This paper presents a wrench-based evaluation framework for an adjustable Aerial Cable-Towed System (ACTS), focusing on its capability to generate feasible force and torque combinations under various operational configurations. The ACTS under study consists of three quadrotors, each capable of continuously adjusting the aerial platform’s elevation and azimuth angles. By analyzing the system’s wrench space, its performances are assessed across dynamic trajectory scenario by using capacity margin. The evaluation emphasizes the impact of adjusting the elevation and azimuth angles of the aerial platform to the cable tension while maximizing payload capacity and maneuverability. Results indicate that strategic modulation of the azimuth angle significantly enhances wrench generation capabilities, as shown by increased payload capacities and a higher capacity margin. The dynamic azimuth adjustment effectively minimizes tension loads, validating the potential of wrench-based metrics as a robust tool for optimizing aerial cable-towed operations.
