Structural Analysis of Aluminum and FRP Composite Laminate for Iskra Aircraft Wing Using FEM

This study is dedicated to the replacement of traditional aluminum alloys with composite laminates of Fiber Reinforced Plastics (FRP), boasting strength-to-weight properties are similar. The primary focus of this research lies in conducting a meticulous structural analysis of an aircraft wing using the advanced Finite Element Analysis software ANSYS. The specific subject of analysis is the ISKRA Trainee 4-seater Aircraft wing, originally constructed from aluminum. The study entails a thorough comparison of theoretical results between the original aluminum structure and the alternative FRP composite laminates. The structural modeling of the wing is carried out via Finite Element Methods (FEM) within the ANSYS software environment, with the overarching objective of evaluating the feasibility of transitioning from traditional aluminum to composite materials. Moreover, the research provides a comprehensive, step-by-step insight into the systematic construction of crucial wing components, such as ribs, spars, and stringers, which are integral to the performance and safety of the PZL TS-11 wing. The use of CATIA V5, a recognized tool in aerospace engineering, is showcased through clear instructions and illustrative images, making this paper an invaluable resource for both novice and seasoned aerospace engineers seeking a profound understanding of the complexities involved in the creation of wings for this iconic aircraft.
