Stress and Deformation Analysis of Shaft-less Engine Fan

Abstract

Shaft-less experimental turbofan engine represents a unique conceptual design, with elements of simplicity and efficiency. This study deals with the most important part of the engine responsible for generating a large part of its tensile force - the fan. In this case too, it is a heavily loaded component. Combinations of different types of loads place great emphasis on its design. For verification and design of suitable geometry, stress and strain analysis was performed using the finite element method, which proved the resistance of the proposed solution under static load conditions. In the next step it is necessary to check the designed design also for the conditions of dynamic stress during engine life. The results of the above mentioned analyzes presuppose the successful realization and safe operation of the prototype shaft-less turbofan engine.
