ISRO releases Footage of GSLV D6 on-board cam !

[Tech Support]

For the first time, ISRO has released a video showing footage from an on-board camera! the video is from the GSLV D6 launch on Aug 27, this launch was important because it was using an indian Cryogenic upper stage engine ( rather than the usual Russian ) the Payload was a new GSAT.

the vid shows the separation of the first stage along with the strap-on boosters, and the ignition of the Cryogenic upper stage.

Nice. Other space agencies should take notes "How to make impressive clips for the public"

the first part of the video is the separation of the second stage from the first - the second stage still use UDMH + N2O4. then, given that we don't see the interstage falling off in the second part of the video, i think it's effectively the separation of the second stage from the third stage

the indian GSLV rockets first stages have always been a bit out of the norm design wise

For the MkI & MkII (the one on the video) they use a SRB core stage, flanked by 4 liquid boosters - However, the SRB has a shorter burn time than the 4 liquid boosters, so it stays with the whole stack until stage separation

For their upcoming MKIII, they use two SRBs flanking a liquid core stage with two vikas engines - except the core stage is only air started once the SRBs thrust starts dropping at the end of their burn time - the SRB continue with the ignited core stage till they flame out then separate from the core stage.
