Avionic System Component Design

Project Overview

This repository contains the design files for an Avionic System Component, a lightweight bracket modeled in Siemens NX 12 for aerospace applications. The design features triangular cutouts for weight reduction (approximately 30-40%) while ensuring structural integrity, with precise mounting holes and fillets for stress relief. This project serves as a skill-building exercise focusing on CAD/CAM precision and manufacturability.

Key Design Features

• Dimensions: 124.9 mm (L) x 75.7 mm (W) x 10 mm (H), all in mm.
• Weight Optimization: Triangular cutouts reduce mass effectively.
• Mounting: Four Ø11.6 mm holes for secure fastening.
• Fillets: R3 and R6 for stress concentration mitigation.

Tools and Software Used

• Primary: Siemens NX 12 for 3D modeling and 2D drafting.
• Skills Applied: Extrusion, patterning, boolean operations, filleting, and GD&T.
