Abstract

U diplomskom radu prikazan je postupak izrade i implementacija modela leta temeljenog na modelu gibanja materijalne točke. Prikazane su sve potrebne geometrijske i aerodinamičke karakteristike razmatranog helikoptera Bo105, te su opisana dva različita načina proračuna ravnotežnog leta helikoptera. Prvi proračun izvršen je prema Van Hoydonck-u, te je za njega potrebno manje računalnih resursa od drugog proračuna prema Bramwell-u, koji pruža kompletniju i precizniju sliku parametara ravnotežnog... More leta. Nadalje, proračun prema Bramwell-u dodatno prikazuje i rezultate za bočnu ravnotežu. Opisan je postupak implementacije parametara ravnotežnog leta u model leta te je prikazana izrada dva modela leta različite kompleksnosti. Za oba modela su provedene demonstracije složene trajektorije za koje su prikazani rezultati. Less

Abstract (english)

Main topic of this master's thesis is the process of creation and implementation of a helicopter flight model based on point mass model. Helicopter used as example in the thesis is Bo105, whose aerodynamic and geometric parameters were shown, as well as two different approaches to calculation of the helicopter trim conditions. First approach to trim was done according to Van Hoydonck, which was less complex and thus faster than the second approach, which was done according to Bramwell.... More However, Bramwell's approach turned to be more precise and complete. Also, it included calculation of lateral trim. Implementation of trim conditions to the model were described, and two models of different complexity were created and explained. In the end, both models have been tested and the results of flight parameters were shown and analysed. Less
