Abstract

Predmet završnog rada sadrži generalni opis sustava za mjerenje sila i momenata, u zračnom tunelu Fakulteta prometnih znanosti, i njegovih komponenti. Također, detaljno će biti razrađen proces osmišljavanja i dizajna aerodinamičkih modela, njihove dimenzije i karakteristike te sami način ugradnje modela u zračni tunel. Navedena su ograničenja zračnog tunela, kao i ograničenja aerodinamičkih modela u smislu maksimalnog napadnog kuta i maksimalnog kuta klizanja. Nadalje, pomoću računalnog programa, simulirane su usporedbe aerodinamičkih karakteristika modela aeroprofila pri raznim konfiguracijama modela, poput promjene napadnog kuta i spuštanja zakrilaca, ali i zračnog tunela, promjenom brzine strujanja zraka.

Abstract (english)

Subject of the thesis involves a general explanation of the force and moment measuring system present in the Faculty of traffic and transport sciences wind tunnel, as well as its components. Furthermore, the process of aerodynamic model design, their dimensions and characteristics, as well as the method of installing the model inside the wind tunnel, will be elaborated in detail. Wind tunnel limits are listed, along with the limits of aerodynamic models in terms of maximum angle of attack and maximum sideslip angle. Additionally, with the use of a computer program, simulated aerodynamic characteristics of airfoil models have been compared at various configurations, such as changing the angle of attack and lowering the flaps, but also at various configurations of the wind tunnel, like changing the air velocity.
