Wooden Oscillating Air Engine 3300 Rpm

Описание: In this video I will show an air engine that I made, to show the power of the engine I added a propeller to see if it could overcome the resistance of water because air is too thin for a power test.

It's a single acting engine because i wanted to make it as simple as possible but still good looking. Every part on the axle is cross pined and locktited... now parts won't fly all over the place anymore...HA!

I was very surprised when I tested the engine under water, for some reason I didn't think it would work at all when submerged underwater.

3300 rpm is what the engine speed is, based on this calculation
I recorded the top speed engine sound from the video, so I could zoom in at the sound recorded and focus on a 1/10 second and count the sound spikes. 1/10 second equals 11 sound spikes which is then multiplied by 10 to get 1 second, so 1 second equals 110 sound spikes which is then multiplied by 60 to get one minute and that equals to 6600 sound spikes per minute. Then the 6600 sound spikes is divided by 2, because 2 sound spikes equals one revolution of the crankshaft which gives me the definitive answer at 3300 rotation per minute. If this is wrong tell me.

I also compared my engine sound with this electric engine here from "Thomas Ferko" @    • 3,000 RPM  RECIPROCATING MAGNET MOTOR
