Effect of Chordwise Struts and Misaligned Flow on the Aerodynamic Performance of a Leading-Edge Inflatable Wing

Leading-edge inflatable (LEI) kites use a pressurized tubular frame to structurally support single skin membrane canopy. The presence of the tubes on pressure side wing leads characteristic flow phenomena for this type kite. In paper, we present steady-state Reynolds-Averaged Navier-Stokes (RANS) simulations LEI airborne wind energy applications. Expanding previous work where only leading-edge tube was considered, eight additional strut that canopy are now included. shape is considered be constant. influence aerodynamic performance and local field assessed, considering configurations with without side-slip. show decreases increasing side-slip component inflow. On other hand, chordwise struts have little integral lift drag wing, irrespective component. overall characteristics in good agreement studies. particular, it confirmed at low Reynolds number Re=105, laminar separation bubble exists suction hypothetical rigid perfectly smooth surface. destruction angles attack impacts negatively performance.
