BHEL developing new types of compact heat exchangers

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.

This is very impressive. So far as plane development is concern, there are 2 aspects to it. Make is light and make it more aerodynamic and then if possible, make it more stealthy within the limits of aerodynamics. This sort of compact and light weight LRUS shall allow weight reduction and also release the space giving flexibility to designers to rearrange LRUS. If i had been the project incharge, i would have asked LRU suppliers to look at each LRU and come out with a proposal that what value addition can you make to these LRS in terms of saving in weight and compacting it in size. if we can take this approach to all LRUS than we can make an all together a different plane. So this is an excellent development and if 50 to 100 KG weight is reduced, it is significant.

The Commanding Officer of the Indian Air Force squadron ‘Flying Daggers 45’, Group Captain Madhav Rangachari in a recent interview said that the Tejas was the best aircraft that he had flown.

"It’s an excellent aircraft and generation ahead of other fighters in the world. Being the only of its kind (light combat), it’s not comparable with other military aircraft” he said.

The Tejas is equipped with a quadruplex digital fly-by-wire flight control system to ease handling by the pilot. The digital FBW system of the Tejas employs a powerful digital flight control computer (DFCC) comprising four computing channels, each with its own independent power supply and all housed in a single LRU.

Why would Lockheed Martin invest in a Tejas Facility unless it was a part of offsets for an yet unannounced F-16 blk70 deal.
For C-130J deal there is an offset obligation. Similarly, Boeing has for C-17s which they are meeting in form of an engine test facility (a high altitude test facility).

KH-T- 2010 finds her way through the mountains..

"Please share or repost only with ‪#‎Tejas_LCA‬ #Tejas_Official_Archive and the write up, not merely copying or editing the image...
With Tejas-T being tested in the full spectrum it is now amply clear that this aircraft is not just a two-seat trainer but also a fully functional combat platform. And this should debunk an age old misbelief!.

The inclusion of these two blatent LIES:

1) "Grounding" of LCA
2) This is the second fighter for the IAF's operational fighter SQN

Highlights simply how bought some sections of the Indian media are and/or how dismissive they are of India's own capabilities to this day.

I had to read about halfway down the page to learn that the "grounding" was actually simply an extended stay of an EXPERIMENTAL aircraft at a airbase/airport quite some distance from "home base" caused by unfavourable weather conditions.

I do hope that it is understood that any development program ANYWHERE in the world would have done the exact same thing. The a/c is NOT a production model but an experimental fighter (hence equipped with all kinds of gadgetry; sensors, on board computers, extra data links, that would never appear on operational a/c) and thus a one off that they cannot afford to take any risks with. Furthermore, the fact that the a/c was on a deployment/test AWAY from its homebase means the test team would be even less inclined to take any risks as there would not be support/spares readily available for the type.

The ADA/NFTC's zero-risk approach is why there has not been a single airframe loss to date and minimal flight safety incidents.

The fact that the Indian media even reported on this is utterly bizzare.


Keep going ADA/HAL/Team Tejas, prove all your doubters wrong

A day will come when LCA will crash.. think of it.. what this Media will Do ??
