Machine and vehicle examples

These examples are machines and vehicles, from a toy plane and a model rocket to gears, engines and a compressor. Each starts from 2D sketches. The plane, the rocket and the rear wing become solids with OpenCASCADE, the spur gears are meshed by netgen and loaded in NGSolve, and the excavator arm moves as one constraint sketch. The Wankel engine and the scroll compressor run through their cycle, with the areas of their chambers and gas pockets measured along the way.
