Cargo Lift System.
DEPARTMENT OF THE NAVY WASHINGTON DC
Pagination or Media Count:
A system for transferring cargo at sea by helicopter includes an automatically activated self inflatable apparatus for reducing the velocity of the cargo if jettisoned or inadvertently dropped into the sea and for keeping the cargo afloat until retrieval may be accomplished. The cargo is lifted by a support sling attachable to a helicopter suspension cargo hook and simultaneously connected to a second sling in parallel to the helicopter through the rapidly deployable retardation and floatation device. Release of the support sling causes the cargo to drop and initiate deployment and inflation of the ribs of the parachute thereby retarding the cargos descend and providing buoyancy for its floatation.
