Abstract

This works presents the fundaments, methods and calculations for the conceptual design of a Fixed-tricycle landing gear for a Minia­ ture Unmanned Air Vehicle (MUAV), a long with its aerodynamic analysis in order to know the impact over the aircraft general aerody­ namics. lnitially using qualitative, quantitative and comparative methods, a determination of the initial parameters of position about the air­ craft fuselage has been performed, using aircraft data previously determined and satisfying clearance distances and angles require­ ments. '· Secondly, structural calculation has been made in orderto define the landing gear struts geometry, using an energy absorption method and making an analogy with a cantilever beam, followed by a structural analysis using the Finite Element Method tool Ansys­ Workbench©. Later, an aerodynamic analysis of the proposed landing gear has been performed, getting its aerodynamic drag using analytical ap­ proaching methods and comparing the results with a fluid analysis carried out by using the Computational Fluid Dynamics tool Ansys­ CFX©, obtaining the drag polar, a new aerodynamic efficiency, and observing a maximum velocity reduction at 8.000 and 10.000 RPM. Ali this analysis were made taking in consideration a cruise altitude and velocity. Finally, a final landing gear conceptual design is obtained, along with its aerodynamic analysis and the impact over the aircraft aero­ dynamics.
