Abstract

The accuracy of UAV deployment is influenced by operational techniques, flight conditions, and environmental factors (e.g., altitude, speed, wind speed). This paper conducts research using kinematics, aerodynamics, differential equations, and optimization methods. A 3D coordinate system and differential equation system are established to analyze the relationship between deployment distance and key factors, with distances calculated under three wind directions (0${^\circ}$, 90${^\circ}$, 180${^\circ}$). Based on kinematics and aerodynamics, a model with four variables (launch distance, altitude, dive angle, landing time) is built. Using linear programming combined with entropy weight method, the optimal strategy is obtained: dive angle 3${^\circ}$, launch distance 1005.01 m, flight altitude 717 m, landing time 10.9 s. Introducing dive/roll angles as attitude parameters, a target programming model solved by genetic algorithm yields optimal angles (2.56${^\circ}$, 3.48${^\circ}$). Verified via Lyapunov function and regression ($R^2=0.8388$), the random forest model achieves a higher $R^2$ of 0.9899.
