An arresting gear for quickly decelerating a moving object includes an elongated shaft that defines a rotation axis. A tapered drum that is wound with a purchase cable is mounted on the shaft for rotation about the axis. The drum and the shaft are rotated during the pay out of cable from the drum as the moving object engages and then pulls on the cable. The arresting gear includes an energy-dissipating fluid turbine, such as a water twister, that is mounted on the shaft to apply a torque on the shaft that acts to decelerate the rotating shaft. To complement the energy-dissipating fluid turbine, an electric motor is coupled to the shaft for creating a decelerating torque on the shaft. An electric motor control system is configured to use motor rotation feedback from the electric motor to pay out the cable from the drum at a substantially constant tension.
A system for controlling the pay out tension of a line used to decelerate a moving object, said system comprising:
