Jaguar aircraft is powered by two Adour Mk804 / Mk811 engines. Adour Mk 811Enignes were manufactured since 1981 under licence from M/s. Rolls Royce/ Turbomeca. Presently, these engines are being Repaired & Overhauled.

Features:
• Twin spool turbofan engine of modular construction with after burner.
• 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.

TM333 2B2 / TM333 2M2 Turbo shaft engine powers ALH MK I, II & Cheetal Helicopter respectively. These engines are repaired / overhauled under license from M/s. Turbomeca, France.

• Modular construction with annular air intake, two stage axial compressor together with a centrifugal compressor driven by a single stage turbine.
• Annular reverse flow combustion chamber.
• Single stage free turbine with a through shaft driving a reduction gear unit.
• Full authority digital engine control. (FADEC).
• Simple installation and easy access for maintenance.
• Low specific fuel consumption.

ALH MKIII (Dhruv)/Mk IV (Rudra –WSI)/LCH

To meet high altitude operational requirement and additional payload capacity, an engine with higher power than TM333-2B2 was required for certain variants of Dhruv. Turbomeca and HA L co-developed an engine named Shakti 1H1 (Ardiden) which meets the above requirements.

•  Turbo shaft engine with an annular air intake
•  Two-stage centrifugal compressor driven by a single-stage gas generator turbine
•  Reverse flow combustion chamber
•  Two-stage free power turbine with a through shaft driving the reduction gear box unit
•  Dual channel FADEC (Full Authority Digital Engine Control)

HAL’s responsibilities included rotor dynamic analysis, casing design, static parts stress analysis, HMU system design and electrical harness system. Additionally HAL was responsible for the design, development, certification and manufacture of the oil cooling system, oil pump, filter unit assembly pipelines and brackets. Shakti Engine also powers LCH (Light Combat Helicopter).

Artouste IIIB Engine powers both Cheetah and Chetak helicopters. The Engine manufacture commenced in 1962 under licence from Turbomeca, France.  Division also has facility for Repair & Overhaul of these engines.

Features:

• Side air intake, an axial and a centrifugal compressor connected to three stage turbine.
• The power output is 543 SHP at 33500 RPM. The reduction gear box in the front transfers the power to helicopter.
• More than 700 engines have been manufactured and 3500 engines overhauled & repaired for various customers.

The Garrett TPE 331-5 turbo prop Engine is being manufactured, overhauled and repaired for various customers under licence from Honeywell USA, since 1988. It belongs to one of the most popular series of small turbo prop engines powering a large number of commuter and corporate aircraft such as commercial aircraft. The division has also manufactured kits for Garrett TPE 331-12 under collaboration from Honeywell for international markets.

 Features:

• Single shaft centrifugal compressor engine rated at 715 shaft horse power at 1591 RPM output speed.
• Reverse flow gas turbine with a small frontal area
• Features a propeller control system, anti-icing and foreign object damage resistance
• Reverse thrust and negative torque sensing facilities

The Dart series of engines were manufactured since 1966 under licence from Rolls Royce, UK. Presently, these engines are being repaired. 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.

Orpheus 70105 , indigenously modified by HAL, is a derivative of Orpheus 701 at lower rating and is the power plant for Kiran MK II aircraft. The engines were earlier manufactured and presently being repaired at the division.

The Gnome 1400-IT engines are being repaired and overhauled under licence from Rolls Royce, UK and is the power plant for Seaking helicopter. It is a turbo shaft single spool with 10 stage axial compressor, two stage turbine and free power turbine.

The Jet Fuel Starter (JFS) for starting the main engine of Light Combat Aircraft (LCA) is a twin shaft gas turbine consisting of a centrifugal compressor driven by an axial turbine, reverse flow combustor, digital electronic fuel control system and a free power turbine that supplies the motive power for starting the LCA engine.

Aircraft Mounted Accessory Gear Box (AMAGB) is a single input, multiple output gear box, which takes its input drive from the TEJAS ENGINE through a Power Take-Off (PTO) shaft at rated speed of 16,810 rpm. It carries four aircraft accessories on its output pads viz., two hydraulic pumps, one generator and one starter unit. Together these cater to major part of hydraulic & electrical power requirements of the aircraft and hence form a crucial part of the Secondary Power System.

Designed and developmed to power the Pilotless Target Aircraft, LAKSHYA. This engine is a single shaft, Light weight, low cost turbojet engine, which is remotely controlled during flight.
Features:

• 4-stage axil compressor driven by an axial turbine, annular combustor, and power control unit.
• Digital electronic fuel control system
• Develops 380 kg thrust

Can be refurbished after land/sea recovery
