Abstract:

Hose whipping phenomenon has been a serious constraint to the success rate and security of aerial refueling. Dynamics of the hose whipping phenomenon is extremely complex due to the rigid-flexibility-liquid-coupled structure, and there is no accurate modeling and analysis methods which restricts the effectiveness of the existing suppression methods. To analyze the dynamic characteristics of the hose whipping phenomenon, based on lumped parameter rigid multi-body dynamics, a dynamic model of the elastic and variable-length hose-drogue assembly is built. The hose is modeled by a sequence of variable-length links connected with frictionless joints, and the masses and loads of each link are concentrated at the joints. A set of governing equations of motion is recursively derived subject to internal and external factors, such as hose restoring force due to bending, reeling in/out of hose, tanker transport motion, gravity, steady wind, atmospheric turbulence and tanker wake. The effects of factors of different closure speed profiles, different hose lengths and the tensator control on dynamics of the hose whipping phenomenon are analyzed by simulation. The results show that the degree of the hose whipping phenomenon induced by coupling is lower when the closure speed profile is gentler and the hose length is shorter. The dominating reasons why the tensator arouses the simple harmonic vibration-typed hose whipping phenomenon lie in the limited control range of the hose length, the time-lag effect of control and mismatch the closure speed of the receiver.
