ADOUR MK 811
Jaguar aircraft is powered by two Adour MK 804 / MK 811 engines.
MK 811 engines are manufactured since 1981 under licence from
RR/TM [ Rolls Royce Turbomeca ].
Adour MK 804 engines are also overhauled and repaired under the
above licence.
Adour engine is a bypass jet engine of modular construction.
The Adour has two-stage low pressure and five-stage high pressure
axial flow compressors which are driven by separate, single-stage
high pressure and low pressure turbines connected through co-axial
shafts, with the low pressure shaft passing through the high pressure
shaft.

GARRETT 331 - 5
The Garrett TPE 331-5 turbo prop engine is being manufactured,
overhauled and repaired for various customers under licence from
Garrett Engine Division of Honey Well Company [earlier Allied
Signal Aerospace Company, USA] since 1988 and belongs to one of
the most popular series of small turbo prop engines powering a
large number of commuter and corporate aircraft such as Dornier
DO-228.
It has a single shaft centrifugal compressor engine rated at
715 shaft horse power at 1591 RPM output speed. Being a reverse
flow gas turbine with a small frontal area, it has better dry specifics
and easier airframe integration. Apart from its simplicity of
design and superior performance, the engine features a propeller
control system, anti-icing and foreign object damage resistance,
reverse thrust and negative torque sensing facilities.

Artouste III
B
 Artouste
III B Engine powers both Cheetah and Chetak helicopters. The
manufacture of this engine commenced in 1962 under licence from Turbomeca, France.
The engine has side air intake,
one axial and one centrifugal compressor connected to a three-stage turbine. The power output is 550 SHP at 33500 RPM. The reduction
gear box in the front transfers the power to helicopter. More
than 665 engines have been manufactured and 2950 engines overhauled
and repaired for various customers.

DART 533 - 2 AND 536 - 2T
 The
Dart series of engines were manufactured since 1966. under licence
from Rolls Royce, UK but at present are being repaired and overhauled.
Two Dart engines power HS-748 aircraft.
This engine has two-stage centrifugal compressors, three- stage
turbine and utilises water methanol injection to increase the
shaft horse power.

Allison 501 K – Industrial Marine Gas Turbine |
|
 The
Allison 501 K engine is derived from the T 56 Turboprop engine.
The 501 K engine is available in both single-shaft / cold end drive
and two-shaft / hot end drive configurations. Both use a common high
efficiency compressor design. The engine with the output at the
cold end is being used as a prime mover in electric generator sets.
The engine with output at the hot end is being used primarily as a
power source for pumps, compressors and other mechanical drive requirement.
The 501K engines operate on gasoline,
kerosene, diesel and natural gas.
