Failure Analysis and Enhancements of Cessna-172 Nose Landing Gear Fork

Landing gear provides crucial support for aircraft while on ground. It is fastened to the main structural parts of the plane. The nose landing gear transfers all ground stresses to the aircraft structure, while the aircraft is on ground. Standard airplanes have main gears and the nose gear when taxiing on the ground the nose wheel is essential for both landing safely and guiding the plane. Main landing gear is to facilitate the safe touchdown of the aircraft. When combined, the main landing gear and the nose landing gear allow for landing smooth and jerk-free. The whole weight of the aircraft is supported by the undercarriage during taxiing and landing. Using the modelling program, a design and precise geometry of the existing Cessna 172 nose landing gear fork was created as well as for the proposed model of the nose landing gear. Comparison of four different materials for nose landing gear fork structures and evaluate the equivalent stress, strain and deflection was done. There is comparison of the nose landing gear fork structure with existing and proposed model. Compared to all the cases the titanium alloy material receives the lesser and nearer to the deformation of the steel.
