Abstract

The invention discloses combined deicing system and method based on detection of ice layer-skin surface bonding state. The combined deicing system and method based on detection of ice layer-skin surface bonding state are used for removing ice accumulated on the surfaces of aircraft wings. The combined deicing system bonding state sensors arranged on inner skin of wings, heating units, an icing sensor and excitation modules and correspondingly comprises, a heating control unit, a signal conditioning unit, an excitation control unit and the like. According to signals from the bonding state sensors and temperature sensors, the information of the ice layer-skin surface bonding state can be obtained, and the appropriate deicing time can be mastered according. By adopting the method combining heating and excitation, a safe and efficient deicing with low energy consumption is achieved. Compared with a pure electric-heating deicing method, energy consumption is low, and the exciting force for exciting deicing is smaller than the exciting force of pure exciting deicing, therefore, damage to wing skin materials is small, and the effect on the aircraft aerodynamic shape is smaller.

Description

technical field [0001] The invention belongs to the field of aircraft icing detection and anti-icing, and more specifically relates to a composite deicing system based on the detection of the combined state of the ice layer and the skin surface and adopting the combination of heating and exciting vibration. Background technique [0002] Aircraft icing will have adverse effects on its aerodynamic shape, engine power, control surface operation performance, brakes, landing gear operation, external vision, flight instrument readings, etc., and even cause flight accidents in severe cases. [0003] At present, typical aircraft anti-icing technologies are divided into three categories: mechanical vibration deicing, thermal anti-icing, ultrasonic deicing, etc. Mechanical deicing requires a large amount of energy to vibrate the wings, and will cause varying degrees of damage to the aerodynamic shape of the aircraft. Thermal anti-icing methods include two main methods: electric anti-...
