Operating Envelope of Flight Vehicles & Engine Operating Limits
Operating Envelope: Flight Vehicles: Each engine type will operate only within a certain range of altitudes and Mach numbers (velocities). Similar limitations in velocity and altitude exist for airframes. It is necessary, therefore, to match airframe and propulsion system capabilities. Figure...

Introduction & Classification of Propulsion Systems
Propulsion: Propulsion is the act to drive a propulsive vehicle forward by producing thrust in flight. Thrust force is developed based on the Newton’s laws of motion. Propulsive System: It is a machine (engine) that produces thrust to push an...

How the rocket engine works…?
Rocket engine A rocket engine is a type of jet engine that uses only stored rocket propellant mass for forming its high-speed propulsive jet. Rocket engines are reaction engines, obtaining thrust in accordance with Newton’s third law. It is a...
