A computer program is developed for the kinematic synthesis of a landing gear retraction four-bar mechanism. The software incorporates a graphical user interface and generates various four-bar linkages that fulfill the required wheel position on the ground and in the bay, ensuring they fit within the available aircraft stowage volume. To accommodate configurations where retracting landing gear around a single axis is insufficient, the system introduces secondary motion, such as additional translation or rotation. For design cases necessitating wheel rotation, the program performs retraction involving motion in two planes. The computer software, integrated with Siemens NX, creates potential four-bar retraction mechanism linkages, allowing users to visualize the resulting mechanism and assess its design and manufacturability aspects.
