Wont there be video tracking the decent from surface ships .. is that possible ??

Not likely because, I believe, the safety zone is a no-go area for ships and aircraft. So the descent might have happened far from any visually tractable area. The recovery vessels must have been stationed outside the zone.

I just wanted to know whether this test was done without cryogenic engine ????

Yup, no cryo, there was just a dummy in place to simulate the weight.

 

[Compersion]

there was mention of a video of "separation of the stages" by one the scientist in the video after the launch was successful and they were giving speeches where he said it would be good if the video was shown. does that mean there was on-board camera - it was caught on video by the ground ...

***** Added later:


At 52:19 - where he talks about separation ...

As far as i know There is no missile that is based on cryogenic Engine... its always been used for space programs and there is lot of Unknowns on that episode .. hope the truth comes out

Just because there are no missiles based on cryogenic engine doesn't mean that one cannot build a missile with cryogenic engine.

Cryogenic engine is basically an upper stage engine with high specific impulse which perfect for a long range missile but the main draw back is that it cannot be stored like solid rockets and therefore is not used in missiles.But if it falls into the hands of rouge nations like North Korea, then there is a real danger.

I feel that your on the right track there - the cryogenic is a powerful engine nad with a little ingenuity
can be modified to power missiles to icbm status and that was one main reason it was and still is denied
to India ..............as we didnt sign those discriminatory MTCR and NPT's etc etc

so now when we are close to developing it on our own, dont be surprised, they'll suddenly offer it to us and
ask us to sign this that and the other ........ hah ! :clap:.

The non storablility is what makes it a non missile tech.. what use if for a missile when you can find out if your going to launch in sometime and then the reliability in war like conditions.. thats the reason why its never been used . its complex and not enough returns

Surely using a cryo engine does not make a good missile but you can still use it for missile purpose especially if you are a rouge desperate country like North Korea.

Some good news :
Godrej Aerospace to make semi-cryogenic engines | Business Line

The SME project was approved by the Government of India in January 2009 at a sanctioned cost of ₹1,798 crore. Department of Space's Outcome Budget for 2014-15 says that the project is "in the initial stages".

It expects the engine to be fully developed "after six years".

Till the end of March 2013, ISRO had spent ₹155 crore on the project. Godrej will make six engines for ISRO. Vaidya said the company had begun work on three.

It is as much as we can hope .. The gap between GSLV1 ---GSLV 2 9 years GSLV2 - GSLV 3 --- 8 years (tentatively) GSLV 3 --ULV(6-7) years .. A good development pace ..Especially now that the project is fully funded .

That made me angry....this thing should have been started even before the cryogenic project.

Because of this late start we are forced to use the outdated UH25/N2O4 engines.Anyways hope they achieve this target at the earliest.

Like i said before ----- please, please swallow pride and for the sake of the nation,
hand drdo, hal , kaveri development over to these men and women

The sooner we realise and act on that, the better for the nation..

At the very least, form a national committee to oversee and comment
on the development of each and every project which has defence and strategic
implications and as a MUST, include top level staff
from ISRO to be part of the committee .

Secondly publish in the form of a grid chart, the progress of each project, the amount of
(taxpayers) money spent since inception, the time taken so far and the stage reached
It will act as an annual report card which should be published for the nation to see.

The report card will omit and sensitive disclosures and top secret projects will not
be mentioned .
Indian people can then give their views and we can have televised debates about the success
and the failures and those in the the grey-area .

Projects which are repeat failures can be questioned with managers motivated or substituted.
Projects which show good success can have their managers rewarded and given greater and
higher responsibilities.

Before long a pyramid structure of human resources in technology management will emerge
That is the reality of the situation and we being a huge nation should have hundreds of thousands
at the top of the pyramid .
If we reward those, they wont migrate out and help other nations
at our expense ( as is happening now ) and our projects will forge ahead
perhaps as good or even better than our neighbour.

Ha Ha Ha .....

It seems you wish to be banned or humiliated in this heavily influenced DRDO forum ....

 

[CrYsIs]

We still have a long way to go.........

@Ray @LETHALFORCE @Kunal @pmaitra
1) i asked for a national apex committee with representation from all concerned
to oversee the progress of all projects of defence or national strategic interest .
and to ensure that ISRO top management were included in that committee

2) I asked for a national report card on all projects - to be made public
Even without such a report card the media is calling into serious question the progress of
important and super-expensive projects . This was published just yesterday :-
32 years on, IAF to get Tejas fighters in March - The Times of India
Commenting on the article, I dare say the tone was not sarcastic or unfair in any way but rather it was
pro-national and sincerely asking why after 32 years of development , there still remain serious
fundamental flaws in the product which in a sense rending the project still incomplete after 32 years.

In a previous article in Indian media they pointed out that the ejection system
would have the pilots feet seriously injured by being caught in the cockpit top - serious and
fundamental gaping flaws and NOT a completed project.

So all i am asking for is that the same introspection be applied to ALL projects and done in a more
systematic and orderly manner

3) Now who would object to that ?
only those with something to hide
only those who are non-productive and have special pockets -

are they on this forum ? do you seem to know ? - so tell us who they are ?

4) Bro, there is a jokes section on this forum - it's somewhere else - not this thread. please

 

[pmaitra]

ISRO is a dedicated space organization.

DRDO is an umbrella organization with lots of labs, some doing very well, some not so well.

We can discuss DRDO in the appropriate thread.

In this thread, I would welcome information on the under-development cryogenic engine for GSLV Mark III.

 

[LalTopi]

We still have a long way to go.........

They seem to have the labels the wrong way round. If GSLV III can lift 10 tonnes to GTO, then I would be a very happy man.

Anyway, the main goal should be for India to be self sufficient in launching satellites and not worry about who can lift the most! or who can send humans to the moon. The moon is not in any hurry - it hasn't seen humans since 1972 and not complained once.

Yup, no cryo, there was just a dummy in place to simulate the weight.

so what is difference between mark3 and old gsv ??????

we have only once tested cryo engine ISRO must test with others to know sure that indigenous cryo engine is reliable horse

Saaar, this is actually a new launcher, uses the 2 s-200 boosters , the core stage L110 - 2 vikas engines, and the third and final stage, c-25, that uses the c-20 engine. The engine for this is not ready yet, it will be within 2 years. The launcher is actually different to GSLV, the older GSLV used other engines like the c-7.5.
Check out the differences here:
GSLV - ISRO
LVM3 - ISRO

I guess they want to change the name of the launcher to LVM-3, to differentiate them and also to break away from the GSLV name
