Abstract:The movement of loading door retraction mechanism with slide track ol an airplane is investigated. The mathematical model is established on. the basis of selected geometrical parameters of the mechanism. The retracting movement of the loading door is simulated on a digital computer with the coordinates of the moving points computed step by step. The process of retraction is displayed on the screen for the examination of the fulfilment of design requirements. Adjustment of parameters can be made if necessary during the computation.
Keywords:loading door retractable mechanism  computer simulation  spline bit  point by point solution
