DragDirection offlightThe weight of the wing was not considered in the calculations, butthe lift that its producing was considered. By this consideration wehave increased the safety factor of both the hinge and the bearingtogether.The length of the connecting rods and the angles were determined ina way that the wings will be on the same line in the openedconfiguration.In order to choose the spring and to perform the calculations, weused the sizes of the rods and their angle's position.CHOOSING OF THE MAIN SPRING:MECHANISM COMPONENTSThe spring's mechanism is made up of: a spring, a rod which on topof it the spring is placed and a pin which leads the spring on top ofthe rod and attached to the connecting rods. The whole mechanism isplaced in track on a coordinating surface.The spring is stretched while the wings are folded. While launchingthe UAV, the spring is released and opens the wings.26
