ABSTRACT:
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.
