The generator (32) is also connected by a second sprag clutch (36) to an air turbine (38) connected to engine bleed valves (12) which are selectively open when the engine speed falls below a predetermined level. The clutches (34,36) are arranged such that the generator (32) is driven at any time by the fastest rotating of the gearbox (22) and turbine (38).",
