Chapter 4: 2015 Problem 6: Magnus Glider

We solve the problem of Magnus glider by experimental and theoretical investigations. In experiment, initial conditions are controlled systematically. The gliders motion can be classified into flying stage and terminal stage. The flying stage has three kinds of typical trajectories depending on initial conditions. The equation of motion for the glider has been derived and solved. All kinds of trajectories found in both stages can be given and compared to experimental conditions. By numerical calculation, we also obtain a phase diagram dividing the conditions for three kinds of typical trajectories. Finally we analyze its stability during the flight.
