[IMAGE THREAD] Post your dumb Spacecraft/Rocket Concepts Here!

Recommended Posts

This is an imagethread for dumping your stupid/impossible/bad Rocket and/or spacecraft concepts.

I'll start.

Here is a proposal for a tourism rocket using solid fuel. This is before I realized that Solid Fueled Rockets would be bad for tourists due to the greater vibration.

This was the "Midline Evolution Versions" of the rocket. The Newtron-S is a solid-fueled Sounding Rocket.

Below it, is a "Milkstool", like those used for Saturn IBs during the Skylab Program. This was to allow the rockets to use the same infrastructure.

Newtron 1 is a suborbital tourist rocket, like Blue Origin's New Shepard, but only able carry a total of 3 using a single stage.

Newtron II is used for longer suborbital tourist missions, and carries 6 on a single stage.

Newtron III is used for 3-man orbital missions, and uses 2 solid fuel stages and boosters, but 2 liquid-fuel upper stages.

This was the "Final Evolution" version of the rocket- don't ask me what those things at the side of the 1st stage are- I don't know either, I made this a while ago. The engines at the bottom of the rocket are aerospikes.

When I was a kid I heard about the concept rocket that would propel itself through space using the shockwaves from nuclear bombs. Back then I somehow envisioned it taking off from a launchpad with a thermonuclear blast.

To be fair, the explosion [I]should[/I] send some of the rocket on an escape trajectory.

In an atmosphere, the shockwave would destroy the ship... either that or melt it.

You mean Project Orion? [url]https://en.wikipedia.org/wiki/Project_Orion_%28nuclear_propulsion%29[/url]

It's not really ridiculous, considering you can make interstellar missions with things like this, but firing the drive from the ground is a bad idea.

Incidentally, the Orion Project is rumored to have been justified by a steel plate cap that was blasted skyward, by the Pascal-B nuclear test, at six times escape velocity. Still, using nuclear weapons as a form of launch propulsion is a horrible idea, which is why it's mentioned as a "Dumb spacecraft/rocket concept" I had as a kid. :P

I can't be arsed to draw it at the moment, but this:

1. Get big railgun
2. Put it in space
3. Instead of bullets, feed it a stream of liquid hydrogen.
4. The high current will turn the hydrogen into plasma, and due to the railgun being... a railgun, it will blast it out at ludicrous speed, providing a high thrust and high specific impulse as long as you can provide enough current.
5. Pluto in 5 days or whatever. Tell your friends to buy a telescope.

That is exactly how [URL="https://en.wikipedia.org/wiki/Magnetoplasmadynamic_thruster"]magnetoplasmadynamic thruster[/URL] works, and we already launch it to space. Too bad that it requires a nuclear reactor to run it, as MPD thruster thrust is the highest between all of the electric rockets..

[quote name='mythbusters844']Looks like SNC did it too:

They're sooo stooooooooooopeeeeed in thinking that it mitigates undesirable aero forces and stress during ascent. So stoooooooopeeeeeeed woooow[/QUOTE]

Dream Chaser- Cargo is unmanned, it doesn't need to abort. I assumed Pipcard's spacecraft was manned, so it needed a clear space to abort.

Also, not my idea... but [url]http://nassp.sourceforge.net/wiki/Future_Expansion#High%20Orbit%20Parabolic%20Antenna%20Test[/url]

"In 1966 NASA asked Convair to research the use of Apollo systems to test out large scale space construction projects. One such project was the use of a[I] Saturn V/CSM combination[/I] to deploy a 100ft Parabolic Antenna into a synchronous orbit so that [B]the characteristics of the antenna could be determined under operational conditions.[/B]" [IMG]http://nassp.sourceforge.net/w/images/e/e6/ParabolicExperiment.png[/IMG]

Ah, don't you love the ridiculousness of 60's era spacecraft concepts...

Soyuz launches inside a fairing, and also happens to be the only spacecraft ever to make a successful launch abort. It's not an inherently unabortable situation.

How is that stupid? That's ingenious.

Is there something wrongwith the forums?  all of the posts here show the tags for the encoding to urls and images and quotes instead of the actual embeds.

It was what happened when the forums were upgraded, all the links broke.
