The oscillating air engine is an air-powered engine that I built in the fall semester of my freshman year at George Fox University. I designed it with the intent for speed, as shown by some of my design choices: a large flywheel, offset pistons, and a 45 degree piston/cylinder angle.
I learned all about the exact creativity of machining, and the process of making many design choices that all affect how your product will come out in the end. I encountered some challenges with the machining side of my design, but with the help of an advisor I was easily able to fix it and get my engine running really well.
In the end, participating in George Fox's wobble off, the competition where all the engines are tested according to the category they were designed for, my engine beat the school speed record by 500RPM and won second place in the speed category.
