Stirling Engine Help

  1. Nov 29, 2011 #1
    I'm designing a stirling engine for a high school engineering project. I need to know more information about them though before I start machining out the parts. I looked at Wikipedia and a few other sites, but I need something a little more in depth. I'm looking for a good stirling engine book or perhaps a the contact info of a knowledgeable person who is willing to check out my designs and critique them or any other info related to stirling engines that could be helpful. Thanks.

    As it happens they are easy to make and there are a lot of sites providing schematics and notes ... did you google for "how to build a stirling engine"? There are even videos.

    I had a look for projects specific to education needs:

    "test tube stirling engine" is another excellent search term

    of note:
    ... have a look at Aphonse Vassalo's (scroll down) - he has a lot of different designs.

    But what would help you most is probably a report from someone doing the same thing you are:

    I suggest you make a Gamma engine. Displacer in one cylinder and piston in another.
    Its a simple layout- therefore easier to make
    Do not try to innovate on your first engine. Copy something. When you have got that working you will have learned a lot. Then innovate.
    Make the swept volume of the displacer twice the volume of the stroke of the piston
    Then there is a good chance that the heat will be able to push the piston
    Go to Airpot.com and ask for a free sample dashpot.
    This is an excellent pyrex cylinder with a superbly fitted graphite cylinder
    The secret of Stirling engines is keeping the friction down - and freedom from leaks
    Have fun
