Meanwhile, I apologize if I did not understand (my english is very poor) you're restoring an engine with parts missing, and then you had what was to size. Have patience. I step directly to the things that I consider important and on which you disagree. I make some considerations. 1) The engine is an...

True Longboy, absolutely true, I'm no lost in calculations, was only to do answer and to do do consideration on (in a good way done, and interesting) "provocation" of your friend. For this (less calculation: make) also I recall the book "Making Stirling Engines" by Andy Ross; tha...

Ian, The engine is not beta, is a gamma with parallel pistons/displacer (the beta is strictly coaxial, there you have problem on friction and lubrication coaxial stems ans also complication in leverages). (The difference alpha against "beta-gamma" is that in the first the working pressure ...

Genoastirling is an initiative born near Genoa University few miles to my home, but now trasferred to Milan (Milano). I do not know the engineers. The engines (clearly prototypes) are well designed, but in order of informations contained in the Ross book, and for my esperience shoul be improved. An ...

Thank you for your comment that allows me to agree with you, make my comments. and give you my conclusions, that I think affect you, but also others. I agree with you that many involved in the usual engines "wire and tin cans", or nearly so, and do not make engines that produce a little wo...

We are interest to discuss about, if you like and have interest.

.....and industrial archeology, the new one is somewhere else.

I'm Ferraccio from Italy. Compliments for your remarkable work, in materials and in images! Before to give answer please a question: becouse this title for the discussion? We have supported strange theory-men for many time, without delete. Property of delete is only in hands of Coordinator, and this...

If Walker has a necessity to precise this, may there was a lot of confusion; in fact the patent of R. Stirling was only about the regenerator, many hot air engine in closed cycle was yet existing in 1816.
I'm in accortd with you.
Ferraccio

I'm not in accord about the name, the use of the name was resumed as was resumed the scheme of the engine. The brother of Robert Stirling was an engineer and with Robert (the inventor) found a Company that built large engines, called "Stirling Engines" that have at first good commercial su...

Thanks Ian, you're very well informed!
I read that with the German occupation of the Belgium, during the war, the prototypes and the drawings were found by German soldiers, but were considered to be related to a strange design of a compressor and were ignored.

For Ian, yes Philips engineers exhumed in 1950 the Stirling engine forgotten for many years, but the engine had good success with that name in 1800. The reason for the design of the "bungalow set" was the first development of civil aviation in 1930-40, (primarly for postal service) the con...

For Ian,
yes the tube frame of the engine is the reservoir! The frame has to be filled by compressed air before stops the engine, and allows the followings start.
The start procedure (may be is dowloadable) is not at all simplex.

Yes Aviator, with solid sealings, as gaskets and flanges, there is no loss of gas.
When the gas is air, gas leaks are contrasted by a compressor, but it is expensive to build and subtracts power, in the case of specialty gases such as hydrogen or helium, escapes are not eligible.
