Abstract: The present invention relates to a rotating mechanism with lockable gear that provides safer and more functional mobility within the vehicle for the mechanisms for the display systems mechanism placed in wheeled or tracked military vehicle. The present invention particularly relates to a rotating mechanism with lockable gear comprised of a vertical axial rotating mechanism (100), which rotates display systems placed in wheeled or tracked military vehicles around the vertical axis Y, a horizontal axial rotating mechanism (200), which rotates display systems placed in wheeled or tracked military vehicles around the horizontal axis X and a locking mechanism (300), which immobilizes movement of the display systems by preventing its mobility.

Abstract: The invention relates to an easy-to-transport avionics test server for on-site (without removing from the plane) testing of IFE (In-Flight Entertainment) servers, which are components of in-flight entertainment systems, containing counterparts of all the interfaces on the IFE server, capable of generating all the signals the aircraft sends to the cabled IFE server and analyzing the responses.
