Numerical analysis and material Determination of Cessna 150 Aircraft using FSI Analysis Method

Nowadays, Light aircrafts play key role in the aviation industry. Therefore, it is important to select the right equipment in airplane propulsion system. In this paper, at first, airplane propulsion system blades are designed in SOLIDWORKS software, then they are analyzed in ANSYS software using fluid-structure interaction analysis (FSI) method. The blades pressure contours under various conditions obtained in ANSYS fluent software. After that, the output data of analysis in fluent software is transferred to ANSYS static structural to perform tension and deflection analysis of blades. The results demonstrate the sections which are near the blade tip are imposed by higher pressure than other sections. For determination of blade material, three materials such as stainless steel, copper and aluminum have been chosen as blade material. At next, deflection and stress applied to each blade with different material are compared with each other. The stress and deflection values were calculated based on van Mises criteria and maximum deflection. By comparing the values of stress and deflection of each blade made by mentioned materials, the blade made by stainless steel which has the lowest deflection was selected as the best material.
