Recent research has shown that effective jammer and clutter suppression is best performed with fully space-time adaptive processing. However, allowing adaptive weights on every tap on every element is computationally prohibitive and requires too many samples to converge. Eigenvalue analysis shows that the required number of degrees of freedom (DOF) is significantly less than the dimensionality of ...

We propose to develop ne%v methodolooy allowing non-technical planners to specify, generate, and solve multidimensional logistics network problems. Our approach is based on in- tegrating new generations of multidimensional spreadsheet software, mathematical programming languages, and ultimately interactive map-based user interfaces. Multidimensional logistics network problems include multicommodit ...

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 ...

Dynetics proposes to initiate a study to investigate the potential benefits of applying a lattice control surface technology to hypersonic vehicles as a means to improve aircraft performance and operating efficiency. Under the Phase I effert, Dynetics will develop preliminary designs of generic lattice control surface concepts suitable for use on various types of hypersonic vehicles. Dynetics will ...

This proposal is concerned with the accurate computer simulation of compressible transonic and supersonic flows. It explores the feasibility of developing a Computational Fluid Dynamics (CFD) code based on the p-version of the finite element method, which alleviates some of the inherent limitations and difficulties of established finite difference/finite volume methods for such flows. Numerical di ...

The proposed SBIR research targets the development of a state-of the-art- optical heat transfer sensor for unsteady measurement in modern turbomachinery. The operational principal of the sensor is based on the UV-induced fluoresence emission of rare-earth ion doped thermographic phosphors (TGP). With a multidimensional thermal imaging system, the sensor permits simultaneous characterization of pla ...
