摘要： A self-release mechanism. The self-release mechanism includes a counter-weight, wherein the counter-weight is located on a first end of the self-release mechanism; a shaft having a top portion and a bottom portion, wherein the top portion of the shaft is coupled to the counter-weight, wherein the shaft defines a perforation, wherein the perforation is adapted to receive a cord; and a hook including a hook bend, wherein the hook is located on a second end of the self-release mechanism, wherein the hook is coupled to the bottom portion of the shaft, wherein the self-release mechanism moves to a first position when a tension is exerted on the self-release mechanism due to gravity caused by coupling of the hook to a payload via the hook bend, wherein the self-release mechanism moves to a second position when the exerted tension is released.

摘要： A load placement system precisely places slung loads by allowing a helicopter pilot to essentially reel the load to the ground. The placement system uses lead lines on the slung load that can be connected to the ground by support personnel. A winch system is connected to the lead lines and guides the load to an intended location. The placement system eliminates at least some of the ground personnel previously needed for pulling the load to a target location and orientation. The placement system may eliminate substantially all ground personnel by using unmanned aerial vehicles (UAVs) to automatically connect the lead lines to the ground. The UAVs also may actively control the slung load while in flight to reduce pilot workload and enable higher transport speeds.

摘要： A belly bar method and apparatus use to attach, carry and release external cargo from a hovering aircraft. The belly bar apparatus has articulated tubing tool connected to an airframe of the hovering aircraft at a first mounting end and at a second mounting end. The articulated tubing tool has a first external catch and a second external catch mounted on the articulated tubing tool. The first external catch is manually configured for optional attach, carry and release of the external cargo via the cyclic. The second external catch is electronically configured for optional attach, carry and release of the external cargo proximate the collective.

摘要： An example system includes an aerial vehicle, a sensor, and a winch system. The winch system includes a tether disposed on a spool, a motor operable to apply a torque to the tether, and a payload coupling apparatus coupled to the tether and configured to mechanically couple to a payload. The system also includes a repositioning apparatus configured to reposition the payload coupling apparatus in at least a horizontal direction. A control system is configured to control the aerial vehicle to deploy the payload coupling apparatus by unwinding the tether from the spool; receive, while the aerial vehicle hovers above the payload and from the sensor, data indicative of a position of the payload coupling apparatus in relation to the payload; and reposition, using the repositioning apparatus and based on the data, the payload coupling apparatus in the horizontal direction to mechanically couple to the payload.

摘要： A quadrotor or other vertical lift aerial vehicle measures an angle of a payload slung from the quadrotor relative to a body of the quadrotor. Using this measurement a signal may be generated that adjusts a flight characteristic of the quadrotor to counteract swing in the payload. A feedback function for generating the feedback signal may include proportional and derivative gain functions as well as non-linear signal processing functions. The feedback signal may be added to normal input control signals to cause acceleration in the direction of the payload angle that damp oscillation of the slung payload caused by wind or movements of the quadrotor.
