Nose landing gear

The customer

• Size: Large enterprise
• Sector: Aircraft manufacturing
• Country: France

The Project

• Size: 75-90 man-hours
• Duration: 4-5 weeks

The Problem

• Plastic deformations on some mechanism elements
• Early malfunction of the mechanism

Proposed solution

• Evaluate static stress under different cargo loads
• Assessment of maximum stress under landing conditions

The simulations

• Static stress analysis to find mechanical hotspots of the structure (FEA analysis)
• Dynamic impact analysis for landing conditions at maximum aircraft load (FEA analysis)

Project overall results

• Potential failure spots were located and re-design was adviced.
• Savings over £38,000 for the customer in prototyping and testing (estimate).
• Savings of more than 4 weeks in development time (estimate).
