ISRO to mate cryogenic engine with its rocket Friday

[Yogi]

This is a second stage engine?
First stage in PSLV and GSLV is solid fuel?

No this is 3rd stage engine, Second stage is powered by Vikas engine n only first stage is powered by Soild fuel similar to PSLV.

PS: this GSLV Mk2 cofig.

6th August looks like it's going to be the third 4th of July this year. Let's see if it's more spectacular than the Proton-M mission carrying the GLONASS satellites.

GSLV Mk-1 and GSLV Mk-2 are similar, except that in Mk-2 the Cryogenic upper stage is indigenous, instead of Russian

Yup you should sit and see while we launch rockets.

Jealous? Don't worry we'll launch your satellites at affordable prices!

They don't have a satellite to launch, and no price is affordable
for their weak economy.

These are the satellites built by Pakistan

Badr-1

Badr-2

Our university students build better satellites.

Pakistan's scientists must use the satellites developed by Indian students as a
benchmark to develop their own. Or maybe they should come to India for a few training
sessions about how to design and build advanced satellites.

I have to admire ISRO for being stuck in the 70s.
This design is similar to 60s-70s Ariane-1 rocket...Back then they had 4 stages of all types...Solid then hydrazine then cryogenic and back to solid..
But the more moving parts,more chances of failure...
No wonder Ariane reduced their number of stages.
So many stages are needed when none of the engines are powerful enogh..because rocket has to keep shedding weight to help the engines moving..
More seperations are needed...more ignitions required...if any seperation or engine ignition fails....the mission goes kaput...
They should have tried to make powerful engines than so many little insufficient and tricky engines?.

@Dreamreaper Are you making fun of ISRO or ?

 

[shuntmaster]

@Dreamreaper your services are very much required at SUPARCO..

Well you cant deny anything india makes is unnecessarily complicated when simpler designs are available..

haha completely destroyed them

How many stages and engines do the latest Chinese rockets have?

What you consider "simpler" is actually more costly and more painstaking to develop.

You don't get to higher levels of tech without neatly sealing off the lower levels, otherwise you
are bound to fail more often.

How different is it from Delta II?
