Development of flight model for a general aviation airplane and its aplication for flight simulator

Glavni cilj ovoga rada bio je izrada modela leta zrakoplova Cessna 172 i dobivanje simulacije leta u realnom vremenu koristeći za to namijenjen softver i sklopovlje. U tu svrhu prikupljeni su podaci o masenim i geometrijskim karakteristikama navedenog zrakoplova, odabrani su izvori iz kojih su preuzeti modeli aerodinamike, inercije i motora te je provedena implementacija tih modela u postojeći model leta u MATLAB-u i SIMULINK-u. Isto tako, unaprijeđen je način razmjene podataka između MATLAB-a i SIMULINK-a. U svrhu provjere značajki razrađenog modela leta provedeni su ispitni letovi na simulatoru prilikom kojih su prikupljeni objektivni podaci, ali i subjektivne ocjene ispitnih pilota. Napravljena je i cjelovita priprema za snimanje leta u pravom zrakoplovu, koji zbog objektivnih razloga nije bilo moguće izvesti u roku za izradu ovog rada. Rezultati dobiveni analizom subjektivnih i objektivnih podataka prikupljenih tijekom ispitnih letova u simulatoru prikazani su i detaljno opisani, a na temelju njih provedena je i ocjena kvalitete upravljanja zrakoplova. Rad završava iznošenjem zaključaka formuliranih na temelju dobivenih rezultata.The main goal of this master thesis was to construct the flight model of a Cessna 172 aircraft and obtain a flight simulation in real-time, using the intended software and hardware. For that purpose, data about mass and geometric characteristics of the said plane was gathered. Furthermore, the sources, from which the aerodynamics, inertia and motor models were taken, have been selected, and said models were implemented in the existing flight model in MATLAB and SIMULINK. In addition, the data exchange between MATLAB and SIMULINK was improved. In order to verify the developed flight model, test flights in the simulator were conducted, from which both objective data and subjective evaluation from testing pilots were collected. A complete preparation was made in order to carry out flight recordings in a real airplane, which for objective reasons have not been realized before the thesis deadline. The results that were acquired by analysing the subjective and objective data during the simulator test flights are shown and described in detail, and were used to construct an assessment of handling qualities. The thesis is finalized by bringing forth the conclusions formed from the gathered data
