The objective of the Phase II research is to utilize the lessons learned from the Phase I risk reduction work to develop a prototype CAD-programmable environment for the development of condition-based maintenance systems for rotorcraft. This developmentenvironment features a CAD scenario modeler for constructing, via click n' drag modeling, fault-to-failure damage models which can account for the ...

The feasibility of a new approach that will accelerate the modeling of problems involving rarefied gas dynamics is established. The proposed hybrid approach solves the Boltzmann equation directly using a carefully designed discrete-velocity model and adiscrete Monte Carlo collision process with several extensions that accelerates its computational capability in comparison with direct simulation M ...

JRM proposes a novel context-dependent, signature-based approach to improve the automation and quality of material-classification of imagery and arbitrary n-channel remote-sensed data. In the Phase I, JRM will design three key components: (1) anautomated N-channel signature-predictive material classification algorithm, (2) a pixel-material spatial-correlation refinement algorithm and (3) an iter ...

This Phase I project will develop and demonstrate an advanced process that utilizes a novel, high-intensity, low-frequency acoustic mixing technology in a system to rapidly produce a specialty fuel for use in chemical oxygen iodine lasers. The fuel is ahighly-reactive, mixed-base hydrogen peroxide (MHP). The MHP is used by a chemical oxygen iodine laser (COIL), which is the central element for th ...

The ACMS is a remote monitoring system that enables Battlefield intelligence gathering, situational awareness, and precision targeting without risk of personnel loss. Progeny provides a cost effective high performance approach to by designing flexiblesignal processing, sensors, deployment and communications links. Fundamental to ACMS is a forward area dispersed array of acoustic UGS's that are r ...

This proposed effort is to develop an approach to eliminate the requirement for hydraulics, swashplates and control rods on conventional helicopters. A servo tab on a servo tab approach is used to provide a two step amplification of power using the energyin the airstream to provide the cyclic, collective and high-frequency control for flight control and vibration reduction of a full size rotor us ...

Systems Planning and Analysis, Inc. (SPA) propose to systematically analyze, develop, and test a primary rotor control system based on trailing-edge flaps actuated by Magnetic Shape Memory Alloy (MSMA) materials. A comprehensive design effort will beundertaken based on the University of Maryland Advanced Rotor Code (UMARC) to determine full-scale flap actuation requirements (size, stroke, location ...

We propose to build and test an active-passive acoustic absorber for the Scorpius(TM) launch vehicle. The absorber is designed to couple into the first few acoustic modes of the payload fairing cavity. Mechanical designs are tuned to the lowest frequencymode and the higher-frequency modes are attenuated with feedback control. Suppression of the first few acoustic modes will reduce the sound pre ...

We will optimize the design of a monolithic, highly-integrated, active/passive, two-color infrared detector capable of S/MWIR avalanche photodetection, (S)MWIR passive photodetection, or LWIR passive photodetection. The structure is constructed usingback-to-back photodiodes (one designed for unity gain or avalanche operation) manufactured with well-established, band-engineered HgCdTe heterostructu ...
