Criteria for Externally Suspended Helicopter Loads

Abstract

The study was conducted to determine the dynamic effects of a helicopter external load combination by simulating flight using a computer. Design criteria for sling members and hard points of the system were also established. A computerized hybrid simulation of the coupled motion of a CH-54 helicopter and selected external loads was conducted in real time with a pilot in the loop on both fixed-base and moving-base simulators. The results of the study indicate that the dynamic load factors produced in sling elements and at hard points during a maneuver often exceed the normal load factor developed by the helicopter. Data is included for the various loads and maneuvers.
