Wooden Demonstration Model of Radial Engine

[JSFER2]

so how is the power transferred to wherever it's going?

[carbidedemon]

fine example. however ignition in inacurate every once in a while

[nikhilphillips]

In this kind of engine, how is the air/fuel mix metered to the individual combustion chambers? is it like a two stroke where it is crankcase-induced? sorry, i'm an engine enthusiast but new to these 'rotary" engines.. not new to the Wankel though.

[Daevo69]

THIS IS A ROTARY ENGINE BECAUSE THE CYLINDERS ROTATE

[adonsang1]

ahhhmm piston # 2 does not fire???... anyway, good work. impressive.

[ClefDeDavid88]

if i were in a crowd of continuous talking like that with my mind fixed on something so interesting I would literally go out of my mind.

ROTARY ENGINES DONT HAVE PISTONS

THE TITLE IS RIGHT THIS IS A RADIAL ENGINE

[fairyheli2]

@666ShoopDaWoop666 google gnome rotary

RETARDED COMMENTS

People that say that this is a rotary engine and not a radial engine are fucking retarded

The title is right THIS IS A RADIAL AKA STAR ENGINE

[direktorpresident]

@666ShoopDaWoop666

You are ignorant, rude and incorrect. It is a rotary.

[666ShoopDaWoop666]

@direktorpresident

This is awooden model from a propellerplane radial star engine

rotary engines are from japanese cars and ROTARY ENGINES DONT HAVE PISTONS

and i can see 9 pistons in star shape so its a RADIAL

[direktorpresident]

@666ShoopDaWoop666

Perhaps you might like to search for,say, the Le Rhone rotary or its copy the Oberursel, thousands of examples of which powered aircraft of both sides in the First World War. You may be thinking, most appositely, of the Wankel with its trochoidal piston. To say that rotary engines don't have pistons...?

[666ShoopDaWoop666]

@direktorpresident

o yeak now i found it , ok you are right.

but wankel engines are also called rotary engines so i was confused

Wankel = rotary pistonless engine

[direktorpresident]

@666ShoopDaWoop666

No worries! I was rude because you threw in a few EFFS and called people retarded! You have demonstrated that you can admit when you are wrong - you will go far. :-}

Cheers

I think one of the 'spark plugs' has stopped firing

[inurkiewicz]

That's completely different to how I thought it works.

[mdbouch]

BTW - the builder's name is Roland Gaucher.

[Bamchucknorris]

thats a rotary model, but i learned how they work now :)

[Mrpantymelt]

its a rotary nice model

[schlusselmensch]

Many years ago my father, who was an engine tech in the RCAF, talked to an old German pilot from WW1 about the airplanes he had flown. One of the surprising things the old boy said was that often the rotaries would have no discernable vibration when running at a steady speed. All the rotating elements could be balanced very finely. If you concentrate on the engine cylinders and crankcase or on the crank, rods, and piston it dawns on you that there is no reciprocation of components going on.

[angryace13]

thats not a radial engine thats a rotary piston engine, in a radial engine the crank rotates and the block is stationary, in a rotary piston engine, the block rotates and the crank is stationary as shown.

[Synaps4]

This guy/girl makes an excellent point.

[Anxo512]

yes, it looks like old gnome engine

[dawg1157]

nicely said

[GGigabiteM]

Something be wrong with that model; every other rotation, it skips two cylinders instead of just one. Probably a logic or mechanical error.

[DragonFlyback256]

GGigabiteM, yeah, it must be something with the contactor, wiring with that one or the bulb / LED itself, it just doesn't light up.

[player1diao]

it is true.

[Melaneimoon]

i don't think the piston housings should be rotating...

[nemo1620]

Early engines for aircraft often used engines with rotating pistons -- so-called "rotary engines" (see Wikipedia article about them). Instead of a heavy radiator, the engine was cooled by the flow of air.

[Melaneimoon]

Wow, I didn't know about rotary engines. Pretty impressive.

[xKmotx]

This would be a "rotary" engine, not a radial.

[BWA00]

Sorry, I have the two types confused. When I hear the term "rotary" I think Wankel.
