A fuzzy network method for the airfoil long baseline antenna deformation measurement

The development of high-altitude long-endurance unmanned aerial vehicle (UAV) is receiving more and more attention, and a high precision deformation measurement in real time of the airfoil long baseline antenna is of great significance to ensure the antenna performance. According to the theory of fuzzy self-structure, a self-structuring fuzzy network deformation measurement (SSFNDM) which is suitable for the real-time measurement of the airfoil deformation is proposed to build a network to approximate the relationship between the strain and the displacement automatically. A deformation measurement experiment on the aluminum airfoil model under static load is also presented. The results show that the SSFNDM has a high accuracy and a fast speed for training to provide a new way for the airfoil deformation measurements.
