A paraglider longitudinal flight mechanics modeling

In this paper, it is developed a descriptive theory of paraglider flight mechanics, a gliding aircraft designed for entertainment purposes. After the analytical representation of the equipment geometry, the equations of longitudinal motion are derived and the most relevant parameters of performance and stability are identified. The developed theory is tried out based on real gliders analysis showing consistent results. The theoretical results here presented about paraglider flight mechanics can not be found in the available bibliography. It's expected that a scientific approaching of the paraglider stability and performance, as a branch in the aeronautic engineering field enables relevant improvements on flying and safety characteristics of these unconventional aircrafts.
