Re: Kaveri & aero-engine discussion

DMRL seems to have built a new batch of HPT SCB blades and vanes for the new cores. They are calling for manufacturing of a new transit case.

Re: Indian Space Programme Discussion - Sept 2016

Stage thust of solid stage tapers rapidly after 130 sec, but still needs to drop significantly so that comparatively lesser thrust / impulse of retro rocket become useful (in addition to Aero load) . Haridasji, I am aware of the thrust tail out on solid rockets. However, on GSLV Mk3, they cannot wa...

Correct. So the Astra SAM conversion is perfectly sensible. If QR SAM didn't exist I would say so but existence of later with some of same components and similar range makes such a SAM redundant. Also, QRSAM has been designed ground up as a SAM. For example, the sizing and propellant of the booster...

Re: Indian Space Programme Discussion - Sept 2016

It can be a reason. But ISRO takes care of this for S200 in a different way. The joint in the front is pyro separated moments before the joint at the back. This makes the residual energy of the spent stages take them away from the rest of the vehicle.
