Products in Current Manufacturing Range

 

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.

 

AL-31 FP engine

AL-31FP is a high temperature turbojet by-pass engine of modular design. 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. AL-31FP engines ensure stable operation in all available evolutions of the aircraft in super maneuverability modes. AL-31FP engines power advanced multi-purpose Su-30 MKI  fighters of the 4+ generation
 

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.
