Conceptual design study of an improved automotive gas-turbine powertrain. Final report
- eds.
This is the third of four volumes of the contract final report which summarizes all of the work performed in a government-sponsored Automotive Gas Turbine Development Program. In this third volume of the contract final report, an assessment is made of the potential for developing an Improved Gas Turbine (IGT) propulsion system. The design was based on the application of current and near-term technology in a concept targeted to enter production development by 1983. The study was directed toward defining automotive gas turbine concepts with significant technological advantages over the spark ignition (SI) engine. Possible design concepts were rated with respect to fuel economy and near-term application. A program plan was prepared which outlines the development of the IGT concept that best met the goals and objectives of the study. Identified in the program plan is the research and development work needed to meet the goal of entering a production engineering phase by 1983. The fuel economy goal of the study was to show at least a 20% improvement over a conventional 1976 SI engine/vehicle system. On the bases of achieving the fuel economy goal, of overall suitability to mechanical design, and of automotive mass production cost, the powertrain selected was a single-shaft engine with a radial turbine and a continuously variable transmission (CVT). Design turbine inlet temperature was 1150/sup 0/C. Reflecting near-term technology, the turbine rotor would be made of an advanced superalloy, and the transmission would be a hydromechanical CVT. With successful progress in long-lead R and D in ceramic technology and the belt-drive CVT, the turbine inlet temperature would be 1350/sup 0/C to achieve near-maximum fuel economy.
