Annex A. Science And Technology Objectives (STOs)
Army Science and Technology Master Plan (ASTMP 1997)

IV.S.08. Tank Mobility Technology. By FY02, demonstrate critical engine, electric drive, track and suspension technologies to support the mobility field demonstration of the Future Combat System. The electric drive technology is developed through a joint coordinated effort among DARPA, Army, and USMC program offices. Specific products include: generators, storage devices (Flywheels, batteries, capacitors) and power electronics switching devices. All combat electric technologies will be demonstrated by the year 2002 in the lab and on a testbed. The engine development work will focus on high power density, low heat rejection single cylinder diesel engine technology efforts directed toward an extremely compact propulsion system. The track improvement will include advanced track and a track tension system. The advanced track will use nitrile rubber which will increase track pad life to 3,000 miles. Track retention will be actively controlled. Active control enables optimization of vehicle performance by reducing rolling resistance without increasing incidence of track misguide. Reduced rolling resistance requires less horsepower and reduces O&S costs by increasing fuel economy and track bushing life. The suspension technology development will include semiactive/active hydropneumatic and active electric suspension system. These mobility advances will enhance system survivability and operational effectiveness through smaller and lighter systems, improved ride quality, increased agility, improved platform stability, reduced acoustic and IR signatures, and silent operations capability.

By FY98, determine Active Suspension requirements and demonstrate SiC based switches. By FY99, demonstration of PEBB MOS controlled Thyristors. By FY00, identify and demonstrate advanced storage devices. By FY01, demonstrate track tensioner and nitrile track and demonstrate upgraded SiC devices. By FY02: (1) complete single unit active suspension lab testing; (2) demonstrate a single cylinder high power density engine of 1.5 hp/ and specific heat rejection of 18 BTU/hp-min; and (3) formulate FCS engine concepts and engine development approach selection. By FY03, demonstrate all electric Combat Vehicle technology on a testbed.

Supports: Future Combat Systems (FCS), Future Infantry Vehicle. Tank ICT.
