METHOD OF MAINTENANCE OF NUMBER OF REVOLUTIONS OF HELICOPTER LIFTING ROTOR WITHIN PERMISSIBLE LIMITS AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2004 - IPC

Abstract RU 2231479 C2

FIELD: aviation; helicopter control systems.

SUBSTANCE: proposed method consists in automatic change of power through change of delivery of fuel to engine (engines), check of revolutions against indicator and control of helicopter power which is performed by change of lifting rotor pitch with the aid of lever and control stick; in addition to change of collective pitch performed by pilot, automatic change of collective pitch is introduced. Device proposed for realization of this method includes collective pitch lever and control stick. Besides that, provision is made for computer whose input is connected with tacho-generator and rotor speed readjustment switch; its output is connected with converter converting electric signal to mechanical motion; it is connected with lifting rotor in collective pitch channel.

EFFECT: automatic maintenance of revolutions.
