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.

±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
