Compound deicing fluid and gasbag anti-icing system

Abstract

The invention belongs to the field of plane airfoil deicing, and particularly relates to a compound deicing fluid and gasbag anti-icing system. The compound deicing fluid and gasbag anti-icing systemcomprises a controller (1), a deicing fluid tank (2), a pump machine (3) and a gasbag deicing assembly (4), wherein the gasbag deicing assembly (4) comprises a deicing gasbag (5) and an air flow distribution device (6), step-shaped sunken parts are arranged at the transition portion of both a deicing fluid spraying area and a gasbag deicing area of the upper surface and the lower surface a wing face front edge (7), and several micro holes (8) are formed around the wing face front edge and the side faces of the step-shaped sunken parts. By means of the compound deicing fluid and gasbag anti-icing system, through a compound anti-icing mode, the wing face deicing efficiency is improved, and the air safety margin under an icing environment is increased.

Description

technical field [0001] The invention relates to the field of aircraft wing surface deicing, in particular to a composite anti-icing fluid-airbag anti-icing system. Background technique [0002] After the aircraft enters the icing environment, ice will accumulate on the leading edge of the aircraft wing, which will affect flight safety. Existing anti-icing methods include anti-icing fluid anti-icing systems, air bag de-icing systems and the like. The anti-icing fluid anti-icing system will not affect the aerodynamic performance of the airfoil, and the energy consumption on the aircraft is small, but at the same time, due to the limited amount of anti-icing fluid, the anti-icing time is limited (especially when the anti-icing area is large. ), and the loading of anti-icing fluid reduces the effective load of the aircraft; the airbag deicing system has a simple structure, a small system weight, and less energy consumption on the aircraft, but residual ice is likely to be gener...

The anti-icing fluid anti-icing system will not affect the aerodynamic performance of the airfoil, and the energy consumption on the aircraft is small, but at the same time, due to the limited amount of anti-icing fluid, the anti-icing time is limited (especially when the anti-icing area is large. ), and the loading of anti-icing fluid reduces the effective load of the aircraft; the airbag deicing system has a simple structure, a small system weight, and less energy consumption on the aircraft, but residual ice is likely to be generated on the airfoil after deicing, which affects the aerodynamic performance of the airfoil

Due to the completely different structures of the anti-icing fluid anti-icing system and the airbag deicing system, and the difference in anti-icing control timing, it is difficult to develop a composite anti-icing fluid-airbag anti-icing system, and it has no application in active aircraft
