AERODYNAMIC PARAMETER ESTIMATION OF THE CG CONTROLLED AIRPLANES

Abstract

The aim of this work is investigation of the air forces and their moments acting on the hang gliders. The hang gliders have elastic and flexible structure so the distribution of the air forces is characterised by the shape of the sail surface and the sail surface is either determined by the air force distribution. This research work is built. on the theoretical calculations and practical measurings. The results of this investigation can be applied principally to flight mechanical calculations of the hang gliders.
