SK-22-2K

SK-22-2K System Overview

The SK-22-2K is an aircraft ignition unit designed as part of gas turbine engine ignition systems, providing high-voltage energy required for ignition of the fuel-air mixture within the combustion chamber.

SK-22-2K Control Function

The unit converts low-voltage onboard DC power into high-voltage pulses supplied to ignition plugs, ensuring reliable spark generation and stable ignition during engine start and operation.

SK-22-2K Aircraft Application

The unit is used in ignition systems of turboshaft engines such as the TV3-117 and is installed on helicopters including Mi-8 family (Mi-17, Mi-171, Mi-172) and Ka-32.

SK-22-2K System Integration

The unit operates in conjunction with ignition system components and onboard electrical systems, providing energy accumulation and discharge in a controlled sequence. The product is also known under alternative designation SK-22-2K and СК-22-2К.
