28 -- REQUEST FOR INFORMATION ON GASOLINE ENGINES POC Contact, Amy Timmermann, Phone (703)604-0903 As part of a market survey, the Naval Air Systems Command (NAVAIR) is interested in obtaining information on gasoline engines which are suitable for application in Unmanned Aerial Vehicles (UAVs). The desired engine should be in production and require only limited modifications for adaptation and integration. The engine application is as a pusher type propulsion and power system. The complete system, including intake, exhaust, cooling and gear drive hardware should weigh no more than 90 pounds. The engine may be either liquid or air cooled in design. The Government is particularly interested in engines with the following basic characteristics: -Operating Altitude: -21 to +49 deg C required. -- -Horsepower to Propeller: 60 hp @ 5,800 rpm take-off (60 sec at sea level) 50 hp @ 5,400 rpm (continuous at sea level) -- Operating rpm: 1000-5800 rpm required 600-5000 rpm desired -Specific Fuel Consumption (SFC):75 @ lbs/hp-hour max continuous, 5 lbs/hp-hour (Or less) desired -Fuel:mogas (90 MON/RON OCTANE) -Max Installed Weight (includes base engine, exhaust system, fuel system, accessories (oil pumps, water pumps, cooling system, etc.) and gear drive, if required): 95lbs, 75lbs desired -Time Between Overhaul (TBO): TBD hours. We ask that your response include the following data (in all cases, please state whether the information is predicted or demonstrated/actual): -Basic engine configuration -- -Gear box is engine is not direct drive -Power output and propeller speed at both maximum power and design cruise conditions -Plot depicting Fuel Consumption (SFC) vs. Horse Power-Engine power lapse with altitude -Installed engine dimensions and volume footprint, including required accessories -Engine weight with required accessories (less propeller) including center of gravity -Propeller, if integral to the system -Time Between Overhaul (TBO) -Method accessories (fuel injection pump, oil pump, coolant pump, alternators, etc.) are driven? -Method engine started including low temperature (-25 deg C) strts -Total time accumulated to date -- -Number of engines built and applications -Engine control logic. In addition to the above information, we desire information on the engine development status (design verification testing, design/configuration stability, production status, status of required drawings/blueprints, etc.) and an estimate of production cost. It is anticipated that data derived from this RFI will be used to develop a list of potential vendors for procurement of 32+ engines for a flight demostration program. Interested parties should submit a written statement of interest, including a description of the item considered to meet the criteria stated herein, with the above requested supporting data, within 21 days of publication of this announcement to: Commander, Naval Air Systems Command, Attn: AIR-2.4.2.5, 1421 Jefferson Davis Highway, Arlington, VA 22243-2170. FAX: (703)604-1236. In addition to Government review, RFI responses will be provided to Alliant Techsystems, Inc. for its review in support of the Government's assessment. -- NAVAIR Synopsis No. 40024-97. (0043)
