    India's hypersonic missile dreams are slowly and steadily taking shape at the DRDL facility in Hyderabad, with the advancements of HSTDV project. Though scientists are tight-lipped about letting out too many details at this stage, Tarmak007 can confirm that the project is definitely heading in the right direction with the boost it might have received after the missile brain in Dr Saraswat took over the reins of DRDO. | Photos: Tarmak007 .

    Bangalore/Hyderabad: Forty kilometers in 20 seconds! The time taken to eat a biscuit. Well, that's the primary mission objective scientists at the Defence Research and Development Laboratory (DRDL) in Hyderabad are
    aiming for, probably as a first step towards unleashing a futuristic hypersonic cruise missile. And, when Santa rings
    the X'Mas bell in 2014, we would have known the fate of this tech-cocktail currently being measured and mixed to
    perfection by a group of brainy boys of Indian defence. The scientists have already conceptualized a Hypersonic
    Test Demonstration Vehicle (HSTDV) for an autonomous flight of a scramjet-integrated (combustion inside the engine occurs at 1.2 km/sec) hypersonic air-breathing vehicle for a short duration of about 20 seconds. The scramjet-integrated vehicle is mounted on top of an already proven Agni missile booster motor and protected
    by aerodynamic fairings. The solid booster injects the hypersonic vehicle at the desired altitude of 32 km and
    Mach number of 6.5. The aerodynamic fairings are separated and the hypersonic vehicle is also separated from
    the booster. After separation, the scramjet engine is ignited and the vehicle cruises for a short duration of 20 seconds. High temperature materials are used for the engine and airframe construction. The scramjet integrated vehicle has been designed considering the aero-propulsion interactions. The performance analysis indicates the capability of the vehicle to generate adequate positive thrust margin ensuring cruise condition. “The materials have been identified, thermo-structural design completed and the airframe also fabricated. A scramjet combustor also has been designed and tested in connect pipe mode test facility at DRDL and the performance has been satisfactory, so far. A flight-worthy engine using high temperature resistant materials is under fabrication," sources
    said. The first aerodynamic wind-tunnel test was held in Israel (2007) and later in Russia (2009) as India doesn't have a hypersonic facility to test larger cross-section of platforms. "Next year some more missions are planned in Russia, including stage separation and air intake tests. We are also planning a full-scale panel-separation test
    at DRDL itself," sources told Express. The scientists have already proved technologies for aerodynamics, aero-
    thermodynamics, engine and hot structures through design and ground testing. "Ahead of the launch, we will have to now focus on the mechanical and electrical integration, control and guidance system along with their packaging, checkout system, HILS (hardware in loop simulation) and launch readiness," sources said. Technologies like configuration tests, combustion and full-scale cruise vehicle structural aspects have also been proved taking
    the project past the half-way mark. India is the second country to have planned an autonomous flight of the hypersonic air-breathing vehicle; the first being the USA which demonstrated the flights through X-43 and
    X-51 programs. France is also planning the autonomous flight sometime in 2015 through LEA program.
    The HSTDV project directorate was formed in 2005. It is now confirmed that technology for a 600-second test to cover a range of 1,500 km range is also taking shape to establish future strike technologies against hardened and time-critical targets.

    I think the same can be used for launching satellites too then? So all in all Agni is a delivery vehicle, not a kill vehicle

    Thanx for correcting the text format for me.
    Some time if i post from cell it tends to disstort the space formate of artical and i was trying to correct that format for this artical .

    Complety noob in this and couldnt find any nice detailt about it.

    Could somene please explain for what thus this HSTDV will be used for

    Article says it can launch satellite into space, but what difference can it make. The present ISRO Rockets can do the same.
    Can it be any use for Military purpose?

    This is not the ISRO scramjet test vehicle (ISRO tested it two years back). HSTDV will be used to collect necessary data for Brahmos-2

    sad to see even after so much of things coming up and dozens of laboratories and test centers lined up in this country, wind tunnel test for these high value vehicles are done is russia.

    just think, this thing is first dismantled and packed- weeks of work.
    then transported to russia-week or so
    opened up and joined again- weeks.
    testing in wind tunnel and data collection-weeks if not months.
    again dismantling and packing-weeks
    transporting to India-week or so
    again opening and assembling- weeks.

    then comes the intermediate step- system changes and applying the changes thus finalized after data analysis.

    in the above layman analysis. we can see that crucial prototype testing takes months in total of unnecessary assembly and dismantling, transportation. and after making due changes one need to repeat the above procedure to validate the changes means again a new russia trip.

    this trip also include charges for sending and protecting model and that of scientists.

    who the hell is not sending proposal to make a wind tunnel. im sure my university VC or prof from IIt can design it.

    India does not have a wind tunnel for testing and validating designs with complex hypersonic air flow and resulting boundary layer separation that would happen at the intake or while separation of HSTDV from the booster rocket. Besides, what's the fun in JV is both the partners, instead of pooling their assets together, indulge in redundancy of facilities and equipment thereby nearly doubling the project costs ?

    Send my regards to your university VC. Also, tell him that he is a very talented guy and the country needs him :hail:, for he can single handedly design a hypersonic wind tunnel with bleeding edge sensors for testing a technology, which is considered by NASA to be the next big step in space launch vehicles, something that even Richard F***ing Branson could not provide his designers with all the money in the world for Virgin Galactic, a task of such complexity that IAI, with all the US funding and some of the best research labs, backed off from HSTDV project and India roped in Russia for the task with the promise of integrating HSTDV research with Brahmos-2 project.

    Something is definitely wrong with such a brilliant researcher doing such a mundane low paying job (for a man of his talent) or its just a case of you having a condescending attitude towards our research establishments.

    in simple terms- till when do you think that so called JV with russia will go on. a country whose policy is to have only partners and no friends. this partnership can end anytime.
    a laboratory set up can be called a burden on project cost if you consider that to be used only in one single project. like ADE, if you think its role was only uptil designing tejas then yes, its a liability now. but if you think that it will be in popular use for more systems to come and for more modifications and mark2 to roll out then it will be an ASSET like hal.
    russia... no.... soviet union was great partner of India. India could have done anything with it but with russia. i dont think the dependability should be so high that testing is done their. of course when we dont have a lab then we have to go there but why not have a lab here. this is not the only project going on, the similar one is on with isro.
    so at a time you have two project and not the testing facility. why not.
    complicated air worthiness center is set up and on the other hand hyper sonic wind tunnel is considered impossible for us?
    richardbranson couldnt finance his own wind tunnel ok fine... russian did it and many other countries did it, so why consider India cant do it.

    hypersonic wind tunnel is surely a technical difficulty but i dont think there is a reason India cant develop it.

    moreover my VC is not an idiot babu. he was chief designer of wind tunnels for rolls royce. before coming back to India. but now he is lazy

    India has a wind tunnel . This is where Brahmos 2 was probably tested??

    http://www.thehindu.com/sci-tech/science/article2019409.ece

    They include a hypersonic wind tunnel to study re-entry and a plasma wind tunnel to study the behaviour of materials at high speed, which would be set up at the Vikram Sarabhai Space Centre in Trivandrum.

    India To Boost Missile, Avionics Research at Hyderabad

    Hyderabad currently houses India’s sole missile production complex, Bharat Dynamics, and the Defence Research and Development Laboratory, which is helping to develop India’s future anti-ballistic missile defense program. The hypersonic test facility is part of that program, which aims to develop a system to shoot down incoming enemy missiles at a height of more than 100 kilometers using hypersonic missiles.

    Forgot to add UK's QinetiQ's scramjet efforts.

    Yes Lethal force, India does have hypersonic test facilities, and ISRO scramjet demonstrator is a proof that the basics of scramjet design are sound, but that is it. HSTDV has to move from an experimental stage to product stage at a rapid pace, and overcome the problems that have plagued almost all scramjet programs at the same time, else it would take another 20 years in weaponising scramjet technology. DRDL labs do not have the resources to study the inside of a scramjet engine and there is only a limit to where computer simulations will lead you to. That leaves too few organisations in the world that have actually flown a scramjet and are working towards real world models with sustained flight; ei NASA, DARPA, DSTO (Australia) and CIAM (Russia). NASA will not cooperate on a weapons project, forget DARPA and DSTO. That leaves us with CIAM (the first ones to fly it and having massive amounts of data already).

    but you will agree that its not one time project. it will take atleast a decade from now to complete it and induct it. moreover its a weapon delivery system which reusable at the same time.
    so at most a dozen of it will be made and delivered to sfc and the constant research in it is expected so that technology matures and better platforms are given out to force because china wont be sitting idle in the meantime.
    having a hypersonic wind tunnel like CIAM of russia is a long term investment.

    Israel is also involved in this project. If we really are lacking in a test facility maybe
    Russians can help??(also rumored to be helping)I cannot believe scientist would work
    on something without being able to test it. Maybe all things are not revealed??

    Where are cryogenic engines tested?? Speeds are usually 4.4 km/sec

    4.4 x3600=15,840 km/hr

    mach=1195/hr

    15,840/1195=13.255 MACH or greater.
