Progress is reported for a program to demonstrate by 1976 an experimental gas turbine powered automobile which meets the 1976 Federal Emission Standards, has significantly improved fuel economy, and is competitive in performance, reliability, and potential manufacturing cost with the conventional piston engine powered, standard-size American automobile. Procurement delays have caused an additional one-month slippage in engine deliveries. All test cell conversion and preparation tasks are complete. Assembly, qualification, and delivery to NASA of Engine 3 were accomplished. Vehicle installation design tasks were completed. Vehicle structural modifications were completed. Initial operation of the first vehicle has slipped two weeks due to engine delivery schedule changes. The planned training activity for the NASA technician took place. Endurance activity has included continued testing of molded insulation and the start of testing of new coarse pitch regenerator drive gears. Testing of a variable geometry combustor for control schedule optimization started. The all-ceramic regenerator core program was formulated, and work started on design and fabrication or procurement of core, drive, and seal hardware required specifically for these cores. The integrated control system sub-contract is delayed pending resolution of the adjustments to the scope of work. An elasto-plastic stress analysis program is being written in support of design efforts associated with the low cost turbine wheel manufacturing process development. The torque converter lock-up program was defined and hardware procurement started. The original test request for free versus geared gas generator rotor evaluation was completed. A preliminary analysis of the test results was made. (ERA citation 01:019812)
