KR-12SI

KR-12SI System Overview

The KR-12SI is an aircraft ignition starting coil designed for generation of high-voltage pulses required for engine start. The unit operates as part of ignition systems of aircraft engines and auxiliary power units.

KR-12SI Ignition Function

The coil converts low-voltage onboard DC power into high-voltage pulses through an electromagnetic interrupter, ensuring reliable spark generation at ignition plugs for fuel-air mixture ignition during engine start.

KR-12SI Aircraft Application

The unit is used in ignition systems of engines and APUs such as AI-8, AI-9, and AI-9V, and is installed on aircraft and helicopters including Mi-8, Mi-24, Ka-27, Ka-32, Ka-50, Ka-52, Be-12, and An-140.

KR-12SI System Integration

The coil is installed in a shielded metallic housing to reduce electromagnetic interference and operates in conjunction with ignition plugs and high-voltage leads. The electrical configuration follows a single-wire scheme with grounding through the корпус. The product is also known under alternative designations KR-12SI and КР-12СИ.
