The morphology and kinematics of a flying animal determines the resulting aerodynamic lift through the regulation of the speed of the air moving across the wing, the wing area and the lift coefficient. We studied the detailed three-dimensional wingbeat kinematics of the bat, Leptonycteris yerbabuenae, flying in a wind tunnel over a range of flight speeds (0-7 m/s), to determine how factors affe...

This paper relates the camber control of a morphing flap actuated by macro-actuator composed five electromechanical actuators. Controlling could provide fuel consumption reaching specific aerodynamic profiles. Due to their reliability, actuators are used for macro-actuator. They located and integrated resist realistic forces. Their is determinant ensure mission. Based on simplified model using ...

An investigation has been made into the application of the theory of thin sections to the design of hydrofoils having high cavitation speeds. Consideration is given to both symmetrical sections, which themselves are suitable for struts, and camber-lines, which, when used with the symmetrical sections, lead to cambered sections which are suitable for lifting surfaces. In all the aim has been to ...
