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.

Abstract: Disclosed is a blower controller for controlling a blower that supplies a pressurised airflow to an air conditioning pack of an aircraft. The blower controller comprises a pack flow demand adjustment module configured to receive a pack flow demand signal representative of a desired mass flow rate of an airflow supplied by the air conditioning pack, and a blower condition signal indicative of a condition of an intake airflow received by the blower, and determine an corrected pack flow demand based on the pack flow demand and the blower condition signal. The controller also includes a first control signal generator configured to receive the corrected pack flow demand and generate a first control signal to control a first operating parameter of the blower in response to the corrected pack flow demand. Also disclosed is an environmental control system for an aircraft, including the blower controller.
