BASIC INFORMATION

BARK automatic control and monitoring units are designed to be used as a component of gas turbine power plants installed, in particular, on helicopters, aircraft and boats.  Based on the FADEC concept, these units incorporate the latest breakthroughs in technology.

The Klimov Company’s research centre and special manufacturing facility deal with the development, production and servicing of BARK electronic units for all types of existing and prospective engines.

PRODUCT QUALITY

The BARK units:

• extend the service life of the hot parts of the engine;
• improve the gas flow stability margin of the engine running in variable modes and during aircraft maneuvering;
• improve the accuracy and quality of engine control;
• adapt engine control to the ambient situation;
• compensate for the response time of gauges that measure controlled and monitored parameters;
• provide deep engine control to ensure condition-based operation;
• significantly reduce the weight and volume of electronic components of the system as well as connecting cables.

МОДИФИКАЦИИ
