COMMAND AND FLIGHT INDICATOR OF HELICOPTER Russian patent published in 2022 - IPC G01C23/00 

FIELD: aviation.

SUBSTANCE: invention relates to devices for displaying information used by a pilot and crew members in piloting a helicopter, namely to command and flight indicators (hereinafter – CFI). Helicopter CFI contains a display, on which a reference index “Plane” stationary relatively to the center of an indication field of the display, a movable index “Leader” displayed on the display, a symbol generator connected to the display, and means for controlling the movable index “Leader”, made in the form of a unit for calculating characteristics of the “Leader” are displayed. Moreover, the unit for calculating characteristics of the “Leader” contains a unit for calculating parameters of the current sliding angle, a unit for calculating a value of a calculated roll angle, a unit for calculating a calculated sliding angle, a unit for calculating a coefficient of an aircraft flight speed, a unit for calculating aircraft deflection by the flight height and a coefficient of a deflection scale of the aircraft flight height, a unit for calculating a value of a calculated pitch angle, a unit for calculating a side deflection and a coefficient of a side deflection scale of the aircraft, to inputs of which signals from aircraft systems enter. At the same time, CFI is additionally equipped with an ADC unit, a unit for calculating an angular position of elements for controlling a number of revolutions of a shaft of a main rotor of the index “Plane”, a unit of proportions of lines and the height scale, a unit for algebraic assembly of indices.

EFFECT: increase in the safety of helicopter piloting.
