A parafoil for operation at high altitudes, in low density air, or at low airspeeds, and methods for opening same. Some versions of the parafoil comprise flexible members connected to the parafoil canopy. When the parafoil canopy is in a stowed configuration, the members are deformed, storing elastic energy. When the canopy is released from its stowed configuration, the members spring back to their undeformed shapes, thereby opening or assisting with opening the canopy. The flexible member may also be attached to a base structure, which is attached to the payload. The members may comprise rods or hollow tubes that can be flexed using a fulcrum near the base structure, or a spacer plate, so that the ends connected to the canopy are restrained by a parachute bag containing the stowed or packed canopy. The parachute bag can be opened prior to or during detachment of the parafoil from the flight vehicle.

Cargo aerial delivery systems for delivering one or more delivery items and related methods. A cargo aerial delivery system may include a cargo container configured to carry the delivery item(s) and an unmanned aerial vehicle (UAV) configured to carry the cargo container to delivery destinations of the delivery items. The cargo container may include a programmable device that stores manifest information regarding the delivery item(s) and a local communication mode configured to convey delivery information from the cargo container to the UAV. A method of utilizing a cargo aerial delivery system may include loading delivery item(s) into a container body of a cargo container, entering manifest information into a programmable device, operatively engaging the cargo container with a UAV, generating a delivery itinerary, transporting the cargo container with the UAV according to the delivery itinerary, and unloading each delivery item at the respective delivery destination.

The present disclosure relates to an aerial vehicle for carrying a load. The aerial vehicle comprises an environmental monitoring system configured to monitor the environment of the aerial vehicle and a data processing circuitry. The data processing circuitry is configured to determine, based on the monitored environment, a risk to the environment posed by at least one of the aerial vehicle and the load of the aerial vehicle in case of a crash of the aerial vehicle. The data processing circuitry is further configured to cause, based on the determined risk, the aerial vehicle to carry out an action in order to reduce a damage to the environment in case of the crash.

An unmanned aerial vehicle includes: a vehicle main body having a first length in a first direction longer than a second length in a second direction orthogonal to the first direction; propellers that rotate in a virtual plane parallel to the first and second directions; first propeller actuation motors that are provided on the vehicle main body and respectively rotate the propellers; at least one connector that is hangable from at least one rail spaced apart from the ground surface; at least one side propeller that provides propulsion force for propelling the vehicle main body in the first direction; at least one third propeller actuation motor that is provided on the vehicle main body and rotates the at least one side propeller; and a control processor that controls the first propeller actuation motors and the at least one third propeller actuation motor.

An unmanned aerial vehicle (UAV) can deliver a package to a delivery destination. Packages delivered by a UAV may be lowered towards the ground while the UAV continues to fly rather than the UAV landing on the ground and releasing the package. Packages may sway during lowering as a result of wind or movement of the UAV. By modulating a rate of descent of a package, a package sway may mitigated. The lowering mechanism includes wrapping a tether in various directions around the package such that the package rotates in a first and second direction as the package descends. Additionally, a rip-strip lowering mechanism that separates under tension to lower the package and a rappel mechanism that slides the package down a tether may be used. Accordingly, the tether can control a descent of the package assembly.
