    India aims to fly hypersonic plane in 2007

    Indian defence scientists are aiming to build a plane designed to cruise at speeds three times faster than existing fighter aircraft while consuming less fuel.

    The Hyderabad-based Defence Research and Development Laboratory (DRDL) is building an 8metre technology demonstrator, which will be powered by a supersonic combustion ramjet (Scramjet) engine that takes oxygen from the atmosphere and burns liquid hydrogen.

    "The ground tests of the engine would begin in 2005 and we aim to fly the unmanned aircraft in 2007," DRDL Director Prahlada told PTI in Bangalore.

    The aircraft would be built in India's aviation capital, Bangalore, and Hyderabad. It would be a high speed transport aircraft with an engine that does not have a compressor or a turbine.

    "The scramjet engine takes in oxygen from the atmosphere, liquefies it and uses it for the cryogenic engine, improving the efficiency of the plane by several factors because the weight of the fuel, particularly for long distances,�constitutes around 70 per cent of the total weight of the aircraft," officials said.

    The technology demonstrator would be a precursor to President A P J Abdul Kalam's dream project and DRDO's Aerobic Vehicle for Hypersonic Aerospace Transportation (AVATAR).

    India has achieved considerable progress in the air breathing engine technology (ramjet) at sub-sonic speed in its surface-to-air Akash missile programme, but is yet to master the technology at supersonic speed of up to Mach 7 (speed of sound is referred to as Mach). "We are improving on our expertise in air breathing engine technology and it would be used in an unmanned aircraft," Prahlada said.

    Incidentally, the country is in race with the US, Japan, Russia and China to build a hypersonic plane which is expected to revolutionise low cost space travel. The Indian Space Research Organisation has begun conceptual studies to build and launch a reusable launch vehicle using air-breathing technology by 2015, he said.

    DRDL is jointly working with academic institutions, including the IITs and the Indian Institute of Science, besides collaborating with the Mishra Dathu Nigam (Midani) to develop high temperature Nickel-Cobalt alloys and carbon composite materials, which could withstand heat during high-speed flight of the hyper plane.

    Which of the IITs??havent heard of them coming to IIT Delhi at least.

      IIT Kanpur I think.....But can come to others too

      I have some additional information on AVATAR





      The 'Aerobic Vehicle for hypersonic Aerospace TrAnpoRtation' (AVATAR) is a hyperplane concept from India. It is planned to be the size of a MiG-25 fighter and would be capable of delivering a 500 kg to 1000 kg payload to low earth orbit at a rather petty rate of $67 per kg assuming an airframe life of 100 launches.

      Weighing only 25 tonnes - 60 per cent of which is liquid hydrogen fuel - Avatar is said to be capable of entering into a 100-km orbit in a single stage and launching satellites weighing up to one tonne.

      It is also said that the AVATAR will make space solar power (SSP) stations affordable providing a global solution for the coming energy crisis. The idea being that a string of satellites in space will convert sunlight into microwaves and beam to earth where it will be turned into electricity. Till now SSP stations were unthinkable because of high cost of space launches but Avatar can change that, Indian scientists hope.

      Operation

      AVATAR would take off horizontally like conventional airplanes from conventional airstrips using turbo-ramjet engines that burn air and hydrogen. Once at a cruising altitude, the vehicle would use scramjet propulsion to accelerate from Mach 4 to Mach 8. During these cruising phases, an on-board system will collect air from which liquid oxygen will be separated. The liquid oxygen collected then would be used in the final flight phase, when the rocket engine burns the collected liquid oxygen and the carried hydrogen to attain orbit. The vehicle will be designed to permit at least a hundred re-entries into the atmosphere.

      Apart from AVATAR, Andrews Space & Technology (USA) Alchemist TSTO RLV is another concept that aims to generate LOX in flight.

      According to the Designers, Hyperplane projects of the 1980's - the X-30, Tu-2000 etc, failed due to their immense weight. Hence it is the weight which is the promising aspect of AVATAR.

      Development

      AVATAR or Avtar was first announced in May 1998 at the 'Aero India 98' ehxibition held at Bangalore. Initially it was then called the 'Aerobic Vehicle for Advanced Trans-Atmospheric Research', which means that it has now progressed into a more viable RLV and military role.
      Avtar means rebirth in Sanskrit, signifying that it is a scaled-down version of the first 230-ton Hyperplane India promoted in the early 1990's but later abandoned because of its high cost, estimated at $10 billion to $12 billion.

      The AVATAR is being developed by India's Defence Research and Development Organisation or DRDO. Air Commodore Raghavan Gopalaswami(Retd.), former chief of Bharat Dynamics Ltd, Hyderabad (which produces India's military missiles) is heading the project. He made the presentation on the space plane at the global conference on propulsion at Salt Lake City (USA) on July 10, 2001. Gopalaswami said the idea for Avatar originated from the work published by the Rand Corporation of the United States in 1987. "They threw the report into archives. It came to me as an unclassified document and formed the basis for our approach," he said.

      The AVATAR is currently only in the conceptual stage. The initial development budget is only $5 million, but project supporters claim that the vehicle can be built in ten years with total funding of under $2 billion. Designers admit, however, that international assistance would be required for the project to reach its goal.

      In addition to the DRDO team working on the conceptual design, development of technology components is being undertaken by as many as 23 academic institutions (IITs, IISc etc) in India as well. A Hyderabad-based private company CIM Technologies is also participating in the project.

      Both the scramjet engine concept and the liquid oxygen collection process have already undergone successful tests at DRDO and at the Indian Institute of Science, Bangalore. DRDO has approved further testing of the liquid oxygen process and assigned a team to conduct a detailed review of the vehicle’s design.

      Currently DRDO plans to build and fly a scaled down version called Light-Avatar (LAVATAR?), weighing just 3 tonnes at take off. To be built by CIM technologies by 2006, mini-Avatar will not go into space but will demonstrate all technologies used in Avatar including oxygen collection. It will use the India's Kabini jet engine.

      It is claimed that the real AVATAR would be viable by as early as 2013-2015(!) - provided international co-operation is available. This is highly unlikely, since 'cooperation' here would result in violating the Missile Transfer Control Regime (MTCR), which has been vigourously applied to India and Russia when India wanted tranfer of Cryogenic engine technology from the latter in the early 1990's.

      Interestingly, AVATAR design has already been patented in India and applications for registration of the design have been filed in patent offices in the United States, Germany, Russia and even China.

      Hypersonic flight is one of the most important objectives of space industry and science. It will open up a new way of travel, not only to space but to different parts of earth. A lot of research is going on all round the world to make it possible. NASA's X-43 is the biggest of them all. A lot of pioneering work is required. While India has done some ground experiments, it is still far from producing it's own air-breathing rocket engine. Indians have'nt even mastered cryogenic engines , technology now taken for granted in the west.

      The primary objective of X-43 is to flight test the scramjet, which is the obvious first step in this direction. No other project has gone far as it has. The first test flight took place on 2 June 2001, which failed. Other AVATAR-like projects include USA's HyperSoar and erstwhile programs like Tu-2000 (Soviet Union) and X-30(US).

      February 2002 - G. Madhavan Nair, Director Vikram Sarabhai Space Centre (VSSC) told journalists that "We have plans for a reusable two-stage vehicle which can take off and land like an aircraft". He expected this system to reduce existing launch costs by a factor of 10 (The Times of India, February 4, 2002). It is not clear what vehicle this is, whether it is a new concept or perhaps the result of continuing research on AVATAR.

        nice, just to mention Russia's project, it is known as the AYAKS(AJAX in english) and it will be capable of reaching Mach 10 cruise speeds, and will ce reconfigured into three roles, hypersonic transport, hypersonic fighter aircraft, and hypersonic bomber aircraft, it will reach, or should reach IOC in 2010
        for MOTHER MOLDOVA

          Russia will do it much before than India i think. So India will have one hypersonic plane before its own AVATAR . You know Russian ll give give India if they ask.

              Dima,
              some things are taken as obvious about india and russia here. They are supposedly helping us with nuclear submarines, giving us stuff lke MKI codeveloping stuff like Brahmos and PAK-FA. So they wont have much problems in helping out with hypersonic project for money.

                whatever i have said should be there in future.
                I said so because Indian and Russia both have very good military relation .Now India is becoming Its parterner in Some projects .
                We all know Brahmos is a success .
                Pak Fa (T 50) is there.

                Russia never say no to India for a Plane.
                So I said if russia makes a hypersonic plane before India then there is possibility to great extent that india will get it If they asked for it.

                If you have any furthar comments kindly reply

                  um, i'm not sure about a hypersonic aircraft, this is pretty imp(as ajay would say) for Russia, here are some links

                  http://mae.princeton.edu/milesgrp/pd...20in%20MHD.pdf

                  i'll have to ask my friends for more links, they provided some really solid good links on it

                  as for Military relations between Russian India, yes they are very clsoe, but, to share this wiht India, i don't know, i don't think Russia would want to share technology like this, and if they do, its performance will be greatly lower than that of the original

                    Why Dima???? Are you insinuating that our Indian buddies are stupid?

                    And that because of their input in this hypersonic aircraft technology, the final product will come out degraded?

                    Dima man you crack me up.

                      You mean to say that Russia gives India 2nd grade tech.

                      Well You should not say so .

                      MKI is given by Russia to India , Everyone talks about MKI why not MKK or others so much.

                      And PAK FA , Why they made India their partener in the project. If you say for money then they could get it from china too. And will india not get the tech. of PAK FA if its in project...?? Yes it will.

                      And there will no problem for russia to give india a hypersonic plane as it knows India ll produce its own pretty soon. Russians will help india in the project or may give necessary tech.

                        no, because China denied wanting to join Russia in this project, they were already developing their own, and you know, those dang chinese, China was the first country asked, because of their greater financing potential

                        yes, 2ed grade technology, except the MKI, regarded as the best Flanker variant, i want to debate with that, but, that roughly seems accurate, most export models delivered to other countries are always downgraded from the original, take the T-55's used in the Gulf War, the Russians made the armour of stamped steel sheets, instead of molded, or something like that, which resulted in weaker armour

                        yes, it will get the technology, but not necessarily as advanced as Russia's, they may have warm ties with each other, but Russia won't give away it's absolute best technologies away

                        for the hypersonic aircraft, they may sell some components of the technology, but they won't give it to India, too valuable

                          MKI was an exception There may be other exceptions ...who knows. :)

                          But i Agree . Russians will give what they think they can keeping best in their hands . They want India to ask from them . They ll not creat situations where they ll have to ask India for anything except money.

                            Well buddy, we took the airframe with increased range from u with canards and 3DTVC ( u gave us all) the best radar u had ,and then we took all the good avionics from israel gfrance and developed our own ( like mission computer) where we couldnt find somthing up to the mark.
                            Well With india russia has no insecurities about stuff flying in wrong hands /used against them so they feel secure and thats why they made a stuff like MKI for us while giving their bigger aircraft customer a degraded one( without TVC).

                            yes, it will get the technology, but not necessarily as advanced as Russia's, they may have warm ties with each other, but Russia won't give away it's absolute best technologies away
                            Well now we are developing the aircraft together . We have dont the brahmos together. And we will get all that comes into the two without any degradataion. And tahts ebcause we wont invest if given degraded stuff.


                            for the hypersonic aircraft, they may sell some components of the technology, but they won't give it to India, too valuable
                            LOL.. Well even TVC(3D) is too valuable but they still gave it to india. even the PAK-Fa roject is too valuable but they still partnered with india to share teh cost and the product from the development.

                              I also feel if china was asked for such project then why it denied. I dont think for its JF 17 it will say no to PAK FA.

                              BRAHMOS or T 50 , India must have the full tech being a partener.

                              But Dima Says Russia ll not give Full tech. for some of its main projects.Well he can be right to some extent....

                              I need more comments....
