DEVICE FOR MAINTENANCE OF TEMPERATURE IN AIRCRAFT AVIONICS COMPARTMENT Russian patent published in 2023 - IPC B64D13/08 B64C1/40 

FIELD: aircraft avionics.

SUBSTANCE: invention relates to devices for maintaining temperature in aircraft avionics compartment. The device is made in the form of a tarpaulin pipe with docking magnetic valves in the end parts, made with the possibility of attaching the device to the hatches of the avionics compartment in the lower part of the fuselage. The inner surface of the tarpaulin pipe is covered with a thermal insulation coating. A central ring is mounted in the central part of the pipe, on the outer surface of which a thermostat is placed, and on the inner surface thermostat heaters are mounted, made in the form of heating rods converging towards the center. A temperature sensor is placed on the heating rod. A stand is mounted in the lower part of the central ring, which is made with the possibility of installing the device on a flat surface. At the same time, the power supply of the device is carried out from the technical network of the airport.

EFFECT: preservation of the airworthiness of digital aircraft during long-term parking in conditions of extremely low temperatures is achieved.
