Composite images of the flapping wings at the end of up- and down-strokes. ( a ) The clap-and-fling effect is strong with wing distance of 16 mm (0.64 cm ); ( b ) The clap-and-fling effect is almost diminished with wing distance of 40 mm (1.6 cm ) Reprinted from Ref. [ 42 ].
Meanings on flapping-side motion. ( a beneficial ) Feather axis, flapping axis, and you can flapping angle ? ; ( b ) New parabolic bend acting camber regarding a wing part. Reprinted out-of Ref. [ 49 ].
The newest non-dimensional forces to your side distance out of sixteen mm in the hanging computed in the current interlock and you may regarding the ideal interlock utilized in the previous performs. Reprinted out-of Ref. [ 42 ].
Circulate fields into the 75%R-airplanes while in the off-coronary attack clap getting J = step 1. Due to inertia push resulted from the side mass, the newest wing camber changes out of curve-upwards ( a beneficial , b ) to contour-off ( c , d ). The new white shape is the intersections between your wings as well as the jet, symbolizing wing parts. A respected edges try designated having light circles.
Disperse fields inside the 75%R-airplanes throughout the right up-stroke fling to own J = step one. The lower stress part ap-pears first of all around the leading sides ( good – c ), following slowly increases toward whole area involving the wings ( d – h ). A leading sides try noted with white circles.
Move fields inside 75%R-plane throughout upwards-coronary attack fling to have J = 1. The reduced pressure part ap-pears first and foremost around the leading sides ( good – c ), after that gradually increases with the entire place within wings ( d – h ). A prominent corners is actually noted having light circles.
