METHOD FOR PREVENTING SPONTANEOUS ROTATION OF A HELICOPTER Russian patent published in 2022 - IPC B64C19/00 B64D43/02 B64C27/82

Abstract RU 2782038 C1

FIELD: helicopters.

SUBSTANCE: invention relates to a method for preventing spontaneous rotation of a helicopter. To prevent spontaneous rotation of the helicopter in the "flight" at low speeds and "hovering" modes, the procedure for simultaneously measuring speeds with two sensors is carried out, the inductive speed of the tail rotor is measured with the first airspeed receiver with a frequency output, the crosswind speed with a second airspeed receiver with a frequency output is measured with by turning the tail rotor, calculate the value of the ratio of the output frequency signals, compare the value of the ratio with the allowable one, give a signal to the pilot about the dangerous flight mode when the allowable value of the ratio is exceeded.

EFFECT: increased safety of helicopter flight.
