Assignment Brief

Technical Report - Lightweight Fuselage Manufacturing and Analysis

For this coursework, you`ll work in groups on experimental activities with three tasks. Submit an individual report based on group findings.

1. Aeroelasticity

Simulate flight stress loadings on a CAD model using SolidWorks. Propose a laminating pattern and prepreg type.

2. UAV Fuselage Manufacturing

Apply prepreg stacking sequence to a foam-core fuselage tool in either a left or right mold.

3. Inspection

Inspect the final fuselage for weight, wing geometrical precision, and axial stiffness using a bending rig.

Technical Report

Report group findings (word limit: 3000 words), structured as follows:

• Section A: Lab Engagement Describe the lamination process and practical engagement.
• Section B: FEA Analysis Apply stress loading methodology and present stress results in table format.
• Section C: Bending Testing Report fuselage inspection results for weight, center of gravity, and stiffness.
• Section D: Reflection Reflect on experimental results, addressing discrepancies between theory and practice and proposing improvements.
