Using XFlow software to simulate the trajectory of unmanned carrier-aircraft dropping unmanned sub-aircrafts and conducting flight tests. The results show that the experimental data is in good agreement with simulation data, sub-aircrafts deploy smoothly when dropped, the flight attitude is controllable, and sub-aircrafts can be safely separated from the carrier-aircraft.
