For optimization of the modular reconfigurable airfoil structures, three wing modules that distributed along the span direction are taken as research object, and the correlations of load among airfoils with different wingspan are investigated. The complex coupling effects between variables and constraints are resolved by adjusting the design space during iteration automatically. A step-compensation optimization method is proposed for design of the modular reconfigurable airfoil structure. Optimization model of airfoil structures from a modular UAV is established and optimization design is conducted using both the step-compensation method and the traditional single scheme optimization method. The results show that using the proposed method can achieve steady convergence, and compared with the results from single scheme optimization method, the final design in this paper can meet all the design requirements of those three reconfiguration schemes with limited cost of weight, and keep better practicability in engineering.
