Accurate Automation Corporation proposes a three-pronged effort to build on the Phase I program to develop technologies in support of the NASA Hyper-X program and the X-43 series of research vehicles (X-43A, X-43B, and X-43C). The data and technologies developed under the proposed Phase II program will also support the development and testing of future hypersonic vehicles and reusable launch vehic ...

The widespread use of communication devices and radar systems has made our society increasingly vulnerable to disruptive, high-power, short pulse electromagnetic interference (EMI) and high power microwaves (HPM). Significant advances in devices thatproduce these high-power, short pulses have been made in the US and abroad in the past few decades. As a result, the need for devices that can prote ...

NASA is interested in the development of highly advanced systems, subsystems and components to enable future robotic and manned missions. A key requirement for these challenging missions will be the development of high efficiency power conversion systems with increased power density. Ecotera Energy proposes an innovative gas turbine improvement, the Thermochemical Energy Conversion (TEC) engine, w ...

Develop a titanium, welded metal bellows extendable sunshade to deploy over seeker system optics in kinetic kill vehicles and other military missile systems that employ optical tracking. One object of the sunshade is to offer an alternative technology tohelp improve the durability of optical coatings by minimizing thermal gradients on the coatings as would be generated by free airflow across the ...

Thermal decomposition of hydrogen peroxide may provide significant weight, operability, envelope, and cost benefits over traditional catalytic decomposition units used in propulsion and energy systems. However, no proven methods exist for the design ofreliable and efficient thermal decomposition devices. A validated engineering design model and definition of safe operating regimes are pressing n ...

This project identifies a new approach to silicon x-ray detector technology wherein: (i) the detector geometry is changed to provide a much lower capacitance for a given active area and volume, (ii) the conventional Si(Li) detector is replaced with a stable, oxide-passivated, low leakage-current, deep sensitive-depth, v-type Si element, and (iii) the conventional FET in the preamplifier is replace ...

Despite numerous recent developments in the area of thermal management, there is now a critical shortage of cooling schemes that can handle anticipated heat loads in many military and commercial applications. The lack of effective cooling schemes hasemerged as an obstacle to electronic packaging at the device, module, and system levels. This study incorporates liquid cooling techniques and capit ...

Multifunctional structure encompasses a revolutionary level of integration that improves performance and reduces cost. Subsystem functionality is integrated into structural members to eliminate the need for subsystem interconnecting wires, cables, lines,and supporting brackets. Avionics support racks can be eliminated. Large modular structure with embedded subsystem functionality will eliminate ...

An innovative solution is presented for production of precise through-hole arrays (holes 0.1 to 0.5 mm diameter and 0.5 to 5 mm deep) in hardened metals. Precise hole-arrays are required for a number of military applications. The feasibility of amultiple parallel electrode Electro-Discharge Machining (EDM) process has been demonstrated. The proposed effort outlines further development to refine ...

MDA has a need for various types of compact, lightweight motorized actuators for use in divert and attitude control systems (DACS) on ballistic missiles. DSM proposes the development of a high specific power (HSP) piezoelectric actuator to command thevalves in such DACS. The proposed actuator makes use of a friction amplification concept to provide extremely high clamping and driving forces. Th ...
