A PROJECT IS PROPOSED WHERE EXISTING MODELS ARE USED TO PREDICT THE EFFECT OF MULTIPLE BURST AIRSLAP ON HARDENED SILOS. A SMALL NUMER OF THREAT/TARGET CONFIGURATIONS WILL BE SELECTED AS REPRESENTATIVE OF THOSE OF GREATEST INTEREST OR AS BOUNDING THE AIRSLAP PROBLEM. THE MODELS WILL BE EVALUATED AND MATCHED TO THE THREAT/TARGET CASES FOR OPTIMUM PERFORMANCE. THE PREDICTIONS WILL BE TABULATED AS A R ...

Fires in dry bays of military aircraft present a significant hazard that must be addressed with advanced fire suppression systems. The USAF is interested in concepts that do not require power or active sensing of fire for proper operation. ADA Technologies, Inc. has been developing fine water mist fire suppression technology for the past 10 years, and proposes a solution for this problem that inco ...

THIS PHASE I PROPOSAL CONCERNS AN EVALUATION OF THE POTENTIAL OF THE ALTI-OXY PROCESS TO PRODUCE TI-LI-AL ALLOYS IN POWDER FORM. THE FOLLOW ON PHASE II PROGRAM WOULD INVOLVE PRODUCTION OF SUFFICIENT MATERIAL TO PRODUCE PARTS FOR TESTING.

There is a need to monitor the structural health of aerospace components operating in extreme temperatures ranges (e.g. -60 to +300C) and with high accelerations. Ideally the sensors employed for this task should be passive (i.e. not powered through batteries), permanently placed on the critical components and transmit the relevant data to a remote data processing center wirelessly.  Albido is pr ...

Polymers in space are subjected to various threats including hyperthermal oxygen atoms, UV and VUV photons, and ions.  These threats can degrade the polymer and lead to static charge accumulation.  This Phase II proposal will build on the Phase I work which demonstrated that inorganic films grown by atomic layer deposition (ALD) can protect polymers such as Kapton, Teflon and PMMA.  Al2O3 ALD f ...

THE DISCRETE ELEMENT METHOD WILL BE APPLIED TO SIMULATE THE DYNAMIC RESPONSE OF SOIL BY MODELING THE SOIL AS A DISCRETE GRANULAR MATERIAL. THE INTERACTION AND MOTION OF EACH SOIL GRAIN WILL BE MODELED EXPLICITY. THE PROGRAM AUTOMATICALLY TRACKS THE MOTION OF EACH GRAIN. A PARAMETRIC STUDY WILL BE UNDERTAKEN TO DETERMINE THE DEPENDENCE OF MACROSCOPIC SOIL BEHAVIOR ON MICROSCOPIC PROPERTIES. AN EQUI ...

A SELF-CONTAINED, ULTRASONIC ULLAGE SPACE COMPOSITION DETECTOR BASED ON THE SPEED OF SOUND OF THE CONTAINED ATMOSPHERE IS A FEASIBLE METHOD OF MEASURING THE CHANGE IN THE RATIO OF AIR TO JET FUEL VAPOR. THIS DETECTOR WOULD BE USED TO MONITOR THE COMPOSITION OF THE ATMOSPHERE CONTAINED IN THE ULLAGE SPACE OF FUEL TANK SPECIMENS. FOR EVERY MIXTURE OF AIR AND JET FUEL, A SPECIFIC SPEED OF SOUND WILL ...

Aqwest proposes to develop an advanced thermal management for cooling of electronic components using a variable conductance heat sink (VCHS) offering unparalleled capabilities in high-heat flux handling and temperature control. The project will produce a cooling system with the following benefits to wide band gap amplifiers and high-power laser diodes (HPLD): 1) Heat flux handling > 1200 W/cm2 2) ...
