Abstract : A program to design, fabricate, and test a fluidically controlled cargo hook for a CH-54 type helicopter was conducted. The existing cargo system uses an electrically controlled cargo hook which is attached to a 100-foot length of cable wound on a hoist drum. The existing hoist system was modified to permit a prototype pneumatic/fluidic system to be used in place of the electrical system. The system was tested and, though only 559 of the proposed 1000 cycles of testing were successfully completed, the concept proved to be feasible. It is recommended that further testing be conducted after the incorporation of relatively minor improvements shown to be necessary during the 559 cycle testing.
