Tray-adapted support power supply for electronic aviation equipment

摘要

Invention Patent: "SUPPORT ENERGY SUPPLY ADAPTED IN TRAY FOR ELECTRONIC AVIATION EQUIPMENT". A support power supply for electronic aviation equipment that can be installed in existing electronic aviation equipment trays without having to restart the aircraft. According to a preferred embodiment of the invention (described for illustrative purposes in the context of providing a supporting power supply for a cabin voice recorder (CVR)), the power supply / CVR combination is retrofitted on a CVR rack existing. The energy supply is, according to the preferred modality mentioned above, modular; removable / replaceable; and is "independent" with respect to the main power source and aircraft connection. The power supply / CVR combination is designed to fit into a conventional CVR tray; and the CVR is designed to fit the modular power supply. In addition, according to a preferred mode, the power supply is "plug compatible" with the electrical connector on the CVR tray and includes a circuit that allows the power supply and CVR to be tested using the test button CVR in the cab; and to report the deficiencies of each unit using existing aircraft connections. In addition, the power supply includes a circuit that automatically disconnects electrically from the CVR and the exposed pins when the power supply is removed from the CVR tray. The CVR and the power supply of the preferred modality of the invention, being modular, are easy to install, do not require cables, occupy approximately the same space previously occupied by the existing CVR, and have the same center of gravity as the existing CVR. Integrated aviation electronics / support power supply units are also considered by the invention where the units are designed to fit into existing equipment trays to eliminate and / or minimize the need to restart the aircraft.
