Design Analysis and Fabrication of the Aircraft Landing Gear

Designing a landing gear of an aircraft for sustaining structural integrity and performance is the key concept in aircraft engineering which helps in guaranteeing safe take-offs and landings. The components like shock absorbers, lug joints, and torque links considerably effect durability of landing gear. Materials like titanium alloys, high speed steel, aluminium alloys, AISI steel and carbon fiber-reinforced polymer are the frequently used materials with their own strengths and limitations. Although titanium alloys offer superior strength-to-weight ratios, they are more expensive than aluminum alloys, which are more cost-effective but could not be as strong when subjected to extreme stress. CFRP materials improve mechanical qualities while lowering weight. The requirement for exact design and careful analysis is highlighted by the fact that landing gear failures are frequently caused by material fatigue, excessive loads, or incorrect assembly. The use of the Finite Element Method (FEM) improves reliability, ensuring greater safety and efficiency in modern aircraft. This research focuses on developing and assessing the structural integrity of aircraft landing gear, followed by building and testing a prototype to evaluate its performance.
