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.
本发明公开了一种基于冰层‑蒙皮表面结合状态探测的复合式除冰系统和方法,用于除去飞机机翼表面附着的积冰。所述系统包括用于安装在机翼内蒙皮上的结合状态传感器、加热单元、结冰传感器、激振模块,还包括相应的加热控制单元、信号调理单元和激振控制单元等。所述方法根据结合状态传感器以及温度传感器的信号,获取冰层‑蒙皮表面的结合状态信息,从而掌握恰当的除冰时机,采用加热与振动相结合的方法,实现安全、高效、低能耗的除冰。本发明比单纯的电加热除冰方法耗能少,采用的激振除冰的激振力比单一的激振除冰的激振力小,故对机翼蒙皮材料的损伤要小,对飞机的气动外形影响更小。
