Biofluiddynamic scaling of flapping, spinning and translating fins and wings [PDF]
, 2009 Organisms that swim or fly with fins or wings physically interact with the surrounding water and air. The interactions are governed by the morphology and kinematics of the locomotory system that form boundary conditions to the Navier–Stokes (NS ...

Research and Test of X-wing Flapping-wing Mechanism Based on the Crank Slider Mechanism
Jixie chuandong, 2023 A X-wing flapping-wing mechanism with wings flapping symmetrically is designed. The crank slider mechanism is adopted to convert the circular motion of the crank into the linear reciprocating motion of the straight shaft, and the straight shaft drives ...

Comparison of Power Requirements: Flapping vs. Fixed Wing Vehicles
Aerospace, 2016 The power required by flapping and fixed wing vehicles in level flight is determined and compared. Based on a new modelling approach, the effects of flapping on the induced drag in flapping wing vehicles are mathematically described.

Design and Coupling Dynamics Research of a Single-drive Multi-mode Flapping-wing Aircraft
Jixie chuandong, 2023 Aiming at the problems of single flapping wing movement mode and low flight flexibility and stability of flapping-wing aircraft, a single-drive multi-mode flapping-wing aircraft based on the space linkage mechanism is designed. The kinematic model of the

Effects of deformation and vibration characteristics of wings on flapping flight
Mechanical Engineering Journal, 2015 The dragonfly wing is passively deformed under flapping and has the strength to withstand high flapping frequency simultaneously. These characteristics of deformation and vibration of the wing are important for flapping flight.

Towards Bio-Inspiration, Development, and Manufacturing of a Flapping-Wing Micro Air Vehicle
Drones, 2020 Throughout the last decade, there has been an increased demand for intricate flapping-wing drones with different capabilities than larger drones. The design of flapping-wing drones is focused on endurance and stability, as these are two of the main ...
