Abstract

The invention discloses a water film cavitation and deicing liquid combined anti-deicing fairing, which comprises a fairing skin; a heating part, which is located inside the fairing skin; and a cavitation bubble generation layer, which is located in the fairing skin The outer side of the deicing fluid channel cover, which is located on the inner side of the heating part, has a deicing fluid channel cavity; the deicing fluid nozzle is connected with the deicing fluid channel cover, and the outlet of the deicing fluid nozzle passes through the rectifier Cowl skin, the deicing fluid sprayed from the deicing fluid nozzle can form a cavitation bubble generation layer on the outer side of the cowling skin; the disc-shaped part, whose peripheral edge is connected to the cowling skin, the heating part and the deicing fluid flow Road cover to form a cavity for storing de-icing fluid. The invention releases the heated deicing fluid and hydraulic cavitation energy and applies it to the anti-icing technology of the fairing, and comprehensively utilizes the heat energy of the deicing fluid, the thermal energy released by the hydraulic cavitation and the impact vibration energy to achieve the anti-icing purpose of the fairing.

Description

technical field [0001] The invention relates to the field of aviation anti-icing, in particular to an anti-icing fairing combined with water film cavitation and de-icing fluid. Background technique [0002] Icing on windward surfaces such as aircraft aeroengine fairings will seriously affect flight performance and reduce flight lift. Icing on aircraft fairings will cause ice accumulation to fall off and damage engine blades, and even cause aircraft loss of control. Anti-icing is invented and designed, and the anti-icing efficiency of the engine fairing is improved to reduce the chance of the fairing icing. [0003] The inventor believes that most of the existing fairing anti-icing devices use hot gas anti-icing technology. In recent years, ultrasonic anti-icing technology has been widely studied due to its high anti-icing efficiency. However, due to the huge airborne energy consumption, complex devices and large thermal inertia of hot gas anti-icing and ultrasonic anti-icin...
