The rotary engine is made up of a block and crank shaft like normal engines but how they work is different. Normally the crankshaft spins inside the block, but the rotary engine is actually a block spinning around the crankshaft in a [|rotary motion.] Rotaries are better in airplanes because they are way lighter than other engines and are very smooth running. Rotaries delivered power very smoothly because there are no parts moving back and forth, and the large rotating cylinders acted as a flywheel to improve smoothness even more.
