Ice preventing and removing device for helicopter rotors

Abstract

The invention discloses an ice preventing and removing device for helicopter rotors. The device comprises an icing detector, an icing speed solver, an atmospheric temperature sensor, an ice preventing and removing control panel, a digital type ice preventing and removing controller, a main rotor distributor, an empennage distributor, a main rotor ice removing component, an empennage ice removing component, an No.1 AC power supply and an No.2 AC power supply, wherein the icing detector and the icing speed solver transfer liquid water content signals and atmospheric temperature signals to the digital type ice preventing and removing controller respectively, the digital type ice preventing and removing controller carries out computation according to the ice preventing and removing control panel and the input signals to output the control signals of the main rotor distributor and the control signals of the empennage distributor, and the main rotor distributor and the empennage distributor control the main rotor ice removing component and the empennage ice removing component to remove ice. By the ice preventing and removing device, the helicopter can safely fly under server weather conditions, and the safety accidents due to the icing of the rotors and the bad influence of pneumatic configuration caused by too low ambient temperature or too high water content are avoided.

Description

technical field [0001] The invention relates to a helicopter rotor anti-icing device, which belongs to the technical field of helicopter safety protection. Background technique [0002] The flying altitude of helicopters is mostly below 6000m. In this altitude range, severe weather such as rain, snow and ice are often encountered, and the liquid water content in the atmosphere is also high, which will cause the helicopter to encounter the danger of icing during missions. The rotor of the helicopter is not only the lift component, but also bears the main functions such as manipulation. The icing on the surface of the blade will directly threaten the safety of the helicopter, and protective measures must be taken for it. See: Fu Jianping. Helicopter Anti-icing Technology Research. Flight Mechanics, 2005 and Wang Zongyan. Helicopter anti-icing problem. Helicopter Technology, 2001. [0003] In order to prevent the serious impact of rotor blade icing, there are two measures: one...
