AIRFRAMES NOTES
4. LANDING GEAR DESIGN
4.1. Key Considerations
· Strength and Stability:
The landing gear must withstand the weight of the aircraft, including during taxiing, takeoff, and landing, as well as side loads.
· Ground Clearance:
Sufficient clearance between the landing gear and the ground is crucial to prevent damage to the aircraft or runway.
· Energy Absorption:
Landing gear systems are designed to absorb the energy of impact during landing, protecting the aircraft and its occupants.
· Retraction and Kinematics:
For retractable landing gear, the design must ensure smooth and reliable retraction and extension.
· Tire and Wheel Selection:
The type, size, and spacing of tires and wheels are critical for ground stability and performance.
· Braking Systems:
Effective braking systems are essential for controlling the aircraft on the ground.
· Steering:
Some landing gear systems include steering capabilities for maneuvering the aircraft on the ground.
· Regulatory Compliance:
Landing gear designs must meet stringent airworthiness regulations and safety standards.
· Operational Requirements:
The design must consider the specific operational requirements of the aircraft, such as the type of runways it will land on and the types of maneuvers it will perform.
· Material Selection:
The choice of materials for the landing gear must consider strength, weight, and resistance to wear and tear.
· Weight Reduction:
Engineers constantly strive to reduce the weight of landing gear systems without compromising performance or safety.
