrels. Further, boron can dope steel, which drastically improves its strength and wear resistance, and can block the formation of softer carbides. A scalable synthesis method for producing boron nitride nano-particles that can be readily dispersed into propellants has been developed. Even dispersion of the nano-particles in a double-base propellant has been demonstrated using a solvent-based processing approach. Stability of a composite propellant with the BN additive was verified. In this paper, results from propellant testing of boron nitride nano-composite propellants are presented, including closed bomb and wear and erosion testing. Detailed characterization of the erosion tester substrates before and after firing was obtained by electron microscopy,inductively coupled plasma and x-ray photoelectron spectroscopy. This promising boron nitride additive shows the ability to improve gun wear and erosion resistance without any destabilizing effects to the propellant. Potential applications could include less erosive propellants in propellant ammunition for large, medium and small diameter fire arms.Thelma MANNING Richard FIELD Kenneth KLINGAMAN Michael FAIR John BOLOGNINI Robin CROWNOVER Carlton P.ADAM Viral PANCHAL Eugene ROZUMOV Henry GRAU Paul MATTER Michael BEACHY Christopher HOLT Samuel SOPOK 2016Defence Technology(防务技术)2016,12,2:1

19Adalimumab efficacy in enteropathic spondyloarthritis: A 12-mo observational multidisciplinary study显示文摘AIM To report adalimumab(Ada) efficacy on articulargastrointestinal disease and health-related quality of life(HRQo L) in patients with enteropathic spondyloarthritis(ES).METHODS A cohort of 52 patients with ES was evaluated in the departments of gastroenterology and internal medicine. At baseline, all patients underwent assessment by an integrated gastro-rheumatologic evaluation of articular and gastrointestinal activity, as well patient reported outcomes(PROs) of the HRQo L questionnaires. After this integrated evaluation and following a specific working flowchart, the Ada anti-tumor necrosis factor(TNF)-inhibitor was assigned to a cohort of 30 patients and its clinical efficacy was evaluated at baseline and after 6-mo and 12-mo treatment by the following tests:(1) Ankylosing Spondylitis Disease Activity ScoreC-Reactive Protein(ASDAS-CRP); Bath Ankylosing Spondylitis Disease Activity Index(BASDAI), Bath Ankylosing Spondylitis Functional Index(BASFI) and Bath Ankylosing Spondylitis Metrology Index(BASMI) for articular activity;(2) Inflammatory Bowel Disease Questionnaire(IBDQ), Crohn's Disease Activity Index(CDAI) and partial Mayo(p Mayo) score for gastrointestinal symptoms and activity; and(3) Health Assessment Questionnaire(HAQ), Patient Global Assessment(PGA) and Short Form-36 health survey(SF-36) questionnaires for PROs of the HRQo L.RESULTS Integrated evaluation and management of the patients affected by ES, carried out simultaneously by a gastroenterologist and a rheumatologist, allowed clinicians to choose the optimal therapeutic strategy. In a cohort of 30 ES patients affected by active articular and gastrointestinal disease, or axial active articular inflammation, Ada led to fast and sustained improvement of both articular and gastrointestinal disease activities. In fact, all the clinimetric evaluation tests exploring articular or gastrointestinal activity, as well as all the HRQo L scores, showed a significant improvement having been achieved at the earliest(6-mo) assessment. This important clinical improvement was maintained at the 12-mo follow-up. Importantly, global and gastrointestinal quality of life significantly correlated with articular disease activity, providing evidence to support that the integrated evaluation is the best option to manage patients with ES.CONCLUSION Ada treatment, upon multidisciplinary(gastrorheumatologic) evaluation, significantly improves both articular and gastrointestinal inflammation, thereby improving the HRQo L in patients affected by ES.Michele Maria Luchetti Devis Benfaremo Francesco Ciccia Laura Bolognini Monia Ciferri Alessia Farinelli Matteo Rossini Piergiorgio Mosca Giovanni Triolo Armando Gabrielli 2017World Journal of Gastroenterology2017,23,39:1
