Inflight Measurements in Circling Flight and Validation Calculations

Abstract

Data from flight measurements will be used, to validate prediction tools for future sailplane designs, especially calculations of the rudder de- flections under fully trimmed circling conditions. 3D scan data for the geometry of the Discus-2c DLR [5] was used for first validation calculations with the multiple vortex-line method LiftingLine V3.1, which is capable of calculating circling conditions.
