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 ...

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

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 ...

The rise of launch clouds to stabilization is forced by an altitude varying distribution of momention and buoyancy (temperature). In most of the plume, the temperature excess over that of the atmosphere is large and the buoyant force accelerates the launch products to "high" altitudes. The acceleration is retarded by the exhaust velocity, but augmented strongly by water vapor phase changes and pos ...

THERMAL AND COLD NEUTRON RADIOGRAPHY NON-DESTRICTIVE EVALUATION (NDE) SHOULD HAVE MANY ADVANTAGES OVER X-RAY RADIOGRAPHY IN AEROSPACE APPLICATIONS. UNFORTUNATELY, THE GENERATION OF THERMAL NEUTRONS RESULTS IN LOW BEAM FLUX AND DIFFUSE SOURCES RESULTING IN LONG EXPOSURE TIMES AND POOR RESOLUTION. PHYSICON PROPOSES THE USE OF A NOVEL OPTIC TO COLLIMATE AND CONCENTRATE NEUTRON BEAMS WHICH WILL LOWER ...
