Thank you! I discovered this motor in an issue of Automotive Quarterly which covered the Adams Farwell. This car had either a three or a five cylinder rotary radial in the rear, driving the rear wheels. The Rotary Radial Piston engine was instrumental in the advancement of early aviation. The type was sufficiently powerful and slight enough of weight to allow aircraft designers to make sturdier machines and advance beyond the box-kite type of structures possible with other engines. This engine type drove aviation for a decade.
Either it had a rotary engine or it had a radial engine. They are separate types; defined by whether the crankshaft is fixed and the cylinders turn around it (rotary), or the cylinders are fixed and the crankshaft turns (radial).
@@kmoecub It was a Rotary Radial Piston engine. Not the first, but very early. It spun under the rear bonnet in a horizontal plane. The engine had variable compression for throttling and the bay was shaped to collect the castor-oil thrown out of the exhaust ports.
А, может быть, РОТАТИВНЫЙ? Это двигатель, где блок цилиндров врашается в сторону противоположную винту.. Это была, очень, распостраненная схема двигателей на " заре авиации"
When I'm in Norman Wells, Northwest Territories, the Buffalo Air radial engine DC-3 cargo would shake the town on take-offs. But what a sound reminicent of every day WWll airfields!!!
If you are referring to the rotary engine it is far lighter than any other type of engine at the time, it required no extra cooling at any time, on ground or in air, and was far less vulnerable than a liquid cooled engine.
@@user-mt1uw8ks9c Because the crankshaft is stationary and the crankcase /cylinder rotate the crankcase does not have to be robust enough to take the stresses, so it is a very thin cylinder with the cylinder barrels attached, this makes the rotary a very light for power output engine, ideal for aero use, engine revs were controlled by cutting out some of the sparks on the 9 cylinder ignition, that is what cause the stuttering sound when one is flown in an aeroplane,the only limit is that the capacity is limited by the fact that it induces gyroscopic force to the airframe, but in 1912 an engine with this much power was just what was needed I hope this makes sense.

@@453421abcdefg12345I've always wondered if part of the advantage of the rotary was the mass of the engine acted like a flywheel to help keep the engine running smoothly given the primitive ignition system.
@@carbo73 You're welcome the whole concept broke my head at first until I thought about other ways of delivering fuel in other engine designs. It still blow my mind how the designed and built those engines back then.
The main problem with a rotary engine is there is no throttle, it runs at full speed and then one needs to interrupt the ignition (coupee). It think that a rotary would also create a very high level of tourque when flying.
Yes you are quite correct, the early rotary engines were throttled by cutting out the ignition to some of the 9 cylinder, but later rotary engines did have a throttle device. The torque was used to advantage in combat, it gave a much tighter turn in one direction.
Oh Jesus! The first thing we learn when learning to hand prop, is stand behind it, so if it starts, you get slapped by the trailing edge, not bashed by the leading edge. You're doing it wrong! Scary.
oh wow! that’s not too dangerous is it? I never understood why for awhile the rotary i.e. engine rotating WITH the prop was ever even conceived! The heavy engine would result in very dangerous even poor throttle response and would have very serious gyroscopic effec also dangerous in a light aircraft!
rotary engines were light for the power they produced. Sopwith Camel pilots were well aware of the gyroscopic effects of the engine and would purposefully turn into the gyroscope effect to turn faster than otherwise possible. That ability combined with the massive power and light way made the Camel far more maneuverable than any other WW1 aircraft, which in turn allowed it to down more planes than any other allied aircraft.
Rotaries are interesting but I love the sound of a radial.

That's not a rotary engine shown on the Sopwith Pup, it's a radial

that's a bingo
Thanks
4:04 my soul left my body 💀
IÄm no aviation expert, but the "plane" in 1:50 seems to miss something very crucial.
That's what I thought too but I just can't put my finger on it 🤔
I am an expert and it is missing the windscreen. It will never fly without it
@2:22 you can hear what eventually was used for the hyperdrive failure on the Falcon.
The pup footage appears to be a fail on the editors part.🤔 it looks to have a more modern radial installed.
Looked a lot like a Rotec Radial from Australia.

Those rotary engines are utterly mad spinners.
Extremely powerful engine
Think there both cool ,neat and interesting Would be cool on an airboat but may want to spin the boat around 👍🙃
The Jacobs sounded good during high throttle.
I thought the same. It was nice.
Imagine the gyroscopic presession flying with a rotary! All of the tail feather inputs would affect everything. 90 degrees later!
Suhbanallah...God Bless You
Love the sound, I could listen to their music all day long!
The Sopwith Pup at 1:47 is not a rotary engine
Great video...👍
Id like to see a Napier Sabre starting up. Sleeve valve type engine.
Woo hoo! That looks fun! 😂
The sopwith pup appears to actually be a radial engine, the crankcase doesn’t turn on a radial engine
Интересно, интересно.
Pity there wasn't a Bristol sleeve valve engine in the mix they sound so different to a poppet valve radial
Wonder what the engineers had in mind when designed an engine like this. 😊

Why making it rotary, would make them lighter?

C'est peut-être un moteur que mon grand-père a construit !
engine go brr so and plane go whoos so the and make brrwhoosh
I've always wondered how's delivered the fuel to the cilinders, in a a rotary engine? Not by lines that's for sure.
Kind of like a two stroke through the crankcase. In the first engine you can see it only has one valve.
many thanks, it makes sense@@ToolofSociety

Why?
The Problem is you're totally wrong also rotary Engines have a throttle
Where on earth did you hear that? Its wrong, I recommend reading some more material.

@@markusjung2087prove that then.
Cool
Sopwith Pup was a radial, not rotary.
That looks like 2x4's and plywood .

Which ones do you like most, Rotary or Radial Engines? :)
I love both!
Rotary 👌
Love both, but Radials are top for me.
