Abstract

The invention discloses a deicing device, system and method for an aircraft wing. According to the technical scheme, the deicing device comprises at least one deicing unit; the deicing unit comprisesa plurality of groups of transducers, and each group comprises two transducers; an electromagnetic coil sleeves the outer side of each group of transducers, the electromagnetic coils are connected inparallel and are connected with a precision pulse generator, and the precision pulse generator is connected with a controller; the controller is further connected with a temperature sensor and a thickness detector. By means of high-frequency oscillation of the giant magnetostrictive material and generated instant high-heat-density anti-icing and de-icing, an ice layer at a specific part of a wingin the flying process of an airplane can be effectively removed in real time; and the deicing time is shortened and the energy consumption is greatly reduced while the flight safety of the aircraft iseffectively ensured.

Description

technical field [0001] The invention relates to the field of aircraft deicing, in particular to a deicing device, system and method for aircraft wings. Background technique [0002] Aircraft flying in cold and humid air, such as clouds, wet snow, freezing rain, fog, and high-humidity air with a temperature around zero degrees Celsius, the surface of the body, the leading edge of the wing, and other parts of the aircraft may have different degrees of damage. freeze. A large number of theoretical calculations, wind tunnel tests and flight tests have shown that if there are no anti-icing / de-icing measures for aircraft components, the icing of these components can lead to serious deterioration of aircraft aerodynamic characteristics and stability characteristics, and ultimately have a serious impact on flight safety , such as the reduction of lift, the increase of drag, the reduction of stall angle of attack, and the separation of the boundary layer in advance. [0003] To ove...
