The primary objective of CU Aerospace's Phase II work will be to experimentally characterize the ElectriCOIL flow using advanced diagnostics and to demonstrate lasing of this electrically assisted chemical iodine laser. CU Aerospace (CUA) and theUniversity of Illinois at Urbana-Champaign (UIUC) believe that it is possible to construct a highly efficient electric generation scheme to provide the pr ...

The Phase I efforts aimed at establishing the feasibility of Air Film Damping for controlling vibration induced high-cycle fatigue (HCF) in gas turbine engine components. To establish this goal, current commercially available finite element software wasutilized to develop a methodology for predicting the effects of Air Film Damping on dynamic response of simple components such as beams and plates ...

High-performance HgCdTe infrared focal plane arrays (IRFPAs) sensing in the long-wavelength infrared (LWIR) region and advanced structures such as multi-color detectors required for future generation IRFPAs are highly desirable for various Air Forceapplications. Such device architectures require not only reliable extrinsic n- and p-type doping of HgCdTe but also the precise control of composition ...

As we look towards the next decade there are many opportunities to enhance services for navigation which compliment, enhance, and replace existing Aids to Navigation technologies. This Phase II project will continue the US Coast Guard¿s investigation of the development of a Virtual Aids to Navigation system by building a working prototype that delivers real-time data to the mariner. The vATON s ...

High performance infrared detectors with cutoff wavelength above 16 micrometers are highly needed for many applications such as early detection of long range missiles, pollution monitoring, and astronomy. Currently available detectors with high quantumefficiency and high uniformity in this wavelength range are extrinsic silicon detectors which have to be cooled below 10K. Here, we propose novel te ...

Scheduling is a complex, NP-hard problem that challenges the use of any single solution technique. In Phase I, we built a model that uses our multi-technique Quantum Leap Problem Solving Engine to solve a representative but simplified version of the AirForce Satellite Control Network (AFSCN) contact scheduling problem. The system demonstrated that it could schedule the hundreds (500 to 600) of t ...

Given two closely related pieces of software X and Y, where Y differs from X through a number of small but important (from a security point of view) modifications that were done to Y, the "diff" attack consists of comparing X and Y so as to pinpoint the fragments of code in which they differ. The differences between X and Y could include, among other things, the fact that Y contains credentials-c ...

Complex engineered systems such as the power systems of most military platforms involve a broad spectrum of technologies and interactive subsystems that must work synergistically. Due to the interdependencies between subsystems, it is becoming increasingly important to establish a simulation infrastructure that accurately accounts for the interactions between subsystems and promotes the collaborat ...

The need to protect airliners from terrorist manpad missiles has been underscored by recent events in which missiles were fired at commercial airliners as well as wide body aircraft flying into and out of Baghdad airport. The U.S. Government is looking at military aircraft protection systems in an attempt to extend this military technology to civilian airliners. This phase I SBIR researched a comp ...

During Phase I of the project, Sharma & Associates, Inc. developed a concept for a high speed freight truck intended for 70-ton, regular freight and bi-modal operation at speeds up to 150 mph. The truck uses a rigid frame and an independent, compliant, primary suspension for its basic architecture. Constant contact side-bearings and yaw dampers were also added to improve dynamic performance. Ve ...
