Thanks for the advice. I am preparing the model of the engine from my sketches. Now I suspect that it won't be that compact little thing like the Philips machnie..

Another question have just occured to me. I would like the whole engine to be constructed from as few parts as possible. I therefore thought that the inner cylinder or sleeve would be one piece, from the top of the hot side, to the top of the base block of the working piston. The outer sleeve would ...

Oh, thanks :D So the Displacer is actually this long. That simplified it in my mind. I thought so that this amount of consumption would mean a nuclear grade output, but my calculations seem to be correct. In case of the Philips machine: -100W shaft output at low load, which is 100Joules a second, ti...

I thought so, but the wo drawings are from the same engine, and if that is the displacer's top, the length of the two displacers are not even close to each other. In other news.. I have just discovered that using the 1 Watt/ccm multiplied by the internal average pressure in atm gives a roughly corre...

Here's my problem. On this diagram the two cylinders can be seen. But the displacer on this picture is likely in it's topdead, still it has curved line in the middle of it, similar to the top of the cylinder. http://www.moebius-bcn.com/wp-content/uploads/2012/07/Philips-Stirling4.jpg On this picture...

The blocking valve sounds quite satisfying. I thought on a design exactly like the Philips machine, which if I am correct, channels the working fluid out of the piston cylinder, and pushes it down amongst the former, and the outer cylinder. Between the two are the hot heat fins, the regenerator coil...

The size and weight is not a big problem. I have found a stirling designer program, I suspect it is fairly good. It gave a relatively precise output for the Philips, using it's datas. It calculated that if I would use a 75 milimeter bore and stroke, with fairly big dead volumes, I would be able to g...

Hello there. I am new to this site, but thank god not for this topic. I have wanted to make a powerful stirling engine driven generator since years, but now that I have my part time job as a teacher amongst with my studies in the university, I finally have the time, funds and pretension. I find the ...
