Build Your Own Jet Engine

Posted by michael on from the burning-down-the-house dept.

Their jet engine is made from an automotive turbo, spark plugs, and some scrap metal. I have made a mirror site here." We've had a couple of previous stories about a guy building pulsejet engines - the type of engine described above is a turbojet.

    The upshot is that you can't use a jet engine to get into outer space, only a rocket engine, because there's not oxygen up there for a jet engine to burn enough fuel to make enough thrust.

    Wrong! You *can* use a jet engine to go into space. You just need to accelerate to 11,000 km/h, the escape velocity (lower if you are at higher altitude, or just want to go into orbit). You can even go into space with a (really big) cannon.

    Your jet engine will come crashing down.

    And if you do reach space, you will be wishing that you did come crashing down.

    It's interesting how price isn't an obstacle when it comes to building your own jet engine. The average person may think that it's impossible but these guys have proven that you don't need high tech equipment, just a couple of basic tools to be able to build something so out of the ordinary.
    These guys haven't proven that you can build your own jet engine, they've proven you can modify a turbosupercharger into a gas turbine. The Really Hard Part is the turbines, which they *bought*, as opposed to being made.

    It's cool, it's semi impressive, but it's not what it's hyped to be.
