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.
