This GSLV Mk11 has fully indigenous engine.... and ISRO does not want another failure. it is not like earlier times when ISRO was just an arm of the Dept of S &T.. now its an international organisation with a lot of commercial interest. if this launch is a success, it will elevate isro's prestige among all space faring countries.

It is easy to get carried away when there's a good heap of past laurels .. but a long way to go.
Better avoid any show off this time.

i agree with you , Sir

but firstly thanks to rahiuds1 for this thread

secondly i wonder if the sarcasm of some of our members here is really justified - imho isro has done pretty well to get this far and the "failures" before this point are imho far less than most other countries - we usually later hear that even the usa had done umpteen trials till they got it right and hide behind and point fingers at india ( not so much the usa but others eg china )

this will be a landmark victory worthy of a national celebration and far more important than the icbm 5,000 km range achieved last year - in terms of technological skill

an indigenous gslv success will pave the way for india to seriously contend in space .

No doubt that there is a lot riding for GSLV on this Mk2 launch. Apart from it being a huge boost for India's standing in the commercial launch market, it will also be a confidence booster for the Mother of all Indian launch vehicles trial of Mk3.

Successful ignition of indigenous cryogenic engine

The hot-test took place in the newly-built high altitude test facility (HAT) at ISRO's Liquid Propulsion Systems Centre (LPSC) at Mahendragiri.

"The test was held at 7.55 p.m. on Wednesday, simulating the high altitude conditions to see whether ignition of the indigenously developed cryogenic engine takes place smoothly, as per the expected temperature, pressure and flow parameters," said Director of LPSC M.C. Dathan.

"The ignition was perfect and it gave all the parameters as per our predictions and it has given us an excellent confidence to go ahead with the GSLV-D5 launch from Sriharikota in July," he noted. The engine, which uses liquid oxygen and liquid hydrogen as propellants and develops a thrust of 7.5 tonnes, powers the GSLV's upper stage.

With the successful test, the indigenous cryogenic engine would be fully assembled and the cryogenic stage itself delivered at Sriharikota in a month's time. "Once it reaches Sriharikota, it may take more than two months to fully assemble the vehicle and conduct all tests. So we are planning to launch the GSLV-D5 in the second half of July," said Mr. Dathan.

GSLV-D5, with the indigenous cryogenic engine, will put into orbit a communication satellite called GSAT-14.

Mr. Dathan said the HAT facility was realised in a record time of one year. "This facility is a unique one in the country for testing cryogenic engines, simulating the high altitude conditions."

The launch of a GSLV-D3 with an indigenous cryogenic engine in April 2010 ended in failure. Although the engine ignited in vacuum in space, the ignition could not be sustained.


finally a good news for India:thumb:.i hope this cryogenic engine gets ready by the end of the year:cool2:

GSLV launch attempt in July

The Indian Space Research Organisation (ISRO) will make a fresh attempt at launching the Geosynchronous Satellite Launch Vehicle (GSLV), the last two flights of which have ended in failure, in July this year, ISRO chairman K Radhakrishnan said on Tuesday.

The GSLV will carry a communication satellite GSAT-14 to be put into the space.

GSLV is the second satellite launch vehicle developed by ISRO, the other one being PSLV, or Polar Satellite Launch Vehicle, which has just completed the 22nd successful launch in a row. The GSLV has been less lucky, with four of its 10 attempted flights, ending in failure.

"GSLV is an excellent vehicle, a beautiful vehicle. As compared to the PSLV, it is much less complex, except for one stage. It is far simpler to handle, though it has a large number of control components," Radhakrishnan said at a public lecture at the Indian National Science Academy.

The GSLV to be launched in July will be run on an indigenous cryogenic engine. Its assembly has started at Sriharikota facility on January 31, Radhakrishnan said. The cryogenic stage is being integrated and one more test is planned to be conducted later this month.

Radhakrishnan said the next generation of the GSLV, called GSLV-Mark III, which is expected to revolutionise India's space capabilities, would be launched in January next year. The GSLV-Mk III would be the heaviest Indian rocket to fly off, and would be capable of putting large satellites, weighing up to 5 tonne, into space. The present GSLV can carry up to 2.5 tonne.

GSLV-Mk III is also planned to be used for human space flights in future. "We are targeting an experimental flight of the GSLV-Mk III in January. Further development will happen after that," Radhakrishnan said.

The project director of GSLV-Mk III, S Somnath, said simulation of the flight were being done. "But there are certain tests that cannot be performed on the ground. So an experimental launch is required," he said.

Re: GSLV with indigenous cryogenic engine to be launched in April 2013

Currently India dependent of others countries to launch Heavy satellites

Desperately need GSLV ASAP for,...

1]Transponder:-
India Transponder crisis,Transponder crisis Partly due to not having the GSLV.
India is facing a huge gap between the number of transponders available on its various satellites and the burgeoning demand.
Presently have only 175 transponders and has taken on lease 86 from foreign country transponders.
The Hindu Business Line : ISRO left poorer by transponder crunch, foreign leases

2]To Launch Heavy satellites for India's own GPS/GLONASS(global positioning system) called IRNSS-'Indian Regional Navigational Satellite System,'

GSLV Mk3 heavy lift launch vehicle in January 2014.

Yep you are right.

There are going to be two launches of GSLV.

the one in July is MK.II in which ISRO will be testing again the indigenous third stage/upper stage Cryogenic engine for only the second time ever. The first attempt in dec '2010 failed due to the home built cryo engine failing to ignite.

The one in 2014 is MK.III which is newer design of GSLV capable of carrying heavier satellites and for HUMAN SPACE FLIGHT. This will have the indigenous upper stage cryo along with a newer second stage solid rocket booster called the S-200. Incidently the S-200 is the third biggest solid rocket motor in the world after the booster rocket of NASA's space shuttle and that of Arianespace's Ariane-5 launch vehicle. It is 22 metres long and 3.2 metres in diameter.

The attempt in 2014 for MK.III will have a empty third stage i.e the cryo engine will be dummy .So what is effectively being tested here is the rocket design and the initial stages including the S-200 is capable of withstanding all the G-forces and atmospheric pressures that come with achieving escape velocity. It will be most likely a sub orbital launch.

Re: GSLV with indigenous cryogenic engine to be launched in April 2013

Turbulence is more in actual flight rather then in the fixed condition of high altitude testing facility, we have seen few cases of wire getting snapped in flight (not of the cryogenic engine i guess). the real test happens only on the "mission to space", where in actual conditions. but i guess long time spending at isro backyard, the solutions for the engine failing to perform 100% would have been rectified. and i would be amazed if they have found a more better engine, while cleaning the wrinkles of the engine to perform to the needed potential.

Where is turbulence in empty space come from ..... when there is no airflow no turbulence. its lack of air that caused the last gslv failure, they failed to test the engine in vacuum (Kids knowledge). now they should have to send airtificial air for the turbofan to work.

ISRO to launch GSLV-D5 in July

Scientists at ISRO's Liquid Propulsion Systems Centre here are hopeful of finishing the work on the indigenous cryogenic engine by May 15 after its recent successful test at the high altitude test facility of the centre. The engine will be taken to Sriharikotta for the launch of geosynchronous satellite launch vehicle GSLV D-5 by July.

"A short-duration test in 3.5 seconds confirmed stable ignition of the cryogenic engine. A simulated high altitude condition was created with high capacity pumps in a vacuum chamber and the test proved successful, which has given us a lot of confidence. The engine will be completely ready by May 15, or at the most May 20, after which it will be taken to Sriharikota," LPSC director M C Dathan told TOI on Wednesday.

"One more HAT test is planned early next month to ensure the readiness of the cryogenic facility though it is not mandatory. A review meet of all senior officials of ISRO establishments will be held at Mahendragiri on April 29 to take stock of the facility," Dathan said.

The cryogenic engine uses a propellant combination of liquid oxygen and liquid hydrogen to develop a thrust of 7.5 tonnes to boost the cryogenic upper stage of GSLV-D5. He said the fluid line checking of the liquid oxygen and liquid hydrogen in propellants would be done at Sriharikota and the GSLV-D5 would be launched to put communication satellite GSAT-14 into orbit in the second week of July.

Vikram Sarabhai Space Centre director S Ramakrishnan said they had come a long way from the failure of the GSLV-D3 launch. "We had narrowed down the failure to the hydrogen fuel booster pumps of the engine. After a series of endurance tests and the latest successful HAT test, the engine is now ready."

He said preparations for the launch of polar satellite launch vehicle, PSLV-C22, were also in full swing.

Indigenous GSLV to be moved to Sriharikota by May 15

Ahead of its crucial and long-awaited launch in July or August, fully indigenous satellite launch vehicle GSLV-D5 is being readied to be shifted to the Sriharikota launch port by May 15, according to Indian Space Research Organisation (ISRO) Chairman K. Radhakrishnan.

GSLV-D5, powered by indigenous cryogenic upper stage, is being given final touches at the Mahendragiri centre in Tamil Nadu.

GSLV-F06, launched in December 2010 and powered by a Russian cryogenic stage engine, failed. Before that, the GSLV-D3, flown with a home-grown cryogenic stage engine, also failed in April 2010.

Since then, ISRO has made many modifications and corrections in the engine. It has conducted 35 ground tests and a simulated high-altitude test till as recently as March, Dr. Radhakrishnan said in his lecture in memory of Air Chief Marshal L.M. Katre on Saturday.

An Indian GSLV that can lift communication satellites weighing up to two tonnes into orbit is badly needed to keep up the satellite capacity for different users and the country's self-reliance in launching its own communication satellites.

Dr. Radhakrishnan said mid-June would see the launch of the first regional navigational satellite, R1A, [R one A] on PSLV-C22 rocket. After a review next week, the spacecraft would be moved to Sriharikota. This would be followed by launch of meteorology satellite INSAT-3D and advanced communication spacecraft GSAT-7 — from Kourou, French Guiana.
