Test: Jet & Rocket Propulsion System - 1 - Question 3

Ram compression manifests in

Test: Jet & Rocket Propulsion System - 1 - Question 4

The compressor does not form a part of

Detailed Solution for Test: Jet & Rocket Propulsion System - 1 - Question 4

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.
