Overview

HAL with its vast experience has acquired state-of-the-art technologies for manufacture, repair and overhaul of engines.

HAL manufactures Adour, Dart, Garrett and Artouste engines in addition to the engines for MiG 21 variants and MiG 27M. HAL’s Engine Divisions have specialised in the development of small gas turbines and engine test beds.

HAL provides Spares and Services support on Dart, Artouste and MiG related engines for its overseas customers.

HAL’s clientele spans across USA, Thailand, Malaysia, Nepal, Mauritius, Namibia, Sri Lanka, Vietnam and Egypt

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.

Potential For Overhaul and Repair – 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.

Rolls Royce 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.
