THE PROBLEMS OF ATTENUATING DUCTED NOISE AND DISTRIBUTED NOISE ARE ADDRESSED USING ACTIVE NOISE CANCELLATION TECHNIQUES. FOR DUCTED NOISE, A COMBINATION OF COMMERCIAL ANC EQUIPMENT WITH LOW PRESSURE DROP MUFFLERS IN AN SVS PROPRIETARY CONFIGURATION WILL BE EXAMINED. COST AND PERFORMANCE TRADES BETWEEN THE ACTIVE CONFIGURATION AND PASSIVE MUFFLERS WILL BE MADE AND AN EXPERIMENT WILL BE DESIGNED FOR ...

THE U.S. MARINE CORPS HAS A CRITICAL NEED FOR A NEW, STATE-OF-THE-ART SYSTEM FOR ARMAMENT CARRIAGE ON ITS AH-1W ATTACK HELICOPTER. THIS PHASE I EFFORT WILL PERFORM A TRADE/CONCEPTUAL DESIGN STUDY TO SYSTEMATICALLY IDENTIFY THE BEST DESIGN SOLUTION. THE MERITS, COSTS, AND RISKS ASSOCIATED WITH AN INNOVATIVE DESIGN SOLUTION (CONFORMAL WEAPONS PODS) WILL BE COMPARED TO MORE CONSERVATIVE DESIGN SOLUTI ...

N/A

A roadmap for affordability will be developed in Phase I based on Robust Design Simulaton(RDS) which will be applied in Phase II to address affordability design tradeoffs for propulsion system technologies in V/STOL aircraft. The V-22 tilt rotor aircraft with the T-406 engine will be used as the baseline V/STOL aircraft for affordability measurement verification and validation of the RDS. The pr ...

WOOD AND RESIN MATRIX COMPOSITE PROPELLERS FOR UNMANNED AIR VEHICLES SUFFER UNACCEPTABLE EROSION DAMAGE DUE TO LIQUID AND SOLID IMPACT. POLYMERIC PROTECTIVE COATINGS ARE INEFFECTIVE IN SOLID PARTICLE ENVIRONMENTS. THE BROAD DAMAGE AREA OF PROPELLERS MAKES METALLIC PROTECTIVE COATINGS, SUCH AS HAVE BEEN DEVELOPED FOR HELICOPTER BLADES, UNACCEPTABLE FROM A WEIGHT PENALTY. CONVENTIONAL CERAMIC COATIN ...

N/A

A feasibility investigation is proposed for designing a HIRF aircraft test facility which reduces existing test time by at least a factor of two without comprising the HIRF requirements for aspect angle/polarization and field strengths (both average and peak). SEA proposes a hybrid TEM cell/reverberation facility which will reduce test time involved with repositioning test equipment or test ...

HIGH-VALUE TEST ITEMS ARE OFTEN LOST IN OPEN-OCEAN TEST AND PRACTICE RANGES. SUCH ITEMS INCLUDE WEAPONS, FLIGHT DATA RECORDERS, MISSILES, DRONES, AND MANNED TACTICAL AIRCRAFT. THE LOSS OF VALUABLE TEST DATA CAN BE A SERIOUS PROBLEM. IN ADDITION, RECOVERY OF SOME ITEMS BY FOREIGN GOVERNMENTS NOT ONLY COMPROMISES WEAPON TECHNOLOGY, BUT CAN RENDER AN ENTIRE WEAPON SYSTEM SUSCEPTIABLE TO FOREIGN COUNT ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

The Virtual Engineering firm is a reality, with a team of scientists and engineers scattered at home sites working together to solve tough engineering problems. This SBIR will perform research and development to provide collaborative system engineering tools for network engineering projects. We will explore new directions for collaborative systems engineering (SE) that enable distributed req ...
