Convex optimization has gained increasing popularity in trajectory planning methods for wide-speed range unmanned aerial systems (UASs) with multiple no-fly zones (NFZs) the entry phase. To address issues of slow or even infeasible solutions, a modified fast method using approaches variable trust regions and adaptive generated initial values is proposed this paper. A dimensionless energy-based dynamics model detailing constraints phase utilized to formulate original problem. This problem then transformed into finite-dimensional convex programming problem, techniques such as successive linearization interval trapezoidal discretization. Finally, region strategy an value generation are adopted accelerate solving process complex flight environments. The experimental results imply that paper can significantly reduce solution time UASs
