29. RAMJET
(A GAS TURBINE WITHOUT COMPRESSOR AND TURBINE)
•Most powerful engine and the highest thrust produces than turbojet but it
work most efficiently at speeds around Mach 3.
Optional: Convergent or Con/Di Nozzle

30. SCRAMJET
OPERATES AT MACH 4 AND ABOVE

31. NOTATION
LP = Low Pressure
IP = Intermediate Pressure
HP = High Pressure
1 = Primary Nozzle
2 = Secondary Nozzle
= Low Pressure Shaft
= Intermediate Pressure Shaft
= High Pressure Shaft
