Design of UAV's External Fake Stores and Its Test Application
UAV has no risk of casualties,strong survival ability,good maneuvering characteristics,and so on,It plays an important role in modern war,and the kinds of external stores determine the UAV's military operational performance.In this paper,the external fake store of a certain UAV in its central wing was designed.The strength,stiffness and stability of the fake store have been analyzed by using Patran software,and the fake part was used to complete the static test of central wing in flight release status.The results show that the fake store can realize multiple directions and multi-point's loading.Under the typical load,the fake store's maximum stress which is located in the cen-ter of the connecting hole is 195 MPa,less than the yield stress of the material;the bottom of the fake store has bending deformation and the maximum deformation is 0.3 mm,less than the design require-ment of 0.5 mm.Under the release load,the effect of stores on the wing deformation is consistent with the theoretical value.It offered a reference for stores the analogous UAV store design and its static test.
