Description

The US Army Tank-automotive & Armament Command is conducting a Market Survey to identify the companies that can provide an Auxiliary Power Unit (APU) for the Abrams Main Battle Tank. The APU design shall permit easy integration into the tank. 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 6,500 ft. within the operating temperature range of the APU 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 visiblity SAE coarse dust. After 12 hrs of dust exposure, the APU shall provide 99% of full electric and hydraulic power to an altitude of 6,500 ft. The APU must draw its fuel from the vehicle's fuel cell and have a maximum consumption rate of 5 GPH. 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-integration Built-In Test (BIT)/Fault Isolation Test (FIT) diagnostics. The APU shall meet its performance requirement during and after a total of 2625 hrs (3 units -- 875 hrs each) of durablity testing. The APU, including mounting and interface hardware, shall be installed in the vehicle sponson within a space claim of 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 conditions. Detailed requirements are specific in Critical Item Development Specifications. Potential candidates will be evaluated based on life cycle cost and performance. Deviations from the performance requirements will be reviewed and considered if a substantial cost benefit can be shown and the operational impact is not too detrimental. For additional technical information, please contact the Technical POC: Murad Khan at khanm@tacom.army.mil. The Government will review all submitted statement of capabilities to determine market availablity of the required item. Submit information no later than 45 days after date of this announcement. Send requested information to Program Executive Office, Ground Combat & Combat Support Systems, ATTN: SFAE-GCSS-W-AB-CC, (Jenny Sterba) Warren, MI 48397-5000 or email sterbaj@tacom.army.mil.
