25 -- LIGHTWEIGHT DIESEL ENGINE DRIVEN AUXILIARY POWER UNIT (APU) FOR THE AAAV DUE 030999 POC Mr. Terry G. Dubois, (703) 492-3349 MARKET RESEARCH: The Direct Reporting Program Manager (DRPM) for the Marine Corps Advanced Amphibious Assault Vehicle (AAAV) is conducting market research to determine the commercial availability of a lightweight diesel engine driven Auxiliary Power Unit (APU) for the AAAV. The Marine Corps wants to purchase a sufficient number of lightweight APUs to carry out validation testing. APUs must be available by 1 March 2000 in order to conduct testing prior to selection. For the purposes of this announcement the APU assembly shall consist of the following: Diesel engine prime mover, electric generator, hydraulic pump, fuel control hardware including injection pump(s), fuel pump, fuel lines, controls required for proper operation, 24 Vdc electric starter, electronic governor/voltage regulator, glow plugs, coolant temperature transducer, internal wiring harness providing interconnection between APU and vehicle, and all connecting lines for exhaust, hydraulic, and air induction. The APU shall have a power output of no less than 330 Amps @ 28Vdc of electrical power and 1.9 gpm hydraulic power at 3500 psi. Overall weight of the unit shall not exceed 225 lbs. and the APU assembly must fit within an envelope of 607 mm long by 487 mm wide by 760 mm high. The acoustic signature for the APU unit with enclosure shall not exceed 53 dBa when measured from a distance of 7 meters. Because the APU contributes to the AAAV main engine preheating system, it is desired that the APU engine be water-cooled and that the electric generator also be water-cooled. The APU shall be capable of operating on diesel fuels (DF-2, DF-A) and JP-8 and shall be compatible with 15W-40 lubricant. The APU must be able to withstand the extreme environmental conditions, as well as, vibration and shock loads associated with tracked vehicles. Additional information is available on the AAAV web page (http://www.aaav.hqi.usmc.mil) or can be requested through email to the following address: aeng@notes.hqi.usmc.mil. The AAAV point of contact is Mr. Terry DuBois (703) 492-3349. The closing date for this request is 9 March 1999. Companies with existing APUs or currently developing APUs that would meet or exceed the above requirements should provide design characteristics and performance data to: DIRECT REPORTING PROGRAM MANAGER, AAAV, ATTN: Mr. William S. Story, Department 240, 991 ANNAPOLIS WAY, WOODBRIDGE, VA 22191-1215. THE SUBMISSION OF THIS INFORMATION IS NOT TO BE CONSTRUED AS A COMMITMENT BY THE GOVERNMENT TO PAY FOR THE INFORMATION RECEIVED. NO SOLICITATION DOCUMENT EXISTS. Posted 02/09/99 (W-SN296405). (0040)
