1、The gulls flew off, wings flapping.
2、The movement or sound of repeated flapping.
3、There are beasts flapping their wings.
4、The paper also computes the flapping power and flapping efficiency of the flexible flapping-wing, and their changes with flapping angel, velocity, and so on.
5、A host or service is determined to have stopped flapping when its percent state goes below a low flapping threshold (assuming that is was previously flapping).
6、Numerical study of aerodynamics for flexible membrane flapping-wing MAV
7、He tried to tuck his flapping shirt inside his trousers.
8、Do atop flapping 'll get the job done in time.
9、 The sails were flapping gently in the wind.
10、The flag was flapping about in the light wind.
11、The flapping wing with a wing flexure consumes less energy than that without a wing flexure in a flapping cycle.
12、When flapping-wing flight at small attack Angle, wing had wing-blade improve effectively aerodynamic characteristic of flapping-wing.
13、A 2-DOF piezo-actuated flapping mechanism was designed according to the theory of flapping-wing flying rhythmic movement of insects.
14、A host or service is determined to have started flapping when its percent state change first exceeds a high flapping threshold.
15、The results are helpful to the design, fabrication and application of the micro flapping actuator.
16、Therefore it is very important to consider adopting a wing flexure in flapping wing design.
17、As feathers became larger over time, flapping flight evolved and birds finally became fully air-borne.
18、The result of wind tunnel test provides guideline in aircraft design of flapping-wing MAV.
19、The bathers reappeared on the grass - ridge racing and flapping wet towels.
20、the feathering angle of the rotor blades with linear torsion, including the action of the swash plate and flapping adjustment;
21、 There was a flutter of wings, and butterflies spread their beautiful scaly wings, flapping the air to chase each other.
22、Stated another way, the "butterfly Effect" does not propose that a butterfly flapping its wings causes the change, merely that the flapping results in an imperceptible change in local conditions.
23、Scobie watched the bearers go slowly up the hill; their bare feet very gently flapping the ground.
24、The computation and experiment results indicate that the wing flexure can increase the average lift of the flapping wing.
25、The test results indicate that the uncertainty of flapping parameters meets the calibration requirements of standard rotor blades.
26、The flapping-wing flight mechanism of animal is investigated in particular, and the results provide a theory foundation for developing BFAR.
27、"Angry Birds" is flapping from touch screens to big screens, books and toys. Will one of the best-known mobile apps become an entertainment franchise?
28、While some distance away, I noticed the pages of a book on her knees flapping this way and that in the wind.
29、Already they could see the fur caps of the soldiers, could distinguish officers from privates, could see their flag flapping against its staff.
30、It would be wrong for us to start flapping about now and say that we didn't know what we were doing.
31、I am standing with a flapping rubber mat on a broom handle trying to contain the edges of the wall of fire as it marches across the buff-colored field.
32、It is clear that each one is crossing the river, and each one is flapping its wings. It is clear that each one is acting differently, but when you look carefully, there is no difference.
33、When the speed of AUV is zero or low speed, lift is produced by the vibration of fin stabilizer at the horizontal position, which is similar to the flapping wing flight of insects and birds.
34、By contrasting the computed aerodynamic force of flexible flapping-wing and rigid wing, it is found that if the flexibility is controlled suitable, it can enlarge the lift and thrust effectively.
35、Now set her down on a table or other flat place. Her wing will suddenly stop flapping. Turn the switch off when you are not playing with your fairy.
36、It is concluded that all of the tested bionic wings can generate lift force, however the flexible wing has best kinetic and aerodynamic performance among them, as well as flapping frequency and amplitude are the main factor of effecting on lift force generation.
