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

摘要

A deicing device for a wing leading edge of an aircraft and an aircraft main wing are constituted by providing a hot air passage (46) by a curve-shaped main-wing leading edge (41) and a curve-shaped guide plate (42) arranged inside the main-wing leading edge (41) with a predetermined space therefrom, along an inner side of the main-wing leading edge (41), as well as by providing a duct pipe (47) that supplies bleed air to the hot air passage (46), in which in the hot air passage (46), a space at a distal end of the main-wing leading edge (41) is formed to be smaller than that on a downstream side in a bleed-air flowing direction. With this configuration, by heating a wing leading edge effectively, it is possible to appropriately prevent formation of ice adhering to an outer side of the wing leading edge.
