  • quick question, how does the fuel get pumped into the chamber with the engine spinning like that?

  • @ommie299 The crown of the piston has an atmospheric valve that allows the fuel/air mixture to come through from the crankcase. The crankcase is supplied from the tube in its center via the carburetor on the aft end. See kozaero.com for more details.

  • Can I use this sound in Japanese Aircraft Museum?

  • @ymgjpn

    Yes, you can use the sound or entire video if you like. There is a good version on my web site

    Gnome is the original rotary engine

  • @lmo1131

    The crankcase does NOT rotate. It's fixed to the same position, hence the cylinders rotate around that axle.

    In a radial the cylinders stay in the same position and the crankshaft rotates. In the radial the exact opposite applies. Look it up on Google, there are some nice explanations.

  • You should team up with someone to build a replica airplane of the period and make that thing fly. That would be a star attraction at an airshow!

  • @MrBurningPride

    The Gnome is a the real rotary, i think the rotary you mean is the Wankel with rotative piston (or rotor) engine...

  • How much cooler would it be to have this hunk of metal flying around the engine bay of a car than a Wankel rotary?

  • @McLarenMercedes

    Correction, I meant the crankshaft doesn't rotate.
