Investigation of Flight Dynamic of Hang-glider

Abstract

This paper shows, how the most important parameters of a two-body system like a hang-glider, can be identified. The first step is to develop a simulation program with an acceptable reality model. Such a model involves a lot of constants. I carried out an investigation of sensitivity ir; order to select the constants that are the most important to specify. The results show that the aerodynamic constant c_mq has the most significant effect on a  phygoidal oscillation. I have developed an identification program and a measuring system to determine the real value of this constant as well as the hang-glider's other aerodynamical and stability parameters.
