PROTECTIVE SHIELD AGAINST IMPACTS OF ICE ON AIRCRAFT Russian patent published in 2017 - IPC B64C7/00 B64C5/00 B29C73/16 B29C73/22 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to aircraft engineering, particularly to a self-recovering shield protection against impacts of ice on an aircraft (AC), in particular, an AC with propeller engines. Protective shield against impacts of ice on an aircraft structures comprises layers of a composite material (CM) having microcapsules containing a recovering agent. Herewith the CM also contains microcapsules containing particles of a catalyst. Under action of the catalyst particles the recovering agent becomes a polymerized recovering agent, where the recovering agent is dicyclopentadiene. Herewith the catalyst particles are particles of tungsten hexachloride and diethylaluminium chloride (WCl₆-Et₂AlCl).

EFFECT: provided is higher flight safety due to the use of a self-recovering material, which recovers the protective material in flight.
