The Ballet & How Aircraft Tuck Away Their Landing Gear We marvel at aircraft soaring through the sky, but rarely do we consider the intricate mechanics that allow it to retract its landing gear. It's a feat of engineering that involves complex systems of hydraulics, linkages, and actuators working in perfect harmony. The Aircraft landing gear doesn't simply disappear; it folds and rotates into designated compartments within the wings or fuselage using such engineering as: * Reaction Links are the Geometry of Motion: These translate the linear motion of hydraulic actuators into the complex, multi-axis movements required to fold the landing gear. They act like a system of levers, guiding the gear along a path as it retracts. * Shortening Links: In some aircraft, shortening links are employed to reduce the length of the landing gear strut during retraction. This allows the gear to fit into tighter spaces within the aircraft structure. Landing gear isn't just about wheels and tires; it's a complex system designed to withstand immense forces: Landing gear components are built to endure the impact of landings, the weight of the aircraft during taxiing, and the stress of takeoff. * Pivotal Points: The entire weight of the aircraft rests on a few pivotal points within the landing gear structure. These points are engineered to distribute the load and ensure structural integrity. * Braking and the Gyroscopic Effect: The landing gear incorporates powerful braking systems. While these brakes are essential for decelerating the aircraft upon landing, they also play a crucial role during the retraction process. Aircraft wheels, especially those of larger aircraft, can exhibit a significant gyroscopic effect when spinning at high speeds. Since the main landing gear often retracts at a 90-degree angle to the rotating wheels, this creates a gyroscopic moment that can put stress on the system. Applying brakes during retraction helps to reduce these forces, ensuring a smoother and safer retraction. The retraction process activates a hydraulic system that: * Unlocks the Gear: Releases the locking mechanisms that secure the landing gear in the down position. * Actuates the Folding Mechanism: Powers the hydraulic actuators that drive the reaction links or shortening links, causing the gear to fold and rotate. * Locks the Gear in Place: Secures the retracted landing gear to prevent it from deploying during flight.
