Sternmotor

[simsons51racer]

now i understand the system !

[pattyaaron]

Is the crank/hub geared to the an output shaft? 

[Nnoshah]

more explanation pls ?

and for what it is ?

[curtdog223]

dejaviline used a 9 cylinder round motor in the single engine otter through the 50's many are still in use this is a very durable design with alot of torque but there is alot of vibration in radial engines

[xpatriot11]

@curtdog223  The pistons are totally symmetric, it's just the flywheel that would be applying lateral force to the axle and making it vibrate. Could they design the flywheel so that it's centre of gravity was the same as a the equivalent sized disc? Counterweight the inset side of the flywheel, make the outer edge hollow and lightweight? If you put it on a table, it should spin on it's axis... I think it's possible....

[gorgosanma]

The vibrations are kinda difficult to control

[ekaax]

podemos opinar y n es nuestra cuenta!!!!!!!!!!!!!!!!!

tonto de aquel que dejo su cuenta abierta

[mastertrialer09]

Mit so einer Unwucht kann es kaum funktionieren!!

[aetweb]

@mastertrialer09

Der Motor hat keine Unwucht.

Das Gegengewicht zur Pleuelaufnahme ist die Kurbelwelle.

[makingsnsux]

how does the intake/exhaust work on those? a shit load of small camshafts?

[kbuwerks]

Too much movement where the driveshaft assembly would connect. The vibration would be high... Therefore high velocity torque is out of the question.

[JOMSFIRE8811]

se ve bien pro. cool

[dt28469]

Cool a nine stroke engine!

[jake5680]

Correction, a FOUR stroke engine with NINE cylinders.

[gorbi007]

NOT GOOD one tlock must 4 time around here in this motor is not good need 4 sekcion of this prototipe and energy propably must good but benzin out

[bfdpowers]

Wow, spelling?

[dt28469]

Spell much?

[SkaetrPunk777]

that thing would probably have some serious torque to it though, idk about actual speed though

[tommysch]

The simpler, the better.

Keep that engineering motto in head.

[Terminchiator]

less efficent than a classic four stroke

[Nate2203]

if you use it with internal combustion, yes. With external combustion, no.

[Terminchiator]

actually it isn't less efficent, but the piston linked to the fixed rod wil be splatted against the cylinder in about one minute at idle

[Terminchiator]

only because the twitching centre is too big and the acceleration (clockwise and cunterclockwise) is given by the top piston and considering the twithching mass the piston will wear super quick (boxer engine piston wear is caused by gravity!)

[DThompson1985]

now what if they took the gas out and the intake and exhaust ports and replaced them with electro magnets setup with a distributor to turn them on and off with an alternator to power them while it spins.

[cs01ab]

Nice idea but you'd basicaly have a very ineficiant electric motor.

[mastgmc]

gracefull as sex lol!

[seekanddestroy1200]

what machines do they use those motors in

[andimaniac]

planes

[ILOVESPEED25]

Now how do the valves work? =p

I've always want to know!

[oisiaa]

There is a cam plate that rotates coaxially (at a different RPM) with the engine which actuates the push rods.

[teamproevo]

das Ding muss mächtig Kraft haben, nicht?

[chretzel]

did you use constraints?

[SOhio142]

thats exactly how a radial engine works

[LLCoolPass]

radial engine, no?
