Which of the following thrust modulation techniques uses a normal shock to reduce total thrust?

Which of the following thrust modulation techniques uses a normal shock to reduce total thrust? Correct Answer Shock Thrust Modulation

Shock Thrust Modulation (STM) involves an axisymmetric injection of secondary flow into the diverging section of the supersonic nozzle and the creation of a normal shock by the interaction of oblique shocks. Across a normal shock, a supersonic flow becomes subsonic, thereby reducing exhaust velocity and total thrust. Fluidic Thrust Modulation is divided into STM and TSTM.

Statement (I) : When a bluff body moves at supersonic speed in still air, an attached shock wave is produced at its nose causing the flow to be subsonic behind the shock plane. Statement (II) : A normal shock always transforms supersonic flow into subsonic flow causing increase in pressure, temperature and entropy.
Specifying the temperature ratio across the normal shock wave will yield which of the following across the normal shock wave?
Total pressure loss in a normal shock diffuser is less than the oblique shock diffuser.
