In this paper, a model for the design of the tail rotor of a helicopter is developed. In particular, a CAD-MBD-FEM approach was employed to this end. The starting point of the analysis is the virtual development of the virtual model. Once the virtual prototype was made, it was reworked to make the multibody model, developed through the combined use of MATLAB and SIMULINK, by using the SIMSCAPE MULTIBODY toolbox. The main purpose of this analysis is to calculate the forces that are transferred to the various components in each operating configuration. Finally, the last part of the design strategy focuses on the FEM analysis carried out in ABAQUS. To this end, the output of the multibody analysis is used as input for the subsequent FEM analysis, and this was done in order to determine if the component is statically verified or not.

Abstract
In this paper, a model for the design of the tail rotor of a helicopter is developed. In particular, a CAD-MBD-FEM approach was employed to this end. The starting point of the analysis is the virtual development of the virtual model. Once the virtual prototype was made, it was reworked to make the multibody model, developed through the combined use of MATLAB and SIMULINK, by using the SIMSCAPE MULTIBODY toolbox. The main purpose of this analysis is to calculate the forces that are transferred to the various components in each operating configuration. Finally, the last part of the design strategy focuses on the FEM analysis carried out in ABAQUS. To this end, the output of the multibody analysis is used as input for the subsequent FEM analysis, and this was done in order to determine if the component is statically verified or not.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
