Evaluation of an Alternative Rotorcraft Cargo Lowering Device for the Delivery of 500-lb Ammunition Loads.

摘要

The focus of this analysis was to investigate a commercial lowering device called the Sky Genie for rotorcraft delivery of 500-lb ammunition loads. This item, similar to the presently used cargo and personnel rappelling device, uses the friction of rope on metal to control the payload's descent. Reduction in payload descent time, which translates into improved troop and aircraft survivability, was sought. This report describes the functional and operational tests performed on this item. Based on these tests, it was concluded that the Sky Genie represents an effective, predictable means of delivering up to 500-lb payloads from altitudes up to 100 ft with no user input once the load leaves the rotorcraft.
