Simulation and analysis of aerodynamic characteristics of high-altitude long-distance gliding UUV (unmanned underwater vehicle)

In order to study the aerodynamic characteristics of the high-altitude long-distance gliding UUV, Sects. 2, 3 and 4 states the process of the analysis and research mentioned in the title, whose core consists of: "Under the environment of FULENT, defining the boundary conditions, meshing, solving the Navier-Stokes equations, completes the three-dimensional flow field numerical simulation of UUV under the condition of subsonic (Sect. 3). The longitudinal aerodynamic characteristics, lateral aerodynamic characteristics and the characteristics of the manipulation derivation properties are analyzed in Sect. 4." The simulation results, given in Figs. 3, 4, 5 and 6, show that the aerodynamic characteristics meet the requirements of the low draft characteristics of the aircraft and the static stability. Not only mentioned can conducive the next step of the manipulation of the aircraft, stability and ballistic characteristics, but also provide an important basis to further improve the design and model processing test.
