In reality this configuration would not work in real life because you need to have an odd number of cylinders to get even firing angles. If there were a radial engine with 4 cylinders the firing angles would be uneven. This would result in it sounding like a Harley, which is awesome. It would also result in lots of vibration and a sine-like torque delivery, both of which are not wanted in an airplane.

But this one is 2-stroke, and this is also Algodoo, which means I have no reason to care about that :lol:

I also somehow got this to resist a 3500nm brake at like 800rpm and I got 390 hp. I find that hard to believe...

I don't see why you say that this wouldn't be possible to make irl. You can make it just like an i4 (2 pistons at bore and 2 at stroke). But whatever
Your calc is completely messed up for sure. You should take s_noonan "Torque vs rad/s" (i think) scene, which is in his 2nd or 3rd page, put this at 100 Hz and try until it gives you the highest measure- but this thing hasn't got more than 15 hp at 100 Hz for sure. I can bet;)

That's cause all my engines run like shit at 100hz. Except my rocket engines, which I design to run at usually 100 or lower (I've made some that run like hell at 60 for people with lower-spec computers, but it never made it here)

I'm pretty sure my torque calculation is all screwed up too. But, I'll put this in s_noonan's torque vs rad/s scene and do a reupload, if it's fine with him.

It won't be bad for him if you just give credit

Ok, cool. I'll try that.

Also, what is this friggin multiplayer-piano thing you guys keep talking bout? I didn't know all you guys were secretly pianists...

Nope, I never played piano, but PC keyboard is not the same thing at all (unless you can use MIDI on your piano...)
Go to multiplayerpiano.com/algodoo, forget the other one ;)
