System and method for payload transportation
The invention(s) include embodiments and applications of: a system for package handling, the system including: an aerial vehicle and a conveying subsystem configured to interface with the aerial vehicle. The system can execute operation modes, associated with loading and unloading of multiple packages, and delivering one or more packages to receiving sites.
1 . A system comprising:
an aerial vehicle comprising:
a fuselage;
a storage region positioned longitudinally within the fuselage, the storage region configured for receiving and transporting a payload;
a forward wing mounted to the fuselage;
an aft wing mounted to the fuselage, wherein the forward wing and aft wing are configured to accommodate at least a 20% deviation in center of gravity associated with a payload of the aerial vehicle;
an array of powered lift devices, each powered lift device of the array of powered lift devices coupled to the fuselage between the forward wing and the aft wing;
a forward thrust generating device;
an integral subsystem comprising a set of weight sensing devices that measure and report vertical ground reaction forces acting on the aerial vehicle, wherein a housing of the integral subsystem is designed such that application of non-vertical loads to the aerial vehicle does not interfere with accurate measurement of said vertical ground reaction forces, and wherein the set of weight sensing devices report signals informative of innately redundant and flight critical binary loaded or unloaded statuses of the aerial vehicle; and
a conveying subsystem configured to autonomously transfer the payload to and from the storage region, to autonomously position the payload to satisfy a weight and balance criterion, and to autonomously secure the payload in preparation for and to increase safety of flight of the aerial vehicle.
2 . The system of claim 1 , where the array of powered lift devices, the forward wing, and the aft wing are positioned to prevent wakes from the array of powered lift devices and forward wing from impinging on any other component of the aerial vehicle during a hovering operation mode, a forward flight operation mode, and during transitions between the hovering operation mode and the forward flight operation mode.
3 . The system of claim 2 , wherein the forward wing comprises landing elements coupled to wing tips of the forward wing, with the forward wing acting to attenuate landing gear loads.
4 . The system of claim 3 , wherein powered lift devices of the array of powered lift devices are configured with dihedral to provide roll stability during vertical flight phases of the aerial vehicle.
5 . The system of claim 4 , wherein the forward wing comprises an anhedral angle and wherein the aft wing comprises a dihedral angle and wherein a dihedral angle of the aft wing is configured to counteract an anhedral angle of the forward wing, in order to provide lateral and directional stability, and enhance spin recovery of the aerial vehicle.
6 . The system of claim 5 , further comprising upward sloping winglets positioned at outboard tips of the forward wing, said upward sloping winglets configured to prevent wing tip dig in during landing of the aerial vehicle, and said upward sloping winglets configured to decrease aerodynamic drag during forward flight of the aerial vehicle.
