The invention discloses a water film cavitation and deicing fluid combined anti-icing fairing. The anti-icing fairing involves a fairing skin, a heating part, a cavitation bubble generation layer, a deicing fluid flow channel cover, a deicing fluid nozzle and a disc assembly; the heating part is positioned on the inner side of the fairing skin; the cavitation bubble generation layer is positionedon the outer side of the fairing skin; the deicing fluid flow channel cover is located on the inner side of the heating part and is provided with a deicing fluid flow channel cavity; the deicing fluidnozzle is connected with the deicing fluid channel cover, an outlet of the deicing fluid nozzle penetrates through the fairing skin, and the deicing fluid sprayed out of the deicing fluid nozzle canform the cavitation bubble generation layer on the outer side of the fairing skin; and the periphery of the disc assembly is connected with the fairing skin, the heating part and the deicing fluid channel cover so as to form a cavity for storing the deicing fluid. According to the water film cavitation and deicing fluid combined anti-icing fairing, the heated deicing fluid and the released hydraulic cavitation energy are applied to the fairing anti-icing technology, and therefore the heat energy of the deicing fluid, the heat energy released by the hydraulic cavitation and the impact vibrationenergy can be comprehensively utilized 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...
