The report presents the results of an in-depth study for identifying an improved gas turbine for automotive applications. The study was performed by the Ford Motor Company and AiResearch Division of the Garrett Corporation under contract to DOE/NASA. The principal specified objectives of this contract were: (1) fuel economy a minimum of 20% better than 8.3 km/l (19.6 mpg) for a 1542 kg (3400 lbs.) test weight baseline vehicle, when tested over the Combined Federal Driving Cycle at emissions objectives of .41 gm/mi HC, 3.4 gm/mi CO, and .4 gm/mi NO/sub x/; (2) acceleration capability of 15 sec from 0 to 96.5 km/hr. (0 to 60 mph); and (3) a design capable of reaching a level of development in 5 yrs (by the year 1983) such that a decision to start a production program could be considered; additionally, Ford requirements for the engine were a fuel economy objective of 30 to 50% better than the baseline vehicle, and a 4 sec vehicle start-up distance of 19.5 m (64 ft.). Investigations for an improved gas turbine system identified twenty-two candidate engine concepts. These were examined judgementally, based on the previous experience of both contracting companies, and were ranked for fuel economy, cost packageability, risk of a long development program, and driveability feel. Double weight was assigned to the cost and fuel economy. (ERA citation 05:004719)
