Abstract:
The design of semi-monocoque frame by using the composite-steel joint is considered in this paper. The frame is designed with weight less than 30kg and torsional stiffness more than 1200 Nm/deg. In order to design the semi-monocoque frame, the analysis of the composite-steel joint has to be clearly investigated. Therefore, the stress analysis of composite-steel joint is performed and then the frame is designed. The double lab joint with two holes is tested and verified by the experiments. The carbon-fiber fabric laminated with the KEVLAR fabric composite laminate is used for composite part. Fr

Abstract - The structural integrity and performance of an aircraft fuselage are critical factors in aerospace engineering. This project focuses on the modelling and analysis of a semi-monocoque aircraft fuselage structure, a widely used design due to its high strength-to-weight ratio and efficient load distribution. The study involves creating a finite element model (FEM) of the fuselage to simulate real-world loading conditions, including aerodynamic forces, internal pressurization, and structural stresses. Various materials and geometries are considered to optimize weight, strength, and dura

For repairing punctures of skin of semi-monocoque structures under field conditions, simple methods are sought to guarantee the reliability of the repaired structure.

Stress analysis of such closed thin-walled structures which are statically indeterminate is tedious and time consuming. An educational software which can aid students in carrying out stress analysis of such idealized thin-walled closed sections has been developed. The software enables students to select different types of wing torsion box sections with stiffeners, which may be subjected to bending, shear or torsional loads and evaluate the resulting stresses o

But as metal designs have reached a high degree of perfection, extraordinary weight and cost savings are unlikely in the future.

During aircraft service, the skin is the component that first comes into contact with factors that can cause mechanical damage - that is why it is most often damaged during use. Semi-monocoque aircraft structures are made of a skin (usually aluminum alloy) and a frame. The skin is an element that significantly affects the safety of the structure, since it transfers loads between the elements of the frame. For this reason, the skin is subject to special supervision during technical maintenance, and any damage detected must be repaired. The research was carried out on specimens made of AW 2024-T
