IANS | May 11, 2012, 11.08PM IST

BANGALORE: The Indian space agency will Saturday conduct a crucial test on an indigenously built cryogenic engine for launching its heavier rockets from its spaceport, a top official said Friday.

"The cryogenic acceptance test will take place Saturday in our Liquid Propulsion Systems Centre at Mahendragiri in Tamil Nadu. If it succeeds, we will use the cryogenic stage in the geostationary satellite launch vehicle (GSLV) rocket later this year," state-run Indian Space Research Organisation (ISRO) chairman K. Radhakrishnan told reporters here.

Th espace agency's attempt to use its first cryogenic engine April 15, 2010 to launch a communication satellite on board a GSLV was aborted as the heavy rocket plunged into the sea within minutes after blast-off from its Sriharikota spaceport, about 80 km north-east of Chennai.

"We have learnt a lot from the previous attempt and rectified the errors that caused the failure two years ago," Radhakrishnan admitted.

A cryogenic engine is a rocket motor that is fired by a mixture of liquid fuels (oxidiser) such as hydrogen and oxygen at very low temperatures of 20 degrees Kelvin and 90 degree Kelvin.

Buoyed by the success of its polar satellite launch vehicle (PSLV-C19) putting into a higher orbit its microwave radar imaging satellite (Risat-1) April 26, the space agency has drawn up an ambitious plan to launch a series of space missions over the next two years using a combination of lighter (PSLV) and heavier (GSLV) rockets, including an experimental flight of GSLV-Mark III.

"We have designed GSLV-Mark III to be self-reliant in launching four-five tonne communication satellites in the INSAT-4 series. The next generation rocket will also enhance our capability to be a competitive player in the multi-billion dollar commercial launch market," Radhakrishnan asserted on the occasion of the space agency's satellite centre (ISAC) herecompleting four decades (Ruby Year) of service.

The advanced rocket will have a multi-mission launch capability for geo-synchronous transfer orbit (GTO), low earth orbit (lEO), polar and intermediate circular orbits.

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.

ЦитироватьGSLV-Mk III experimental flight in 2014: ISRO chairman Radhakrishnan
India, Posted on Apr 03, 2013 at 11:24pm IST
Press Trust of India

New Delhi: India plans to launch a next generation rocket to put heavier satellites and more astronauts into outer space within a year, a top official said on Wednesday. "The first experimental flight of the GSLV Mark III will take place one year from now," K Radhakrishnan, Chairman, Indian Space Research Organisation told the Annual General Meeting of the Confederation of Indian Industry in New Delhi.

The new rocket, which can put a four tonne satellite in orbit, will help Antrix Corporation, ISRO's commercial arm, to offer cheapest space launches in the niche market. The regular GSLV can put 2.2 tonne satellites in orbit.

The GSLV Mark III will enable ISRO launch heavier satellites, an activity for which it has to turn to foreign launch vehicles like Arianspace, based in Kourou in French Guiana. The GSLV Mark III will also help ISRO put more Indians in space at one go.

GSLV Mark III is designed to be a three-stage 42.4 m tall vehicle, with a lift off weight of 630 tonnes. First stage comprises two identical S200 Large Solid Booster with 200 tonne solid propellant, that are strapped on to the second stage, the L110 re-startable liquid stage.

The third stage is the cryogenic upper stage loaded with 25 tonnes of propellant. The large payload fairing measures five meters in diameter and can accommodate a payload volume of 100 cubic meters.

ЦитироватьIndia to test fly heaviest rocket next year: ISRO

India's heaviest rocket ever is expected to take to the sky next January on an experimental flight whose later versions could be used to send humans on space missions.

The mainstay of the Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III) would be to put in orbit communication satellites weighing between four and five tonnes, thus packing more transponders per launch.

"We are targetting an experimental flight of GSLV-Mk III in January 2014," Indian Space Research Organisation (ISRO) Chairman K Radhakrishnan told reporters after a public lecture at the Indian National Science Academy (INSA) here.

This will also be a first time that ISRO scientists would undertake an experimental flight of a launch vehicle which would fall into the sea after reaching a height of 120 km.

"We have been simulating the flight using computers. But there are certain tests that cannot be carried out on the ground. We will test the rocket in a cost effective manner," GSLV-Mk III's project director S Somnath said.

He said ISRO engineers have planned to take some 2,000 measurements during the experimental flight of the GSLV-Mk III, which would weigh 640 tonnes at lift-off, making it the heaviest rocket built in the country.

"All the 2000 measurements during the flight would be telemetered down to the ground station. We will analyse them. This will enable us to have full knowledge of the flight," Somnath said.

The new rocket, which can put a four tonne satellite in orbit, will help Antrix Corporation, ISRO's commercial arm, to offer cheapest space launches in the niche market.

ЦитироватьIndia's first manned space flight trial in 2015
New Delhi, April 9, 2013, DHNS:

The first flight of ISRO's new and powerful rocket that will be able to carry an Indian to space, is expected to take place by the middle of 2015.

Known as the Geostationary satellite launch vehicle (GSLV) Mark-III, this is the heavy-duty rocket, which Indian Space Research Organisation (ISRO) will use to send an Indian astronaut to the space. Doing the same with commercial foreign rockets, would be very expensive.

"GSLV Mk-III will have a payload of 6-10 tonnes and can take an Indian astronaut to a low earth orbit," ISRO chairman K Radhakrishnan said at the Indian National Science Academy here on Tuesday.

Sending a man to the moon is not on ISRO's immediate agenda because the rocket has to carry a load of 35 tonnes up to the lunar orbit.

"For comparison, Chandrayan-I weighs only 1.8 tonnes. Such kind of up-scaling in rocket's capability is needed. The cost for such a mission will be very high," he said.
But a manned space flight to a low earth orbit (upwards of 160 km to few hundreds of km) is on the space agency's radar. Except USA'a Apollo missions to moon, all other manned space flights took place in these zones. The international space station moves at an altitude between 330 and 435 km.

However, because of a series of failure in the GSLV flights, space scientists have now planned to do an experimental test flight of the GSLV Mk-III in, January 2014 without the crucial cryogenic upper stage, which is being developed indigenously.
The experimental flight will have a full-fledged GSLV with strap on boosters without the cryogenic engine.

It will fly up to an altitude of 120 km after which it will take a parabolic path and dive in the Bay of Bengal.

The flight will generate crucial aerodynamics data which ISRO scientists will use while designing the rocket for first manned space flight.

"We have received permissions from the government for two developmental flights of GSLV with indigenous cryogenic engine. The first developmental flight is expected in 18 months after the experimental flight in January, 2014," said S Somnath, project director of GSLV Mk-III programme at Vikram Sarabhai Space Centre, Thiruvananthapuram.

The indigenous cryogenic engine, which failed in its first flight in 2010, will now be put to test again in July, when an older generation GSLV (Mk-II) is scheduled to be launched. Capable of carrying a payload up to 2.5 tonnes, GSLV Mk-II can reduce India's reliance on French ArianeSpace rockets to take INSAT class satellites to the 36,000 km orbit.

"GLSV Mk-III has a completely different architecture than Mk-II. It carries twice as much fuel and the thrust is double than that of Mk-II. We need both versions of GSLV to save our foreign exchange," Somnath told Deccan Herald.

ISRO Unified Launch Vehicle (ULV)
http://forum.nasaspaceflight.com/index.php?topic=31827.0

ULV configurations (ULVs long term goal is to replace PSLV, GSLV & LVM MK3 with a LV having common core stages (semi-cryo stage (SC-160) & cryo stage (C25)) and solid boosters with variable fuel loading.

ЦитироватьI am guessing that the large core is kerosene powered, and there is a small LH2 powered upper stage. If it's the reverse, that would be sad.

Yes, the large core/first stage is kerosene + LOX powered with 2000 kn thrust engine (1-2 engine, nos not confirmed). The engine is under development. Second stage would be LH2+LOX.
Go MSL!

ЦитироватьI heard that it will be a passive flight of GSLV–Mark III. What is a passive flight?

Radhakrishnan:
It will be a passive cryo. You have the configuration of GSLV–Mark III, which comprises two solid strap-ons, S-200 with a propellant loading of 200 tonnes each; the liquid core stage which has a dual engine; and the high-thrust cryogenic stage [above it]. We call it C-25. That is, it will carry 25 tonnes of cryogenic propellants. The S-200 solid stage has already been qualified. One of the critical requirements is that the performance of the two strap-ons should be identical. The liquid stage has been qualified on the ground. Avionics and other sub-systems are ready. We are waiting for the completion of the development of the cryogenic engine and the stage.
 One of the essential requirements is the atmospheric characterisation of this launch vehicle configuration. So without waiting for the cryogenic engine and the stage to be ready, we are going ahead with this experimental mission where we will have S-200 strap-ons and the L-110 [110 tonnes of liquid propellants] stages and the cryogenic stage which [the cryogenic engine] will not ignite. It will not give any acceleration to the vehicle. We will get nearly 5 km per second provided by the solid and liquid stages. It will be a sub-orbital flight. The most important part of it is that it will go through the atmospheric phase and we will make all the measurements in flight required to characterise the vehicle and its performance. This is scheduled for January 2014. This is going to be a major milestone in the GSLV–Mark III development.
...
 The immediate task on hand is the development of GSLV–Mark III. Its experimental mission with a passive cryogenic stage will be in January 2014. After three years, a developmental flight with an active cryogenic stage will take place.

 So the first GSLV–Mark III flight will be in 2017.

Radhakrishnan:
Yes. We should have the testing of the engine and the stage conducted.

ISRO Human Space Flight Program (HSP)
 
 
As a natural progression of its endeavors, ISRO has decided to start a Human Space flight program. It has been decided that the entire program will be split into following three different phases:
    [/li]
  • First phase: design, development and performance demonstration of critical technologies leading to manned space missions.
  • Second phase and third phase would establish the necessary infrastructure, do qualification tests including flight testing with test vehicles, PSLV, GSLV and GSLV Mk III and finally demonstrate the first Indian Human Spaceflight.
In the first phase, during the 12th plan period (2012-2018 ), ISRO has proposed to develop and demonstrate all the major technologies and infrastructure critical for Human Spaceflight Program (HSP) including pad abort test, Orbital Vehicle (OV), Crew Escape System (CES), Environmental Control and Life Support Systems (ECLSS) & Flight Suit, Human rating of Launch Vehicle (LVM3) and realizing essential facilities including third launch pad for the development and flight testing of these systems. Mission and configuration studies and technical developmental activities will also be initiated for the Human Lunar Missions.
 
 
The first major-milestone activity is "pad abort test" that is planned to demonstrate the performance of crew escape system (CES). This test will play a vital role in establishing the critical
abort maneuver of the CES which has to take the crew module (CM) to an altitude of about 2 km and range of about 2 km from the launch pad. The objectives of this pad abort test are:
    [/li]
  • Verify the performance / functioning of various motors / systems of CES.
  • Verify the capability of CES to take CM to the required altitude (~ 2 km) & range (~ 2 km).
  • Demonstrate the deceleration & floatation capability of parachute and Crew Module.
  • Validate the crew module recovery from sea.
Work on the Orbital vehicle is progressing well. ISRO has built an  ergonomic model of crew module for study and is conducting plasma wind tunnel tests on scaled crew module models. ISRO has decided to convert the PSLV PS4 (4th stage) into a service module for the OV. 
 

Ergonomic model of ISRO crew module.

For meeting the requirements of HSP, human rating of GSLV MK III or LVM3 will also be initiated in the 12th plan period. The work will involve the following:
    [/li]
  • Redesign of vehicle structures including propellant tanks and motor cases if necessary.
  • Re-qualification tests including stage functional tests of S200, L110 and C25.
  • Intelligent systems to monitor and identify the imminent failure of systems are to be developed.
  • Redundancy schemes in all the avionics, control systems, pyro systems and mechanisms are to be re-looked and re-qualified.
  • Additional facilities for structural test are to be developed for conducting these tests.
