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.
