In the present study, the effect of elliptical motion trajectory on the aerodynamic characteristics and propulsive performance of a flapping airfoil is evaluated. A periodic horizontal motion (forward/backward) is combined ...

An experimental setup is prepared in order to evaluate the effects of wing flexibility on lift, thrust and power loading of the flapping wings with bending deflection angle (B.D.A.). Hence, two wings with different ...

Hydroxyapatite/poly(vinyl alcohol) (HAp/PVA) nanocomposite samples were prepared by two

different methods of direct mixing and anin situ biomimetic HAp crystallisation in the presence of

polymer. Polymer weight fraction was the variant...
