초록

A system, which may be a propulsion system or a vehicle having a propulsion system, for example, an air-vehicle, a land vehicle or a marine vehicle, includes a gas turbine engine operative to drive a propulsor. The propulsor may be, for example, a fan/turbofan, a propeller, a turbine, or any rotor system for propelling an aircraft; a system for providing tractive effort for a land vehicle, such as one or more transmissions and wheel/track systems; and/or may be one or more marine propulsive devices, such as shrouded or unshrouded propellers, hydrojets an...

청구항

1. A propulsion system for a vehicle, comprising: a gas turbine engine having a high pressure spool and a low pressure spool, wherein the low pressure spool is configured to mechanically drive a propulsor, wherein the propulsor is configured to impart motion to the vehicle during normal vehicle moving operations; andan auxiliary power unit (APU) mechanically coupled to only the low pressure spool, wherein the APU is a thermodynamic machine operative to mechanically supply rotational power to the propulsor; anda controller configured to selectively engage...
