Via the mixture assy and carburetor at the end of the hollow crankshaft. The mixture next gets drawn into the crankcase and next through the (9) induction pipes, connected to the inlet manifold on the cylinder head (containing the inlet valve) into the respective cylinder. Thanks for watching !!

Thanks for giving me a better understanding of how it works. I just watched a video of a Nieuport 28 and was wondering why it didn't sound like it was running on all cylinders. Was it a way of controlling the engine speed . I do remember at an airshow in New Zealand the Bleriot would cut the ignition to slow the plane and hopefully it would start back up . Thanks for a great video.

No, it is a rotary engine, meaning that the propeller is bolted to the crank case and the whole engine rotates around the stationary crank shaft. It is shown at the end of the video. You may also want to watch the real engine run at kzbin.info/www/bejne/a4qZgaZ6m8p5gJY Thanks for watching !!

Wow! This was really informative. Thank you for making this. It’s neat to see how things have evolved in piston driven engines. Despite their complexity and danger level what were their drawbacks? Any known issues? Also was balancing a huge factor?

@pierrejansen2702 4 ай бұрын

Thank you for your compliments. The major drawback was the need for more power. Adding additional cylinders (second row) was attempted. To keep the centrifugal forces acceptable the RPM of the engine was quite low (1200-1500 RPM) Thanks for watching !!

For a while this operation was stuck in my head since I couldn't comprehend how such precise synchronization could have been achieved without with almost-contemporary advances in engineering mathematics and firearm technology then I realized: The trigger is not automatic. The trigger is ENGAGED and then can be fired at will (maintaining synchronization) until it is disengaged. What a very neat piece of engineering, but I am sure it would've frustrated the pilots that the machine gun fire was not as immediate as a move of the finger. Even then the real beauty is in creating cam gear that could 'sense' the rotation of the propellor/crankshaft at such high rotational speeds in era where useful infrared detection was a piece of sci-fi! Why hasn't anyone written a book on the mathematics that went into older technologies??

@pierrejansen2702 4 ай бұрын

Indeed, the firing triggering (engagements) happens when the rollers go over the cam which is mounted onto the engines main gear. There is some documentation but it's definitely something someone could have written a book about. Thanks for watching !!

How to intake air from the outside engine still confused

@pierrejansen2702 4 ай бұрын

The Gnome induction cycle - the petrol line is connected to the hollow (stationary) crank shaft (doesn't rotate. Through a petrol tube within the crank shaft, the petrol gets drawn into the crank case via the petrol nozzle on the front end of this tube. When a piston reaches its bottom position (BDC - inlet stroke), the petrol gets drawn into the appropriate cylinder though the 32 holes (ports) at the skirt of the cylinders. The petrol within the cylinders will mix with the air that was drawn into the cylinder during the inlet stroke, because the valve is open. (see 8:47 etc. video frames) Note that this valve handles both the inlet- and exhaust flows (single valve = monosoupape in French). Hope this helps and thanks for watching !!

Qual RPM desse motor ?

@NorthernChev 5 ай бұрын

Except for that part where the excessive rotational mass made it extremely difficult to turn the plane in the same direction as rotation... Essentially you could only effectively turn the plane one direction with any ease.

@pierrejansen2702 5 ай бұрын

The often-repeated tales about tricky aircraft handling due to the gyroscopic effects of rotating engines are exaggerated. The rotational mass rotates at approx. 1250 RPM max. Several of my contacts (pilots) flying rotary engine powered WW1 (replica) planes, indicated that they hadn’t noticed any excessive gyroscopic effects. An experienced pilot automatically compensates for those things. Turns to the right might be a little quicker, but that is because the rotary engine tends to pull the nose down [in that direction], and you make a quicker descending turn than you make a climbing turn.

The cylinders were not installed on the case first. It's too hard to install pistons wirh rods attsched from inside the case. The master and link rods were first assembled. Then the crankshaft and crankcase were assembled around the master and link rod assembly, with the rods protruding from the cylinders. The pistons with rings installed were attached to the rods, THEN the cylinders were installed over the pistons and secured to the case.
