This liquid is usually oil based because:
Non compressible
Self lubricating

Abstract
ROCKET PLANE
What does it feel like to fulfill a dream?
How will you describe what the Earth looks like from space and looking out to see the stars and the Moon in a black sky in the middle of the day? Will it feel somehow more magical, yet more fragile? Will the world around you look the same?
You ve waited your whole life for this flight, and now the time has come to take the ride of a lifetime. Your day begins with a special breakfast and a brief photo shoot. Then you board this space plane as its called ....etc

CHEMICAL ROCKET ENGINES
1. INTRODUCTION
Chemical rocket engines, like those on the space shuttle, work by burning two gases to create heat, which causes the gases to expand and exit the engine through a nozzle. In so doing they create the thrust that lifts the shuttle into orbit. Smaller chemical engines are used to change orbits or to keep satellites in a particular orbit. For getting to very distant parts of the solar system chemical engines have the drawback in that it takes an enormous amount of fuel to deliver the p ....etc

Rocket engines
Rocket Engines are reaction engines and obtain thrust in accordance with Newton's third law. A rocket engine is a jet engine that uses only propellant mass for forming its high speed propulsive jet. Most of them are internal combustion engines.

Principle of operation
Rocket engines produce thrust by the expulsion of a high-speed fluid exhaust which is a gas most of the times, created by high pressure (10-200 bar) combustion of solid or liquid propellants, consisting of fuel and oxidiser components in the comb ....etc

A water rocket is a type of model rocket using water as its reaction mass , The water is forced out by a pressurized gas, typically compressed air. Water rocket engines are most commonly used to drive model rockets, but have also been used in model boats, cars, and rocket-assisted glide,The term aquajet has been used in parts of Europe in place of the more common water rocket
