In recent years, only unmanned aerial vehicles (UAVs) with small wingspans have used the wing modularization method, and for long-winged aircraft, continuous wings dominate the others. Regarding long-wing aircraft, it is complicated for manufacturers to make the whole wing intact and take the aircraft to take-off locations. With current technology, producing such a long and continuous wing is difficult, so it is essential to separate the wing into modules and fabricate them. Before using UAVs, operators need to assemble the parts of the wing together and reinforce the connected region. This will facilitate the shipping, assembly, operation, and maintenance of the UAVs. Meanwhile, this paper also provides an idea for the improvement of removable wing structure design and the simulation of new wing structural strength and endurance. The stress concentration at the connection locations is quite large and requires further study of the structure in these areas. We have found two main approaches: the conventional method using bolts and the new method using the magnetic lock. Although connecting by magnetic lock brings convenient benefits for operating, this approach is less stable in the section of the structure than the conventional one. Based on this research, we can optimize the wing structure and junction methods for the purpose of manufacturing and commercializing this product in the future.
