External load mass rope of a rotorcraft
First Claim
1. An external load mass rope for attachment to a cargo hook device of a rotorcraft that comprises at least one first cargo hook and at least one second cargo hook, the external load mass rope comprising at least one first rope leg and at least one second rope leg, wherein the at least one first rope leg is configured for attachment to the at least one first cargo hook and the at least one second rope leg is configured for attachment to the at least one second cargo hook, wherein at least one third rope leg is connected to the at least one first rope leg and the at least one second rope leg such that the at least one first, second and third rope legs define a Y-rope, the at least one third rope leg comprising an external load mass interface for attachment to an external load mass that is to be carried by the rotorcraft in operation, wherein the first rope leg comprises a first length adjustment unit in-line with the first rope leg and that is adapted to shorten or lengthen the first rope leg in flight operation of the rotorcraft on the basis of associated operating parameters, and wherein the second rope leg comprises a second length adjustment unit in-line with the second rope leg and that is adapted to shorten or lengthen the second rope leg in flight operation of the rotorcraft on the basis of the associated operating parameters, the first and second length adjustment units defining a length adjustment device;
- wherein the external load mass is deflected in forward flight direction or backward flight direction of the rotorcraft in operation by an associated external load mass deflection angle; and
wherein the cargo hook device is configured as a double cargo hook arrangement defining a forward cargo hook attachment point and an aft cargo hook attachment point, the first rope leg of the external load mass rope being a forward leg configured for attachment to the forward cargo hook attachment point using the at least one first cargo hook and with the first length adjustment unit being adapted to shorten or lengthen the forward rope leg in flight operation, the second rope leg of the external load mass rope being an aft leg configured for attachment to the aft cargo hook attachment point using the at least one second cargo hook and with the second length adjustment unit being adapted to shorten or lengthen the aft rope leg in flight operation.
