| description | The invention belongs to the field of aerodynamic layout design of aircrafts, and particularly relates to a method for improving pitching characteristic of a camber-free double-vertical-fin layout. The pitching characteristic of the camber-free double-vertical-fin layout can be improved by controlling the deflection of a horizontal tail and a vertical fin (1) or the deflection of the horizontal tail and a rudder (2). According to the method for improving the pitching characteristic of the camber-free double-vertical-fin layout, the head lowering control capability of an aircraft with the camber-free double-vertical-fin layout at a large angle of attack can be improved, and the method is also suitable for improving the head lowering control capability of the aircraft with the camber-free double-vertical-fin layout at a small and medium angle of attack. According to the method, on the premise that the aerodynamic layout of the aircraft is not modified, the high-attack-angle head lowering and head raising contro |
