I have been reading about mechanical drives for beta engines at http://mac6.ma.psu.edu/stirling/drives/index.html I am having trouble visualising the quantities VAR (Volume Amplitude Ratio) and VPL (Volume Phase Lag) Quoting from the source The volume amplitude ratio, VAR , is defined as the change ...

Hi All I am looking for information about Rudy Kouhoupt's Stirling Tractor. At present I know a build article was serialised in Home Shop Machinist running through the following magazines: Part 1 Vol 15 Nov/Dec No. 6 Part 2 Vol 16 Jan/Feb No.1 Part 3 Vol 16 Mar/Apr No.2 Part 4 Vol 16 May/Jun No.3 Pa...

Hi Ian While you are on the topic of displacers... ... the engine that is currently on my bench is a small Robinson hot air engine. I am taking the leading dimensions from a design published in ME 3803 19 June 1987 page 707-7 by J Robinson. The design calls for a displacer formed from a stack of alu...

Hi Ian I am thinking that I need to redesign the con rod with either a bored diameter that will completly encircle the bearing outer or a two piece design with an alloy ring fitted with loctite to the bearing outer and a modified form of the original design conrod bolted to the alloy ring. As a more...

Hi Ian et al Well I now own one of the torque tube bearings. The exact item quoted by Ian Bradley in his ME (Model Engineer) magazine article. I have to say that I am none the wiser about how the con rod grips the bearing outer race. There are no holes or dimples in the periphery of the outer race f...

Hi All I have been making model engines for a few years since being inspired by Archibald Williams' book Things to Make . I have built three small Stirling engines to various plans published in the British model engineering press. I am pleased to say all my Stirling engines work. Other interests ran...

I am considering building a version of the Ian Bradley Electrically Heated Heinrici engine published in ME 3741 to 3751 in five parts (1984/5). I have sourced the torque tube bearing from the original supplier that Ian Bradley suggested back in 1985. My question is how is the connecting rod (Part O ...
