Problems solved by technology
For example, icing on the upper surface of the wing will directly lead to the deterioration of the aerodynamic performance of the aircraft. The increase in weight and the destruction of the aerodynamic shape reduce the safety and maneuverability of the aircraft. It is attached to the surface of the wing and has a large roughness. The frost layer can change the surrounding flow field and destroy the aerodynamic performance, which can cause the maximum lift to decrease by 32%, and the drag to increase by 40%. posed a great threat

An anti-icing device and an anti-icing control method based on the device, comprising an anti-icing film, an ice layer thickness detection unit and a control unit, the anti-icing film includes a flexible base, an electrothermal material layer and a piezoelectric material layer, the electrothermal The material layer and the piezoelectric material layer are arranged on the flexible substrate, and the ice layer thickness detection unit detects the degree of icing on the anti-icing film, and transmits the degree of icing to the control unit, and the control unit According to different icing degrees, at least one of the electrothermal material layer and the piezoelectric material layer is controlled to perform anti-icing operation. The anti-icing device can better prevent the generation of the ice layer, and can better remove the ice layer after the ice layer is generated.
Description
technical field [0001] The invention relates to the field of anti-icing, in particular to an anti-icing device and an anti-icing control method based on the anti-icing device. Background technique [0002] Icing is a very common weather phenomenon. It refers to the process in which liquids such as water vapor accumulate and solidify on the surface of objects in a low-temperature environment to form a solid ice layer. This physical phenomenon that is usually common to people has produced a major safety hazard to daily transportation and life security. [0003] Airplanes, for example, suffer from icing. We know that the daily flight altitude of civil aviation airliners or military aircraft is above 6,000 meters, and may even reach above 10,000 meters. In this high-altitude environment, the ambient temperature is usually above minus 30 degrees, which is far lower than the freezing point of water vapor at 0 degrees. A layer of ice forms on its surface. The formation of this...
