Recent advancements in open rotor engine concepts warrant continued research, however the cost of wind tunnel tests is not insignificant. Because the jet noise of an open rotor engine, or even that of a geared fan, is very low in relation to the fan noise, it is evident that fan noise reduction technology is now just as important as jet noise reduction. A low cost test system is needed that woul ...

In this SBIR Phase I program, we propose to fabricate high-efficiency and radiation hard solar cells based on InGaN material system that can cover the whole solar spectrum by adjusting the alloy composition. The main program objectives include the fabrication of InGaN-based solar cells on large diameter substrates, with external efficiency in excess of 35%, and capable of long life operation in h ...

This SBIR proposal addresses the liquid phase epitaxy (LPE) of gallium nitride (GaN) films using nitrogen-enriched metal solutions. Growth of GaN from solutions offers the possibility of drastically reducing the density of line defects. As these defects adversely affect both breakdown voltages and electron velocities, their reduction can significantly increase the performance of high power Ka-ban ...

NASA operates manned spacecraft according to rigorously-defined standard operating procedures. Unfortunately, operating procedures are often written in different languages. For example, Orion will use automatic procedures written in SCL, the Spacecraft Command Language, while backup manual procedures may be developed in PRL, the Procedure Representation Language. However, procedures developed in ...

During this phase I SBIR effort unique proven lattice and bandgap engineering techniques will be utilized to epitaxially grow InAlAs / InGaAs on GaN substrate for the design and fabrication of high power reconfigurable transceiver single MMIC.

TLC demonstrated a high performance remote Doppler Radar adjustable X-band to W-band transceiver chip that can perform well as a FMCW, super-heterodyne or pulse radar that meets space qualification specifications. This reconfigurable transceiver will serve as the basis for the precipitation & cloud measurement doppler radar system that will be developed, tested and delivered to NASA in this Phase ...

Firefly, in collaboration with Rochester Institute of Technology, proposes an STTR program for the development of a wide-bandgap GaP-based space solar cell capable of efficient operation at temperatures above 300oC. Efficiency enhancement will be achieved by the introduction of InGaP quantum wells within the active region of the wide-gap base material. The introduction of these nanoscale features ...

Firefly, in collaboration with Rochester Institute of Technology, proposes an STTR program for the development of a space solar cell having record efficiency exceeding 40% (AM0) by the introduction of nanowires within the active region of the current limiting sub-cell. The introduction of these nanoscale features will enable realization of an intermediate band solar cell (IBSC), while simultaneous ...
