28 -- MARKET SURVEY FOR AUXILIARY POWER UNIT POC Jenny Sterba (810) 574-5526 E-MAIL: Click here to contact the POC, sterbaj@tacom.army.mil. THIS IS A MARKET SURVEY ONLY. THIS IS NOT A SOLICITATION FOR PROPOSALS OR INVITATION FOR BIDS. The U.S. Army Tank-automotive and Armaments Command is conducting a Market Survey to identify the companies that can provide an Auxiliary Power Unit (APU) for the Abrams Main Battle Tank. This APU must be a Commercial Off The Shelf item (COTS) requiring no further development. Government Research and Development funds are not available for developing any portion of this item. The APU shall interface with existing tank subsystems to provide auxiliary electric and hydraulic power during tank main engine off operations. The APU must be capable of providing a minimum of 6 kw of electric power regulated to 28 vdc and 1650 PSI hydraulic pressure at a flow of 14.1 GPM. The APU must be capable of providing full electric and hydraulic power to an altitude of 12,000 feet. Full electric power is required to an altitude of 15,000 feet. To maintain full electric output power to an altitude of 15,000 feet, the hydraulic output power may be reduced. The operating temperature range of the APU is from minus 25 degrees F to plus 125 degrees F without special adaptive kits. The APU shall provide its own air filtration system which protects the unit from exposure to 0.5 times zero visibility SAE coarse dust. After 12 hours of dust exposure, the APU shall provide full electric and hydraulic power to an altitude of 6500 feet. The APU must draw its fuel from the vehicle's fuel cell and have a maximum consumption rate of 5 GPH of JP-8. The APU shall be capable of being controlled at a crewstation within the vehicle. Control functions shall include start, stop and emergency stop functions. The APU shall support tank-integrated Built-In Test (BIT)/Fault Isolation Test (FIT) diagnostics. The APU shall meet its performance requirements during and after 2500 hours of durability testing. The APU, including mounting and interface hardware, shall be installed in the vehicle sponson within a space claim 49 inches long, 21 inches wide, and 12 inches high. The sponson may be ventilated to provide compartment cooling. If the sponson is ventilated, the exhaust air shall use the same opening as the APU exhaust. The APU shall be designed for ease of maintainability, i.e., access to air filter, oil filter and fuel filter. The APU exhaust plume in the 3-5 micron band, measured along a line perpendicular to the exhaust plume centerline at a distance of 36 inches, shall not exceed 75 degrees Centigrade under any engine load condition. Detailed requirements are specified in Critical Item Development Specifications. For additional technical information, please contact the Technical POC, Gary Gerlach at EMAIL gerlachg@tacom.army.mil. The Government will review all submitted statement of capabilities to determine market availability of the required item. Submit information no later than 30 days after date of this announcement. Send the requested information to Program Executive Office, Ground Combat and Support Systems, ATTN: SFAE-GCSS-W-AB-CC, (Jenny Sterba) Warren, MI 48397-5000 or EMAIL sterbaj@tacom.army.mil.
