A power transmission arrangement comprises a first power transmission member connectable to a first main shaft of an engine. The arrangement also includes a second power transmission member connectable to a second main shaft of the engine and to a third power transmission member. A coupling assembly is provided which has a selectable coupling condition to couple the first power transmission member to the second power transmission member to allow power to be transmitted from the third power transmission member to the first main shaft of the engine via the first power transmission member. The coupling assembly has a decoupling condition to decouple the first power transmission member from the second power transmission member to allow power to be transmitted from the main shaft of the engine to the third power transmission member via the second power transmission member.
A power transmission arrangement for a gas turbine engine having in axial flow series a first stage compressor, a second stage compressor, a first stage turbine and a second stage turbine, a first main shaft connecting the first stage turbine to the second stage compressor so that the first stage turbine drives the second stage compressor during operation of the engine, and a second main shaft connecting the second stage turbine to the first stage compressor so that the second stage turbine drives the first stage compressor during operation of the engine, said power transmission arrangement comprising:
A power transmission arrangement for a gas turbine engine, said gas turbine engine comprising:
