Abstract

An anti-icing system for leading edges of an aircraft. Hot compressed air is discharged from a cavity behind the leading edge, through a multitude of small holes in the leading edge skin into the airflow impinging on the leading edge. In a first embodiment the anti-icing system utilizes part of the air distribution system in existence for a laminar flow control system. Instead of sucking air into the wing, as is done in the laminar flow control mode, the flow is reversed in the anti-icing mode, blowing hot compressed air out of the wing. In a second embodiment the anti-icing system is used solely in the anti-icing mode.
