Good afternoon: Does anyone know the formulas and source from them for calculating the maximum rpm for a defined engine with different gases (not just air)? ...
From past performance of such preproduction "advertising' an educated guesstimate would be "IMAGINARY." IF anyone had a viable power producing Stirling engine...
And... that miles per pound assumes the wood heating value is converted to work as effectively as is done with gasoline in an I.C., which seems extremely...
Check out this wood gas motorcycle on the front page of Yahoos "Woodgas" user group. http://tech.groups.yahoo.com/group/WoodGas/?yguid=158599902 It claims to...
Stan, Group, There was a DOE/NASA project which completed successfuly in 1997 that field tested an automotive stirling powerplant. Test vehicles were a Chevy...
Colin As I recall, cost was a problem but the primary reason for program failure was inadequate and unacceptable throttle response combined with excessive warm...
I recently received the following update from Precer. It seems they are not telling us much about their engine; but at least we know one thing it is not. jc ...
Colin, I was the chief engine designer on the predecessor to that project (where the engines were developed, back in the 80's with about $110M of your tax...
John Could you comment on the throttle response and the warm up time issues? Lee ... From: John Corey To: sesusa@yahoogroups.com Sent: Thursday, December 13,...
Sure, Lee. Throttle response was actually better than the original engine in the Celebrity. Mind you, in those days 0-60 in 15 seconds was the norm, and...
This came to my attention from a NASA Tech Brief's email from 12/18. I have a feeling that if it does work as advertised, it will create some new ways to...
If I remember correctly, SES bought the engineering company WGA which was a couple of very experienced mechanical engineers with extensive experience in dish...
... A bit late coming in on this one but I haven't logged on for ages! Anyway, I have in front of me a drawing of the Robinson size A4 as manufactured by...
list, On p.159 of "R & SE" -Organ, I find this: Organ's empirical curve fit to real engine data: rpm = 14.16 * SQRT(((Rgas)(Tref)) / (Lref)) Incidentally, the...
MP, I'm sorry but I don't know exactly what you are referring to. Could you explain what you mean a bit further and perhaps point me to the sheet/cells that...
Tom, list, ... Then solved for w (omega), the angular frequency of the cycle. w = (Nma/ Lref) *SQRT(((Rgas)(Tref))) f = w/(2 pi) and rpm = 60 f so, rpm = 60 w...
MP, Well I see what you are doing. BUT, I still do not see why you are doing it. Two of the basic parameters of Vsw, Pressure, RPM, and Gas are set by the...
Tom, Okay suppose you're designing an engine, and you enter some arbitrary values for swept volume, mean pressure and gas type. What value do you enter for...
Tom, I hope I wasn't getting too "testy" there, sorry about that if I was. I'm trying to read Organ, (starting with the words! :-) ...I'll see what I can find...
MP, I wrote a multi page reply but then I couln't get my computer to post it. So here is the short version. 1.] The GCS is to estimate the form the heat...
MP, The GCS is for calculating the HEAT EXCHANGER geometry. It is not a simulator. If you enter swept volume, mean pressure and gas type that is all that is...

Say I have 2 hypothetical engines. One is IC; one is stirling. I know the output of the IC engine (it says on the side) and I want to know roughly how much the...
