Artificial Icing Test Ice Phobic Coatings on UH-1H Helicopter Rotor Blades.

摘要

The United States Army Aviation Engineering Flight Activity conducted a limited evaluation of the General Electric G697 compound and the Dow Corning E2460-40-1 substance to determine if either was useful as an ice phobic coating on UH-1H helicopter rotor blades. Testing was conducted at Spokane, Washington, from 9 January through 8 February 1978. During the tests 23.2 flight hours were accumulated of which 6.5 hours were in the icing environment. Within the scope of this test both and G697 and the E2460-40-1 aided in shedding ice accreted on the main rotor blades.
