Testing of Ceramic Components in the Daimler-Benz Research Gas Turbine PWT 110 Free

The Daimler-Benz “Car 2000” research project included a two-shaft gas turbine which was used at speeds of up to 61,500 rpm and at temperatures of up to 1,250 °C (1st phase). Several ceramic components were pre-tested and used in the turbine engine both on the test bench and in the vehicle. The turbine engine has now reached a cumulative operating time of 600 hours; this includes 20,000 km on the road. Tested were HPSN components and other ceramic components which were manufactured in processes suitable for volume production. Some components have been tested on component test benches at temperatures of up to 1,350 °C. In the vehicle, temperatures of up to 1,350 °C were briefly encountered during acceleration.
