Award Data

Most spacecraft require a memory to store data prior to the transmission of the data to an earth station. Until recently, the majority of spacecraft data storage requirements were provided by tape recorders. In 1989, however, a new era in spacecraft data storage began when SEAKR Engineering developed the first production Solid State Recorder (SSR). The on-orbit success of this and subsequent SE ...

Intelligent materials open new avenues to improve performance, reliability and longevity of future aerospace vehicle structures by allowing the structural materials themselves to become active elements for multiple system functions. However, the application of intelligent materials and structures has been inhibited because the effects of microstructural interactions between intelligent and host ma ...

The xpatch code suite, today combines a highly regarded high-frequency RCS prediction code with several visualization tools and a host of CAD editing and conversion programs. Currently, ideal conditions are always assumed by xpatch. In reality, sensor characteristics and atmospheric effects play a part in the appearance of a collected signature. In this proposal, we outline a course fo ...

This proposed Phase I project addresses the Air Force requirement for a system analysis of rotors supported with magnetic bearings by combining a powerful, user oriented multi-shaft rotor dynamics program with state-of-the-art models of a magnetic bearing and control system, gas (foil) bearings, and auxiliary rolling element bearings. This is the only approach that will provide a comple ...

This project investigates a novel fiber reinforcement concept for propellant bonding that replaced most or all of the adhesive liner with a high surface area carbon fiber substrate. The fiber diameter, length, packing fraction and surface treatment are adjusted for maximum bond effectiveness corresponding to a given grain distribution and binder composition. Proposed electrostatic fiber placement ...

Thermal storage devices based on phase-change materials (PCMs) have traditionally been box-like structures with robust walls and PCM volume fractions

The extreme environment of a rocket nozzle has high velocity hot combustion products that will erode an uncooled throat area. When the nozzle temperature is high, physical and chemical processes will erode even the most refractory materials such as tungsten, carbon and carbide ceramics. Modern hybrid rockets pose especially challenging problems because of higher combustion temperatures and poten ...

Modeling real-world entities using software objects allows the development of functional objects that have self-knowledge and are reusable. These objects are sometime called software components, and can be used in a manner analogous to the integrated circuits in computer hardware. Information and knowledge stored in databases today consists of pure data possessing no inherent functionality or kn ...
