BLADE FOR AIRCRAFT MADE WITH POSSIBILITY OF HANGING AND METHOD FOR REMOVAL OF ICE FROM SPECIFIED BLADE Russian patent published in 2022 - IPC B64D15/12 B64D15/16 B64C27/473 

FIELD: aviation.

SUBSTANCE: invention relates to a blade and removal of ice from a blade for an aircraft. Blade (7) for a propeller of an aircraft made with the possibility of hanging contains main case (11) with first outer surface (9) and anti-icing system (10) for removal of ice. Anti-icing system (10) contains first layer (20) formed by material with shape memory, activated so that to change its shape according to a value related to a temperature, which is located on at least one outer surface (9) of main case (11), and second layer (25), which forms at least section (26) of second outer surface (12) of blade (7), on which ice (13) settles. Second layer (25) laid on top of first layer (20), on an opposite side of main case, is made with the possibility of selective movement under the action of first layer (20) so that to exert mechanical impact on ice (13) and remove it from blade (7), and is made with the possibility of protection of first layer (20) from external agents.

EFFECT: increase in safety of an aircraft is achieved.
