THE PRIMARY OBJECTIVE OF THIS PROJECT IS TO PROVIDE THE DESIGNER OF AN TI-RADIATION HOMING MISSILES WITH THE INFORMATION NECESSARY TO STRUCTURE FUTURE STUDIES AND TECHNOLOGY PROGRAMS AIMED AT DEVELOPING AN ANTI- RADIATION MISSILE CAPABLE OF HOMING ON THREAT RADIATION MISSILE CAPABLE OF HOMING THREAT RADARS UTILIZING SPREAD SPECTRUM TECHNIQUES. THIS INVOLVES THE FOLLOWING TWO TASKS: 1. DEFINE THE C ...

THIS RESEARCH ADDRESSES TECHNIQUES AND MATERIALS FOR ON-ORBIT MAINTENANCE AND REFURBISHMENT OF THERMAL CONTROL SURFACE COATINGS USED ON LONG-LIFE SPACECRAFT. IN MANY CASES, CONSERVATIVE ASSUMPTIONS ON THE EFFECTS OF LONG-TERM DEGRADATION HAVE DRIVEN THE DESIGN OF SPACECRAFT THERMAL SYSTEMS TOWARD OVER CAPACITY WHICH RESULTS IN WEIGHT, SIZE, COMPLEXITY, AND COST PENALTIES. IF CRITICAL SURFACES COUL ...

The primary objective of this proposed work is to develop a method of producing integrally stiffened, complex shaped monolithic structural components in high strength aluminum alloys at a lower cost and lighter weight than equivalent conventional built-up assemblies. In Phase I the feasibility of attaining this objective will be demonstrated by conducting a series of subscale experiments based upo ...

N/A

Development of combined Air-Turbo-Rocket(ATC/Scramjet component technology suitable for numerous USAF propulsion missions is proposed. Preliminary component design will focus on attaining fully throttleable boost and sustain thrust, vehicle speeds from Mach 0 to 8, and range as required. Activities during Phase I include: (1) Generator of an ATR/Scramjet system and component analysis methodology b ...

The current development of an electric power generation system for the More Electric Aircraft (MEA) is based on a low-risk extension of existing three-phase, switched reluctance machine (SRM) technology. This research program proposes to study an alternate two-phase SRM and its associated power-conditioning converter. By the nature of the proposed machine, it has 50% of its stator coils active at ...

The ability of subjects to localize and identify each member of a set of acoustic signals will be measured. The acoustic signals will be presented in random order at several locations in auditory space, also chosen randomly. The acoustic signals are constructed to maximize the cues they present for localization and identification in that they contain a wide range of frequencies and timing informat ...
