Rectification structure of twin-engine airplane after-body

The utility model relates to a rectification structure of a twin-engine airplane after-body, belonging to the technical field of pneumatic layout designs of aircrafts. The rectification structure comprises a rear rectification end surface (1), a lower rectification surface (2) and an upper rectification surface (4) which are formed into an externally-sealed rectification structure together with after-body engine covers (3). By using the rectification structure, a rectification appearance between the two engine covers of an airplane can be kept at a smaller diminishing angle, so that air flows on the upper surface and lower surface of the airplane can be prevented from separating; and the rectification structure is larger in height and space so as to be beneficial to the reduction of the structural weight and the increase of the structural strength.
