Title:
METHOD FOR CONTROLLING A HELICOPTER POSITION IN A HOVER MODE AND SYSTEM FOR CARRYING OUT SAID METHOD
Document Type and Number:
WIPO Patent Application WO/2005/078545
Kind Code:
A1
Abstract:
The group of inventions relates to methods for controlling a helicopter position in a low-speed and hovering mode above a specified point. The inventive method consists in carrying out the television tracking of a surface under the helicopter, in determining a current hovering altitude and/or a current deviation from a specified altitude and in displaying the thus obtained surface picture. Said method also consists in determining angular data obtainable on the basis of the helicopter roll and pitch, forming on the displayed picture of the surface under the helicopter the data-based image of projections of the helicopter longitudinal and transversal axes which are vertical in a earth-based co-ordinate system and pass through the centre of gravity thereof or the axes which are parallel to said longitudinal and transversal axes oriented through the elements of the helicopter structure and in plotting the picture of an altitude scale provided with a symbol of the specified hovering altitude and an index displaying the current hovering altitude and/or a current deviation therefrom. During the control, the intersecting points of the projections of the axes are superposed with the picture of a specified hovering place and the index is located on the altitude scale near the of the specified hovering altitude symbol. The inventive control system comprises a control board, a roll and pitch sensor, an altitude sensor and/or a sensor showing the deviation from the specified altitude, a TV camera and indicator unit for processing television information. Said group of inventions improves the control accuracy of the helicopter position by improved visual and full information support of a pilot during the manual and automatic control of the helicopter.
