QUESTION: 1

Solution:
QUESTION: 2

Solution:
QUESTION: 3

Ram compression manifests in

Solution:
QUESTION: 4

The compressor does not form a part of

Solution:

A deceleration of the air from Mach number 3 at diffuser inlet to Mach 0.3 in combusion chamber causes the pressure ratio to rise to more than 30. Due to shock and other fosses inevitable at such velocities., all of the pressure rise is not available at the required combustion pressure. This principle of ram pressure rise is used in the ramjet engines. Thus compressor does not form a part of ramjet.

QUESTION: 5

Compared to turbojet, a turbo prop has an additional feature in having

Solution:

Components of turbo prop engine:
Propeller, Reduction gear, Diffuser, Compressor, Combustion chamber, Turbine, Nozzle Component of turbojet engine:
Diffuser, Compressor, Combustion chamber, Turbine, Nozzle.

QUESTION: 6

Solution:
QUESTION: 7

Which of the following propulsion units has reduction gear as one of its essential component?

Solution:

Reduction gear is placed between turbine shaft and propeller to enable the propeller to operate efficiency.
