An automatic speed change system for a two-shaft type gas turbine engine, employed in an automotive vehicle as a prime mover thereof, is capable of varying a speed change ratio depending upon the engine driving condition. The automatic speed change system adjusts a revolution speed of a power turbine of the gas turbine engine to maintain a high efficiency at an engine idling condition while maintaining a low fuel consumption at an acceptably low level to obtain enhanced standstill acceleration characteristics without a worsening of the fuel consumption.
An automatic speed changing system for a two-shaft type gas turbine engine having a gas generator including a compressor and a compressor turbine arranged coaxially on a first shaft with sid copressor, a combustion chamber, a variable nozzle, and a power turbine rotatable about a turbine shaft independently of the first shaft of said compressor and said compressor turbine, said system comprising: an automatic speed change mechanism disposed between an output shaft of said power turbine and an input shaft of a power transmission device, said automatic spe...
