Real-time fixed-wing aircraft trajectory optimization subject to no-fly zones:
An innovative geometrical investigation method

Real-time trajectory optimization has gained significant attention due to its practical applications in enhancing task flexibility. Fixed-wing aircraft typically uses a combination of line segments and circular arcs, tangent at waypoints. Determining waypoints establishes the complete trajectory. Handling no-fly zones, categorized as circular plates or polygons, requires defining intersection conditions between the path (line segment or circular arc) and no-fly zone peripheries (line segment or circle). Traditional approaches lack thorough use of geometry, relying on trial-and-error methods, resulting in low efficiency. We propose unique geometric conditions for intersection determination, based on established conditions for point inclusion in parallelograms. Our method efficiently formulates the original problem into solvable conditions, demonstrating faster solving speeds and higher accuracy compared with existing algorithms. This approach smartly utilizes path and no-fly zone characteristics for more sophisticated problem-solving, departing from previous generalized frameworks.
