  • Patent number: 5499785
    Abstract: A method and apparatus for automatically jettisoning cargo carried by a dual-point suspension system when a suspension system failure is detected. Three conditions must be satisfied before a load is jettisoned. The average value of the load and an instantaneous value of the load on a hook must have fallen below a threshold value (zero load condition). A threshold amount of the load must have shifted from one hook to the other (dynamic load split condition). A threshold amount of an initial hook load must have been lost within a short period of time (rapid rate-of-decrease condition). For all three conditions, the threshold amount or value is adaptively set based on the actual load carried by the dual-point suspension. If all three conditions are satisfied for either the forward or the aft hook, the cargo is jettisoned. Additionally, a fourth condition that detects whether a structural limit of a hook has been exceeded is evaluated. If the structural limit has been exceeded, the load is jettisoned.
