Análise de uma falha crônica presente nos amortecedores de impacto das aeronaves Piper PA-30 Twin Comanche e sugestões para solucionar o problema

Abstract

This project presents an evaluation of a chronic failure present in the shock struts of the main landing gear of Piper PA-30 Twin Comanche aircrafts, starting with a review of the operation and maintenance of these parts. A shock strut from the right-hand landing gear of a Twin Comanche was acquired as the object of analysis for this project, which also presents a theoretical basis on failure analysis techniques, which were carried out in the experimental section to characterize the part material and determine the failure mode thereof. Finally, finite element analysis technique was employed to suggest a solution to fix the failure present in these shock struts. In addition, it is expected that this project will contribute both to the field of aeronautics industry as to the field of engineering, for it is a scarce theme in the literature that addresses from the investigation of a real chronic failure to its correction.
