Re: Indian Missiles News and Discussions - May 2017

PTAE-7 engine was made with re-use in mind in fact it has been tested for splash down in sea , recovery and then re-use so from material pov it was not conceived for one time use per se , all in all there is room to make it cheaper but that is probably not a priority item.

Brahmos is ram jet powered it requires the missile to be accelerated above Mach 1 before the main motor kicks in ; so when you employ a VLS you have to get the missile air-frame aligned correctly prior to main SRB kicking so that you get to ram jet phase in most efficient manner.

Indranil on 'project stalling point' if this flight was indeed powered by the PTAE-7 then why were we even using Saturn engine all this long ? We could have finalized upon this from very beginning until the MANIK came online.

PTAE-7 is iffy imo as it has a very high SFC (1.15 kg./kg.f/hr) as against about <0.7 kg/(kgf∙h) for NPO-Saturn's 36MT so despite thrust figures being close range and loiter time will be have to be compromised ; not that we should let the perfect come in the way of good but then if PTAE-7 indeed wor...
