Yeah.... I could imagine it to be a SCRAMJET engine (why settle for RAMJET) underneath the missile. Only problem is its shape and position in the missile. We could see the rear fins of the missile just after the portion. Now as far as my knowledge goes, even our SFDR is a RAMROCKET short of arrangement rather then what ISRO tested.Yes , just for the sake of curiosity , after the yellow stand , it seems to have a additional section below .
Well it might be optical illusion also.
Anyways it could have been the DSCM ( Dual Speed Cruise Missile ) with a turbofan as main stage and a ramjet engine as second stage.
Sir please try to imagine things sometimes :biggrin2:
But yeah, imagination could run wild. :biggrin2:
