Perhaps you are right. Dimensions of my engine barely corresponds to Mingfei Chen(2.19, from him book) formula (1-Tc/Th-Ar/A)*L*A/(lp*Ap) < 1, where is Tc cooler temperature Th heater temperature Ar cross section area of displacer driving rod A cross sectional area of displacer L 1/2 stroke of displ...

I've done a little engine. When it ran on little candle(about 45 Watt) before full warming-up it rotate 3-5 or 10 times enough quickly then stopped and began reversed rotate about as. After total warming-up it rotated in one direction with gud speed(240 rpm) but after 3-5 minutes just very qucly (2-...

Does anybody use HDD Voice Coil Motor like linear alternator? How easy to connect working cylinder and VCM? Please help - where can I get example?

More thanks, I guessed about this factors, but I wait opinion of experienced builder engines with this type of displacer, who can give a quotient. In my opinion, it is about 5-8, depending of a temperature and speed. Perhaps every time not less than 5, but interesting a length depending of speed - 1...

Does anybody have experience to determine compliance approximate dimensions between steel wool displacer and normal? If swap volume of the normal displacer is one what is the swap volume of the steel wool displacer at the same sizes?

More thanks, now I fixing some troubles with bearings and flywheel, use the available materials and possibility of accuracy.

Ian, y're right. Now I have some troubles with building little Ringbom. First - calculation the spring, second - calculation the flywheel. But I'll solve them most quckly that registration.

Finally, after one year trying to register and a lot of attempts I'm here!
