    A point about the rotaries is that the pistons only reciprocated relative to the cylinders, not to the aircraft, as they orbited around the fixed crankpin. This should have made the engine run very smoothly with little vibration; a good characteristic for a wood and fabric aircraft. There was no way to attach an exhaust system however, so the gasses together with the castor oil from the total loss lubrication exited directly from the top of the cyl heads. It was said that the pilots had lovely complexions and very regular bowel movements.

      That was part of the reason but in a war pilots are expected to just tolerate that.
      The real reason they went out of fashion was because it was very hard to cool them efficiently above a certain size. Also as pistons got heavier they put more strain on the crankshaft and broken crankshafts became a common failure in the later part of WW1.
      The reason rotaries became commonly used was because they generated their own airflow to cool themselves so didn't need radiators. That matters when you have very low powered engines where every kg matters.

      Another problem with the rotary engine is the gyroscopic force that it produces, that causes the aircraft to climb if you turn one way and to dive if you turn the other way (and also to turn one way or the other if you intend to climb or dive). Pilots in training had to learn about these effects. When the engine sizes reached about 200hp, the gyroscopic forces became unacceptable and the rotary engine had to be abandoned.

      many did not understand the difference between a gnome type rotary and a common radial, both have french origins, th e rotary was think to reduce weight and improve cooling, but with the improving from the classic piston engine inline and radials, the rotary was fast obsolete, because high consumption (oil and gas) and heawy gyroscopic effects (who increase with the power), after 1917 had the classic engine same weight to power ratio or better as the rotaries, so for example, the Renault V12 12F liquide cooled engine from the 1917 Breguet XIV deliver 280hp and was far better and more reliable...The Renault 12cyl was fast improved and the power rise up to 454hp in 1918, was the first aircraft engine fitted for tests between 1918 and 1920 with a "Rateau" turbocharger to improve climb performances, but this was unreliable and not serial built, it was still too early for the turbocharger, who came back in WW2 on the Allison V1710 from the P38...

    What is always left out of these explanations of radial engines is the cam ring. Understanding the cam ring geometry shows the reason why there is an odd number of cylinders in each engine row. Hint a three cylinder will run with a single lobe ring (one lobe on the intake and exhaust ring) turning opposite to engine rotation at half speed. It will also run with a two lobe ring turning the same as engine rotation at quarter speed. Say the intake lobe is starting to open #1 intake valve. Rotate the engine 240 degrees the #3 piston is now in about the same position to open the intake valve as #1 was. The cam lobe has rotated 120 degrees and is there to open #3 intake valve. Do not feel bad if it does not click right away Took a couple of hours with a compass and protractor for me to see the light. I passed the A&P written in 1970 and that question was not on the test.

    A Wankel should be called a rotor engine, not a rotary engine. Rotor engine. Piston engine.
    All rotary piston engines are a type of radial engine. All rotaries are radials, but not all radials are rotaries. In fact, the radial cylinder arrangement was first developed as a rotating engine to be built into the wheels of early motorcycles, with the fixed crankshaft acting as the axle. The first fixed radials were developed by converting rotary engines to be stationary and their cranks turning. The Manly-Balzer engine used in the Langley Aerodrome is a good example of this.

    The factory-produced Cessna Cardinal never used a Wankel engine. It used either an O-360 (on the fixed gear version) or an IO-360 (for the retractable gear version) Lycoming engine. Both are flat (opposed) 4-cylinder engines. It's possible someone put a Wankel onto a Cardinal as a one-off experiment, but it was never sold with one.

    • @quinnobi42
      @quinnobi42 2 роки тому

      The rotor is mounted on an eccentric shaft, which is basically a round shaft that connects to another shaft off-center, so when the crankshaft rotates, the off-center part of the shaft moves around it. It's a bit hard to explain in words. If you google 'eccentric shaft' you'll get some images that should explain this better than me. The rotor fits onto the eccentric part of this shaft, so when the shaft rotates, it moves the rotor side to side in the housing. This works in tandem with the gear on the back of the rotor which meshes with the smaller gear that is fixed to the housing, so that the rotor moves as we want it to. The end result is actually a 1:3 ratio between the crankshaft and the rotor, so the rotor completes 3 full revolutions for every one of the crankshaft. You can sort of see how this works with little model wankel engines. Here's a video that shows the disassembly of one that has a good bit where he turns the eccentric shaft by hand and you can see how the rotor moves ua-cam.com/video/FwGLnXw6_vQ/v-deo.html

    The Wankel engine declares as displacement the volume of a single chamber out of the three delimited by the rotor.
    This may suggest a high specific power, but this is false.
    Its thermodynamic efficiency is also very poor as evidenced by the heat of its exhaust
    and its consumption.
    One face of the rotor returns to its initial position in the cycle with each revolution. So it's a 2-stroke engine.
    (2 turns for a 4 stroke).
    The 4 phases are present in all heat engines.
    This engine is in all respects comparable to a 3-cylinder 2-stroke, to which a multiplier by 3 would have been added at the crankshaft outlet.
    Which wouldn't have changed either its displacement or its combustion cycle, right?
    As for reliability, it is dismal with a complete overhaul of the 3.9L engine of the Mazda RX8 every 80,000km
    to compare with the indestructible Honda s2000 2L.

    The radial engine was no doubt way ahead of their time but not very aerodynamic. The 12 cylinder R 12:22 olls-Royce Merlin was by far the best engine of WWII. Not only for fighter aircraft, but bombers too. The best for dependable horse power, torque and fuel consumption. The P-51 Mustang would not have been the greatest piston powered fighter without the Merlin. Could not see the Mustang with any other engine and flying escort for Bomber Command over Berlin. Even Reich Marshall Goring said he knew the war was lost when he saw fighters over Berlin escorting the bombers. The Avero Lancaster (designed and built in Canada 🇨🇦) was powered by the Merlin. Which was only the GOAT because of the Merlin. God bless us all

Spark comes from a ring mounted to the crankshaft with corresponding points of contact on the spinning crankcase.

Spark is provided by a ring with a contact point. They are 4 stroke but share a lot of attributes with a two stroke. Some of them didn't have a typical throttle. You governed engine speed by magneto select usually selecting between 3,6,or all 9 cylinders firing. There was also a "blip" switch on the flight stick that you could cut the spark off and on with for extra rpm refinement.

    The Wankel engine has one fault. Fuel consumption/power output. A wankel engine with a nominal 2 litre displacement has a fuel consumption closer to a 3 litre for the power of a 1.6-1.8

    The Wankel/Mazda is a "rotary" engine. It uses a rotor instead of pistons. The radial and what you call a "rotary" engine are both a piston engine. Both are actually a radial engine, in fact. The thing you call a "rotary" engine is an early radial engine, used in some pre-World War 1 aircraft and World War 1 aircraft.
    It fell out of favor post WW1 because it hampered the maneuverability of the aircraft, acting like a very efficient gyroscope, thanks to the heavy crank case, cylinders and heads rotating at high speed. The "crankshaft", rods and pistons were stationary.
    Later rotary engines had a rotating crankshaft and reciprocating rods and pistons, eliminating the gyroscopic effect of the engine.
    The Mazda Wankel rotary engine being a "gas guzzler" is an understatement. They were also difficult to tune and keep running properly. The three seals on the rotor tips also wore out quickly..
    All three of these engines are obsolete. With the possible exception of the Mazda/Wankel none are used in cars (Does Mazda still make an RX rotary powered car?) or new aircraft.
    Around 2005-2007 I saw someone had a startup or "Go Fund Me" attempting to pass off a scaled down old pre-World War 1 tech "rotary" radial engine as "new tech" to power a line of garden tractors. As far as I know, that company went bust ... no advantage over a Brigs & Stratton piston engine, and a boatload of disadvantages.
    None of these three engines are very fuel efficient, to be honest. Why do you think the base line Cessna high wing and other small private piston engine aircraft (including crop dusters) DON'T use a 2; 4; or 6 cylinder "boxer" engine, and not a radial engine?
    I don't know what the point of this comparison is. With the possible exception of the Mazda Wankel rotary engine, all three are out of commercial production. The "rotary" radial engine since the early/mid 1920's. The rotary since the 1960's. Emission Control laws likely killed off the Mazda Wankel rotary somewhere along the line.

      The rotary aircraft engine IS a rotary engine. What does rotary mean? It means to rotate, to spin. The entire engine spins around the crankshaft of a rotary. Rotary engine=spinning engine. They were even patented under the name "rotary engine".
      Mazda just called the Wankel a "rotary" because license on the Wankel name expired and Mazda didn't want to pay royalties. Rotary is just a name they basically drew out of a hat. The definitive answer is to ask yourself which ENGINE itself spins.

    G'day,
    Actually, the FIRST Rotary Engine was designed and built by Lawrance Hargraves, at Stanwell Park, NSW, Australia, in the 1880s ; it was a 3-cylinder unit, running on Compressed-Air...(!), with the Cylinders mounted at the Hub of a 3-bladed Propeller, each Cylinder attached to a Blade's Leading-Edge Spar...
    Hargraves was comparing Propellers with Ornithopters, propelling large Models, before he began experimenting with Kites ; and comparing the Lift-generating ability of Flat-Plane Surfaces versus that of Curved Aerofoils...
    Sadly, Hargraves' Propeller was so very badly designed that it was horribly inefficient, and thus he led himself to wrongly conclude that Flapping Wings were slightly more efficient than Propellers, as a means of Aerial propulsion..
    But, yeah, to see photos of his work..., please feel free to backtrack me to my "Personal Aeroplanology..." Playlist, thererein to find and check out,
    "The Aeronautical Works of Lawrance Hargraves..."
    A pair of Videos, made by reading a Booklet of the same title, by the Sydney Technological Museum, to camera ; it was published in about 1932..., I acquired it in 1970 - so it's probably a bit of a rarity...
    Also, currently, it appears that Wankel Rotary Engines, running on Compressed-Air..., are proving to be highly successful in Ukraine, powering Drones and Unmanned Aerial Vehicles...; Small, Light, Powerful, Smooth, with No Infrared Signature....(!).
    So Felix the Nazi Wanker's Fuel-farting Fire-Breathing Tri-Lobed Vane-Pump running backwards...; has finally turned out to have a (literal) Killer-Application, at which it outperforms all rival competing technologies.
    A bit of a pity that all it's good for is powering Kamikaze Suicide-Drones...; but what else does one expect : from Nazi Science applied to Engine Technology ?
    Such is life,
    Have a good one...
    Stay safe.
    ;-p
    Ciao !
