Btw., the Oberursel Engine Company (Motorenfabrik Oberursel) is still in business, after Deutz and BMW, they are part of Rolls Royce since 2000.

I love the sound of a Rolls-Royce Merlin, but nothing compares to a big radial. Hearing a P-47 or a F4U and B'17 on take off sends chills up my spine.

[@clearcreek69]

Gotta love Pratt & Whitney

[@shortribslongbow5312]

Love those round engines. :o)

[@Pwills]

You mean radial engines Or rotary engines

[@bugz000]

@@Pwills no, round.

[@eliasaxelson1411]

This rotary engine is a crazy engine, I don't understand why it was made?

[@wallnut886]

Back in the first world war they didn't know how to properly air cool radial engines, so they just made the whole thing spin to keep it cool

[@Workerbee-zy5nx]

Awesome engines. The semi with the rad on back should fire that engine in traffic, it might keep tailgaters away😂😂😂

[@scottmichael3745]

Just fabulous! Loved it.

[@johnzangari3432]

I think the rotary engine would be the engines with the rotating cylinders.

[@paullubliner6221]

At 0:43 THAT is a LeRhone 9C, (80 hp at 1200 rpm: Nieupot 11, Sopwitch Pup, Dh2 etc.) It is NOT a Gnome Monosoupap. Can't you spend 15 seconds looking this crap up?

[@diegomr6969]

ROTARY ENGINE TOO DANGEROUS FOR ME

[@daviddishon642]

Rotary engines hadn’t been designed in ww1

[@waynepurcell6058]

Rotary engines were designed in the 1890's. You're probably thinking of the WANKEL engine which came out much later and "technically" isn't a "rotary engine" at all. Rotary ENGINE means a rotating ENGINE. A Wankel doesn't rotate, it has a rotor inside of it that rotates.

[@TinkerToby]

Shows what you know 🙄

[@tonyelliott7734]

Rotary engines are an engineering wonder...

[@Lykapodium]

Gotta love the rolling shutter effect

[@hotrodray6802]

Nothing like TWO 2800s at full throttle on takeoff 👍👍👍😎😎🇺🇸🇺🇸 A26b

[@brentdykgraaf184]

Ahhhhhh there it is....radial fix for the day ! Thank you !

[@skaldlouiscyphre2453]

I won't be happy until I find a Fokker with a 13B swap. _BRAPBRAPBRAP_

[@xyxxyx4883]

R26B would br much better

[@knobsdialsandbuttons]

What speed does the rotary engine spin ?. You'd think the centrifugal forces would tear it apart, even quicker than the wooden propeller ! 😮

[@Allan_aka_RocKITEman]

Great video...👍

[@arahanterakhir7714]

All the good engine will be the propeller blade turning counter clockwise otherwise the engine consider not good enough

[@BarefootBill]

Amazing difference between the WWI and WWII engines!

[@westcoast3595]

Radial was an engendering marvel.

[@Michael-um5pd]

I just love the sound of them all

[@UtahDelaCruz]

If you're firing up an air-cooled engine without a prop, how long does it take to overheat?

[@egustafson]

I'm gonna say pretty darn fast buccaroo

[@musicbruv]

rolling shutter effect ruins the video.

[@mikepxg6406]

All compromised. Never going to beat a Merlin Engine.

[@davekreitzer4358]

To much energy spent and not enough flying !!! 🧐🥴

[@daviddishon642]

I didn’t see a single rotary engine in the bunch

[@UtahDelaCruz]

You're talking about a Wankel rotary engine - like in the Mazda RX7. The term "rotary engine" pre-dates the Wankel and was applied to any engine where the cylinders were distributed evenly around the crankshaft. Engines with stationary cylinders came to be known as "radial engines".

[@stupitdog9686]

@@UtahDelaCruz.... Oooh ..... I wuz wondering about that too!! So the early "rotarys" were the ones where the cylinders rotated with the propellor !? That musta given major gyroscopic control problems given all that mass rotating at the front of the plane !!!

[@UtahDelaCruz]

@@stupitdog9686 I wondered about that. My guess is that this was taking place so early in the development of aircraft that if the engine was properly balanced, anything else would just be perceived as wind buffeting - rather than gyroscopic effects. Hard to say - not many of those types of aircraft around anymore.

[@stupitdog9686]

@@UtahDelaCruz ...Yes I suppose so....gyroscopic effects where probably unthought of at this time ... hard enough to understand now !!
