Abstract

U ovom radu provedena je analiza koncepta piko drona s tri para mahokrila. Kao polazište za analizu uzeta je postojeća letjelica Crazyflie 2.1 na kojoj su bazirane dimenzija i masa piko drona. U programskom paketu Solidworks modeliran je trodimenzionalni model letjelice. Aerodinamički fenomeni su aproksimirani kvazistacionarnim aerodinamičkim modelom, čijom su primjenom u programskom paketu Matlab dobivene uzgonske sile na temelju mahanja krilima ostavljajući trag osmice. U programskom paketu za simulaciju dinamike sustava više tijela (engl. Multibody Dynamics) MSC ADAMS definirane su funkcije sila na tri lokacije motora te je simulirano polijetanje, lebdenje i napredujući let. Također, u ADAMS-u su propisane funkcije gibanja krila te je proveden izračun potrebnih snaga aktuatora pri različitim frekvencijama mahanja. Uz navedeno, u radu su analizirani mehanizmi mahokrilnih letjelica za oblik osmice, njihov način rada i pogona.

Abstract (english)

In this thesis an analysis of flapping wing three axis pico drone was implemented. The starting point for this analysis was the pre-existing aircraft Crazyflie 2.1. from which the dimensions and the mass of the drone was derived. A 3D model of the drone was designed in Solidworks software package. The aerodynamic phenomena on which flapping wing motion produces lift was approximated by the quasi-stationary aerodynamic model. This aerodynamic model was then utilized in Matlab script from which the lift forces were derived. In Multibody Dynamics software MSC ADAMS force functions were defined at three motor locations and takeoff, hovering, and advancing flight were simulated. Also, in ADAMS, flapping wing motions were prescribed and the calculation of the necessary power of actuators for different flapping frequencies were calculated. In addition, mechanisms of flapping-wing aircrafts for the figure-eight shape, their mode of operation, and drive were analyzed.
