Re: Low Temp Stirling Design - Low Weight?

Hello All, Another update, another collection of questions... I've attached some rough drawings of what we're doing so far (sorry, they're a little out of order) First, Airflow: I'm worried about leaving enough volume for air to pass between the cylinders, but i don't want to leave too much. Second,...

Re: Low Temp Stirling Design - Low Weight?

Hi again, sorry it's been so long - all kinds of busy all at once... I saw a post somewhere on here about somebody's LTD stirling (might have been yours, Ian), about 6 inches across or so, runs on a cup of hot water. Does anyone have any thoughts about the feasibility of scaling up a design like tha...

Re: Low Temp Stirling Design - Low Weight?

Thanks, Ian S C. Very insightful. I guess the biggest question is in regards to power per weight - does one big engine create less power than many small ones, or are there too many variables to answer that in a meaningful way? Honestly, I would be happy to get an engine running by December. It's jus...

Low Temp Stirling Design - Low Weight?

Hi all, I haven't found any threads talking about this yet, but feel free to refer me there if I missed anything. I'm a third-year engineering student building a stirling engine with a team. The plan is to drain some small ponds with a stirling-powered pump. The trick is that it has to weigh less th...

Re: "Hi...We are new here!" First posts here (or anywhere is OK)

Hi all,

I'm a third-year engineering student, and I'm building a stirling engine for a mechanical design project...
I imagine I will have my fair share of questions.
