First Look: India's Heaviest Launch Vehicle GSLV Mk.III with Unmanned Crew Module Onboard Rolled Out

[Guynextdoor2]

Oh of course, for the mighty Guynextdoor can build cyrogenics and semi-cyrogenics all at the same time within ISRO's budget and infrastructure while blasting all earlier records of development time for cyros ( most over 10 years) at that.

Btw Your sentence should have read 'cyros only after semi-cyros'.

Guynextdoor definitely can.

 

[vsdave2302]

What is the point of adding another 2 SRBs ?

To provide additional boost in boost (First) Stage.

 

[SOHEIL]

To provide additional boost in boost (First) Stage.

What about the total impulse !?

Update from SDSC, Stiharikota -

The 9 hr 30 minutes launch rehearsal of LVM-3 Experimental sub-orbital flight has just been successfully completed. All the data would be checked for one last time in the Mission Readiness Review planned on Dec 16. Launch, as we said, is planned on December 18.

ISRO's LVM 3 X flight is planned on December 18, 2014.

Experimental flight of LVM-3 will carry active Solid boosters (S200s), Liquid core stage (L110) and a passive Cryogenic stage (C25).

The primary objective of this experimental flight is to validate the complex atmospheric ascent regime of this all new launcher, especially the aerodynamic and control features that cannot be conclusively tested on ground.

In this sub-orbital flight, the launcher would climb to an altitude of about 125 km. Taking advantage of this opportunity, a CARE (Crew-module Atmospheric Re-entry Experiment) Module is planned to be injected at this altitude. This module has been realized to validate a number of technologies developed under ISRO’s “Critical Technologies for Human Spaceflight Programme”. This Module is planned to be recovered from the Bay of Bengal after the splash down.

ISRO's most powerful launcher ever, GSLV Mk-III rolls out from the Vehicle Assembly Building to the launch pad for its Experimental Flight slated later in this month.

No idea buddy ...... but they keep track of Indian missile and rocket tests .

and decided to get cyrogenic via ToT

Hi,
I was casually going through the thread and then came across this,i would like to add that,we never really got full TOT from russians regarding the cryo engine. The supply of tech ran dry far earlier in the development stage than we might think.
Besides unknown to many members ,india started working on cryogenic engines way back in mid 80s,that engine though was based on gas generator cycle producing 120kN of thrust or the long forgotten CE-12!- an entirely indian development effort! things were progressing rather slowly and ISRO was facing critical challenges/hurdles in the design and it was that time ,ISRO got russian cryo engine(the initial contract envisized 2 cryo engines and full TOT),which although had a little lesser thrust than the engine we were already working on,but was based on a radically new cycle "staged combustion cycle"(a cycle that had instability issues and the engine itself wasnt fully ready when it was handed over to india).However staged combustion cycle offers higher thrust at the same mass flow rate and hence a better mass fraction of the rocket. indian CE-7.5 although loosely based on russian cycle, incorporates a great deal of changes as compared to the russian base cryo engine
The bigger CE-20 that will be used in all GSLV MK-3 upper stage, is based on a gas generator cycle producing a max of 220kN of thrust.More powerful cryo engines like the one capable of delivering 600kN of thrust are still on drawing board

 

[Ammyy]

There is a reason why ISRO is calling it LVM III and not GSLV MKIII .

Since the vehicle lacks active Cryogenic engine ...it is suborbital test ...it will not reach Geo Synchronous orbit ...so it is being called LVM III.

What is meaning of LVM

 

[kurup]

What is meaning of LVM

LVM 3 = Launch Vehicle Mark 3 .

I am aware of all that. Never mind.
Do share some insider info about the 600Kn cyro Is it for the ULV? And some info on ULV would be nice too
