SYSTEM OF PROTECTION OF OBJECT SURFACE FROM ICE FORMATION Russian patent published in 2008 - IPC B64D15/16 

FIELD: protective means.

SUBSTANCE: invention refers to protection of object surfaces from ice formation and can be used on aircraft for ice formations removal. The system of protection contains inductors assembled under protected from ice formation surface of a coat; the said inductors are connected to impulse distributing units. These units are connected to a unit generating high voltage impulses; the latter is electrically tied with an output of a thickness indicator unit. The total thickness of the coat and a current conducting screen installed between the coat and the inductor must be not less, than a depth of penetration of electromagnetic field which is generated with an inductor coil. The current conducting screen with a diameter equal to a diameter of a working surface of the inductor is fixed rigidly to the coat via a flexible component placed between them; a diameter of the said component is equal to a diameter of the screen. The inductor is assembled against the screen with a gap of 0.1-0.2 mm.

EFFECT: increased efficiency of ice removal and maintaining necessary resource of an object frame at reduced weight of the system due to increased simultaneous protection of coat surface area from ice formation.
