Abstract
A system for providing active flow control in an aircraft having a gas turbine engine. The system includes an environmental control system that includes a cabin blower system having a compressor operable to compress a fluid delivered by a fan section of the gas turbine engine to generate a pressurised fluid for use by the environmental control system. The environmental control system is fluidicly connected to an active flow control system via a fluid supply line, for allowing the pressurised fluid generated by the compressor to be supplied to the active flow control system so that it can be ejected from the aircraft across an exterior surface of a movable control element of the aircraft.
Claims14
A system for providing active flow control in an aircraft having a gas turbine engine, the system comprising:
- an environmental control system that includes a cabin blower system, the cabin blower system comprises a compressor that is configured to compress a fluid delivered by a fan section of the gas turbine engine to generate pressurised fluid for use by the environmental control system;
- an active flow control system configured to eject pressurised fluid out of the aircraft across an exterior surface of a movable control element of the aircraft;
- and
- an auxiliary power unit configured to generate an auxiliary pressurised fluid when the cabin blower system is inactive, the auxiliary power unit being fluidicly connected to the environmental control system via a supply conduit for supplying the environmental control system with the auxiliary pressurised fluid when the cabin blower system is inactive,
- wherein the environmental control system is fluidicly connected to the active flow control system via a fluid supply line to allow at least some of the pressurised fluid generated by the compressor to be supplied to and used by the active flow control system, and
- the supply conduit forms at least a part of the fluid supply line that fluidicly connects the environmental control system and the active flow control system.
