Fasteners/Rivets for Watertight Integrity and Corrosion Prevention in Permanent Application

BOSCH Aerospace, Inc., a service connected disabled veteran-owned small business, is pleased to submitthis proposal to develop and demonstrate an efficient, low-noise, low-maintenanceair management system for shipboard ventilation. The concept is adapted from theVertical Takeoff and Landing aircraft Cycloidal Propeller (CycloProp) development currentlyunderway in SBIR Phase II Contract N68335-00-C-0201.CycloProp geometry places wing sections into rotation in a paddlewheel manner. In thisgeometry, air velocity is equal at all points across each wing's span. During rotation, thewing's angle-of-attack is changed in the sector of rotation requiring air acceleration.The result is very high-thrust and low noise at rotational speeds of about 20% ofconventional propellers. CycloProp has demonstrated thrust of over 12 lbs/HP versus aboutthree pounds for conventional propellers. This low-speed, high-thrust capability means lesswear on bearings, lower energy consumption, low noise and lower maintenance.The research phases are: Engineering/Design, Fabrication/Integration, Testing/Demonstration.The project documentation will include design drawings, test reports, video, photographs andmonthly Cost Performance Reports.Success will be exploited in the commercial sector whereSuccess will be exploited in the commercial sector where low-noise, efficient airmovement systems are in demand. Benefits include low noise, low power consumption,high efficiency, and low wear on components, thus low maintenance. Commercialapplications include worldwide forced air heat and cooling, electronic coolingapplications in space, and other high-volume, low-pressure air or gas movementapplications.
