On launch of two Geosynchronous Satellite Launch Vehicle (GSLVs) and Polar Satellite Launch Vehicle (PSLV) this fiscal, Radhakrishnan said ISRO has studied the reasons for the failure in 2010. "Now GSLV will undergo an endurance test of 1,000 seconds and a vacuum test at a special facility at the Liquid Propellant System Centre at Mahendragiri in Tamil Nadu,
where a Rs 300 crore facility for vacuum test has been made," he said.

"Once we get the green signal from the Ground Testing Team, we would be ready for the GSLV launch," he said.

PS Veeraraghavan, Director, Vikram Sarabhai Space Centre, who was present, said ISRO will launch a low cost communication satellite GSAT-14 on board GSLV D5 in September/October 2012.

In a major step, ISRO today successfully tested the indigenous cryogenic engine to be used to propel the country's Geosynchronous Satellite Launch Vehicle.

The test was conducted at the Liquid Propulsion Systems Centre at Mahendragiri in Tamil Nadu's Tirunelveli district.

"The acceptance test of the indigenous cryogenic engine for the forthcoming GSLV-D5 flight was conducted successfully for 200 seconds at 17:10 hrs...," an ISRO statement said.

"The performance of the engine was as predicted," it said.

The maiden flight test of the indigenous cryogenic stage onboard GSLV-D3 failed in May 2010 after it developed a snag and the rocket plunged into the sea minutes after lift-off.

ISRO chief K Radhakrishnan had said last month that GSLV would undergo two more tests at the Mahendragiri facility.

He had also said ISRO was planning a GSLV launch with Indian cryogenic engine during September-October.

ISRO plans to fly two GSLV rockets at an interval of six months with the third one meant for the Chandrayaan-2 moon mission.

Agreeing that ISRO normally do not launch any rockets during that period, Veeraraghavan said if the weather is conducive the rocket could be sent up.

He said ISRO is also planning to launch GSAT-14 a small communication satellite that is considered as the replacement for India's the education satellite Edusat, by this December or January next year using its heavier rocket Geosynchronous Satellite Launch Vehicle (GSLV). The spacecraft will carry Ka band beacons, which are planned to be used to carry out studies related to rain and atmospheric effects on Ka band satellite communication links in Indian region.

ISRO will be flying the GSLV rocket this time with its own cryogenic engine. This will be the second GSLV rocket to fly with indigenous cryogenic engine. The first GSLV rocket that flew with indigenous cryogenic engine in 2010 was a failure.

" Following this, the launch of Saral navigational satellite with PSLV C20 has been scheduled to take place on December 12.

 The assembly of the satellite will be done in 25 days at Sriharikota, he said.

 "GSAT 7 and INSAT 3 satellites have undergone successful space simulation tests and are going to be launched next year.

 The much-awaited GSLV D5 is in the engineering stage.

 It could be launched in January or February next year.

 The GSAT 40 (правильно читать 14) communication satellite will also be ready," Radhakrishnan said.

Successful ignition of indigenous cryogenic engine
Special Correspondent

Successful ignition of an indigenous cryogenic engine on Wednesday at Mahendragiri in Tamil Nadu's Kanyakumari district, in conditions simulating the high altitude atmosphere, has boosted the confidence of the Indian Space Research Organisation (ISRO) to go ahead with the launch of a Geo-synchronous Satellite Launch Vehicle (GSLV-D5) in July.

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.

Fresh GSLV launch attempt in July
Amitabh Sinha : New Delhi, Wed Apr 10 2013, 03:48 hrs

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.

High altitude test of cryogenic engine successful; ISRO to launch GSLV-D5 in July
Laxmi Ajai Prasanna, TNN | Apr 25, 2013, 02.46 AM IST

THIRUVANANTHAPURAM: 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.

BANGALORE, April 27, 2013
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.

GSLV D5 launch planned in July: Union Minister V Narayanasamy
Thursday, May 16, 2013, 20:47 IST | Place: Chennai | Agency: PTI

ISRO's last two attempts to launch satellites were a failure.

India plans to undertake launch of GSLV D5, fitted with indigenous cryogenic engine and carrying communication satellite GSAT-14, in July, Union Minister V Narayanasamy said on Thursday.

"Russia had denied us the cryogenic engine. Our scientists are working hard for indigenous engine. In July, India will launch GSAT-14 from the spaceport in Sriharikota," the Minister of State for PMO told a convocation in Chennai.

GSAT-14 satellite with six extended C band and 6 Ku band transponders envisages enhancing the communication transponder capacity, ISRO sources said.

ISRO's last two attempts to launch satellites were a failure. GSLV-F06 carrying satellite GSAT-5P on December 25, 2010 and GSLV-D3 carrying satellite GSAT-4 on April 15, 2010 were unsuccessful.

ISRO sources said preparations are on at the second launch pad at the spaceport of Sriharikota for the launch of GSLV-D5 (Geosynchronous Satellite Launch Vehicle-Development flight 5) in August.

GSLV-D5 aerodynamic characterisation has been revisited following the back-to-back failure of GSLV flights - one with indigenous cryogenic engine and another with a Russian-made one in 2010.

Force measurements, steady and unsteady pressure measurements and aero elastic tests have already been conducted using wind tunnel models at National Aerospace Laboratory, Bangalore and Glavkosmos, Russia.

Computational fluid dynamics simulations have been carried out in-house for incremental effects on protrusion, overall aerodynamic load distribution and distribution on protrusions, according to ISRO.

GSLV-D5 would carry GSAT-14 satellite with six extended C band and six Ku band transponders, envisaged to enhance communication transponder capacity.

The satellite employs the standard 2,000 Kg class bus (I-2K) with a power handling capability of around 2.5 KW and a lift-off mass of 1,980 kg, the space agency added.

ISRO's GSLV Mk-2 Launcher Return to Flight Test in August

 ISRO hopes to resume its GLSV medium launcher operations with the return to flight test of GSLV D05 fitted with the indigenous Cryogenic Upper Stage (CUS) and carrying the communication satellite GSAT-14, tentatively on August 6, 2013.
ISRO's 2012 Annual Report had stated that the next two GSLV missions would be conducted as developmental flights.
GSLV-D05 will be test flown with a 3.4-m payload fairing and indigenous CUS. A follow-up test flight, GSLV-D05, will be conducted with a 4-m payload fairing and indigenous CUS.
ISRO had earlier fitted the 4-m composite payload fairing for the first time on GSLV F06 for its December 2010 launch. The launch failed because a group of 10 connectors located at the bottom portion of the Russian Cryogenic Upper Stage snapped because of aerodynamic loads induced distortion in the fairing, cutting off command signals from the onboard computer in the Equipment Bay (located near the top of the vehicle) to the control electronics of the four L40 Strap-ons of the First Stage.
The launch failure led to the grounding of the GLSV launcher.
A Failure Analysis Committee recommended strengthening of the shroud.
All GSLV flights before GSLV F06 featured a 3.4-m aluminium payload fairing.
ISRO's focus in the GSLV D05 test in August would be on proving the indigenous CUS which failed during its maiden test on GLSV-D3 on April 15, 2010
The failure was attributed to a malfunction of the booster pump of the indigenous CUS.
On October 12, 2011, S.Ramakrishnan, director of ISRO's Liquid Propulsion Systems Centre (LPSC) said the agency had identified and fixed the reasons for the failure of the first engine during the flight of GSLV-D3.
"We have studied the design of booster pumps and redesigned it. The computer simulation was done and validated." he said.
The booster pump has been successfully hot tested twice in the past three months at the newly-built high altitude test facility (HAT) at ISRO's Liquid Propulsion Systems Centre (LPSC) at Mahendragiri.
LPSC director MC Dathan told TOI on Friday, June 28 that a mission readiness meet for GSLV-D05 launch was held on Thursday.
Dathan added, "We are very confident after the repeat successful High Altitude Tests in the last three months. Yet we are anxious about the indigenous cryogenic stage which was moved from LPSC Mahendragiri on May 13, it is being integrated with the vehicle at Sriharikota and further checks will be completed within 45 days. It will be ready by July end and tentatively the launch is set for August 6."
If the two missions are successful, the GSLV program will be considered as being back on track and the launcher will once again be used to launch high value payloads like Chandrayaan 2, which could be launched in 2014.
