Hoist Stabilization Design Method
摘要
Helicopter payloads for aerial evacuation (MEDEVAC) rescues are difficult to stabilize once the patient begins to swing. As a result of oscillation forces during lifting, the payload begins to swing in three dimensions under the helicopter. Swinging can pose a threat to both the crew in the helicopter and the patient attached to the cable. We first demonstrate that a payload can be stabilized in two dimensions, before exploring a three-dimensional solution. We assume that the helicopter is in a “steady hover” over the patient [1].
