Icing not only increases the weight of the airplane, but also destroys the aerodynamic appearance of the surface of the airplane, changes a turbulent flow field, destroys aerodynamic performance, causes the maximum lift force of the airplane to be reduced, the flight resistance to be increased, the operating performance to be reduced and the stability to be reduced, and causes great threat to flight safety, and flight accidents caused by icing are frequent, and severe icing can even lead to the death of the airplane.
The technology of aircraft anti-icing and de-icing has long been an important research topic for aircraft system design. At present, systems such as thermal deicing, mechanical deicing, pneumatic belt deicing and the like are commonly used. Although the systems are mature in development, use and maintenance, the systems are still insufficient in energy consumption, weight and reliability, for example, the common hot gas anti-icing system has a complex structure, high energy consumption and heavy weight; the mechanical deicing system is a deicing device which removes ice on the surface by the action of mechanical force; the pneumatic belt deicing system is characterized in that compressed air is filled into the expansion pipe to expand the expansion pipe, so that a surface ice layer is broken and falls off to achieve the aim of deicing. Therefore, it is desirable to design a deicing system that is relatively simple in construction, light in weight, and consumes little energy.
