QUESTION: 1

Solution:
QUESTION: 2

Solution:
QUESTION: 3

### The thrust augmentation of turbojet engine can be effected by the following methods except

Solution:
QUESTION: 4

The surrounding air is not used as oxidiser in

Solution:

One major difference between the rocket engine power plant and other jet propulsion systems is that the rocket carries its entire propellant (oxidiser and fuel) with it. Other jet propulsion systems depend upon atmospheric air.

Solution:
QUESTION: 10

Thrust in a rocket depends on

Solution:

Thrust is given by

where,
m = Propellant flow rate
Cj = Exhaust velocity
Pn = Nozzle exhaust static pressure
Pa - Atmospheric pressure
Ae = Nozzle exhaust area
