What will be the Payload of GSLV MK III to LEO?

[IND151]

The GSLV-III or Geosynchronous Satellite Launch Vehicle Mark III , is a launch vehicle currently under development by the Indian Space Research Organization. GSLV Mk III is conceived and designed to make ISRO fully self reliant in launching heavier communication satellites of INSAT-4 class, which weigh 4500 to 5000 kg. It would also enhance the capability of the country to be a competitive player in the multimillion dollar commercial launch market. The vehicle envisages multi-mission launch capability for GTO, LEO, Polar and intermediate circular orbits.
GSLV-Mk III is designed to be a three stage vehicle, with 42.4 m tall with a lift off weight of 630 tonnes. First stage comprises two identical S200 Large Solid Booster (LSB) with 200 tonne solid propellant, that are strapped on to the second stage, the L110 re-startable liquid stage. The third stage is the C25 LOX/LH2 cryo stage. The large payload fairing measures 5 m in diameter and can accommodate a payload volume of 100 cu m. Realisation of GSLV Mk-III will help ISRO to put heavier satellites into orbit.





Typical Parameters of GSLV Mark III
Lift-off weight 630 Tonne
Pay Load 4 Tonne in to Geosynchronous Transfer Orbit (GTO)
Height 42.4 metre








Question > what will be the payload of MK III to LEO and if it is 10 tons like some articles suggest, will it be with 4 boosters?

kindly discuss the topic and don't post OTPs

For Mk3 Its 10 tonnes for LEO n 4-5 tonnes for GTO.

The GSLV mk2 has a capacity of 5 tonnes LEO n 2-2.5 tonnes GTO.

Hope that would help...

Its hard to guess the payload size just by the weight of the rocket..One major factor is the efficiency of Rocket motor depending on type of fuel and motor design.
Russian RD-180 still beats any modern western rocket motor despite being 1960s tech,so it really depends what fuel the rocket is using and how good is the motor design.
The wiki article about GSLV MK III says that the rocket will use an Indian Built CE-20 Cryogenic engine,and normally rocket design does allow variable number of boosters to be strapped on,so like you say there may be more than 2 boosters on GSLV for higher payloads.
You will be better off comparing it to Ariane-5 rocket for comparison of rocket size and payloads.

Here you can see the effect of engine efficiency...Ruskies win

Atlas-5 with Russian RD-180
Mass 334,500 kg
Payload to LEO 9,370–29,400 kg

Ariane-5 with European Vulcan-2

Mass 777,000
Payload to LEO G: 16,000 kg
ES: 21,000 kg

There is no official confirmation for 10 ton payload(i.e ISRO site)

 

[Safriz]

Just a thought...
Wasn't it easier and perhaps cost effective to buy a Russian RD-180 or 170 and use it for Indian rockets than developing their own?

Well, ESA could have bought engines from NASA, but they didn't. So the cost factor does not come with national pride. But just try it according to your pocket capacity. It gives immense pleasure when it is successful. If it is a failure then make a sombre face and try to do it better. Pakistan should also try this, may be in a small scale and feel the joy.

The Indian Space Research Organisation will develop a new GSLV Mark III, its heaviest, tallest and most powerful rocket. The 42.4-metre-tall rocket will have a lift-off weight of 630 tonnes and can put a four-tonne satellite into the geo-synchronous transfer orbit (GTO) or a 10-tonne satellite into a low-earth orbit. In comparison, the GSLV flight of May 8, belonging to the first generation of GSLVs, put a 1.8-tonne satellite in the GTO. The GSLV Mark II can put 2.2- to 2.4-tonne satellites into the GTO.
GSLV Mark III is not derived from the Polar Satellite Launch Vehicle (PSLV) or the presented GSLV. Although it is called Mark III, it is a totally new vehicle. Its upper stage will be powered by a cryogenic engine developed at the Liquid Propulsion Systems Centre (LPSC) at Mahendragiri in Tamil Nadu and codenamed C-25. It will have 25 tonnes of propellants - liquid hydrogen and liquid oxygen - which will develop a thrust of 20 tonnes.
Besides the cryogenic stage, GSLV Mark III has a core stage of two engines powered by 110 tonnes of liquid propellants and two huge strap-on motors strung around the core.
Each strap-on motor of the Mark III will be 3.4 metres in diameter and they will be 25 metres tall. The challenge here is that India will develop a huge booster with 200 tonnes of solid propellants, and a cryogenic stage with 25 tonnes of propellants.
The development work on Mark III began in October 2002. New facilities will be established at Sriharikota and Mahendragiri to develop the solid boosters, the core liquid stage and the cryogenic stage. A massive plant will come up at Sriharikota to produce solid propellants for Mark III. This will be in addition to the existing Solid Propellant Booster Plant (SPROB) facility at SHAR, one of the biggest plants of its kind in the world. The private and public sector industries taking part in the project too have to augment their facilities for the realisation of Mark III hardware.

Its not completely indigenous. Ukrainian technology is being used.
