Abstract:
Refueling docking at different velocities is simulated by using computational fluid dynamics (CFD) method. The Osher scheme and S-A turbulence model are used to solve the compressible Navier-Stokes equations, and the Delaunay mapping dynamic grid method is also employed. All the numerical results show that the velocity of refueling docking is very important for aerial refueling. When the velocity is lower than 3 m/s, the refueling drogue will move upward with obvious cycle staggering, while moving upward with slight cycle staggering at the speed of 3 m/s. The results can be referenced by aerial refueling design.
