ELECTRIC IMPULSE DE-ICING DEVICE Russian patent published in 2014 - IPC B64D15/00 

FIELD: electricity.

SUBSTANCE: electric impulse de-icing device is related to impulse devices and may be used for mechanic de-icing of metal coating of vehicles such as planes, helicopters, aerofoil boats and vessels. It comprises electromagnetic induction coils, a control pulse distributer and an ice detector. The electromagnetic induction coils are coupled through thyristors in parallel to a storage capacitor connected to a charger. The control pulse distributer comprises in-series clock generator, a pulse counter and a decoder. The clock generator is frequency controlled; it includes the master clock, a three-digit binary counter, a multiplexor, and three comparators. The decoder outputs are connected through pulse amplifiers to control electrodes of the thyristors. The ice detector output is coupled to the controlled input of the clock generator. The device ensures partial load modes of force impact during pulse treatment of the de-iced coating.

EFFECT: reducing probability of coatings damage, reducing consumed power of the device and increasing its service life.
