TV7-117S AIRBORNE
TURBOPROP ENGINE
The TV7-117S turboprop engine is intended to
power Il-114-type airplanes. The TV7-117S is
a modular turboprop engine with a variable-
stator axial/centrifugal compressor and a free
turbine. The engine is equipped with an elec-
tronic engine control system provided with a
hydromechanical backup subsystem.

TV3-117 AIRBORNE
TURBOSHAFT ENGINE
The TV3-117 turboshaft engine is
designed to power Mi-8MT, Mi-14,
Mi-24, Mi-28, Ka-27, Ka-28, Ka-29,
Ka-31, Ka-32, Ka-50, Ka-52 helicopters.
Structurally, the engine consists of a
variable stator 12-stage axial flow com-
pressor with guide vanes of the first four stages, a direct-flow
annular combustion chamber, a two-stage axial flow compressor
turbine, a two-stage axial flow free turbine, an exhaust duct with
flow deflection through 60°, a new electronic control and monitor-
ing system. A dust-proof device may be installed at the compres-
sor inlet.
The TV3-117 is one of the world’s best engines in its class in
terms of efficiency achieved due to high performance of its basic
components. The engine features a long service life and high
reliability. It is simple in operation and features high repairability.
Over 15 modifications were developed from the TV3-117. The
TV3-117VM/VMA (Series No. 02) versions have been certified in
Russia, CIS countries, Canada, China and India. The latest
TV3-117VMA-SB3 (VK-2500) modification boasts upgraded per-
formance characteristics.
