Disclosed is a package delivery mechanism (PDM) of an unmanned aerial vehicle (UAV). The PDM includes a gravity activated locking mechanism to lock and unlock a package attached to the UAV based on the weight of the package. When the package is attached to suspension means of the UAV that lowers the package to the ground from the UAV, the locking mechanism automatically engages with the package and keeps the package locked to the suspension means, due to the weight of the package. When the package is lowered and reaches on the ground, the weight of the package is offloaded from the suspension means, which enables the locking mechanism to be disengaged, thereby releasing the package. The PDM includes a severing module to sever the suspension means from the UAV.

An aircraft, the aircraft including a whole-aircraft ballistic parachute that is coupled to the aircraft. The aircraft determines if a pre-activation action needs to be performed before activation of the whole-aircraft ballistic parachute. The aircraft also receives a whole-aircraft ballistic parachute activation request. The aircraft then issues a command to perform the pre-activation action and then activates the deployment of the whole-aircraft ballistic parachute. The aircraft then issues a command to perform a post-activation action.

A thermally insulated package 100 for transporting a temperature sensitive payload by unmanned aerial vehicle. The thermally insulated package comprises a payload retention volume 150, at least one layer of insulation 121, 122 surrounding the payload retention volume 150 and an outer casing 110 enclosing the at least one layer of insulation 121, 122 and the payload retention volume 150. The thermally insulated package 100 is shaped to reduce drag in flight by having an aerodynamic shape, particularly in a nose section 130 and optionally a tail section 140. The thermally insulated package 100 may be particularly suitable as a single use packaging for transporting temperature sensitive goods to remote locations. A packaging blank 200 and an unmanned aerial vehicle comprising the thermally insulated package 100 are also disclosed.

A parachute riser assembly for a parachute comprises a left riser, a right riser, and a curtain. The left riser is configured to extend from a canopy and is configured to be coupled to a left attachment point of a harness worn by a user, according to various embodiments. Similarly, the right riser is configured to extend from the canopy and is configured to be coupled to a right attachment point of the harness, according to various embodiments. The curtain may be coupled to and may extend between the left riser and the right riser. In various embodiments, a portion of the curtain is configured to move along the left riser and the right riser from a furled state to an unfurled state in response to tensioning the left riser and the right riser.
