    Detailed Analysis by Peter B. de Selding:
    France and India to study future rocket designs, including reusable vehicles[​IMG]India's PSLV rocket lifts off in June 2014 carrying Airbus Defence and Space's Spot 7 Earth observation satellite, two years after the launch of the identical Spot 6. India's PSLV has increased its annual launch rate, making it a serious competitor to Europe's Vega and Soyuz vehicles. The French and Indian space agencies are nonetheless working together on future launcher studies, with France helping India transfer PSLV production from India's ISRO agency to industry. Credit: ISRO
    Europe’s launch sector uncertain of economic model for reusable rockets
    CNES’s Astorg: Joint work to have no effect on Europe’s Prometheus engine
    In brief, we'll get more launch contracts from France if we can launch heavy Satellites in cheap price also.

    I think the plans have changed & ISRO is going for different configuration. The ULV concept is abandoned I guess.

    This is from the abstract of a talk on 'Future of Space Transportation' by Shri. S. Somanath, Director, Liquid Propulsion Systems Center at National Space Science Symposium.

    ''The semi-cryogenic stage with 200 ton propellant loading will replace the present earth storable core stage of LVM3 to enhance the payload capability to 6 tons. A heavy lift launch vehicle having 8 to 10 ton GTO payload capability based on bigger solid boosters, a semi-cryogenic core stage and clustered cryogenic upper stage is configured and is under detailed study. A clustered semi-cryo booster stage with 4 to 5 engines and with 500 ton propellant loading can be the booster stage of future heavy lift vehicle or a two stage human rated vehicle. Such a semicryo booster stage can be recovered and reused as well taking advantage of the throttling capability of the engine.''

    LVM 3 upgrade road map towards HLV.

    HLV (?)

    [​IMG]

    And they are contemplating partially reusable VTVL launchers with 5 engine clustered configuration for first stage. That stage looks good enough for a moon rocket !!!

    [​IMG]

    Payload to GTO is some 14 tonne.

    There is one doubt I have regarding the Super Heavy Launcher .

    If you look at that design , we have boosters with 500 tons of propellant powered by a 4 engine cluster while the core with the same propellant loading is powered by a 5 engine cluster .

    Doesn't that mean the core will be emptied before the boosters and the LV will have to carry the dead weight for quite some time till the boosters also finish off ??

    This will make it an inefficient design like the GSLV MK2 where als the problem was same ..... core emptying out before the boosters .

    @Indx TechStyle @GSLV Mk III

    When is the next Experimental RLV launch....!?

    There was some chatter online about 2 of their experiments being merged into one...and that there will be 3 experiments in all...
    I am most excited about SPEX......and LEX
    RLV is very interesting....Even if they make a platform which can launch 4-5 t to LEO....They will very significantly reduce the launch costs.....

    I don't expect it yo be as capable as the American Shuttle...But it doesn't have to be.....
    I just hope it significantly reduces launch costs.....


    The Americans seem to be racing ahead on that front with Space-X demonstrating some cool re-usable concepts like the Falcon Booster Landing...we need to catch up....

    The RLV is a looooooong way from even remotely competing with SpaceX launchers. Rest assured we're not catching up anytime soon.

    For the next 5-10 years, our focus will be on consolidating our market presence, and building on it.

    In the very short term...I am waiting for the Mk3 and The 103 SAT PSLV XL.....


    In the long term....
    If we somehow make the Mk.3 a reliable LV... It can be used as an initial platform to test the SCE200's...

    The Electric Propulsion....MOM2 ....Chandrayaan 2...SCE200 the RLV......and the New Family of LV's....Are perhaps the most interesting missions in the coming few years...
    Rest of the stuff although technically difficult...Is quiet boring (given the technical prowess of ISRO)....



    PS : THE SCE200 is the most interesting....The MOST.....I can't emphasize it enough THE MOST MOST MOST interesting, promising and perhaps the most Challenging projects of all....

    Once done...Oh boy...That will open a Pandora's Box of Opportunities.... Clustering....HLV...Moon Missions..And MOST Importantly....No more begging for Heavy Launches...
