Systems, apparatuses, and methods are provided herein for stabilizing an unmanned aerial system. An apparatus for stabilizing an unmanned aerial system comprises a ring member and a pair of attachment members each having a first end and a second end, the first end being configured to attach to a multicopter and a second end being coupled to the ring member. Wherein the pair of attachment members holds the ring member such that a plane of a circumference of the ring member is generally parallel to blades of the multicopter.

The invention relates to a flight unit for a vertical take-off and landing aircraft with a plurality of drive units arranged on a wing assembly, wherein the wing assembly comprises longitudinally extended wing assembly struts connected to one another at node points. According to the invention, a certain number of the wing assembly struts each comprise at least one wing with aerofoil form, which wing is arranged or configured for rotation in a longitudinal section of the wing assembly strut which extends longitudinally between two nodes.

A system and method are disclosed and may be used for controlling (e.g., stabilizing) a suspended load. The system may include a hoist, an imaging sensor configured to capture images of a swinging of a load suspended from the hoist, and a controller. The controller may include one or more processors configured to execute a set of program instructions stored in a memory. The program instructions may be configured to cause the one or more processors to receive the images, determine positions of the load over time based on the images, calculate swing data of the swinging of the load based on the positions, determine flight control commands based on the swing data, and direct a flight control system configured to adjust a flight of an aircraft based on the flight control commands.
