FIELD: aircraft gas-turbine engines.
SUBSTANCE: invention relates to device for lighting up combustion chambers of aircraft gas-turbine engine and it can be used also in ignition systems of stationary gas-turbine plants or other electrical equipment enclosed in sealed shell. Proposed capacitive set contains sealed shell and electric elements. Sealed shell is formed by housing provided with supply connector and high-voltage terminal and cover hermetically connected with housing. Electric circuit elements are installed on bottom of housing in hardened foam plastic filling free space between elements. Gaseous medium inside shell of set is under pressure lower than pressure of atmospheric air.
EFFECT: increased heat resistance of capacitive ignition sets at preservation of higher vibration strength.
