Lynn, regarding your drawing of the open chamber muffler, were there
        also
        perforations in the transverse bulkhead plate at the aft end of the
        expansion chamber (supporting the front end of the perforated main
        tube)?
        You should get an award for keeping that heat tape on for that
   long.

        Yes, here is a picture jpg.jpg, sort of. All I have is MS Paint.

        That is real talent Lynn. You should get yourself a copy of Rhino.

           I have a full working copy of Turbocad if you want it.

           Dan Michaels

        Giving TurboCad away seems too popular a sport. I have that as
   well. I
        didn't like the small working area.
        I have it. Google has a free trial of their program, and it is
   really
        nice, But you are on the clock and it dies. Then you need to
   buy into
        it. You can make a shape and rotate it any number of degrees in any
        axis. Very advanced. I will look at Rhino.

        If you sign up for a local college course you can get a huge
   discount
        on Rhino and there is no time limit.

        BTW I would love to see a 3D of this last jpg Lynn.

   Lynn,  Curious about your Mooreover engine.  Do you have a functioning
   proto?  Is that similar to the dynacam?  Whatever happened to the
   dynacam?  Last I heard was some time back when Piper was working on /
   with it.           Dave D


No, No pieces were ever built. That was just one of the fantastic ideas
that came to me when I should have been working for uncle sugar.

The Dynacam is a real engine and was certified for aircraft use during
WWII. It was not used because its best feature was that it had 1/3 the
frontal area of a conventional aircraft engine of the time. Piper had a
small one mounted on a light twin for a while but the Dynacam people
could not get along with the program and another "greatest airplane
engine ever" never got launched. It can be scaled without difficulty.
Big enough for a Mustang, or small enough for a Piper. It is simple. It
could be built with no plain bearings, it is smooth as silk. It still
has a very small frontal area. It can be manufactured with conventional
tooling. And if you are really interested, the patents ran out years
ago. With modern materials and sealing systems it would be even better.
Piper was not wrong. They just couldn't get the project going.

   When at the Air Force museum I always stop and look at (the very big)
   cutaway version they have there. A reclining pilot and a Dynacam
   engine and half the frontal area, The Mustang could have been a
   2,000 mile range 575 MPH fighter.
