Abstract
A gear box is provided with three inputs mutually decoupling each other so that neither can drive the other two via the gear box but either can drive secondary power sources such as a pump and a generator. The three inputs are respectively connected to an aircraft engine shaft, a starter-air turbine and a gas turbine, whereby additionally the starter turbine is connected to drive the shaft for starting but not vice versa. The air turbine receives air from the compressor of the gas turbine or otherwise. The shaft can be disconnected from the system.
