FLIGHT DIRECTOR INDICATOR OF A HELICOPTER Russian patent published in 2022 - IPC G01C23/00 B64D45/00 B64C27/00 

FIELD: aircraft.

SUBSTANCE: flight detector indicator of a helicopter comprises a screen configured to display the indexes "Plane", "Leader", "Radio Altitude" in a particular way, as well as a metering unit for the in-flight consumption of the helicopter payload mass; a unit indicating the helicopter flight speed with a numerical scale; an index of the current helicopter flight speed indicator; an index of set helicopter flight speed indicator; a unit for calculating the spatial position of the centre of mass, the moments of inertia of the helicopter in flight, and the value of the parameter of the longitudinal distance from the centre of mass of the helicopter to the rotor axis in the coordinate system associated with the helicopter; a unit for calculating the predicted flight speed of the helicopter; and a switch of the autopilot units for the functions of automatic stabilisation by pitch, altitude and speed.

EFFECT: manual piloting of the helicopter in a vertical descending manoeuvre of a coaxial helicopter is facilitated, psychophysiological and nervous load of the pilot in the process of retaining the helicopter in the set parameters of flight is reduced, flight safety is improved due to the reduction in the load associated with the observation of flight navigation data.
