Modelling and Simulation of a Paraglider Flight

A simulation model of a paraglider flight is presented in this paper. The dynamics of the paraglider trajectory, as well as its twist angle are governed by a complex interplay between gravity and drag force. Differential equations describing this dynamical behaviour are developed by balancing all the forces and torques acting on the system. The developed model allows to compare different flight situations and find out optimal values of the parameters, which may be used in further steps for example optimization of the towing process. Simulation results of the paraglider launch process using a vehicle unreeling winch and subsequent gliding under different wind conditions are compared with real data.
