ISRO to mate cryogenic engine with its rocket on Friday
Thursday, Jul 4, 2013, 21:51 IST | Place: Chennai | Agency: IANS

ISRO chairman K Radhakrishnan had announced that GSLV rocket powered by India's own cryogenic engine carrying communication satellite GSat-14 will be launched on August 6.

The Indian space agency will be mating its own cryogenic engine with its heavy rocket - the geo-synchronous satellite launch vehicle (GSLV) - Friday afternoon at its spaceport in Sriharikota in Andhra Pradesh, said officials.

"The process of fixing our cryogenic engine with GSLV will begin tomorrow (Friday) afternoon. Then various tests will be carried out before the satellite is fixed with the rocket," an Indian Space Research Organisation (ISRO) official, who did not want to be named, said.

ISRO chairman K Radhakrishnan had announced that GSLV rocket powered by India's own cryogenic engine carrying communication satellite GSat-14 will be launched August 6.

This will be the first mission of GSLV during the last three years after two such rockets failed in 2010.

One of the GSLV rockets flew with Indian cryogenic engine and the other one with a Russian engine.

The GSLV is a three stage/engine rocket. The first stage is fired with solid fuel, the second is the liquid fuel and the third is the cryogenic engine.

GSLV D5 mission: Isro begins tests on indigenous cryo engine

By Meera Vankipuram   Jul 09 2013 , Chennai

The Indian Space Research Organisation (ISRO) has commenced testing the indigenously developed cryogenic engine, which has been mounted on the Geosynchronous Satellite Launch Vehicle (GSLV) — MK II.

Isro chairman K Radhakrishnan had announced earlier that the GSLV D5 mission, carrying GSAT-14, the communication satellite, would be launched on August 6 fr om the Satish Dhawan Space Centre at Sriharikota.

"Vehicle integration is going on at present. The cryogenic engine has been mounted on the launch vehicle, and elaborate checks are on," Isro spokesperson Deviprasad Karnik said.

After a series of successful high-altitude tests at Isro's Liquid Propulsion Systems Centre (LPSC) in Thiruvananthapuram in the last few months, the engine was moved to Sriharikota, from wh ere the GSLV will be launched.

The GSLV is a three-stage vehicle — the first stage has solid fuel, and the second stage is an engine carrying liquid propellant. The third stage, the indigenously built cryogenic upper stage, uses cryogenic propellants. According to senior Isro officials, the cryogenic stage enhances India's indigenous capability to launch communication satellites and other ambitious space missions.

This launch is crucial for India as the previous two GSLV missions in 2010 were unsuccessful. Of the two previous missions, one of the launch vehicles was fitted with the Indian cryogenic engine.

The cryo-powered GSLV rockets are important for the country's future space programmes like Chandrayaan-2. All the initial GSLV missions were fitted with cryogenic engines purchased from Russia. In 1992, when the United States pressured Russia to deny India the cryogenic technology, India decided to build the engine on its own.

Since then scientists at Isro have been working on developing an indigenous cryo engine, tested in a previous GSLV mission in 2010, which ended in failure.

ISRO gets busy with GSLV launch
Special Correspondent

After slotting its nine-day-old navigation satellite, the Indian Space Research Organisation (ISRO) now turns full steam on its next and high-stakes test, the flight of the Geo Synchronous Launch Vehicle (GSLV) medium-lift satellite launcher.

ISRO Chairman and Department of Space Secretary K. Radhakrishnan on Monday said the launcher, numbered GSLV-D5, was planned for launch in the second week of next month but not before August 6.

After two-and-half years

The GSLV, which is so crucial for the country's space programme, is being resumed after two-and-half years. Two consecutive launchers flown in 2010 failed, setting back the programme and putting the vehicle and the indigenous cryogenic stage through rigorous checks and tests.

It will be also the second outing of the homemade cryogenic stage, in place of the Russian stages that powered six of the seven previously flown GSLVs.

Dr. Radhakrishnan said the cryogenic stage had been modified since the April 2010 failure, tested many times and now integrated as the third and upper stage of the rocket at the Sriharikota launch site. He spoke after launching a new programme at the Jawaharlal Nehru Planetarium.

The GSLV, flown first in 2001, has been a partial success. ISRO urgently needs to ready the launcher for putting its communication satellites in earth-fixed or geosynchronous slots in space — or it must pay and use foreign (which have been mostly European Ariane) launch vehicles.

Its older and light-lift launcher, the PSLV, has a neat record after flying 22 times.

The space agency has spared no test or modification on this launcher, which will take up the 2,000-kg GSAT-14 communication satellite: this will replace the experimental Edusat/GSAT-3 which was flown in 2004.

Isro to launch GSAT-4 in August
Bangalore, July b8, 2013, DHNS:

The indigenous cryogenic engine boosting India's Geosynchronous Satellite Launch Vehicle (GSLV) will launch the GSAT-4 satellite in the second week of August.

With an otherwise good track record, earlier attempts to launch the GSLV using the indigenously developed cryogenic engine had caused much embarrassment to the Indian Space Research Organisation (Isro).

Answering a specific question from Deccan Herald, Isro Chairman K Radhakrishnan said on Monday: "The cryogenic engine has been modified, tested and integrated. The GSLV-D5 will launch the GSAT-4 in the second week of August (after August 6)."

The GSAT–4 satellite, with six extended C-band and six Ku-band transponders, is envisaged to enhance communication transponder capacity, in line with the need felt by Isro based on demand.

ISRO's GSLV-D5 slated for August 19 launch
Last Updated: Tuesday, July 23, 2013, 21:52
 
Zee Media Bureau

 Bangalore: Indian Space Research Organisation, ISRO said on Tuesday that it is gearing up to flight-test its GSLV-D5 with indigenous cryogenic engine on August 19.

 ISRO's announcement came after a national team of experts gave the go-ahead. The team included Prof U R Rao and Prof Roddam Narasimha and academics associated with ISRO's rocket programme.

 "The moment we are talking about is August 19th, as a tentative schedule and the time is around 5 PM," said ISRO Chairman K Radhakrishnan. "Vehicle (GSLV or rocket) is already assembled and we have done electrical checks on the vehicle", he said. "We have done nearly 35 ground tests since we had the April 2010 failure, on sub-systems, on the engine and on a similar engine in high altitude conditions".

The space agency designed and developed some components itself and not sourced from outside.

 While other operational rocket, PSLV, has lim itations up to what mass it can handle, India's largest rocket GSLV, having a cryogenic engine, can develop more thrust and can carry heavier communication satellites to a much higher orbit above the earth.

 "Cryogenic route has to be there for the future of the larger communication satellites", Radhakrishnan, also Secretary in the Department of Space, explained, noting that ISRO took up indigenous cryogenic engine programme in 1992.

 He also said the August 19 mission is technically and emotionally important as the previous venture was a failure. "We have to see through. Stakes are very high, seriousness is very high. Entire organisation feels for it. For the last three years, we have been at it".

 ISRO's GSLV-D5 is now slated for launch, with GSAT-14 satellite on board from Sriharikota spaceport more than three years after the failure on flight testing of the indigenous cryogenic stage in GSLV-D3 mission.

 This failure was attributed to the anomalous stopping of Fuel Booster Turbo Pump (FBTP).

 After the unsuccessful April 15, 2010, mission, ISRO conducted extensive failure analysis studies and reviews. ISRO officials said cryogenic stage FBTP was modified as per GSLV-D3 failure analysis committee recommendations and qualification tests carried out.

Radhakrishnan:

 The much-awaited GSLV launch with the indigenous cryogenic engine is scheduled for August 2013. The vehicle assembly is progressing at Sriharikota. The S-139-tonne booster and the four strap-on liquid stage have already been integrated. The integration of the second stage has already commenced. The cryogenic stage is already at Sriharikota and it is going through various preparations.

Are the high altitude tests and other tests of the cryogenic engine over?

This flight stage has an [cryogenic] engine that has already gone through 200 seconds of testing and the stage is getting ready for assembly with the vehicle. In this mission called GSLV-D5, we are launching a communication satellite called GSAT-14, which will weigh about 2,000 kg. It is an important mission.

Over the last three years, after the flight of GSLV-D3 with India's cryogenic stage, which was unsuccessful, we have done a series of ground tests on the sub-systems and the cryogenic engine at the Liquid Propulsion Systems Centre at Mahendragiri [near Nagercoil in Tamil Nadu] after making the necessary design changes in the fuel booster turbo pump [FBTP] and the oxidiser turbo pump. An important test that was devised this year was testing the FBTP in operating conditions at cryogenic temperatures, which was not done in the past. After doing the test, we wanted to see the ignition of the cryogenic engine in high-altitude conditions. It is called a high altitude test [HAT]. This cryogenic engine had not gone through high-altitude tests earlier.

After the last failure in April 2010, we decided to conduct an HAT and we needed a facility for this. An HAT facility was being established for the development of the high-thrust cryogenic engine required for GSLV-Mark III. That facility was ready and we made modifications to that facility to accommodate the GSLV's cryogenic engine and this was done on a war-footing. After the commissioning of the facility, we successfully carried out two simulated high-altitude tests [of the indigenous cryogenic engine] in March and April 2013. The duration was 3.5 seconds, when the ignition of the main engine, the gas generator and the two steering engines were expected to take place in a given sequence. This happened. This test was done with a stand-by engine, called A-4 engine, which was used for the ground tests. So today we have completed the design changes required for the FBTP based on the failure analysis done after the last flight of the indigenous cryogenic engine.

When the GSLV flight with the Russian cryogenic engine failed in December 2010, there was the problem of the connectors snapping.

That was a different issue. I will come to that. During the April 2010 flight with the indigenous cryogenic engine, the cryogenic engine ignited. The steering engines and the gas generator ignited. But the ignition could not be sustained beyond 800 milli-seconds and the FBTP stopped. So an experts' team went into the possible reasons for this failure and it concluded that there were three possibilities. One was related to the clearances of the three bearings of the FBTP, essentially with respect to the differential contraction taking place in the turbo pump because we are using different materials there at cryogenic temperatures. The second possibility was the failure of the casing of the FBTP acquisition. This essentially required a design change in the FBTP. We have taken care of the first and second possibilities.

To take care of the third possibility, we designed and made in India the propellant acquisition system of the hydrogen tank with the necessary volume. The flight engine that we will be using on GSLV-D5 has already gone through 200 seconds of acceptance tests, and after the tests, the necessary inspection and refurbishment have been done.

So, on the one side, based on various flight tests and results, we have taken concerted action. Secondly, we have done extensive test sequences. Thirdly, the flight acceptance test of the engine has been done. Fourth, we have done vigorous inspection and quality control of the components and sub-systems that will go into the cryogenic engine and the stage. In this flight, we are also using indigenously developed polyimide pipes after due qualification. We used to import them earlier from Russia. This has gone through extensive qualification tests. This pipe was developed at the VSSC. This is with respect to the cryogenic stage.

If you look at the last seven GSLV flights, the first flight was aborted. We, however, had a successful flight within a month. But there was a malfunction in the Russian cryogenic stage and the spacecraft had a life of less than two months. The second and third flights of the GSLV successfully placed GSAT-2 and GSAT-3 into orbit. The GSLV-F02 flight in July 2006 failed because one of the strap-on stages stopped functioning after about 55 seconds. The next mission in September 2007 had a problem: the control system of one of the strap-on stages stopped. The vehicle could place INSAT-4C in orbit with an apogee of 30,000 km only [instead of the targeted 36,000 km]. But we were able to recover the spacecraft and place it in the proper orbit. So I will say that it was a partially successful mission.
 In April 2010, GSLV-D3 was flown with an indigenous cryogenic stage. The lower stages functioned extremely well, that is S-139, the four strap-ons and GS-2. The cryogenic stage ignited but the ignition could not be sustained. That was the failure. The seventh flight, that of GSLV F-06 of December 25, 2010, was a failure due to the opening of a shroud in the Russian cryogenic stage, resulting in two connector sets getting disengaged, because of which signals from the equipment bay could not reach the control actuators of the strap-on stage. So the vehicle started losing control after 47 seconds of flight and we had to destroy the vehicle. The failure analysis committee's [FAC] report was published.

We went through an analysis of all the seven GSLV flights and tried to see what the gaps were that we could fill up. In the GSLV-D5 configuration, we are using a heat-shield with a diameter of 3.4 metres and the spacecraft mass is nearly 2,000 kg. We have incorporated a design change in the way the connectors are mounted in the cryogenic stage. The mounting of connectors is redesigned. We have done extensive aero-structural tests of the GSLV. We have also done wind-tunnel tests on the GSLV model.

Where did you do the wind tunnel tests? In Russia?

Both in Russia and at the National Aerospace Laboratories [NAL], Bangalore. We have done structural testing of the modified connector mounting system. We have analysed the test results of the previous seven flights and necessary corrections have been incorporated.

The Mission Readiness Review [MRR] team, headed by Dr B.N. Suresh, former Director, VSSC, and comprising experts from ISRO, and directors and deputy directors of R & D and academic institutions, has been reviewing the work on the indigenous cryogenic engine preparations for the GSLV-D5 mission for nearly two years. The first task was to finalise the configuration of the GSLV-D5 vehicle, incorporating the changes required which are based on our learning from the previous seven flights. The MRR committee and the Flight Readiness Review committee have been monitoring the realisation of the sub-systems and the vehicle stages as well as the results of the tests that have been carried out, and they have already given the clearance for assembling the vehicle. On January 31, 2013, we started stacking the vehicle.

Similarly, in the cryogenic stage, the MRR committee has been overseeing the incorporation of the corrections and the results of the tests before giving clearance to the flight stage. The flight cryogenic stage was moved from Mahendragiri to Sriharikota on May 13, 2013, and the flight preparations are going on.

Indigenous cryogenic engine to power GSLV-D5 on Aug. 19
T. S. Subramanian
 
ISRO expects it will perform smoothly this time; earlier one failed in April 2010

As Geo-synchronous Satellite Launch Vehicle (GSLV-D5) is slated to lift off around 5 p.m. on August 19 from Sriharikota, and various checks showing that the vehicle is in the pink of its health, the mood is one of optimism at the spaceport.

Спойлер

The mission's significance is that GSLV-D5 is powered by an indigenous cryogenic engine and Indian Space Research Organisation (ISRO) has used every expertise available in the country to ensure that the engine performs smoothly this time. The rocket will put India's advanced communication satellite called GSAT-14, weighing 1,980 kg, into orbit.

ISRO Chairman K. Radhakrishnan told The Hindu, "The Mission Readiness Review (MRR) has cleared the vehicle. The integration of the satellite with the launch vehicle has been completed. On August 11, we plan to move the vehicle to the launch pad."

There is enormous focus on this mission, as the GSLV flight with an indigenous cryogenic engine failed in April 2010. The subsequent GSLV flight with a Russian cryogenic stage also failed in December of that year.

S. Ramakrishnan, Director of Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram, brimmed with confidence when asked whether the indigenous cryogenic engine would perform well this time.

"Of course," he said. "We are doing well. We have done all the possible tests. As of now, the [cryogenic] stage health is fine. All checks show that the health of the vehicle is all right."

It would take about an hour for the 49-metre tall rocket, weighing 414 tonnes, to roll on a one-km long rail track from the 17-storey tall VAB (Vehicle Assembly Building) to the launch pad on August 11. A platform with wheels, on which the three-stage vehicle was stacked up inside the VAB, would ferry the rocket to the launch pad.

Mr. Ramakrishnan said, "Once we go to the launch pad, we will connect the umbilicals. During the final countdown, which will be of the order of 35 hours, the rocket will be filled with propellants. The satellite has already been filled with propellants."

Positive results

M.C. Dathan, Director of the Liquid Propulsion Systems Centre (LPSC), called the August 6 MRR "a wonderful meeting," because "there was no apprehension or anxiety" excepting a couple of minor issues. Tests on the vehicle yielded positive results.

Mr. Dathan asserted "we have made use of every possible expertise available in the country" to ensure that the indigenous cryogenic engine performed flawlessly. This included expertise from the academic institutions, and research and development centres.

In April 2010, the indigenous cryogenic engine ignited; the steering engine and the gas generator ignited, but the ignition could not be sustained beyond 800 milliseconds and the fuel booster turbo pump (FBTP) stopped.

Dr. Radhakrishnan elaborated on the steps taken to address the inadequacies of the 2010 flight. He said, "Over the last three years... we have done a series of ground tests on the sub-systems and the cryogenic engine" at the LPSC at Mahendragiri, Tamil Nadu, "after making the necessary design changes in the FBTP and the oxidiser turbo pump." An important test done this year was testing the FBTP in operating conditions at cryogenic temperatures. Ignition of the engine in high-altitude conditions [simulating the vacuum in space] was also done. The duration of this test was 3.5 seconds, when the ignition of the main engine, the gas generator and the two steering engines should take place in a given sequence. "This happened."
