how gasolene rocket engine works?

Answer 1

Rockets do not run on gasoline.

Some do use a kerosene derivative as a fuel, however, the most common liquid rocket fuel is a Liquid Hydrogen/Liquid Oxygen mixture.

Some other common liquid rocket fuel/oxidizer mixtures:

RP-1/LOX
kerosene/LOX
N2O4/Hydrazine
N2O4/MMH
N2O4/UDMH
LOX/Hydrazine

All rockets (chemical) require a fuel and an oxidizer.. liquid rockets have seperate tanks for each liquid component... Solid rockets have both the fuel and oxidizer mixed together in a solid state.

The reason that they must carry an oxidizer is because oxygen is a must for combustion to happen. An airplane or car uses the oxygen in the atmosphere being pushed into their engines to work. A rocket, once in space, will not have air to use (no oxygen in space) so it must carry its own oxygen with it.

Some systems use hypergolic fuels, which mean that they ignite upon contact with eachother...

To answer you question about how they work:

A liquid rocket is relatively simple, unless I get into the thermo and fluid dynamics, turbomachinery, and all that stuff... but in essence a liquid rocket has a fuel and oxidizer tank. The two are pumped into the ignition chamber (much the same as fuel injection works on a car), then are ignited by a spark. The mixture releases enormous amounts of energy once ignited, and then the whole mass of combusted gases are ejected through the nozzle (a nozzle essentially convert the potential energy in the combustible gases into kinetic energy; the faster the gases move the more thrust you get from the engine)... all that mass thrown out the back of the rocket pushes the rocket forward.

Answer 2

The only gasoline rockets I know of were built by Robert Goddard before the Gov't got involved in it. But it worked just like any other liquid fuel. Pressurize, vaporize, and stand off while it starts to oxidize!

Answer 3

There is no gasoline rockets i know off. The closest that was used is the Saturn 5 stage 1 and 2 used kerosene as fuel. They carried liquid oxygen and burn the kerosene mixed with oxygen

Answer 4

it works as the same way like the octane rockets
burning of fuel in rocket results in hot gases which shoot out backwards. the reaction of hot gases thrown backwards from the rocket provides the forward thrust......

Answer 5

Great!
Action = reaction
The hot gasses go out at the 'left' side' . They carry impulse with them. The rocket moves to the 'right' side. It has an equal amount of impulse to it move-side.

Answer 6

you will could desire to build a working style to coach it (which you should to comb up on your spelling earlier you deliver NASA any form of letter approximately it). and you will could desire to mathematically clarify the thank you to "bend and enhance area". and maybe clarify how the south magnetic pole is "larger" than the north magnetic pole (no longer the case in any magnetic field basic). they're going to possibly could desire to renowned that.
