Abstract

This thesis presents a comprehensive approach to developing and tuning a helicopter flight model for simulation of flight performance, with a focus on a prototype helicopter under development. Conducted at Zürich University of Applied Sciences (ZHAW), the research involves several key tasks aimed at refining the model to achieve satisfactory similarity with real-flight data. The thesis begins with a description of the helicopter flight model and its relevant sub-models, including aerodynamics, propulsion, controls, and dynamics. Subsequently, potential tunable parameters for the model are identified through analysis of its components. These parameters are then subjected to sensitivity analysis to understand their impact on stability and overall flight characteristics. Based on the sensitivity analysis results, recommendations are made for a list of parameters deemed suitable for tuning the helicopter flight model. The criteria for evaluation encompass the significance of each parameter in influencing flight performance and the feasibility of adjusting them to match real-flight behavior. This research contributes to the advancement of helicopter flight modeling by providing a systematic methodology for parameter identification, sensitivity analysis, and model tuning. The findings offer insights into enhancing the fidelity of helicopter simulation models, with implications for various applications including training, research, and development.

Abstract (croatian)

Ovaj rad predstavlja sveobuhvatan pristup razvoju i podešavanju modela leta helikoptera za simulaciju leta, s fokusom na prototip helikoptera u razvoju. Provedeno na Zurich University of Applied Science (ZHAW), istraživanje uključuje nekoliko ključnih zadataka s ciljem usavršavanja modela kako bi se postigla zadovoljavajuća sličnost s podacima stvarnog leta. Rad započinje opisom modela leta helikoptera i pripadajućih podmodela, uključujući aerodinamiku, pogon, upravljanje i dinamiku. Naknadno, potencijalni prilagodljivi parametri za model identificiraju se kroz analizu njegovih komponenti. Ti parametri potom su podvrgnuti analizi osjetljivosti kako bi se razumio njihov utjecaj na stabilnost i ukupne karakteristike leta. Na temelju rezultata analize osjetljivosti, donosi se popis parametara koji se smatraju prikladnima za podešavanje modela leta helikoptera. Kriteriji za ocijenjivanje obuhvaćaju značaj utjecaja svakog parametra na dinamiku leta i letnih performansi te provedbu prilagodbe usklađivanja s ponašanjem u stvarnom letu. Ovo istraživanje doprinosi napretku modeliranja leta helikoptera pružajući sustavnu metodologiju za identifikaciju parametara, analizu osjetljivosti i podešavanje modela. Dobiveni rezultati nude uvide u poboljšanje vjernosti modela simulacije helikoptera, s implikacijama za različite primjene, uključujući obuku, istraživanje i razvoj.
