N2 - An unmanned aerial vehicle (UAV) released in mid-air experiences a wide range of dynamic pressure. A lift force must be kept below a structural limitation; however, an available resource is often limited. This study reveals the aerodynamic characteristics of the permeable membrane wing that can be used for the UAVs. This study especially focuses on a dynamic-pressure compensation effect by the permeability of the wing. Permeable membrane wing models made by polyester meshes and a metal frame are prepared, and their aerodynamic performances are investigated at Reynolds number of O (104). As a result, a lift coefficient decreased as a dynamic pressure increased in this Reynolds number. The obtained results indicate the possibility of the dynamic-pressure compensation by the permeability of the wing.
