The Delaunay method is briefly introduced, which is one of the widely used unstructured mesh generation methods in computational fluid dynamics. In order to facilitate practical application, this paper simplifies the conditions of free flight, and then discusses the data processing of Delaunay method for conflict detection in detail. This method can detect collisions and potential conflicts between multiple aircraft at the same time and reduce the unnecessary distance detection, thus reducing the computational cost. Finally, the flight simulations of several aircraft in airspace are carried out to prove the effectiveness of the method in collision detection.
