  • Air-driven, turbine tow reel machine controlled according to towline velocity and vent door position
    Patent number: 5083723
    Abstract: A reeling control system and an air driven tow reel machine incorporating such a control system are disclosed. In the disclosed control system and reeling machine of the present invention, towline velocity is monitored and reel-in and reel-out operations are regulated according to a programmed towline velocity profile. A position sensor senses the position of the turbine vent doors and a velocity sensor device provides the instantaneous towline velocity. A velocity comparator compares the instantaneous towline velocity with a desired velocity value from a desired velocity profile. Based upon the difference between actual and desired towline velocities, a door control device generates a driving signal for controlling the vent door position accordingly.
