DEICING DEVICE FOR WING LEADING EDGE OF AIRCRAFT AND AIRCRAFT MAIN WING

摘要

Disclosed are a deicing device for the leading edge of the wing of an aircraft and an aircraft main wing, which are configured by being provided with: a warm air path (46) which is formed along the inside of the curved leading edge (41) of a main wing by means of the leading edge (41) of the main wing, and a curved guiding plate (42) disposed on the inside of the leading edge (41) of the main wing with a predetermined space therebetween; and a duct pipe (47) for supplying breed air to the warm air path (46). The gap at the tip end section of the leading edge (41) of the main wing in the warm air path (46) is formed to be narrower than the gap at the downstream side of the flow direction of the breed air. As a consequence, the leading edge of the wing is effectively heated, thereby properly preventing ice from forming on the outside of the leading edge of the wing.
