Aircraft Structures – 2: The Fuselage of a Light Aircraft

Introduction:

In this post, a light aircraft fuselage was designed from scratch in a 5-6 hour effort (see Figure-1) and the corner points (see Figure-3) were transferred to Excel, and connection tables were created to obtain the finite element solution mesh shown in Figure-4. After selecting appropriate loads and boundary conditions, analysis was performed, and each load on every element can be examined to optimize the structure of the fuselage.

Note: Whether or not structural analysis and optimization will be carried out depends on the level of interest and participation in the topic. I look forward to your contributions…
