Engine Division, Koraput was established in the year 2004 to manufacture AL31FP Engines engines for fitment in Su-30MKI Aircraft under Licence from Russia. In 2007-08 facilities were established for overhauling of AL31FP Engines under licence from Russia.
Over last five decades, Division has manufactured more than 350 engines and overhauled more than 300 Aero Engines with an aim to ensure maximum aircrafts flying.
AL31FP Manufacturing & Overhaul Project
Progress of manufacturing and overhaul works is reviewed through latest IT enabled systems ensures timely completion of assemblies and sub-assemblies of the engines. The stripped components are subject to stringent quality checks using modern technology like CMM, NDT and other non-contact measurements. Manufacturing, Repair and refurbishing of worn-out parts and sub-assemblies are undertaken by skilled workmen. Division is also manufacturing most of the components in-house, which are required during overhaul. 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, sub-assemblies and Engine accessories 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. 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 computerized controls. Electronically assisted throttle, digital and analog read-outs help get real-time simultaneous data and engine parameters during Engine testing.

Rotables
In addition to Engine IAF gives us additional task to overhaul Rotables. There are more than30 types of Rotables which are being overhauled in-house. All these Rotables undergo vigorous Quality checks and testing procedure before being released to bases for exploitation.
Supply of Spares and other major units
The Division manufactures and supplies the entire range of spares required for first and second-line servicing of engines at the IAF bases and base repair depots.
Site Repair
The Division undertakes site repair of Engines at the IAF bases by deputing site repair teams regularly.
Defect Investigation/Failure Analysis
The Engines / Aggregates which are received due to premature withdrawal from the units are studied and the causes for defects/failures are investigated. After proper analysis and deliberation, corrective action is taken to minimize the recurrence of defects in future.
Workshops
The Division conducts workshops regularly to the customers at Koraput in specialized areas for better understanding and utilization of the products.
Positioning of Service Engineers
The Division has posted Service Engineers at various IAF bases to closely liaise and assess the requirement of the customers. Based on the feed-back received from these Service Engineers, the Division renders adequate support for fully utilizing the products.
