Hindustan Aeronautics Limited (HAL) has delivered the first fully indigenous fourth stage propellant tank (PS4) of Polar Satellite Launch Vehicle (PSLV) to Indian Space Research Organisation (ISRO) recently, the company said today.

''The indigenisation effort has resulted in foreign exchange savings of Rs1.2 crore'', said R K Tyagi, chairman, HAL.

The PS4 tank is a part of the fourth stage of PSLV. It will carry 1.6 tonnes of liquid propellant Mono-Methyl Hydrazine (MMH) as fuel and Mixed Oxides of Nitrogen (MON-3) as oxidiser during the flight.

The machining of all parts for this tank is carried out at HAL and the welding work is carried out at Liquid Propulsion Centre of ISRO and HAL. The raw material is from Midhani and BHPV.

This successful indigenisation has been achieved by through coordination among four government agencies - HAL, BHPV, Midhani and ISRO - the company said in a press release.

HAL has 19 production units and 10 research and design centres in 8 locations in India. It has been successful in numerous research and development programmes developed for both defence and civil aviation sectors.
