COVER UNIT OF THE AIRCRAFT VISUAL OPTICAL SYSTEM Russian patent published in 2017 - IPC B64G1/52 

FIELD: aviation.

SUBSTANCE: unit includes the cover, provided with the electric drive with the output shaft. One end of the shaft is kinematically rigidly connected to the cover by means of two mating gear half couplings with even and odd number of teeth. The adapter is provided between the half couplings, the number of teeth of which from the half coupling side interacting with it is equal to the number of teeth of this half coupling. The half coupling with the odd number of teeth is made with ability of axial movement relatively to the output shaft, while the preflight training of the cover unit is carried out. The half coupling with the even number of teeth is rigidly attached to the cover. The other end of the electric drive shaft is connected with the cover by means of the split bushing. The inner diameter of this bushing, while loosening the clamp, is more than the shaft output end outer diameter.

EFFECT: simplification of the preflight training of the mentioned cover unit by eliminating the equipment for its weightlessness.
