  3.   Hindustan Aeronautics Limited

Hindustan Aeronautics Limited

The Company had built aircraft and engines of foreign design under licence, such as Prentice, Vampire and Gnat aircraft. It also undertook the design and development of aircraft indigenously. In August 1951, the HT-2 Trainer aircraft, designed and produced by the company under the able leadership of Dr. V.M.Ghatge flew for the first time. Nearly 200 Trainers were manufactured and supplied to the Indian Air Force and other customers. With the gradual building up of its design capability, the company successfully designed and developed four other aircraft i.e. two seater 'Pushpak' suitable for flying clubs,  'Krishak' for Air Observatory Post(AOP) role, HF-24 Jet Fighter '(Marut)' and the HJT-16 Basic Jet Trainer '(Kiran)'.
Meanwhile, in August 1963, Aeronautics India Limited (AIL) was incorporated as a Company wholly owned by the Government of India to undertake the manufacture of   the   MiG-21 aircraft under licence. In June 1964, the Aircraft Manufacturing Depot which was set up in 1960 as an Air Force unit to produce the Airframe for the HS-748 transport aircraft was transferred to AIL. Soon thereafter, the Government decided to amalgamate Hindustan Aircraft Limited, with AIL so as to conserve resources in the field of aviation where the technical talent in the country was limited and to enable the activities of all the aircraft manufacturing units to be planned and co-ordinated in the most efficient and economical manner.
Amalgamation of the two companies i.e. Hindustan Aircraft Limited and Aeronautics India Limited was brought about on 1st Oct 1964 by an Amalgamation order issued by the Government of India and the Company after the amalgamation was named as "Hindustan Aeronautics Limited (HAL)" with its principal business being design, development, manufacture, repair and overhaul of aircraft, helicopter, engines and related systems like avionics, instruments and accessories.
In 1970, a separate division was set up exclusively for manufacture of 'Chetak' and 'Cheetah' Helicopters in Bangalore under licence from M/s SNIAS, France. A new division was also established to manufacture aircraft instruments and accessories at Lucknow. Licence agreements were entered into with M/s Dunlop of U.K. for Wheels and Brakes, Dowty for under carriages and Hydraulic equipment, and Normal air Garret for cabin air pressurisation and air-conditioning equipment, Smiths of UK, SFENA and SFIM of France for panel instruments and Gyros, Martin Baker of UK for ejection seats and Lucas for engine fuel systems, for fitment on Marut, Kiran, Ajeet, Chetak, Cheetah and Jaguar. Similar type of arrangements was agreed with USSR authorities for manufacture of accessories for MiG-21 series of aircraft.
Design and Development of Basant agricultural aircraft was undertaken between 1970 and 1974 and design and development of Ajeet, an improved version of Gnat was undertaken between 1972 and 1980. In 1976 projects were sanctioned for design & development of the HPT-32 elementary piston engine trainer, Kiran MK II (an improved version of Kiran MK I / IA) and Ajeet Trainer as well as for Advanced Light Helicopter.  
 In 1971, Avionics Design Bureau at Hyderabad was formed for the development and manufacture of IFF, UHF, HF, Radio components, Radio Altimeter, Ground Radars etc.,


HAL is actively engaged and is contributing to the space programmes of the country. A separate Aerospace division was established in 1988.  This Division is dedicated to space programme to meet the growing requirement of Indian Space Research Organisation.
In order to capture the growing market in the industrial gas turbine engines, a new Division called the Industrial & Marine Gas Turbine Division, was formed in 1998. Currently the Division is undertaking Repair and Overhaul work related with Industrial Avon Engines and Allison 501K and 571K series. In addition to this manufacture of LM 2500 engine is also being undertaken. The Division is doing the overhaul of various existing gas turbines in the country, thus providing cost-effective services to users such as ONGC, GAIL, TNEB, RSEB etc., for upkeep of their gas turbine.
An independent profit centre for providing Airport related services was created in May 2000 with a view to synergize the operation of HAL Bangalore Airport. The main aim of creation of this Airport Service Centre is to restructure the existing resources to provide focused attention in relation with the exacting market needs of service segment related to airlines operations and commercially exploit the available infrastructure of the Company at Bengaluru.
 With the signing of agreement with Russian partners to take up licence manufacture of SUKHOI 30 MKI Aircraft  the Nasik Division which had been engaged in manufacture & overhaul of MiG series Aircraft and lately upgrade of MiGB is aircraft, had to be expanded. Accordingly it was decided in February, 2002 to have two Divisions at Nasik i.e. Aircraft Manufacturing Division for Su-30 MKI production and Aircraft Overhaul Division for overhaul and upgrade of existing MiG Series aircraft.
Consequent on decision to manufacture AL 31 FP Engine for SU 30 MK1 Aircraft, under licence from Russian Manufacturer, it was decided to establish a new Division at Koraput to take up the project in February, 2002. The project activities under the new Division have accordingly commenced.
In order to facilitate Helicopter Division to dedicate itself exclusively for ALH manufacture and related activities,the manufacturing and repair / overhaul activities of Chetakand Cheetah helicopters and their variants where transferred to the Barrackpore Branch Factory and Barrackpore Division was formed and a new MRO Division created to carry out ALH Overhaul activities in 2006
Composites material is being used extensively in aircraft manufacturing for its low weight. A new Composite Manufacturing Division was formed in Mar 2007 with a dedicated manufacturing facility for composite materials for in-house projects such as ALH, LCA etc.

Additionally, Strategic electronics Factory at Kasaragod, Kerala, a unit of HAL Hyderabad, was established Nov 2012.
The in house development of Light Combat Aircraft (LCA) will give major boost to the modernization program of our Defence Services. For production of LCA, a separate Division was established at Bangalore for production of Light Combat Aircraft in Mar 2014.
