METHOD OF PROVIDING THERMAL REGIME OF INSTRUMENT COMPARTMENT OF AIRCRAFT Russian patent published in 2014 - IPC B64C30/00 B64G1/50 

FIELD: aviation.

SUBSTANCE: method consists in cooling the on-board equipment with the circulating gas with the help of dual-circuit cooling system. At that, the gas is cooled in the evaporation circuit due to evaporation of low-boiling refrigerant which vapours are discharged into the atmosphere. At the beginning of the flight cooling the equipment of the instrument compartment is carried out only by ventilation for the time defined depending on the temperature, heat release and heat capacity of the equipment. Then the said evaporation circuit is activated, and the low-boiling refrigerant vapours are discharged into the atmosphere through the sealing element in the form of a diaphragm valve. This valve is depressurised at a pressure of saturated vapours of refrigerant boiling.

EFFECT: improvement of thermal stabilisation of the on-board equipment, reduction of weight and increasing the reliability of the cooling system.
