Abstract (Croatian)

U ovom diplomskom radu definiran je kvazistacionarni model dinamike mahanja kraka rotora odabranog helikoptera. Definirane su analitički integrirane jednadžbe aerodinamičkih sila i momenata koje proizvodi rotor helikoptera. Provedena je analiza utjecaja aerodinamičkih i inercijskih značajki rotora na dinamiku mahanja. Kvazistacionarni model dinamike mahanja uspoređen je sa sličnim modelima, te su rezultati te analize uspoređeni s rezultatima nastalim mjerenjem u letu promatranog helikoptera. Kvazistacionarni model dinamike mahanja kraka rotora primijenjen je na model repnog rotora. Model kvazistacionarne dinamike leta uključen je u 6DOF model leta helikoptera.

Abstract

In this master's thesis quasi-steady rotor blade flapping dynamics model is defined for the selected helicopter. The analytic integrated equations of aerodynamic forces and moments produced by the helicopter rotor are defined. It is defined analysis of the influence of the aerodynamic and inertial characteristics of the rotor flapping dynamics. Quasi-steady rotor flapping dynamics model is compared with similar models, and the results of that analysis were compared with results achieved in measurements of helicopter flihgt. Quasi-steady rotor flapping dynamics model was applied to the tail rotor model. Quasi-steady rotor flapping dynamics model was included in the 6DOF helicopter flight model.
