| 摘要: |
| 空中安全分离是评价中低速组合体飞行器飞行性能的重要指标。针对组合体飞行器空中分离问题，引入影响箱及安全分离走廊的概念，提出一种快速获取组合体飞行器安全分离区域的数值方法：影响箱-走廊法，并采用该方法对某组合体飞行器的适宜分离区域生成进行研究。对某型号组合体飞行器的分离过程进行了介绍及简化；阐述了影响箱、安全分离走廊的概念及影响箱-走廊法的逻辑及流程；在此基础上，通过数值仿真的方式，确定某组合体飞行器的单体安全分离区域；对该方法应用于飞行器空中实时分离等领域进行了延伸介绍。 |

| Abstract: |
| Aerial safety separation is an important indicator to evaluate the flight performance of medium and low speed combination aircraft. In this paper, the concept of impact box and safe separation corridor will be introduced for the air separation problem of the composite aircraft, and a numerical method for quickly obtaining the safe separation area of the composite aircraft is proposed:the influence box-corridor method, and the suitable separation area generation of a composite aircraft will be studied by this method. The article introduces and simplifies the separation process of a certain type of combined aircraft. The concept of impact box and safe separation corridor and the logic and process of the impact box-corridor method are expounded. On this basis, the method is applied to determine the safe separation area of a single body of a composite aircraft through numerical simulation. Finally, the application of this method to the field of real-time separation of aircraft is extended. |
