【発明の名称】航空機用着氷防止装置
Document Type and Number:
Japanese Patent JP3174072
Kind Code:
B2
Abstract:
An anti-icing system for leading edges (12) of an aircraft. Hot compressed air is discharged from a cavity behind the leading edge (12) through a multitude of small holes in the leading edge skin (30) 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.
