KV-112

KV-112 is an aircraft ignition unit designed to generate high-voltage ignition energy for initiating combustion of a fuel-air mixture in aircraft heating systems. The unit is primarily used as part of kerosene heaters, including the KO-50 heater installed on helicopters of the Mi-8 / Mi-17 family and similar aircraft platforms.

The ignition unit operates from the aircraft 27 V DC power supply and is manufactured with a two-wire power system. Power is supplied from the onboard battery, with parallel connection to a generator permitted in accordance with the aircraft electrical system configuration. KV-112 provides reliable high-voltage output to the ignition spark plug during heater start-up, ensuring stable ignition of the fuel-air mixture under specified operating conditions.

KV-112 is installed in the heater compartment and functions as an integral element of the ignition system together with the ignition spark plug. The unit is designed for continuous operation within the limits defined by the technical documentation and maintains stable performance throughout its assigned service life.

Due to its compact design and relatively low weight, KV-112 is suitable for installation in aircraft heating systems with strict requirements for reliability and electrical compatibility. The unit is supplied with a manufacturer’s passport and is typically delivered as part of heater assemblies or as a separate spare component for maintenance and overhaul of aircraft heating equipment.
