METHOD OF CONTROL OF HELICOPTER POSITION IN HOVERING MODE AND SYSTEM FOR REALIZATION OF THIS METHOD Russian patent published in 2005 - IPC

FIELD: control of helicopter position at low speeds and hovering.

SUBSTANCE: proposed method includes TV observation of surface under helicopter, determination of present hover height and/or present deviation from preset height making display of surface. Then bank and pitch angle data are determined and projections of longitudinal and transversal axes of helicopter are formed on indicated under-helicopter surface display in earth coordinate system and height scale image is applied with symbol of preset hover height and index indicating the present hover height and/or present deviation from preset height. In the course of control, point of intersection of axes is matched with point of preset hovering place and index on height scale is placed near preset hover height symbol. Proposed system is provided with control console, bank and pitch sensor, height sensor and/or sensor of deviation from preset height, TV camera, indicator and TV information processing unit.

EFFECT: enhanced accuracy of control of helicopter position in hovering mode due to full-scale information support both at manual and automatic control.
