SKNA-22-2A

SKNA-22-2A System Overview

The SKNA-22-2A is an aircraft ignition unit designed to convert onboard power supply voltage into the required voltage for operation of semiconductor spark plugs within gas turbine engine ignition systems.

SKNA-22-2A Control Function

The unit generates high-voltage pulses and ensures stable discharge across semiconductor surface-discharge spark plugs, enabling reliable ignition of the fuel-air mixture during engine start in both ground and flight conditions.

SKNA-22-2A Aircraft Application

The unit is used in ignition systems of gas turbine engines equipped with semiconductor spark plugs and is installed on aircraft where reliable ignition performance is required under varying operational conditions.

SKNA-22-2A System Integration

The unit operates in conjunction with ignition plugs, wiring assemblies, and onboard electrical systems, utilizing internal components such as induction coils, rectifiers, capacitors, and discharge elements housed within a metal enclosure. The product is also known under alternative designation SKNA-22-2A.
