HAL Hands Over the 50th Raw Material Phase Engine of Su-30MKI to IAF
Bengaluru/Delhi, October 24, 2017:
The 50th AL31FP engine, manufactured from raw materials by Sukhoi Engine Division of HAL (Koraput) has been handed over to IAF in Delhi yesterday as part of celebrations of 70th year of India Russia diplomatic relationship.
“The AL31FP engine powers Su30 MKI and is manufactured from raw material stage. All the components, including heavy forgings are manufactured at HAL”, said Mr. T. Suvarna Raju, CMD, HAL. He handed over the documents related to the 50th Raw Material Phase Engine of Su-30MKI to Air Marshal S.B. Deo, VCAS.
A Coffee Table Book was also released on this occasion by Mr. A. K. Gupta, Secretary (DP) to commemorate 70 years of cooperation between HAL and Russian companies to protect the Indian sky. Speaking on the occasion Mr. Gupta pointed out the whole hearted support India has been receiving for the Russian platforms and said such a support is important in strengthening the bilateral ties.
About HAL Koraput:
The engine division is ensconced in the valleys of Koraput region in Orissa. It was set up to manufacture turbojet engines for the MiG 21FL. The first assignment taken up by the Division was to manufacture R11-F2 turbojet engine for MiG 21FL aircraft. Subsequently, the Division took up manufacturing of R11 series engines of MiG 21FL and MiG 21M aircraft, R25 series engines of MiG 21BIS aircraft, R29B engines for MiG27M aircraft and RD33 series engines for MiG29 aircraft. The Division is currently engaged in the overhaul of R25, R29B and RD33 engines. In 2004 the Sukhoi Engine Division was established and it has started manufacturing and subsequently overhauling of AL31FP engines for SU30MKI aircraft. Till date the Division has manufactured nearly 1675 engines and overhauled 7730 engines, which includes R11, R25, R29B, RD33 and AL31FP engines.
About AL31FP Engine:
It is a twin spool, axial flow, low bypass turbo fan engine incorporating After Burner System, variable area Jet Nozzle with thrust vectoring, air-to-air heat exchanger, anti-surge system. A specific feature of AL-31FP is an axi-symmetric vectoring nozzle with a thrust vector angle of ±15° in the vertical plane providing super maneuverability of the aircraft. The vectoring nozzle control is integrated with the engine control system. The AL-31FP engines ensure stable operation in all available evolutions of the aircraft in super maneuverability modes. Till date 357 engines are manufactured which includes engines of phase I to phase V.

AL 31 FP
The Engine Division at Koraput, a unit of HAL's vast network, has the unique distinction of being one amongst the few Aero Engine manufacturers in the world.
The spectrum of manufacturing facilities extends literally from the production of nuts and bolts to discs, shafts, blades, forgings and castings - all that are required to make an Aero Engine right from the Raw materials.
This spectrum is further enlarged to include overhaul of Aero Engines for the MiG family and supply of spares required during service
R25 engine
This is a Twin Spool, Axial Flow, Turbojet Engine fitted with After burner and a variable area Jet nozzle. It powers the MiG-21 BiS multi-role Fighter Aircraft. The Engine has provision for an emergency After-burner thrust boost, which can be selected below 4.5 KM altitude.
R-29B engine
This Engine is a Twin spool, Axial flow Turbojet Engine incorporating After-burner system and variable area Jet nozzle of convergent-divergent type. The Engine is equipped with automatic Fuel regulation system, Turbo-starter, Anti-surge system, Temperature controller, Constant speed drive for AC Generator and Two speed drive for Hydraulic Pump. R-29B Engine powers MiG-27 M, a Multi-role Ground attack / Air combat Aircraft.
Precision Components
Division also produces precision components like: total gamut of Blades ranging from Compressor Rotors and Stators to Turbine Blades and Nozzle Guide Vanes, intricate Cored Magnesium Alloy Gear Casings, Compressor and Turbine Discs and Shafts, JIS class-l/DlN 5 Spur, Helical Gears and DIN 6 straight and Hypoid / Spiral Bevel Gears ranging from module 1 to 6.

Manufacturing of New AL31FP Engines and Overhaul of AL31FP Engine & its aggregates, Supply of Spares.
The stripped components are subject to detailed micrometric and Non Destructive Testing (NDT) checks. Repair and refurbishing of worn-out parts and sub-assemblies are undertaken by skilled workmen.
Manufacturing, Repairs and Refurbishing Processes include machining, welding, hard alloy coatings, vibro-tumbling, micro-shot peening, ultrasonic strain hardening, nickel alloy powder coating and a large number of protective coatings. Assemblies and sub-assemblies undergo rigorous functional tests on various Hydraulic, Fuel and Electrical Rigs.
Quality control checks are carried out using various NDT methods, like X-ray, Magna-flux, Dye-penetrant check and ultrasonic inspection besides other conventional techniques. Overhaul of accessories is carried out in environmentally controlled rooms. All the accessories after overhaul are subjected to stringent tests on test rigs.
Every manufactured / overhauled Engine undergoes rigorous tests on Engine test beds that simulate all flight conditions.
The preliminary and final acceptance test, hot test, endurance test and gas dynamic stability tests are conducted through computerised controls.
Electronically assisted throttle, digital and analog read-outs help get real-time simultaneous data and engine parameters during AL31FP Engine testing. Repairs, Major Servicing, Supply of Spares
Since the early 1970's, the Division has been overhauling Aero Engines to make fighter Aircraft flight-worthy again for the Indian Air Force.
The Division follows the 'Flow Line Group Technology' with the Engine parts being dismantled, viewed and loaded to different work centres.
Regular follow-up through PC ensures timely completion of sub-assemblies.
