Одно я знаю, что ЖРД меньше отравляет атмосферу по сравнению.

Тут вы сильно заблуждаетесь. В выхлопе ТТРД полно соляной кислоты и хлорорганики, в то время, как у ЖРД проценты (к полному выхлопу) окислов азота, в основном же молекулярный азот и вода.

Towards self-reliance in launch vehicle technology
T. S. Subramanian

GSLV Mk-III, is the most powerful rocket to be built by ISRO, will make India totally self-reliant in launch vehicle technology for launching INSAT class of communication satellites which are now being put in orbit for India by the European launcher Ariane-5.

"Towards sustained self-reliance in accessing space, GSLV Mk-III, the next generation launch vehicle," announces a stylish poster on India's Geo-synchronous Satellite Launch Vehicle Mark III, which is currently under development.

The poster, along with a model of the GSLV Mk-III, was prominently displayed in the Indian Space Research Organisation's (ISRO) pavilion, "Pride of India," during the Indian Science Congress held recently at Thiruvananthapuram.

The GSLV Mk-III will make India totally self-reliant in launch vehicle technology for launching INSAT class of communication satellites which are now being put in orbit for India by the European launcher Ariane-5.

In the fourth week of this month, the ISRO will cross a milestone in its efforts to develop this aerial powerhouse called the GSLV Mk-III when one of its two gigantic strap-on booster motors, S-200, erupts into life and fires for about 130 seconds. The motor will fire at the massive new test facility built at the Satish Dhawan Space Centre (SDSC), Sriharikota. The motor is called S-200 because it is powered by 200 tonnes of solid propellants.

The Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, has designed S-200, and propellant casting has been done in a newly built plant at Sriharikota. The final preparation for ground-testing of the motor is progressing at Sriharikota and test readiness is being reviewed by the Test Authorisation Board chaired by SDSC Director M.C. Dathan.

In February first week, the ISRO will cross another milestone when the GSLV Mk-III's core stage (L-110), powered by 110 tonnes of liquid propellants, fires for about 200 seconds at the huge test stand at the Liquid Propulsion Systems Centre (LPSC) at Mahendragiri near Nagercoil in Tamil Nadu.

Short-duration test

A test for 15 seconds will be done to validate the performance of the engine and the associated ground facilities before the long-duration test is conducted for 200 seconds. The final preparations for testing the L-110 stage are on at Mahendragiri under the guidance of LPSC Director M.K.G. Nair.

Sub-systems are getting ready for undergoing tests at the same facility for the upper cryogenic stage, which will be fuelled by 25 tonnes of liquid oxygen and liquid hydrogen.

If everything goes on schedule, the first flight of the GSLV Mk-III will take place by the end of 2011. It is the most powerful rocket to be built by the ISRO, weighing 630 tonnes and 43.5 metres tall. It can put a satellite weighing four tonnes in a geo-synchronous transfer orbit with a perigee of about 200 km and an apogee of 36,000 km. It can put a satellite weighing 10 tonnes in a near-earth orbit at an altitude of about 300 km.

It has three stages. The two boosters, S-200, form the first stage. The boosters hug the core/second liquid stage. Above this liquid stage is the cryogenic stage.

"S-200 stage is the third largest stage in the world. Preparations are on for the first static test of the S-200 motor at Sriharikota. It will be a milestone in the GSLV Mk-III's development," said VSSC Director P.S. Veeraraghavan. S-200 is the third largest booster after the NASA Space Shuttle and Arianespace Ariane-5's boosters.

According to N. Narayana Moorthy, Project Director, GSLV Mk-III, the ISRO executed a massive programme of building the infrastructure needed for the project at Sriharikota, Mahendragiri and in Thiruvananthapuram. Out of Rs. 2,500 crore allocated to the project, Rs. 1,600 crore was earmarked for building infrastructure including facilities for assembling and testing the solid, liquid and cryogenic engines and their stages, and integration halls at Sriharikota, Mahendragiri and in Thiruvananthapuram. A big plant for manufacturing the solid propellants needed for S-200 boosters has come up at Sriharikota.

"The ISRO has built big facilities in the launch complex at Sriharikota for handling and integration of the GSLV Mk-III. These include erection of a new mobile launch pedestal since the core vehicle's diameter is four metres," said Mr. Narayana Moorthy. Major facilities have come up at the VSSC and Sriharikota for structural testing of different hardware including propellant tanks and light alloy structures.

"We have completed building most of the infrastructure and we are starting the testing phase. The launch schedule will depend on the outcome of the ground tests," said Mr. Narayana Moorthy.

GSLV Mk-III's motor S-200 will be tested in the last week of January If everything goes on schedule, the first flight will take place by 2011-end

Trouble with a new cryogenic engine is delaying India's plans to debut an updated all-Indian version of its Geosynchronous Satellite Launch Vehicle, the most powerful rocket in the country's inventory.

The GSLV has flown five times since 2001 with a Russian hydrogen-fueled third stage originally built for the Proton rocket. The Russian third stage is blamed for two minor mishaps in 2001 and 2007 that resulted in an underperformance of the rocket, leaving its payloads in slightly different orbits than planned.

Первая, стартовой массой 3075 т, несет разгонную ступень C60 массой 67 т (включая 60 т криогенного топлива) и лунный модуль (17 т). Ракета будет оснащена криогенной первой ступенью C800 (800 т топлива), окруженной восемью твердотопливными ускорителями S230 (230 т топлива в каждом).
Вторая РН, стартовой массой 1690 т, должна вывести на орбиту служебный (25 т) и командный (6 т) модули лунного корабля. Эта ракета аналогична первой, но оснащена лишь четырьмя ускорителями. В остальном сценарий напоминает миссию Saturn – Apollo".

Presentation on the Indian space program given at the recent IAC2009 meeting in South Korea:

The plan of India to land on the Moon in 2025

During the 60th IAC (International Astronautical Congress) in Daejeon (South Korea), a plenary session (15 October 2009, a.m.) was dedicated to Human Lunar Exploration. Dr. V. Admurthy, Associate Director, ISRO VSSC (Vikram Sarabhai Space Center), presented the ambitions of India in the exploration of the Moon, Mars, of asteroids and comets. During his 6-minute speech, he spoke about the preparation of a probe to explore the Toutatis asteroid to be launched on 20 October 2015 and will fly by Toutatis in August 2020 when it comes close to our planet. He described the strategy of India's Department of Space to achieve manned spaceflight around the Earth and to the lunar surface! In his conclusion, he insisted on the economical, architectural and ethical aspects of manned lunar missions, on the technological spin-offs and the international character of such an venture. India affirms its readiness to contribute to this challenging odyssey.

On a slide (see images below), Theo Pirard, who attended the conference, discovered the projected plan of the Indian manned Mission on the Moon, which is the result of recent feasibility studies made by ISRO. This plan offers some similarities with the US Constellation programme for the return to the Moon but no date could be announced, because of lack of money.

Two new super-boosters, derived from the next GSLV MkIII launcher, have to be developed by India for operations from Sriharikota Island:

- The 3.075-t rocket, consisting of 8 S230 (solid boosters of 230 t) and SC800 (core stage with semi-cryogenic engines of 2000 kN and 800 t of cryogenic propellant) as the 1st stage and of C60 (1 engine and 60 t of cryogenic propellant) as the 2nd /upper stage) will put into low earth orbit the EDS (Earth Departing Stage) of 67 t with the LM (Lunar Module) of 17 t.

- The 1.690-t rocket, consisting of 4 S230 (solid boosters of 230 t) and SC500 (core stage with semi-cryogenic engines of 2000 kN and 500 t of cryogenic propellant) as the fist stage and of C60 (1 engine and 60 t of cryogenic propellant) as the upper stage will launch the manned CM (Crew Module) of 6 t with its SM (Service Module) of 25 t.

The EDS has to send in trans-lunar trajectory a payload of around 48-50 t. India is starting the technological R & D efforts for the semi-cryogenic engine of 2000-KN thrust, which represents a great challenge for its future in space.

You can find the video of his presentation on YouTube (minute 16.00 -22.10) on the site http://www.iafastro.com/index.html?title=IAC2009_Plenary_7.

There is also a description of the Russian project to visit the Moon with manned spaceships and a short presentation of the Chinese Space Programme, including the next Chang'E missions of lunar exploration.

Flight-Testing Of Cryogenic Stage Of GSLV In April

Indian Space Research Organisation Chairman K. Radhakrishnan has said the flight- testing of the indigenous cryogenic stage of the GSLV D3 would be conducted in April.

Talking to reporters after receiving the Doctor of Science (Honoris Causa) at the fifth convocation of SRM University here, Radhakrishnan said: The vehicle would carry GAST-4, a communication satellite. Though we had several GSLV flights, we were using the Russian cryogenic stages."

"As far as cryogenic engine and stages were concerned, ISRO had tested engines for 7,500 seconds," he added.

The country's first unmanned lunar mission, Chandrayaan, was launched in late October, 2008.

The second unmanned project, Chandrayaan-II, will be launched in the first quarter of 2013 - a prelude to the manned space mission.

India is emerging as a major player in the multi-billion dollar space research and space missions.

The first flight testing of GSLV MK-III rocket, which will put heavier satellites in space, is likely to be carried out in April, the ISRO today said.

ISRO chairman K Radhakrishnan said scientists are working hard in developing the satellite and expressed hope that its first flight testing would take place in April.

Addressing nearly 650 delegates at the 16th National Space Science Symposium (NSSS) hosted by the Saurashtra University here, Radhakrishnan said human presence in solar system is the next logical step in space research, which is a very challenging job because of high expectations.

On January 24, ISRO had successfully conducted the static testing of GSLV Mk III's Solid Propellant Booster Rocket Stage, S200, at the Satish Dhawan Space Centre in Sriharikota. The testing of the liquid stage is expected later this month.

He said it is ISRO's dream to send human beings to the moon. "We are pursuing this dream."

Gearing up for future

Mon, Feb 15 01:51 AM

Scientists at Indian Space Research Organisation (ISRO) are all fired up these days. Buoyed by the recent success of the ground test of the S-200 solid propellant rocket motor for the geosynchronous satellite launch vehicle mark III (GSLV-Mk III)—the third largest solid propellant boosters in the world after the US Space Shuttle's booster and Europe's Ariane and the largest solid rocket booster in Asia—they have reached a milestone in space technology.

The development is significant as the S200 forms a key component of the GSLV-Mk III launch vehicle that ISRO is developing and is currently under advanced stage of development for launching 4-tonne class of heavy communication satellites. More specifically, ISRO is developing the GSLV-Mk III to enhance the capability of the country to be a competitive player in the multi-million dollar commercial launch market. It will also allow India to become less dependent on foreign rockets for heavy lifting.

India is keenly developing its GSLV technology to enhance indigenous launching capabilities for heavy satellites of four tonne category. Unlike the polar satellite launch vehicle (PSLV), which is used to put lighter satellites into orbit 600 to 800 km above the earth's surface, the GSLV is used to put heavier satellites into the geosynchronous orbit which is 36,000 km above the earth's surface. Hence, GSLV is a much bigger and more powerful rocket. ISRO is also considering usage of GSLV for the Chandrayaan-II mission scheduled for 2012. Earlier, ISRO used PSLV to launch Chandrayaan-I.

Confidence of ISRO scientists is already high as the US space agency NASA signed an agreement with the Indian space agency to use data from Indian satellite Oceansat-2, for various American agencies for research activities, including weather forecasting. Launched on September 23, 2009 using the PSLV from Sriharikota, Oceansat-2 is designed to provide service continuity for operational users of the ocean colour monitor (OCM) instrument on Oceansat-1.

ISRO chief K Radhakrishnan says, "GSLV-Mk III is expected in the coming years. And a major milestone in the development is going to be the static testing of the systems." He adds, "We could realise the world's third largest propellant boosters H200 with 200 tonne of propellants mixed in India, in a plant which is mostly automatic. It is located in Sriharikota with our own technology and the ingredients based on our technology coming from the Indian industry ."

ISRO officials inform that GSLV-Mk III is conceived and designed to make the space agency fully self reliant in launching heavier communication satellites of INSAT-4 class, which weigh 4,500 to 5,000 kg. The vehicle envisages multi-mission launch capability for geostationary transfer orbit (GTO), low earth orbit (LEO), polar and intermediate circular orbits.

S200 solid booster contains 200 tonne of solid propellant in three segments. The motor measures 22 meter long and 3.2 meter in diameter. The design, development and successful realisation of S200 solid booster were a pure indigenous effort involving Vikram Sarabhai Space Centre, Thiruvananthapuram and Satish Shawan Space Centre (SDSC) at Sriharikota with the participation of Indian companies. The S200 solid booster derived its heritage from the solid boosters developed earlier for the ISRO launch vehicle programme. The preparation and casting of S200 solid booster segments were carried out at the newly established solid propellant plant (SPP) at SDSC, Sriharikota.

During the test, the S200 booster was fired for 130 seconds and generated a peak thrust of about 500 tonne. The performance of the booster was exactly as predicted, ISRO officials inform. Nearly 600 health parameters were monitored during the test and the initial data indicated normal performance.

The GSLV-Mk III is a three-stage satellite launch vehicle with a 110 tonne core liquid propellant stage (L-110) and a strap-on stage with two solid propellant motors, each with 200 tonne propellant (S-200). Once operational, GSLV Mk-III will have a lift-off weight of about 629 tonne. In place of small solid strap-on boosters used in the PSLV, the GSLV uses four liquid boosters that are derived from the PSLV second stage. The same solid first stage and liquid second stage are carried over from the PSLV. The third stage is a cryogenic hydrogen/oxygen upper stage.

The development work on GSLV-Mk III began in October 2002. ISRO executed a massive programme of building the infrastructure needed for the project at Sriharikota, Mahendragiri and in Thiruvananthapuram. Out of Rs 2,500 crore allocated to the project, Rs. 1,600 crore was earmarked for building infrastructure including facilities for assembling and testing the solid, liquid and cryogenic engines and their stages, and integration halls at Sriharikota, Mahendragiri and in Thiruvananthapuram. A facility for manufacturing the solid propellants needed for S-200 boosters has also been set up at Sriharikota.

"ISRO has built big facilities in the launch complex at Sriharikota for handling and integration of the GSLV Mk-III. These include erection of a new mobile launch pedestal since the core vehicle's diameter is four metres," say ISRO officials. Major facilities have also been built for structural testing of different hardware, including propellant tanks and light alloy structures.

In 2008, the government gave the go ahead to ISRO to develop an indigenous semi-cryogenic engine that would power the core stages of future Indian launch vehicles. The project has been one of the priorities of ISRO and it plans to complete the development phase of the project by 2012. India has been importing the cryogenic engines from Russia since 1991. So far, India has launched five GSLV rockets. But now ISRO has developed its own cryogenic engines and all the tests have been completed successfully.

ISRO plans to replace the core stage of GSLV-Mk III with a more powerful engine. The new core stage will be powered by a single, possibly ground-ignited semi cryogenic engine with the propellant mass being similar to the present 110 tonne. This change will increase the capability of Mk-III to about 6 tonne to GTO and about 15 tonne to LEO. Upper stage upgrades could further increase the GTO performance.

The timeline of these upgrades would depend on timeline of development of the GSLV-Mk III programme. By current estimates, this will happen no sooner than 2015 possibly even later. But testing these new technologies on GSLV-Mk III could act as a testing ground for the future family of launch vehicles. The flight testing of the indigenous cryogenic stage of the GSLV D3 would be conducted in April. The vehicle would carry GAST-4, a communication satellite.

ISRO scientists are developing next generation rockets capable of carrying more astronauts, and orbiting heavier satellites. Senior scientists at the country's space agency say the GSLV Mk III will ultimately make the country self-sufficient in launching the entire range of satellites. "If everything goes through successfully, we can attempt a launch by 2011 beginning," ISRO officials inform.

Truly, Indian rocket scientists are gearing up for future missions.

Static testing of L110 liquid core stage of GSLV- MkIII launch vehicle conducted

Indian Space Research Organisation conducted the static test of its liquid core stage (L110) of GSLV Mk III launch vehicle, for 150 seconds at its Liquid Propulsion Systems Centre (LPSC) test facility at Mahendragiri at 16:00 hrs yesterday (March 5, 2010).

While the test was originally targeted for 200 seconds it was stopped at 150 seconds since a deviation in one of the parameters was observed. About 500 important parameters were monitored during the static test. The next static test for 200 seconds will be conducted after analysis of this data.

GSLV Mk III launch vehicle is being developed for launching 4 tonne class of satellites in Geo-synchronous Transfer Orbit (GTO). Measuring 17 meters in length and 4 meters in diameter, L110 is an earth storable liquid propellant stage with propellant loading of 110 tonnes. L110 stage uses two high-pressure Vikas engines in a clustered configuration and draws its heritage from the second stage of PSLV and GSLV and strapons of GSLV.

L110 Liquid Engine Static Test failed - ISRO

ISRO HQ Bangalore, March 6: A static ground test of a core stage of a new-generation heavyweight rocket for the future GSLV MK3, planned by the Indian Space Research Organisation, has failed, the space agency announced today.

The liquid-fuelled core stage of the GSLV-Mk3 rocket was to fire for 200 seconds during the ground test at Isro's Liquid Propulsion Systems Centre in Mahendragiri, Tamil Nadu, but was stopped after 150 seconds, Isro sources said.
India's existing Geosynchronous Satellite Launch Vehicle rockets can ferry a 2,000kg- class satellite towards a geostationary orbit 37,000km above Earth. The GSLV-Mk3 is expected to carry a 4,000kg-class satellite towards a geostationary orbit.
The GSLV-Mk3 can also carry a 10,000kg payload into a low-earth orbit — an altitude of about 200km — and is thus viewed as a crucial technology that Isro will need to develop in its bid to launch manned space capsules.
"The ground test on Friday evening was stopped after engineers detected an unanticipated deviation in one of the parameters being observed during the firing," an ISRO official told. While the rocket fires in the static mode, engineers keep track of more than 500 parameters, such as temperatures at various points in the rocket, liquid flow rates and pressure levels, the official said.
The next static ground test will be conducted after analysis of this data. The liquid-fuelled stage has 110 tonnes of propellant and is similar to the liquid stages used in Isro's existing GSLV rockets — only with a greater capacity. In the existing GSLV, it burns for 150 seconds; the GSLV-Mk3 will demand 200 seconds of firing.

The test was aborted after some "minor leakage in the command system", PTI reported, quoting Isro sources. It is a "very minor problem" in which a small leak in the command line was detected by a computer, which automatically stopped the test. "There is absolutely no problem with the engine," a source said. Earlier this year, Isro had successfully conducted ground tests of S200 Solid stages of the rocket.

All the Best ISRO - For the next static test of Liquid 110 and Cryo 25...

India developing winged reusable rocket:


BANGALORE: India is developing a winged reusable rocket and the Indian Space Research Organisation (ISRO) has configured a Technology Demonstrator as a first step towards realising it, the space agency said in a report.

India's space scientists have already configured a winged Reusable Launch Vehicle Technology Demonstrator (RLV-TD). This is a first step towards realising a Two Stage To Orbit (TSTO) fully re-reusable launch vehicle, according to Indian Space Research Organisation (ISRO).

The agency said in its latest annual report that a series of technology demonstration missions have been conceived.

"The RLV-TD will act as a flying test bed to evaluate various technologies like hypersonic flight, autonomous landing, powered cruise flight and hypersonic flight using air breathing propulsion. First in the series of demonstration trials is the hypersonic flight experiment (HEX)," it said.

Meanwhile, for the Chandrayaan-2 mission, expected by 2012-13, ISRO has received 36 Indian payload proposals for orbiter and lander/rover.

The Scientific Advisory Board of Chandrayaan-2, a follow-on mission to Chandrayaan-1, is currently in the process of reviewing the payloads proposed for orbiter.

ISRO sources said the space agency has also received foreign proposals evincing interest to send their instruments for hosting by the Chandrayaan-2 which would be jointly developed with Russia.

It would have an Indian orbiter and mini-rover, and Russian lander and rover.

According to ISRO, the Megha-Tropiques satellite, an Indo-French joint mission for the study of the tropical atmosphere and climate related aspects, is expected to be launched later this year.

It is set to join a string of global spacecraft designated to study climate change.

"Considering the strong global demand for data from Megha-Tropiques, ISRO, CNES (French space agency) and NASA have agreed to integrate this satellite into Global Precipitation Measurement (GPM) constellation of satellites," ISRO said.

"With this, Megha-Tropiques will be one of the eight satellites contributing to the global scientific community to study and understand the dynamics of climate system," it said.

Data from the recently-launched Oceansat-2, which carried an atmospheric sounder 'ROSA' from Italy apart from main payloads - ocean colour monitor and scatterometer -- is highly sought after by international scientific community.

In this respect, a cooperative programme on sharing the data with National Aeronautics and Space Administration and National Oceanic and Atmospheric Administration for their operational research is expected to be signed shortly, it said.
