Method for measuring mass center of large-wing aircraft

The invention relates to a method for measuring the mass center of a large-wing aircraft, and the method comprises the steps: placing a to-be-measured aircraft on mass and mass center measurement equipment, and reading the mass of the to-be-measured aircraft; defining an aircraft coordinate system as a left-hand system three-dimensional coordinate system, taking the head of the aircraft as an original point, and taking the inverse course of the aircraft as an x axis; solving the moment of the y axis through an unbalanced moment method to obtain an axial centroid xc; solving the moment of the x axis through an unbalanced moment method to obtain an axial centroid yc; respectively rotating the aircraft to be measured anticlockwise and clockwise around the x axis, and obtaining corresponding centroids xc1 and xc2 according to the method of the previous two steps; centroids yc1 and yc2; and calculating the radial centroid zc of the flight to be measured. The problem that the mass center cannot be measured due to t
