Abstract

U okviru ovog rada analiziran je mehanizam mahokrilne letjelice inspirirane oblikom i funkcijom krila vilinskog konjica. Fokus je stavljen na stvaranje kinematičkog uzorka gibanja gore-dolje te gibanja u obliku osmice, s ciljem postizanja traženih aerodinamičkih performansi. Aerodinamički fenomeni aproksimirani su pomoću kvazistacionarnog aerodinamičkog modela, a njegovom primjenom u programskom paketu MATLAB izračunata je sila uzgona i dobivena procjena raspona krila. U programskom paketu MSC Adams simulirana je dinamika sustava više tijela nakon čega su analizirani pomaci, brzine i ubrzanja krila kako bi se osiguralo pravilno funkcioniranje u simuliranim uvjetima, te je ispitana snaga aktuatora potrebna za pokretanje krila prema zadanim parametrima. Također je napravljen i CAD model kao mogućnost za korištenje u svrhe aditivne tehnologije.

Abstract (english)

In the framework of this thesis, the flapping-wing mechanism inspired by the shape and function of a dragonfly was analyzed. The focus is on creating a kinematic movement pattern of up-and-down and movement in the figure of eight, with the aim of achieving the required aerodynamic performance. Aerodynamic phenomena are approximated using a quasi-stationary aerodynamic model, and by using it in the MATLAB software package, the lift was calculated and the wingspan was defined. In the MSC Adams software package the dynamics of the multi-body system was simulated, after which the displacements, speeds and accelerations of the wings were analyzed to ensure proper functioning in the simulated conditions, and the power of the actuators required to move the wings according to the given parameters was tested. A CAD model was also created as a possibility for use in additive technology purposes.
