ATTAP/AGT101 ceramics technology update

The feasibility of applying ceramics to the gas turbine was demonstrated during the AGT101 Program, when over 250 hours were accumulated on ceramic components in engine tests at temperatures up to 1204C (2200F). The follow-on program, designated the Advanced Turbine Technology Applications Project (ATTAP), began in late August 1987 to further develop ceramic technology. This program addresses ceramic component fabrication technology, design methods development and the supporting data base, and verification of ceramic component durability in an operating engine environment. These technologies must be demonstrated so that a commercialization development decision can be made at the end of ATTAP.

Ceramics for the AGT101 automotive gas turbine

An advanced gas turbine powertrain for automotive application is being developed. Objectives of the program include a fuel consumption of 42.8 mpg on No. 2 diesel fuel in a 3000 pound car, same overall vehicle performance as obtained with a conventional spark ignition internal combustion engine, low emission, multiple fuel capacity, reliability, and competitive cost. The AGT101 powertrain consists of a power section, gearbox and transmission, and the design and analysis conducted thus far support the initial engine concept, as no significant design changes have been required. The ceramic rotor design approach and component materials are discussed, and it is projected that the AGT powertrain will be competitive with any other alternative powertrain in meeting the design objectives.
