Hi Ian, Excellent job of explaining this engine. Years ago my father and I would always stop by at Wright Patterson AFB in Dayton. This is where i saw my first cut away view of a real radial engine on display. I remember distinctly as the light bulb went off in my head about the single giant conrod and all the others that attached to it via a wrist pin. I never had time to figure out the valve cam timing but you have done an excellent job of showing that concept. My background is retired tooling and die engineering. I have a great spacial orientation thing for design and this is one video that has burned into my brain. Great Great job! If you ever get to WPAFB the cutaway engine is still on display!

@NotTheCIA19617 жыл бұрын
Block engines were (typically) FAR lighter weight leading to less weight in total, but also typically didn't put out as many horses. They also were far more vulnerable than radial engines due to them requiring a liquid cooling system whereas the radial engine is air cooled. Simple explanation.

Like how they are not naturally balanced because of the odd number of cylinders, though I get the firing order and the logic behind it I don't see how it's balanced, at least not like the boxer engine where the Pistons are horizontally opposed.
@immikeurnot6 жыл бұрын
Advantages of a radial - easier to design and maintain a cooling system, lighter, one design can be stacked to create bigger engines, easy parts replacement (hang new jugs vs sleeve a block)... Disadvantage - generally much larger diameter than an inline which means more drag, less overall power potential since cylinder head temperature is dependent on air cooling "Like how they are not naturally balanced because of the odd number of cylinders" Odd number of cylinders is actually to make it balanced. Note that in the video, it skips firing one cylinder every time. If you had an even number of cylinders, you'd have to have two cylinders fire sequentially at some point. A fair example of that effect is how Harleys are shaky pieces of shit - their engines use the same common journal setup as a radial, but with only two cylinders, and the angle between the two cylinders doesn't help matters. Bad design... "Radial engines also rely on OIL COOLING and have plumbing and a radial for that also !!!" Wrong. Lower-powered radials didn't need an oil cooler setup. It was the turbo and supercharged radials running very high outputs in WWII that had to be oil cooled. The water-cooled engines of the same era also usually had an oil cooler, too. NACA cowls and the Germans installing fans in the cowling helped reduce the size of heat exchangers needed. Radials were known to be harder to damage. Even with an oil cooler, their cylinders and cylinder heads were still air-cooled, which reduced the amount of surface area they needed for the cooling system. In an inline, the cylinders are surrounded by the case or block and the head(s) were a solid piece, neither allow for any real air cooling. In the end, the oil cooler and associated plumbing was much smaller than the radiator of a water-cooled plane.
