The invention provides a main wing retractable type fixed wing airplane which is a transportation vehicle capable of flying in the air. In order to solve the problems that an existing airplane cannot fly and descend in an economical and energy-saving manner, the design is carried out. The main wing retractable type fixed wing airplane is structurally characterized in that a specially-designed outrigger box and a fuselage cross beam are connected in a fastened manner and straightly stretch out of the two sides of a wing; a cantilever is used for bearing acting forces of sliding wing sections in all directions; the sliding wings on the two sides freely retract and slide in an outer sleeve wing on the surface of the outrigger box due to control and limitation of action cylinders; the wing expansion and the wing shape can be changed by flying speeds; a semi-driving type vertical fin is also designed to retract up and down to adjust the control area, so that the flying resistance of the whole airplane is reduced, and the adapting thrust is reduced; the main wing retractable type fixed wing airplane is economical, environment-friendly and safe, and the navigability also can be improved; in order to be adapted to the gravity center change caused by the speed change of the airplane, a gravity center adjusting vehicle mounted on a guide rail is designed, and a trimming power vehicle is controlled to move forwards and backwards to adjust the gravity center; and the part construction is shown as a figure of the specification in detail, and an airplane designing and manufacturing enterprise can produce the applicable product according to the design.
