    摘要: Physical and logical components of a long line loiter control system address control of a long line loiter maneuver conducted beneath a carrier, such as a fixed-wing aircraft. Control may comprise identifying, predicting, and reacting to estimated states and predicted states of the carrier, a suspended load control system, and a long line. Identifying, predicting, and reacting to estimated states and predicted states may comprise determining characteristics of state conditions over time as well as response time between state conditions. Reacting may comprise controlling a hoist of the carrier, controlling thrusters of the suspended load control system, and or controlling or issuing flight control instructions to the carrier so as not to increase the response time and or to avoid a hazard.

    摘要: Disclosed are systems, apparatuses, and methods to deploy and stow a deployable equipment to and from a hoist, to control a load on a suspension without transfer of torque to the suspension cable, for the deployable equipment to obtain data and information from the hoist, and for the deployable equipment to control the hoist, such as a reel of a hoist, to control a z-axis of a terminal end of the suspension cable. Control of the z-axis may be, for example, to control an elevation of a load, such as relative to carrier, ground, or an objective or target, to control a tension on or of suspension cable. Control of the z-axis may be, for example, to control a rate of ascent or descent of a terminal end of suspension cable.

    摘要: A bidirectional thrust assembly comprises a motor, a selective power transfer mechanism, and a plurality of fans; wherein a change in direction of rotation of the motor causes the selective power transfer mechanism to change a torque transfer among the plurality of fans, wherein the fans may be opposing, and wherein the fans may be unidirectional. The bidirectional thrust assembly may be used in or by a plurality of craft or with respect to other objects which may need to be maneuvered, included suspended load control systems, vertical takeoff and landing craft, watercraft.
