The article discusses how to ensure safe distances between different parts of a combined aircraft during flight. The researchers introduce the concept of an impact box and safe separation corridor to address this issue. They propose a method called the influence box-corridor method to quickly determine the safe separation area of a combined aircraft. By applying this method, they were able to generate suitable separation areas for a composite aircraft. The study simplifies the separation process for a specific type of combined aircraft and demonstrates the effectiveness of the impact box-corridor method through numerical simulations. Ultimately, this method can be used to improve real-time separation of aircraft in the future.
