LVM3/GSLV Mark III News, Discussions, Updates and Reports

[karn]

Three cheers to @kurup. He was the first person to post real pictures of our GSLV Mark III.

I think Crysis was first .

@CrYsIs
1.A stark example of how not funding science causes harm .
2.I know but 2025 is still 11 years away there can be a way of increasing its performance by switching around its stages (with existing stages of course ). The more I think about it the more I think that we will see Some modifications like changing out the core solid stage . By the end of it we will probably see a GSLV2XL or something . I am also baffled as to how ISRO never got around to clustering engines if it was so concerned with cost . The GSLV3 is the 1st example of such an effort . Clustering was instrumental in helping the Soviet , China and now spaceX make heavy lift rockets using relatively small engines .
Just look at that.... using 700-800 KN hypergolic engines and clustering together 2 78KN LOX H2 engines China has rockets that meets all her needs .
Guess who else has 800KN hypergolic and 75 KN cryo engines .... Meh never mind Im just disappointed at all the missed opportunities .
I just wish that ISRO had looked into building a core stage with 4 clustered vikas engines at say 1996 .

As i said there was hardly any money for even small tweaking or innovation,the government only sanctioned money for launching once every few years.In those days India's economic situation was very bad and therefore the government was struggling to fund the organization.

You must thank our stars that many of the scientists stayed with ISRO despite the fund crunch,otherwise ISRO would have become another DRDO/HAL.

ISRO should have gone for gas generator cycle cryogenic and semi cryogenic engines right from the beginning,because of it's insistence on staged combustion,we lost over 20 years.Anyways we have now mastered this very complicated staged combustion based engines,So we can literally build anything.Now what ISRO needs to do is to develop the SCE 200 quickly and replace the weak L110 stage of the GSLV MK3 with a clustered SCE 200 which would double the payload capacity to 8 tonnes.

With that kind of capacity GSLV 3 would become a real game changer in international launching market.And now that India is economically doing reasonably well,expect more fundings from the government.

Ok . I guess at this point it is all academic .
An interesting bit of history though . When the french first flew their viking engine (the engine on which the vikas is based) It failed due to combustion instability . So to counter the problem they changed the fuel composition . ISRO on the other hand solved the problem without changing the fuel . ( go ISRO ).
As for the SCE 200 have some pics

Single element thrust chamber and a hot test of a scale down model.
Injector design study .
Dunno how many design teams LPSC has .. Remember the CE 20 has yet to have a ground hot flow test .
Remember the motivation behind the space programme . It was so that India would never be denied space assets . But now the world has changed it is easy for any country or organisation to get something to space because there are so many space orgs that are eager to get business . ISRO should change its stance from self reliance to try and compete internationally . With low cost space travel being offered by more and more entities , ISRO is fast losing its USP.

For engines it ended with Vikas,they might have helped us with electronics and other components.

Launch rehearsal of ISRO's LVM 3 successful

Ahead of the country's maiden experimental launch of latest generation vehicle GSLV Mk III, which would carry out the 'Crew module Atmospheric Re- entry Experiment (CARE) on a suborbital mission on December 18, ISRO successfully carried out a rehearsal on Monday. "The nine hour 30 minutes launch rehearsal of ISRO LVM3 has just been successfully completed," ISRO said in its social networking site. Confirming the success, a senior ISRO official said the countdown for the launch of GSLV Mk III/X CARE Mission (also known as LMV 3) would commence around 8.30 a.m., on December 17 at Sriharikota. Asked about the reason behind the lesser duration of countdown, he said it was a 24-hour countdown before the December 18 launch since the mission would carry only a dummy cryogenic stage. "The countdown would be for around 24 hours and would commence around 8.30 a.m., on December 17. The lift off of the launch has been scheduled at 9 a.m., on December 18," he told PTI. The 630-tonne GSLV-Mk III would carry the 3.65 tonne crew module even as the national space agency is equipping itself for its ambition of sending astronauts into space eventually. However, the Indian government has not approved any human mission to space presently. Realisation of 42.4 metre tall GSLV Mk-III would help ISRO place heavier satellites into orbit. GSLV Mk III is conceived and designed to make ISRO fully self reliant in launching heavier communication satellites of INSAT-4 class, which weigh 4,500 to 5,000 kg. It would also enhance India's capability to be a competitive player in the multi-million dollar commercial launch market.

Awesome .. I was looking all over for the empty weight of the stages.

according to the ISRO official LVM3 mission brochure, the annotation about the second and third Drop Zone should be corrected...

The launch is a success, congratulations to all!
