AIRCRAFT GAS TURBINE ENGINE CAPACITIVE IGNITION SYSTEM CONTROL DEVICE Russian patent published in 2022 - IPC F02P17/00 F23Q23/00 H01T13/58 F02M65/00 

FIELD: chemistry.

SUBSTANCE: invention relates to ignition of combustible mixtures using an electric spark, in particular to capacitive ignition units, and can be used to control ignition systems installed on aircraft engines. Aircraft gas turbine engine capacitive ignition system control device, comprising a storage capacitor discharge current sensor, first univibrator, time interval meter, control signal generator, in which time interval meter output is connected to control signal generator first output, circuit additionally includes an activator capacitor discharge current sensor, a second univibrator, a counter, wherein the activator capacitor discharge current sensor is connected to the activator capacitor circuit, storage capacitor discharge current sensor output is connected to the first univibrator input, the first univibrator output is connected to the time interval meter input and to the counter reset input, output of the capacitor discharge current sensor is connected to the input of the second univibrator, the output of the second univibrator is connected to the counting input of the counter, the output of the counter is connected to the second input of the control signal generator.

EFFECT: increased depth of control of technical condition of capacitive ignition systems of gas turbine engines of aircraft in order to ensure operation of spark plugs according to technical condition and reduced costs for ensuring the life cycle of the engine at the operation stage and the downtime of the aircraft by replacing the spark plugs before the onset of their failure state.
