How do I build a Spaceship Engine?

Question

Just wondering. Must go at least 25,000 mph to escape the earths gravity. I am posting this again because I did not get enough answers last time.

Answer 1

create a parallel universe in which you've already built your spaceship engine.

that should do the trick

Answer 2

Buy the blueprints off NASA.com

Answer 3

I don't know the specifics. But I DO know your gonna need alot of duct tape.

Answer 4

why dont you just go to a school on how to build one instead of asking average joes about it.

Answer 5

B. gave you the right answer. very carefully

te first propellant used was alcohol and oxigen, in the V2

then they reused the oldest propellant, (potasium perchlorate) in the way of amonium perchlorate, much lighter

adding iron oxide and some other stuff

LOX+LH2 is also a  possibility

hidracine is not at your reach

any way, all rockets are controlled bombs. just remember how many failures they had in the space history

to make it safe, it takes a lot of $$$

Answer 6

Buy One

Answer 7

Crazy glue, tinfoil and other random household items.

Answer 8

If you have to ask in this way, you probably lack the know-how in metallurgy, systems, combustion and control engineering required, so any information would be lost on you.

Are you familiar with the concept of specific impulse? Of fuel mass fraction? Of convergent-divergent nozzle, and how they need to be adapted to the external pressure (i.e. a nozzle meant to operate in the lower atmosphere will not be efficient at higher altitude and in vacuum, and vice versa)?

Still want to do it? Okay. Here is how. First, get yourself a $2 billion budget, and hire a team of 500 aerospace engineers of various specializations, 1500 technicians and skilled machinists; you will probably also need 500 support staff as well (payrol, office maintenance, secretarial, etc.) You will also need to procure lots of exotic alloys, metal forming tools and machines, and secure supply of rocket fuel (liquid oxygen and hydrogen usually) for the qualification and development firing tests.

Go get this, and ask again. I will give you the next step after you got all that.

Answer 9

Our spaceships today are still primitive.

Someday we will find better ways to travel around space, like creating artificial wormholes so the ships jump from our atmosphere into the space directly.

Answer 10

Very carefully!

Answer 11

Send an email to Zephrem Cochran. Father of Warp Drive.

Answer 12

Use much of Hydrogen fuel! If wanna conserve nature and money, then I'd advice to use Methane as a fuel.

Answer 13

Ask NASA. I doubt they'll tell you, but it's worth a try.

Answer 14

You'll need:

A plunger

Peanut butter

A bucket

A clock

100, 000 dollars

Some old 50's records

and a car

There you go

Answer 15

Well, you can rule out pulse jets or any other type of engine that will need air. You'll need a good rocket engine. A rocket is really very simple, but you have to understand a lot of complicated things to get it to work.

_____

Things to consider:

Fuel - You need a fuel that will create a lot of energy, but its very important that it burns at a controlled speed. It's often better to have a fuel that burns slowly than one that burns too quickly.

Fuel injection - Unless the fuel starts out in the rocket itself, it will somehow need to be introduced into some sort of combustion chamber. Again, it's important that this be controlled very carefully.

Stability - You need your rocket to be stable, but many of the things that make a rocket stable add drag, such as wings, fins, and adjusting the length of the rocket.

_____

The best way for you to do it would probably be to build something like Spaceship One.

Answer 16

The Space Shuttle main engines are very sophisticated power plants that burn liquid hydrogen and liquid oxygen from the Space Shuttle external tank. They are used for propulsion during its ascent, in addition to the two more powerful Solid Rocket Boosters and sometimes the Orbital Maneuvering System. Each engine can generate almost 1.8 MN (MegaNewton) or 400,000 lbf of thrust at liftoff. The engines are capable of generating a specific impulse (Isp) of 453 seconds in a vacuum, or 363 seconds at sea level (exhaust velocities of 4440 m/s and 3560 m/s respectively). Overall, a space shuttle main engine weighs approximately 3.2 t (7,000 lb). The engines are removed after every flight and taken to the Space Shuttle Main Engine Processing Facility (SSMEPF) for inspection and replacement of any necessary components.

Answer 17

Use a fusion engine. An inertial confinement system should do the trick and is suited for both extraterrestial and atmospheric fly. Unlike weak ion thrusters the sheer power of fusion power can take a ship to space and not just slowly accelerate it after it reached orbit.

It works like this: A small DT pellet is lauched into a reaction chamber where it is hit by a collection of lasers. It explodes like a mini-nuke and propells the ship in the vacuum. If atmospheric air is inyected into the chamber it heats and expands like in a jet engine.

The engineering aspects of this technique are naturally staggering but this is in no way science-fiction. Inertial confinement fusion is an active field of research and i'm sure once it is fully developed we will see progress in space travel.

Answer 18

Well obviously you need the following:

4 inches of string,

The differential from a 1974 Dodge

An empty shoe box

A lemon ( or two limes)

12 lego blocks

and a lightbulb.

Once you get all of these, it is obvious how they go together.
