Build Your Own Jet Engine

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

jgarland79 writes "Have you ever wanted your very own jet engine? Build one at home in your own garage. The guys over at www.garagejet.com have done just that. 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.

  1. Other homebuilt gas turbines by airbatica · · Score: 5, Informative

    These guys are amateurs compared to Mark Nye of Nye Thermodynamics. I realize the page is a little old, but homebuilt gas turbines aren't exactly high tech till you get up to the FADEC systems of commercial jetliners

    Off topic: Ooo... lets slashdot the server to oblivion. It's got MOVIES!

    Kids, if you build your own jet engine, then unlike the nice fellow in the videos, please wear ear and eye protection.

    Especially if you plan on titling one of your videos "Ooops! Forgot to make sure the fittings were tight!"

    Jeez...

  3. 555 timer? by kd5ujz · · Score: 4, Informative

    These guys are charging $20 for the 555 chip. These things go for around $0.90 at radio shack. At first I thought it was the entire assembly, but then I saw the assembly for $50.

  4. Cute DIY, But Been Done: See Links by cmholm · · Score: 4, Informative
    First, full points to the builder for moving beyond the web research stage and getting his hands dirty. For those wanting to play with turbines, but want a design that's ready to slap onto a r/c model, some gents in the Netherlands implemented a cheap design using a smaller turbocharger and an empty Gaz propane camping stove cartridge back in '99. The original links to this design are harder to Google nowadays, now that the designers have gone commercial.

    You've seen the movie, now buy the book: Gas Turbine Engines for Model Aircraft by Kurt Schreckling

    What Kurt's design looks like when built per plans.

    I was the pulsejet "expert" on the Jetcar episode of Scrapheap Challenge (aka Junkyard wars) and the turbocharger turbojet *did* produce a very healthy amount of thrust (probably about 65lbs).

    They didn't win because they had reliability problems and their vehicle was much heavier than our lightweight pulsjet-powered creation.
