Cargo airdrop has long been one of the most important measures to deal with urgent immediate needs, such as providing assists in military operations and sending relief to disaster areas, just to name a few. Because it is carried out during flight, it is necessary to investigate the influences of the drop process on flight characteristics to ensure successful execution of the task. This article mainly studies the modeling of flight systems in large flying transport planes with cargo moving in it. By building up rational frame definition, the complete nonlinear force and moment equations are established by using the Newton's second law and the Euler angle relation of rigid body. Then the effects of moving process parameters including cargo mass and moving items upon the flight are analyzed. Computerized simulation of the whole process shows that the cargo moving would exert enormous effects upon the flight characteristics and quality of controlling; therefore, a special control strategy should be developed to guarantee the required system performances.
