US 4,882,845 A · Gyroscopic artificial horizon

Abstract

A gyroscopic artificial horizon comprises a gyroscope suspended in a gimbal ount which has an inner frame and an outer frame pivoted, one within the other, about two orthogonal axes. It also comprises a device for sensing the spatial position of the axis of the gyroscope and for displaying this position in the form of an artificial horizon. To simplify the mechanical structure and to increase the reliability of the gyroscopic artificial horizon, the device for sensing and displaying the spatial position of the gyroscope axis comprises a luminous display screen rotationally coupled to the outer frame of the gimbal mount. It further comprise a sensor for sensing the angular position of the inner frame relative to the outer frame and a processor device adapted to display this angular position on the screen in the form of an artificial horizon.

Dependent claims

Gyroscopic artificial horizon comprising a gimbal mount mounted in a support structure, a gyroscope suspended in said gimbal mount, said gimbal mount having an outer frame adapted to rotate about a first axis and an inner frame adapted to rotate relative to said outer frame about a second axis orthogonal to said first axis, a luminous display screen rotationally coupled to said outer frame for displaying an angular position of said outer frame relative to said support structure, a sensor disposed either on the inner or the outer frame for sensing the angular position of said inner frame relative to said outer frame, and a processor adapted to drive said luminous display screen to show said angular position of said inner frame relative to said outer frame as an artificial horizon.
