Visakhapatnam: Vizag-based public sector undertaking BHEL-HPVP (Bharat Heavy Electricals Limited - Heavy Plates and Vessels Plant) is engaged in indigenous development of new types of compact heat exchangers (CHEs) for the Light Combat Aircraft, also known as Tejas.
According to BHEL-HPVP sources, the research and development department at the plant is currently engaged in indigenous development of four new types of CHEs for the Mk2 version of the Tejas aircraft (LCA-Mk2).
Sources said BHEL-HPVP will be supplying 40 of these new CHEs under a project for the Aeronautical Development Agency (ADA), Bangalore, a DRDO agency. This will be in continuation to the earlier CHEs supplied for the LCA. Official sources said Hindustan Aeronautics Ltd (HAL), Bangalore, has recently inquired with HPVP for supply of a further 100 sets of Tejas heat exchangers. Also, sources said the Indian Navy is planning to order another 40 sets of Tejas heat exchangers in the coming years.
Including those supplied during the development stages, HPVP has so far supplied over 400 compact heat exchangers to ADA and HAL.
Recently, the Tejas were inducted into the Indian Air Force, fitted with compact heat exchangers supplied by BHEL-HPVP, which officials said is a landmark achievement for any indigenously developed item.
After completion of successful development of CHEs for Tejas, HPVP has manufactured and supplied over thirty aircraft sets of Tejas heat exchangers to ADA and HAL under their Limited Series Production (LSP) and Series Production (SP) programmes. CHEs supplied by HPVP are fitted on board every Tejas flown so far and have clocked several hundred hours of flight with consistently satisfactory performance.
The R&D department of BHEL-HPVP, has successfully developed eleven different types of compact heat exchangers indigenously for the Indian LCA. Starting from mid 1990s, these developments were carried out over a period of ten years under successive development contracts assigned to HPVP by the Aeronautical Development Agency (ADA).
Officials said these exchangers are both compact in size and light in weight, making them best suited for aeronautical use. They play the vital roles of maintaining a controlled environment for the pilot and preventing the hydraulic and lubricating oils in the aircraft from excessive heating during flight. Making of these heat exchangers requires high quality machining, vacuum brazing and welding technologies apart from design and engineering.
According to sources, the CHEs developed by HPVP for the Tejas have undergone and passed the severe pre-flight qualification tests mandated for any airborne equipment. On their successful qualification, these CHEs have been accorded the 'Type Approval' for use on board the Tejas by the air-worthiness authorities in ministry of defence. These heat exchangers have been developed and manufactured for the first time in the country at HPVP, who continue to be their sole suppliers in the country to this day. HPVP is thus counted among the select few firms worldwide with the capability to design and manufacture state-of-the-art heat exchange equipment of international quality for military aircraft.
