Aeroelastic Response of Aircraft Wings to External Store Separation Using Flexible Multibody Dynamics

open access: yesMachines, 2021
In aviation, using external stores under the wings is a common method of carrying payload or fuel. In some cases, the payload can be rigidly attached to the wing.

Research on the Nonlinear Structural Dynamic Characteristics of the Rigid Flexible Coupling Folding Wing Model for Aircraft

open access: yesEngineered Science
During the working process of the folding wing, there is not only a large-range rigid body motion but also a deformation motion of the flexible components. The problem of the rigid-flexible coupling of the structure is extremely complex.

Piezoelectric energy harvesting from flexible delta wings

open access: yesTheoretical and Applied Mechanics Letters, 2018
: The potential for harvesting energy from a flexible delta wing using a piezoelectric bimorph is experimentally investigated. Different configurations of the proposed harvesting system were tested in a wind tunnel over a broad range of airspeeds.

Development of a flapping mechanism inspired by the flexible wing-base structure of insects for wing motion control

open access: yesJournal of Biomechanical Science and Engineering, 2022
Flying insects are capable of hovering and rapid maneuver under unpredictable environments. The principal wing-beat is generated by transmitting the rhythmical contractions of power muscles to the exoskeleton and wing-base articulation.

3D Flapping Trajectory of a Micro-Air-Vehicle and its Application to Unsteady Flow Simulation

open access: yesInternational Journal of Advanced Robotic Systems, 2013
A three-dimensional (3D) trajectory detection framework using two high-speed cameras for the flapping flexible wing of a micro-air-vehicle (MAV) is presented. This MAV, which is called the “Golden Snitch”, has a successful flight record of 8 minutes.
