The following paper aims to present the fundamental aspects of the helicopter main transmission and its further dynamic analysis. The first part of the paper can be seen as a preliminary description of the world of helicopters, with a focus on the main transmission. Thus, the components that characterize it and the different controls to perform flight maneuvers are described. The main transmission described in the paper is a virtual prototype designed in the SOLIDWORKS environment. Having finished this purely descriptive analysis, the focus is placed on the heart of the work, namely, the dynamic analysis. To this end, the transmission modeling is carried out in a multibody environment, more specifically through MATLAB/SIMULINK. The evaluation of the force field exerted to the mechanism is carried out using the aerodynamic coefficients CL and CD, whose values are derived through XFOIL aerodynamic simulation software.

Abstract

The following paper aims to present the fundamental aspects of the helicopter main transmission and its further dynamic analysis. The first part of the paper can be seen as a preliminary description of the world of helicopters, with a focus on the main transmission. Thus, the components that characterize it and the different controls to perform flight maneuvers are described. The main transmission described in the paper is a virtual prototype designed in the SOLIDWORKS environment. Having finished this purely descriptive analysis, the focus is placed on the heart of the work, namely, the dynamic analysis. To this end, the transmission modeling is carried out in a multibody environment, more specifically through MATLAB/SIMULINK. The evaluation of the force field exerted to the mechanism is carried out using the aerodynamic coefficients CL and CD, whose values are derived through XFOIL aerodynamic simulation software.
