The new concept of power transmission to the entomopter wings

Abstract

AbstractThe aim of this study is to discuss the design of the mechanism used for power transmission to the entomopter wings in order to perform a flapping motion and control the angle of attack of the wings. The study presents a kinematic diagram and a simulation model obtained in SolidWorks for the proposed mechanism, which includes a slotted link mechanism and a slider mechanism (with bilateral slider) that actuates the rocking lever of the wing. The simulation model allowed for observation of the system work and verification of the adopted kinematic assumptions. The comparative analysis showed that trajectories obtained from the both models are very similar. The correct operation of the proposed solution has been demonstrated by building a prototype of the mechanism and conducting experimental research. In the case of the application of the solution presented for the real object it is sufficient to choose the system parameters in order to properly reflect the living organism. The proposed mechanism is characterized by simplicity and offers opportunity for miniaturization while ensuring reliable work at reduced demand for power to drive the mechanism. A technological advantage of the presented solution is the use of only one component in order to perform flapping wing motion and change the angle of attack of the entomopter.
