    The Indian Space Research Organisation on Tuesday successfully test-fired the indigenous cryogenic engine CE-20 for 645 seconds. This significant development can push India into a bigger league of nations launching satellites weighing up to five tonnes.

    The event also marks a landmark in India’s effort to develop a big cryogenic engine that can put GSLV Mark-III into geostationary orbit by the end of 2016.

    Prime Minister Narendra Modi congratulated ISRO on this occasion.

    That is 10 mins :D last test was 20 seconds ..... all set for new launch vehicle in 2016 :lol:
    Onward Ho!

    @power_monger,

    What does it mean now?

    The earlier cryogenic engines used were Indian and none helped India?

    ^^^ :lol:

    But from 70 KN Russian engine to 75 KN CE-7.5 engine to 200 KN CE-20 engine is quite some journey.

    Somebody must have helped but somebody must have worked to scale up the idea also.

    Congratulations to all - known and unknown.

    There is no harm, shame or embarrassment to update or borrow technology, but not steal like the Chinese, from those who are masters at it in that field.

    But to not acknowledge the same and claiming it to be original is deceit as also false ego.

    Let us be honest and a straight nation.

    Cryogenic Engine for Rocket Undergoes Crucial Test
    Published February 20, 2016

    The high-performance India-made cryogenic engine meant for the hefty GSLV Mk-III rocket (LVM3) successfully underwent a 640-second firing at the ISRO Propulsion Complex (IPRC) at Mahendragiri, Tamil Nadu, on Friday evening, ISRO officials said here on Friday.

    ISRO chairman S Kiran Kumar, who attended the test, commented that it was “a phenomenal achievement in the shortest time. Fully indigenous cryogenic engine development for GSLV MkIII and a major step towards GSLV Mk-III launch in December 2016.” The engine had already undergone two short duration tests. The test was conducted with Mixture Ratio Controller (MRC) in a closed loop mode for the flight duration of 640 seconds, the ISRO said in a statement here.

    This is the second cryo engine on which the hot tests are being conducted. A third engine identified for actual flight use will soon undergo tests at Mahendragiri soon. ISRO had first successfully used an indigenously-built cryogenic engine for the GSLV Mk-II rocket on January 5, 2014. But that engine, designated CE-7.5, is a less powerful version of the CE-20 meant for the bigger GSLV Mk-III.

    If things go as planned, the CE-20 will power the upper stage of the GSLV Mk-III for the first time in December this year. Developed by ISRO’s Liquid Propulsion

    An exactly similar test was done on 29.4.15 and claimed as success.

    it can take only 4000kg payload ?? i thought mk3 was being made to take heavier n bigger satellites .

    "Only 4000kg payload"?
    Heaviest communication sattelite made by India was GSAT-10 launched by a French Ariane rocket. That weighed 3100 kg !!

    Compton Gamma Ray Obs.16329 kg. Hubble Space Telescope 11110 kg(launch mass) Space observatory in LEO.
    Envisat 8211 kg Retired earth observing satellite. TerreStar-1 6910 kg American communications satellite. Terra 4864 kg Earth observing satellite

    if u have payload capacity of 250 kg then u will not make 1000kg gizmos and if u do then u have to depend on others.
    isro calls herself world class with only 4000kg payload at max

    See it will be 4000 KG+ payload with MK3. When semi cryo will come in the load shall increase to 6000kg+. When many metal parts such as pumps and motors shall be replaced with light weight material than geosynchronous load shall go up to 10 tons and LEO load shall be 22 tons.

    Yes but MK-III and Cryo are different things
    ** engine assembled with boosters etc = Launch vehicle..
    **Cryo engine= engine.

    So this is just a piece of the puzzle .. This engine+ booster + other engines all together determine the max load.

    Obviously, US's Delta IV heavy lift rocket is on your mind; but that phenomenal lift capacity doesn't come from cryogenic 2nd stage (110Kn thrust cf. GSLV MK3's 186Kn). It is the massive common booster core (CBC) liquid motor (134 ft tall, 3312Kn thrust) that provides the sinew.

    Boosting power can be significantly enhanced by strap-on auxiliary motors, but the paradox is bigger the core stage or more the number of strap-on, the heavier the rocket becomes at take-off stage and more chance of failures.

    Payload to GTO would be 4000kg,while the payload to LEO would be 10,000 Kg.When theL 110 stage is replaced by the semi cryo,SC 160,GTO payload would go up to 6000 kg.

    A 10 tonne to GTO,class Heavy lift launcher is already under design.

    Guys, in crygenic engine wiki page, I saw CE 7.5 & CE 20. But upper stage engine thrust of CE 20 is 200 kN, way ahead than that of other countries! What does that mean? Is it significant achievement?

    no, it can lift 6000kg to GTO and 12000-15000kg to LEO.
    Rocket launched is 2014 was an underpowered version and was later modified for more thrust in 2015.

    No, o_O
    Just after launch of smaller LVM3 version in 2014, full scale version launch was scheduled in December 2016, 2017 was a speculation if some technical problems could obstruct.
    But fortunately, no problem occurred.
