My 2nd Beta Stirling engine, for SPACE, New delhi

hi great work i too am making one and will soon post it.

How much heavy is the flywheel? thanks.

@asdfkjaskldalsdfa

The flywheel is very light, just a plastic wheel from a toddler's bicycle!

do you need alot of machinery for this?

[subirbhaduri]

@TheSquirrel212

Hi. Not at all. the whole point was to make these engines very easily, as a kit so that anyone can make it. however i have used some higher wattage soldering gun for making the fins, rest is all simple machinary, drill machine, hack-saw, etc...

[TheSquirrel212]

@subirbhaduri I dont have a vertical drill only a normal one

[subirbhaduri]

@TheSquirrel212

HI. do not worry, that the normal drill will do. i do not have any plans or drawings else i would have shared it with you...

[subirbhaduri]

thanks! lesser stroke length of displacer would reduce the side forces on the power piston, and hence have lower friction. but i would loose on account of volume of gas heated/cooled. To compensate i might have to make the piston cylinder dia different from the main cylinder, isnt it?

Maybe you can try to increase the diameter of the cilinder. The longer stroke increase the angle of attack of the forces: more side force = more friction and less efficiency.

But nevertheless, building a beta is much more challenge, than a gamma.

By the way, I have built a gamma ultra LTD, power stroke is only 4 mm, displacer stroke is 6 mm.

hey brother plz help me.

actualy i want to build a sterling engine 4 my third year project bt i dnt know frm where 2 start.plz help me

i knw almost every theoritical thing abt stirling engines...........

[csizmarikg]

Keep up the good work!

Try less stroke length.

Cheers
