BASIC INFORMATION

The TV-117 turboprop engine (type certificate No. 114-D issued by the IAC Aviation register) was developed in 1997 for Il-114 regional airliners. Its cost-effectiveness, service life and reliability can rival those of the best models in this class in the world.

PRODUCT QUALITY

Innovative technologies

The most recent version of the engine (TV7-117C) features an enclosed centrifugal wheel that increases its power by 10% while maintaining all the other performance parameters. The Klimov Company holds a patent for the design and manufacturing of such wheels.

Engineering excellence

The engine has a modular design. Modules can be replaced in the field, which dramatically reduces costs and accelerates repair and maintenance.

Universal platform

The modernized TV7-117SM engine was certified in 2002 (Supplement No. 114D/04 to the type certificate No. 114-D). This version features a state-of-the art full authority digital control system (FADEC). This engine also has superb consumer qualities such as reliability, ease of maintenance and servicing.

These engines hold considerable promise as a component of new regional airliners such as Il-114, Il-112, MiG-110, Tu-136 and others.

Several versions of the TV7-117 are currently under development, including a TV7-117V turboshaft engine for new medium-load helicopters, speed boats and power generators.
