Needs polishing, but it works at 60 rad/s "as is"!
Made in 3 hours or less. I think it can get a wrong timing if you leave it some time, but it is OK for the first 5-10 minutes.

Using Gent's old gun engine concept, inspired to make one of this by lethalsquirl

My first quad rotor wankel (Maybe first in Algobox, idk)

Please comment and rate
P.S christer, how do you measure power and torque of algoengines?

v2: Improved look, and changed killer position to give more speed and
some more torque.
v3: Added more density to the spawned balls and gears

AWESOME

now I get to work on this :lol:

You need to move the whole ignition and gun thing up a bunch similar to my version of squirl's engine but it will prolly over rev :lol:

You are missing a bunch of the available power stroke

Yes the timing is very crappy

I had overrevs of like 110 rad/s like it is now

I think I will try building a 3 rotor in a more realistic scale from scratch
Wish me luck :lol:

100 RAD/s target

PS on measuring power,
to find horse power create a brake on the engine that limits
it to whatever speed you want to test and then convert the
N/M value to foot pounds, multiply that by the RAD/s converted to RPM and divide by 5252 = HP
HP= tourque in foot lb x RPM / 5252

OK thanks

Our scale is a bit weird, I know (my engine is 7*6m)
P.S later I'll start making a 1 rotor (just for test) collision Wankel that will be the crappiest thing I'll ever do :lol:

Old wankels didn't even get to 20 rad/s, i'm waiting for yours even if i'm not sure if you'll get to 100 rad/s ¬¬

Awesome update looks very nice :tup:

wow really awesome job. totally puts mine to shame :blush:

I'm working on something that should be way better than my old one, and a lot more detailed :lol:

I use N/m*RPM/7121 same thing, just skipping the torque conversion:)
I have been fiddeling around with an scripted dyno thing that does all that for me, i just choose what RPM i want the Engine at and then it brakes it down to that RPM and calculates hp.
I would release it but it feels to beta yet, i could send it to you guys if you are interested at having a look? im sure you would figure out how to tune it for different Engines:)

I took v1 of this Engine, scaled it down to 10% and upped the density of the rotors, spawn balls and c-gears and it made about 10-11 hp@550rpm wheiging 67 kilos, but v1 is to unstable. Something interesting i noticed is that it looses Power fast under ca 300 rpm so it kinda behaves like an wankel(high revving)

I will look at v2 later!

Thanks! I'll try to make me a dyno later to test my engines.
Now I'm making a car that actually had a quad-rotor!

Nice!
