Well, all of them were rotary engines, as you well know. Oil consumption was “complete”, as all oil went out the exhaust: a total loss oiling system. The oil also carried away engine heat. The only engine I know of that appeared to be a 4 cylinder radial is actually not. All pistons fire at the same time in that engine.
These are rotary engines, the cylinders spin with the propeller.
The rotary engines had no throttle to control engine speed....They ran wide open but speed was regulated by a kill switch which cut off ignition to the cylinders giving them on off sould....
That's true, that the earlier model rotary engines, had no carburators and no throttles, there were some later models that did.
Ronald Green Yes, was the case, and when they start up and run, ice forms on the crude elbow that channels the fuel through the hollow crankshaft and into the crankcase! A bit of a 2 stroke meets 4 stroke arrangement! Cheers
А звук какой, красота, ухо радуется!
Awesome piece of history
Can’t even imagine what the gyroscopic precession must have been like swinging all that junk (ie crank case) through the air!
Do you like these RADIAL ENGINES ? :)
No, but I like these rotory engines.
These are not radial engines they are rotary engines if he whole thing rotates with the prop.
These are ROTARY engines. Not radials.
Good morning to all from SE Louisiana 22 May 22.
I like rotary too!
It wonders me how so easy was to start them, generally it ocurrs at a first flip of the prop ! But so dangerous to do it !
First clip. I can see that engine stand folding up at some point.
Жаль что у нас нет такого.
So, why is it better to have all that rotating mass, with the difficuties in inlet, exhaust and ignition, plus unbalance and gyroscopic effect rather than a fixed radial engine and rotating crankshaft?
At the low flying speeds of the time having the cylinders rotate greatly improved and equalised the cylinder cooling.
No unbalance, but lots of gyro effect! Cooling was a great advantage as no rad to puncture or weight of onboard liquids and still no more difficult to produce than a radial! Cheers
What about the Clerjet rotary engine, with a carburetor and throttle?!
Where are you from guys ?
I am so tired of people who have no knowledge about engine using the wrong name for a engine type . Those are rotary engines. Mazda never built a single rotary engine.
They are called rotary radials. ROTARY describes the operation while RADIAL describes the layout.
@@shelbyseelbach9568 They were never called "rotary radials" until the 1970's when Mazda highjacked "rotary" as a name for the Wankel engines they were producing. Up until THAT point a rotary engine was simply called rotary.
@@waynepurcell6058 And? They used to just call wooden sailing ships "ships", then they started cladding them in iron and had to call them wooden ships, then they installed boilers and paddle wheels and had to call them wooden sailing ships. Things change, you either change with them or you waste time complaining that things change and you simply get left behind. Your choice.
Radial Rotary engine ,stationary crankshaft orbiting cylinders ! But Mazda rotary engine ,rotating crankshaft rotating orbiting triangular piston ! 🤔
Is that a two-stroke engine don’t sound like a four stroke that’s for sure
I've often wondered about crankshaft failures on those engines. With all of the rotating mass, it seems as if rotating balance would be difficult to achieve. And depending on main bearing type, Babbited plain bearings, or roller bearings, it seems on either, it is an awful unbalanced load to have on them.
Bearing failure notwithstanding, I can see the whole engine pirouetting to Earth, from great heights, when the crankshaft mount loosened, and the whole mess ripped itself from the airframe.
Balance is not a problem with those engines for several reasons. Most surprisingly, the pistons don't actually reciprocate! They follow a purely circular path that is centered on the crank big end journal and of course, offset from the axis of rotation of the cylinders. The connecting rods similarly pivot around the crank big end journal.
@@Circlotron Aw, c'mon! You're wrecking my imagined loose engine sailing through the grey cast, plummeting to Earth, only to bury itself in some lonely, muddy field in Belgium, cows wondering what this thing is! The pilot, still conscious, is able to fly the now glider, to a similar muddy field a few kilometers away from the engine!
Seriously, I get it, but even with the crankshaft, hence pistons, rods, etc., bolted to the airframe, immobile so to speak, we've still got cylinders, heads, and crankcase weight spinning around right?
Huge Johnson Yes, but all perfectly similar weighted components! What you may not have cottoned onto, is the Gyroscopic effect that this mass has! A giant flywheel effect, but able to self air-cool, even at standstill, on the ground that is! Added to the same gyro effect of the prop it took a lot of piloting skills to fly the aircraft they were fitted to! Easy to bank- turn with that effect...very different to turn against it! I had the privilege of totally rebuilding one when I was just 17 in1964! Massive amount of work,( and all to ARB standards), but a privilege to see the brilliant engineering for that period! If anyone has the chance to view anything so connected to these engines, go take a look! Truly terrific to behold! Cheers
@@nigelparker5886 You are fortunate to have been so involved. There is an aerodrome with a bunch of old aeroplanes not too far away from me, and while I've been close by for antique automobile meets, I've strangely enough not gone to see the planes or the meets when they fly!
I guess it's something I should do before I leave Earth! Cheers!
Huge Johnson Thanks, please go and enjoy it all! Take the time to take in detail that the experts can describe! Cheers
Museums are neat but you can’t hear them or see them fly as their meant to do.
Why do you steal other ones vids?
None are radials. Check your facts if you don't know your subject.
