Aerodynamic characteristics of a flexible membrane wing

Oscillatory motions of a prestrained compliant membrane caused by fluid–membrane interaction

“…They reported the membrane profile and the lift, tension, and moment coefficients. Greenhalgh and Curtiss Jr. (1986) performed experiments to study the aerodynamics of flexible membrane wings of triangular, parabolic, and elliptic shapes. The test wings were made of thin sheet metals that were flexible to some extent, but not so flexible to be fully compliant to the airflow.…”
