The multi-section chain tiltrotor aircraft possesses diverse body configurations, rich combination transformation sequences, and non-unique configuration solution sets. To enable the aircraft to achieve optimal flight performance and mission accomplishment schemes under varying mission conditions, thereby enhancing its variant execution efficiency and mission adaptability, this study investigates the configuration reconstruction and strategy of multi-link tiltrotor aircraft. Initially, the attributes of the multi-section chain tiltrotor aircraft were analyzed, identifying three key factors: passability, stability, and energy consumption, as evaluation indexes for the reconstruction strategy. Subsequently, the weights of each index were determined using analytic hierarchy process(AHP) analysis, and a reconstruction decision-making method was established based on the weighted average approach. Finally, the effectiveness and scientific validity of the reconstruction strategy were verified through simulation. The results indicated that the reconstruction strategy increased the comprehensive score by an average of 26.87%, effectively enhancing the aircraft's performance, particularly in terms of passability and stability. These findings suggest that the proposed reconstruction strategy not only improves the adaptability of the aircraft in complex environments but also provides a significant theoretical foundation and practical guidance for the advancement of drone technology in various applications.
