ABSTRACT:
A marine gas turbine engine including a fluid coupling between its low pressure turbine and power turbine. During forward drive the fluid coupling is drained so that the exhaust gases from the low pressure turbine drive the power drive in a first direction of rotation. For reverse drive, the fluid coupling is filled so as to couple the low pressure turbine and power turbine and cause the power turbine to rotate in the opposite direction of rotation. When the fluid coupling is operational, the compressor delivery air and low pressure turbine exhaust gases are exhausted to atmosphere.
