Rimša, Vytautas | Recenzentas / Rewiewer |
Baigiamajame magistro darbe pateikiamas orlaivio skrydžio charakteristikų bei autonominio valdymo tyrimas realioje bei skaitmeninėje aplinkose. Analizei naudojamas skaitinis, praktinis tyrimo metodai bei simuliacija. Skaitinei analizei naudojama programinė įranga XFLR5, rezultatų validavimas atliekamas programine įranga Simulink bei skrydžių simuliatoriumi X-Plane 11. Simulink aplinkoje sukurtas 6 laisvės laipsnių orlaivio modelis su rezultatais, atlikus orlaivio aerodinaminę analizę XFLR5 programa. Sukūrus tiriamąjį modelį, buvo atlikta orlaivio skrydžio trajektorijos analizė, gauti rezultatai palyginti su kompiuterio simuliacijoje gautais duomenimis. Darbe lyginami orlaivio judėjimo trajektorijos, greičio, aukščio duomenys, taip pat atakos kampo bei valdymo algoritmo siunčiami signalai vairams. Tyrimas atliekamas bepiločiu orlaiviu „Volantex Ranger 2000”.
In this master thesis, aircraft's handling and control characteristics are investigated. A brief overview of the aircraft's components and design is given and the methods of simulating the flight of this aircraft is investigated in greater detail. Recent papers on similar research topics are analyzed. Both simulation and empirical methods of analysis are conducted, using a 6 degree of freedom model designed in Simulink environment and a 3 dimensional model of aircraft built in X-Plane 11 flight simulator. It is then further ammended and used to predict precision of trajectory of the aircraft analyzed, while controlled using the ArduPilot control algorithms. Results of this research are presented in graphical and text format. The hypothesis, stating that precise tuning of the control algorithms is possible using the aicraft's model „Volantex Ranger 2000”, designed in a virtual environment is confirmed. The flight trajectory of the digital model of analyzed aircraft, performed in a flight simulator closely resembles that of a real aircraft. Structure: introduction, the overview of simulation types and environments, analysis of results of recent papers in similar research topics, the investigation of the methodology of simulation environment and aircraft aerodynamic characteristics, the conclusions and suggestions for further research, references.
