Any idea about the payload of TSTO ??

10,000 Kg. to LEO targeted - Targeted TSTO Features:

• 10 Ton to LEO and GTO payload capability.
• Vertical take off.
• Semi-cryogenic booster stage with avg. Isp of 330 seconds and cryogenic orbiter stage with avg. Isp of 400 seconds.
• Total lift off weight < 700 tons.
• Winged body booster that will boost the orbiter to Mach 10 at an altitude of 80-100 km then separate and return to launch site and land conventionally on an air-strip.
• Orbiter will deploy the payloads in the intended orbits and then deboost, re-enter and land on airbags or vertically on legs.
• Vehicle structure designed for 100 flights and engines for 50 flights.
• Turn around time should be 30 days.
• Payload fraction = 2%.
• Cost effectiveness < 1000 US $/ kg for LEO payload.

Futuristic Unmanned Space Shuttle Getting Final Touches​

THIRUVANANTHAPURAM: A scaled-down, unmanned version of India’s futuristic space shuttle is getting the final touches at the Vikram Sarabhai Space Centre (VSSC) in Thumba.

With the construction of the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) nearing completion, A S Kiran Kumar, chairman, Indian Space Research Organisation (ISRO), is scheduled to lead a review of the dream project here on Friday.“The ‘space plane’ part of the RLV-TD is almost ready. We are now in the process of affixing special tiles on its outer surface which is needed for withstanding the intense heat during re-entry into the earth’s atmosphere,” SSC director M Chandradathan said.

“The entire construction of the RLV-TD is being handled by VSSC,” he said.

ISRO has tentatively slated the prototype’s test flight from the first launchpad of Sriharikota spaceport for July this year, but the date would be finalised depending on the completion of construction. The proposed RLV is designed in two parts; a manned space plane rigged atop a single stage, booster rocket using solid fuel. The rocket is expendable while the RLV would fly back to earth and land like a normal aeroplane after the mission.

The prototype- ‘the RLV-TD’ weighs just 1.5 tonnes and would fly up to a height of 70 kms.

For the test mission, the unmanned space plane part would glide into the Bay of Bengal a la the recent crew module successfully tested aboard the Geosynchronous Satellite Launch Vehicle Mk-III (GSLV Mk-III) experimental flight last year.India’s answer to the space shuttle, the RLV is one of the big steps forward in ISRO’s launch vehicle programme along with the GSLV Mk-III and the Unified Launch Vehicle project.

ISRO has successfully tested re-entry technology twice- the first time in 2009 with the Space Capsule Recovery Experiment-1 (SRE-1) in January 2007 and the second with the Crew Module Atmospheric Re-entry Experiment (CARE) aboard the GSLV Mk-III in December 2014.

ITS OFFICIAL: RLV-TD TEST LAUNCH IN JULY

The Indian Space Research Organisation (ISRO) is developing a reusable space vehicle and the first scaled-down model of the space shuttle will be test-launched towards the end of July.

"It is going to be an important engineering experiment for the Indian space agency. A small aero plane-shaped vehicle would be launched from Chennai some time during the second half of July," IANS quoted MYS Prasad, director, Satish Dhawan Space Centre (SDSC), as saying.

India launches its rockets from SDSC in Sriharikota, around 80 km from Chennai. The experimental vehicle would weigh around 1.5 tonnes and is only a scaled-down model of the actual vehicle that is expected to carry a satellite.

Officially known as the reusable launch vehicle (RLV-TD), the new vehicle is being developed to reduce the cost of access to space, which could come down to a tenth. At present, the cost of placing 1kg of object in space for Isro is about Rs3 lakh (approximately $5,000), which scientists are hoping to be brought down to about $500 (Rs30,000).

The shuttle that will be driven by a single solid rocket booster with nine tonnes of propellants will initially be used in shuttles for unmanned missions. The spacecraft will be programmed to fly to a height of 70km after which it will descend back to earth and land safely in the Bay of Bengal.

The descent speed would be controlled through the fins on the machine. In order to protect the equipment from friction heat when it comes back, necessary protective tiles have been fixed. About 600 heat-resistant carbon tiles are placed around the nose of the vehicle so that the spacecraft will be able to withstand a temperature of 1,200 degrees Celsius when it re-enters the atmosphere.

After landing, the spacecraft will sink to the bottom of the sea. For now, ISRO has no plans to recover it, apart from seeking the help of Indian Navy or Coast Guard in retrieving the shuttle. ISRO is expected to develop a reentry technology that would help the spacecraft land on a runway like a plane.

Finally!

Actually with respects to the development of the technology itself, the CNSA have demonstrated their capability of building them, namely, with their YF-77, YF-75/D, YF-73, and YF-50T series, the latter being the future engine for the smaller stages of the Long March 5 rocket.

hi @SinoSoldier

You are correct china has definitely demonstrated the capability to design and test 700kN cryogenic engine and 1200kN semi cryogenic engine.For now china seems ahead .But india is also working on a 2000kN semi cryogenic engine that is under advanced stages of development as pointed out by our chairman of ISRO
ISRO's Semi Cryogenic Engine SCE-200 - Indian Space Projects

Here is what chairman said in a speech recently-
First Prototype of ISRO's Semi-Cryogenic Engine To Be Ready By 2016 - AA Me, IN
The specifications of our semi cryogenic engine surpasses that of china's but then again chinese engine has passed all the flight certifications and would be launched next year,indian engine on the other hand will be test fired for the first time on a rig next year- actual flight might take at least 3 years!
Unfortunately india doesnt have an equivalent of china's YF-100(a cryo engine with 600-700kN thrust).India's 600kN cryogenic engine is still on drawing boards and would not be ready for test atleast for next 5-8 years! India's most powerful cryogenic engine can do only 200kN
Finally here is how our GSLV MK-3 will look like with SCE-200

ULV

Was there a launch in march, as the thread title states?

Postponed to December I think..

 

[cirr]

Postponed to December I think..

December which year？

 

[gslv mk3]

December which year？

This year...we don't have several launch pads-the reason for delay.

2015... Good

 

[sathya]

December which year？

There Is no hurry as far as RLV is considered..

GSLV is..

--------------------
I hope we get a new launch pad in Southern Tamil Nadu , closer to equator , lesser the fuel required.

I personally think this project will be de-prioritized and a 'heavy' SSO class rocket will be focused on. Winged return vechicles are still a bit of a white elephant. Just my 2 cents. I mean the Shuttle cost one billion USD per launch. The commercials are still very weird around this.

@amardeep mishra @Kinetic @gslv mk3

What is actual plan and target of ISRO in the broader term.
I mean India going for semicryogenic engine, scamjet, Hypersonci reusable entry vehichle, Plan to send manned mission in space what is the real agenda.

1) Is it to take the share in the future space tourism.
2) Space exploration to benifit the whole world.
3) Race with the China as the matter of pride and prestige
4) Helium, the future fuel, as all fossil fuel would be spend till the end of the century.
5) Profits in space, satellites, spacelab transportion.
6) Gain Knowledge at its own expense.

December which year？

There is a website in China tracking Indian's space programs. Some of them have been overdue for more than 10 years.
