Background technology
Icing is a kind of physical phenomenon being widely present in flight practice, and it is the main hidden danger for causing flight safety accident
One of.When aircraft is below the freezing point in environment temperature or in flight under the conditions of the icing meteorology near freezing point, the supercooling in air
Droplets impact, can be in wing, empennage, rotor, air intake duct, windshield, antenna house, gauge sensor etc. to aircraft components surface
Icing phenomenon occurs for parts surface.Aircraft, which freezes, not only increases the weight of aircraft, and destroys the pneumatic outer of aircraft surfaces
Shape, Flow Field is changed, destroy aeroperformance, cause aircraft maximum lift to decline, flight resistance rises, under operating characteristics
Drop, stability are reduced, and very big threat is caused to flight safety.The aircraft accident triggered by icing is of common occurrence, sternly
The icing of weight even can cause fatal crass.Therefore, studied for the anti-icing of aircraft, deicing, there is important reality meaning
Justice.
