This work addresses three-dimensional path planning for unmanned aerial vehicles (UAVs) subject to kinematic constraints. We propose a multi-objective particle swarm optimization (MOPSO) method employing navigation-variable encoding, where heading angle and curvature—dynamics-sensitive quantities—are explicitly modeled as decision variables. A parameterized trajectory representation is constructed and embedded with kinematic constraints, enabling direct generation of feasible trajectories and high-quality convergence to the Pareto front. Compared with NSGA-II and RRT*, our approach achieves a 37% improvement in path success rate and a 29% reduction in computational time in complex 3D environments. All generated trajectories strictly satisfy maximum turn-rate and acceleration constraints. Moreover, the method attains superior trade-offs among safety, trajectory smoothness, and energy efficiency.
