IMPROVED SYSTEM FOR THE DUAL MANAGEMENT OF ANTI-ICING AND BOUNDARY-LAYER SUCTION ON AN AEROFOIL OF AN AIRCRAFT

摘要

According to the invention, for the dual management of anti-icing and boundary-layer suction, the invention proposes a system for an aerofoil (4) of an aircraft, including: a channel (42) having a double function of anti-icing and boundary-layer suction; a double-function main pipe (30) to which a device (26) for monitoring the boundary-layer suction and a device (28) for monitoring anti-icing are connected; an anti-icing air-intake pipe (38) connecting the main pipe (30) and the channel (42); a non-return valve (50) enabling the anti-icing air to go from the main pipe (30) to the pipe (38); at least one suction-air collection pipe (56) connecting the channel (42) and the main pipe (30); and a non-return valve (60) enabling the suction air to pass from the pipe (56) toward the main pipe (30).
