By taking the tanker aircraft drogue as a research object

the fi nite element model of collision dynamic analysis is set up

and the dynamic simulation is performed on the collided process of the tanker aircraft drogue and the oil joint of tanker aircraft. The collision force between the tanker aircraft drogue and the oil joint is analyzed

as well as the structural stress of the tanker aircraft drogue and the tension of the position limit wire ropes among frames. The dynamic response rule of the tanker aircraft drogue in the collision process is investigated. In addition

the research points out the weakness which could result in the nonserviceable of the tanker aircraft drogue.
