List of top Aerospace Engineering Questions on Rocket Propulsion asked in TS PGECET

A vertical rocket has mass \(10,000\ \text{kg}\), thrust \(150,000\ \text{N}\) and drag \(20,000\ \text{N}\). The instantaneous acceleration (in \(\text{m/s}^2\)) is

Which of the following increases the thrust of a rocket engine?

Drag loss in a rocket flight is

A rocket stage that ignites after the previous stage is jettisoned is called

Gravity loss during rocket flight occurs because

A rocket produces maximum thrust in vacuum because

In a solid propellant rocket, the thrust level is primarily controlled by

One major advantage of liquid propellant rockets over solid propellant rockets is

For maximum thrust in a rocket nozzle, the exit pressure should be

Liquid chemical rockets are often classified by the type of propellants used. Which of the following is correct?

In multi-stage rockets, the stage mass fraction is defined as

Specific impulse of a rocket engine is defined as

During a rocket launch from Sea Level to Space, a fixed-geometry nozzle that is over-expanded at the launch pad will eventually become
