A system for dual management of anti-icing and boundary layer suction for an aerofoil of an aircraft, including: at least one anti-icing channel and at least one suction channel; a device monitoring boundary layer suction and a device monitoring anti-icing; a first duct collecting the suction air communicating with the suction channel and a second duct supplying anti-icing air connected to the device and communicating with the anti-icing channel; a three-way valve to which the first duct, a suction duct, and a duct for discharging the anti-icing air are connected; and a duct collecting anti-icing air connected to the anti-icing channel, and to the first duct.

System for dual management of anti-icing and boundary layer suction on an aerofoil of an aircraft, including a function of collecting the anti-icing air

For dual management of anti-icing and boundary-layer suction, a system for an aerofoil of an aircraft, including: a channel having a double function of anti-icing and boundary-layer suction; a double-function main pipe to which a device for monitoring the boundary-layer suction and a device for monitoring anti-icing are connected; an anti-icing air-intake pipe connecting the main pipe and the channel; a non-return valve enabling anti-icing air to go from the main pipe to the pipe; at least one suction-air collection pipe connecting the channel and the main pipe; and a non-return valve enabling suction air to pass from the pipe toward the main pipe.
