If you are operating at 1000 knots and altitudes of 60,000 feet, what type of propulsion system should you use?​

Solutions

Expert Solution

If we are operating at 1000 knots (1852 kmph) and 60,000 feet (18.288 km), the propulsion system that must be used is jet propulsion.

An aircraft or rocket is propelled forward by a jet of hot exhaust gases. These gases are produced when air is forced into the jet engine by heavy compression (centrifugal, axial or ram compression) and is heated in the engine and is expanded through a nozzle.

Rocket propulsion is a category of jet propulsion which offers a very high thrust force for lighter crafts and can practically reach any height, even space. The major drawback for rocket propulsion is its fuel inefficiency and the need to carry both the oxidant and the propellant.
