Abstract [en]

This project outlines a cost-effective numerical simulation method for the analysis of the longitudinal mechanics of paraglider systems. It is built on static stability methods for the analyses of low subsonic aircraft, non-linear lifting line methods for aerodynamic parameterization, and frequency domain analysis methods derived from system theory. Paragliders possess a glide polar in the range of ≈ 25-60 km.h−1 and display underdamped dynamic responses dominated by a long-period mode. The simulation results for performance and dynamic response are qualitatively valid relative to experimental data and in the same order of magnitude.

Abstract [sv]

Projektet handlar om utveckling och utvärdering av en kostnadseffektiv simuleringsmodell för longitudinella frihetsgrader av skärmflyg. Modellen är byggd med fundamentala metoder för stabilitetsanalys av låghastighetsflygplan, ickelinjära liftingline metoden för aerodynamikanalys samt frekvensanalys från systemteori. Ett skärmflygs glidepolar är definierad på hastighetsintervallet ≈ 25-60 km.h−1 och visar ett underdämpat dynamiskt svar med lång period. Simuleringsresultaten för prestanda och dynamisk stabilitet ¨ar kvalitativt giltiga i förhållande till experimentella data och visar samma magnitud.
