Method for improving aerodynamic interference resistance of carrier rocket

A method for improving the aerodynamic interference resistance of a carrier rocket comprises the steps that (1) a load shedding trajectory program angle is generated before launching, and meanwhile a rolling program angle is corrected, so that the maximum control force direction of a rocket body is aligned with the actually-measured wind direction before launching in the flight process; (2) in an allowable rolling correction interval, observing the normal and transverse apparent accelerations of which the lever arm effect is deducted by adopting an observer; (3) obtaining transverse and normal pneumatic disturbing forces by using the apparent acceleration from which the lever arm effect is deducted, and dividing the pneumatic disturbing forces by an aerodynamic coefficient to obtain an airflow attack angle and a sideslip angle; and (4) calculating an airflow total attack angle, and judging whether the total attack angle exceeds a threshold value or not. When the total attack angle exceeds the threshold value,
