Automotive gas turbine power plant
An automotive gas turbine which includes at least one power turbine rotor and at least one further turbine rotor driving at least one compressor, as well as a variable transmission for transferring energy from either of the rotors is described. The compressor rotor is made of lightweight material and the variable transmission is arranged in such a manner that the power transferring train from the transmission to the compressor rotor will obtain considerably less than moment of inertia than the power transfer train from the pertaining turbine rotor to the transmission. Last-mentioned portions of the power transfer train will thus form a rotatable body, the inertia of which is connectable to the compressor rotor, for instance, during starting or acceleration. If a further turbine rotor is directly connected to the compressor rotor, this further turbine rotor is made of ceramic material, which has a low specific weight, and will not noticeably increase the moment of inertia of the compressor unit; a main point in the arrangement is that the inertia-providing body is rotatable independently of the power output shaft, so it may be kept in readiness even when a vehicle is stopped.
