A real-time simulation software is proposed to simulate the sequential extraction airdroping cargoes from aircraft based on the real-time simulation requirement. The basic subprogram module of the software consists of simplified mathmatical models and simplifiedsubroutine of the moving cargoes. The test results are given and comprared with digital simulation solutions of nonlinear differential equations. The test results show that the softwaredesigning is reasonable and its functions are relatively well. as for the reality, real-time andprecision of simulation. The requirement of real-time and precision are resolved relativelywell. With this software we can carry out the simulation study on the control--stability of se quential airdroping of cargo from aircraft and the safety. And it can be used as the simulationof flight training.
