How to make a liquid propellant rocket engine.If your answer helps me I'll mark you as brainlist for sure
Answers
Answer:
A liquid-propellant rocket or liquid rocket utilizes a rocket engine that uses liquid propellants. Liquids are desirable because they have a reasonably high density and high specific impulse (Isp). This allows the volume of the propellant tanks to be relatively low. It is also possible to use lightweight centrifugal turbopumps to pump the rocket propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks that do not need to resist the high pressures needed to store significant amounts of gases, resulting in a low mass ratio for the rocket.You can easily make homemade rocket fuel using potassium nitrate, sugar, and water alone. Just let the sugar cook down a little more to ensure that it's melted enough to make it manageable.
