    People have been building whacky aircraft for a while now - checkout the X Planes...X-24B.



    Steve Austin flew an X Plane.

    well I have no clue but I guess the rocket was the easiest way in the past to get something in to space. I can only assume flying upwards in to the sky in a more or less straight line is not the same like flaying with a plane from A to B.

    I missed the part where it says it breathes air. It's just going to fly off like a plane and then hit its trusters, no?

    Meh. I'll applaud if they do it. I've heard so many visions for the (near) future in my lifetime. Maybe 1% actually left the development stages.

    well according to 2001 we are a bit late anyway. Should be already at Jupiter. Owning lying murdering computers with red oculars and meet some alien-block floating in space.

    So far. We did not even reached the Mars. Fuck it. We don't even have a moon station yet. We are really pretty far behind. They should speed up the damn process. I want to reach Sirius still in my lifetime! That or they should dig out the Star Gate at least.

    How about this thing here:

    Just put a hyperdrive into it and it's good to go. :D

    I love this "potential" Russian aircraft from the 1930's. I think I've seen it in a few manga movies.

    Odds are that this will be less fuel efficient than the Saturn 5, not more. The thing that makes this desirable is that it's supposed to be fully reusable.

    The real question is will it be less expensive than the Saturn 5 rocket? The Space Shuttle was actually a failure because it was more expensive and couldn't really do anything than couldn't have been done with a Saturn 5.

    Could they have picked a worse name? It's name sounds to me like a portmanteau of Skynet and Cylon. It's like they're begging this thing to kill us all.

    Anyone who can't see the flaws with this needs to get their head checked out.

    I think one of the issues you have with "space flight" is that an usual plane actually gets much of its impulse by the Aerodynamics of its design which give it some upward tendency so I guess one can save a lot of fuel by the laws of Aerodynamics and designs which work better with it which I assume probably do not work in the same way when trying to leave the earths orbit as you do not have any other impulse then the push of the rockets engine so one has to create a steady force that lasts at least enough to get the rocket/space craft in to orbit.

    I mean if all the principles of the usual Aerodynamics we know from planes and their engines would work for space crafts then why not simply design a glider which does not need any engine at all to fly and simply use that for space travel ? Yeah well ... it seems there is a lot more behind it then just that.

    By the way the design of the object is not that important compared to the impulse. I mean in space you do not have to worry about aerodynamics anyway and for flying upward in a more or less straight line the best design is simply a rocket so far. So you could keep probably the same rockets like we have today but get a new revolution by an engine like Ion thrusters but with a much better energy coefficient then today's usual fuel/chemical based rockets. The question is how to get some energy source which is light enough and yet has enough energy to generate a steady output. I assume the speed you need has to be generated somehow either by the boost of Oxygen/Hydrogen/kerosene or other forms like Ions. I mean the energy you throw out has to come from somewhere and there is a certain limit with every energy source.

    - I might be talking out of my ass ... because I actually have no clue. Just what I assume.

    The principle is to make a reusable space transport.

    To make it reusable you have to make it able to fly in the atmosphere, so it can land safely.
    To achieve this (except for the last minute D-Dalus which could be a potential contender), you have to give it a plane shape. That's why planes come in the shape of planes, right ? Otherwise they couldn't fly. That's aerodynamics right there.

    So, no, a rocket wouldn't be the way to go. Even if we could manage to make an object of the size of a shuttle, and in the form of a rocket, to manoeuver and land safely in the atmosphere, it would still be way inneficient in terms of fuel efficiency : that means it would be a gigantic waste.

    See, there's a reason they've come up with this shape.

    well it does not help though to have a space craft shaped like a plane when it tends to use more fuel the na space rocket to say that. Not that such designs do not have some feature. With new technologies and more efficient engines. Probably anything could be possible.

    The problem with having spaceships take off like an airplane is that they need to travel to a few km/s in order to stay in orbit. This speed is almost unreachable in the atmosphere, and it requires a lot of fuel to attain. This means that, afaik current space ship design has them take off vertically, to exit the atmosphere as quickly as possible, and then to accelerate to higher speeds. Taking off like an airplane means carrying a lot of fuel with you through the atmosphere, on a longer flight, until one gets to the lesser dense outer part of the atmosphere. This could be costly fuelwise.

    as crazy it might sound. but if it works and is efficient ? Why not.

    I mean they could make it even work completely on solar power no ?

    Who knows what kind of technological marvels they will discover in the next 50 years !

    It does work but it's definitely not viable yet, even with carbon nanotubes it would still cost trillions of dollars to build.
