Question

Rockets Can Move In Air Free Space, But Jet Planes Cannot. Why?

Answer 1

A rocket is a projectile that uses a rocket engine to provide propulsion to spacecraft, aeroplanes, and other vehicles. Rocket exhaust is completely made up of fuel carried by the rocket. Rocket engines work on the principle of action and reaction, propelling rockets ahead by ejecting their exhaust in the opposite direction at a fast rate, and therefore can operate in the vacuum of space.

Complete step by step solution:
A jet plane is a plane that is powered by jet engines. Jet engines attain optimum efficiency at speeds close to or even well over the speed of sound, whereas propeller-powered aircraft engines reach maximum efficiency at considerably lower speeds and altitudes.
The concept behind jet engines and rockets is the same. The concept is straightforward. Both combine air and fuel to spark combustion, which pushes against every side of the engine except the exhaust in the back, which can't be pushed against because it's a hole. A rocket is a spaceship, missile, aeroplane, or other vehicle that uses a rocket engine to generate thrust. The fuel transported within the rocket before usage is used fully to create the engine exhaust. A rocket is self-sufficient since it contains both the oxygen and the fuel required to burn the fuel. As a result, a rocket can go across space without needing to breathe.
Jets, on the other hand, have just fuel. To burn the fuel, it requires oxygen from the environment. One aperture serves as an intake nozzle, while the other serves as an exhaust nozzle in jet engines. As a result, a jet plane cannot fly in a vacuum.

Note:
The principle of jet propulsion is used in rocket engines. There are many distinct types of rocket engines that power rockets; a complete list may be found in the main page, Rocket engine. The majority of today's rockets are chemically driven (mostly internal combustion engines, although some use a decomposing monopropellant) and generate a hot exhaust gas. Gas propellants, solid propellants, liquid propellants, or a hybrid combination of solid and liquid propellants can all be used in a rocket engine.
