The ultimate aim of this program is to experimentally demonstrate the ability of a passive, light weight flow control device to successfully produce acceptable acoustic noise levels in the main cavity of the F/A-22 aircraft during a flight test. The Phase I effort performed both state of the art CFD analysis and complementary small-scale wind tunnel tests to assess the ability of a rod-in-crossflo ...

A VARIATIONAL TECHNIQUE WILL BE USED TO COMPUTE THE ELECTROMAGNETIC FIELDS OF TRAVELING WAVES IN A HELICAL SLOW-WAVE CIRCUIT WITH HELICAL DIELECTRIC SUPPORT. BY GENERALIZING THE TRIAL FIELDS FROM THOSE USED IN AN EARLIER STUDY AND BY APPLYING POINT- MATCHING CONSTRAINTS, AN EFFICIENT COMPUTATION WILL BE DEVELOPED FOR THE PAHASE VELOCITY, INTERACTION IMPEDANCE, AND CHARACTERISTIC IMPEDANCE OVER A C ...

The plasma generated around low altitude hypersonic vehicles is a serious impediment to vehicle communications, particularly GPS navigation signal reception. This problem has introduced a critical path failure and potential showstopper for the hypersonic cruise missile program. The HyPASS system will simultaneously decrease the signal loss due to the plasma in such a vehicle and provide important ...

This proposal seeks to provide a novel electric propulsion option that will offer significant performance advantages over the current state of the art and surpass the IHPRPT Phase III goals for electrostatic propulsion. This will be accomplished by combining the efficient ionization mechanism of a helicon source with the favorable plasma acceleration properties of a Hall thruster. By utilizing the ...

The Small Business Technology Transfer Research (STTR) Phase I project will investigate the production of silane gas (SiH4) and photovoltaic-grade silicon (Sipv) from high silicon content agricultural waste. Current solar cell production struggles against the tremendous cost and complexity of refining Sipv or its more valuable gaseous pre-cursor SiH4. It is believed that the application of electro ...

A novel damping model to damp acosutic pressures in gas turbine afterburners is proposed for development and validation in this SBIR project. The proposed model will account for as many of the physical phenomena present in the afterburenr as possible which will include grazing, bias, and mean flows, and heat release fluctuations that excite certain pressure modes and potentially cause screech.

This Small Business Innovation Research Phase I research project initiates the development of a new class of wireless miniature smart sensor labels that continuously track and record exposure to the environmental conditions, and directly store the sensed data in digital Complementary Metal Oxide Semiconductor (CMOS) non volatile memory without requiring any battery. These batteryless CMOS-sensor m ...

This Small Business Technology Transfer (STTR) Phase I project addresses the need for novel catalytic systems for electrochemical energy conversion technologies, specifically polymer electrolyte membrane (PEM) fuel cells, through an innovative bilayer electrocatalyst design and the ability to implement that design using a sophisiticated electrodeposition process. The project will demonstrate impro ...

A quad petal wide band horn is proposed with improvements over prior similar designs to meet all the requirements of the solicitiation. The horn offers dual independant polarizations with high cross pol. isolation so the antenna does not need to be rotated for multi-pol. measurements. The improvements help to minimized back and side lobes while enhancing the gain towards achievement of the require ...

This SBIR Phase I project will focus on the development of a thermally activated cross-linkable thermoplastic adhesive film. Although many thermoplastic adhesive films are available, none are capable of being cross-linked as they are applied. The addition of the cross linking functionality will allow the bonded joints thus created to be used at a higher temperature, closer to the original film mel ...
