System and method for performing precision guided air to ground package delivery
Described is a method of delivery for cargo or goods from an aerial vehicle (mothership) to a designated ground delivery location via the use of a direct air shipping (DASH) package. For example an aerial vehicle may be an airplane or helicopter that remains at altitude with a DASH packaged stowed for deployment. As the mothership travels in the vicinity of the designated location the DASH package flight control computer (flight controller) calculates a preferred travel trajectory based upon the aerodynamic properties of the package and location relative to the designated delivery location such as a small delivery pad located on a patio of a home. When the mothership transits through a calculated release point the DASH package disengages the mothership. As the DASH package descends it may increase accuracy relative to the designated delivery location by altering aerodynamic properties to maintain the preferred travel trajectory and decreasing landing zone size requirements and increasing precision of delivery. To reduce the impact force at landing the designated delivery location and/or the DASH package may contain a net, airbag, parachute or similar device to provide a suitably soft landing suitable for commercial home delivery.
1. A device that delivers a payload to a ground location from an aerial vehicle, including:
a vehicle configured to enclose a payload;
a tail kit section releasably coupled to the vehicle and configured to be disposed on an upwardly oriented portion of the vehicle when the vehicle is in a flight path between the aerial vehicle and the ground location, wherein the tail kit section is configured to be recovered from the vehicle and releaseably coupled to a second vehicle;
a flight controller disposed in the tail kit section and configured to:
determine flight path adjustment parameters configured to actuate control surfaces on the device and to maintain the vehicle in the flight path to a designated landing site on the ground location, and
generate a trigger;
a nose section coupled to the vehicle and configured to be disposed on a downwardly oriented portion of the vehicle when the vehicle and the nose section are in the flight path between the aerial vehicle and the ground location, and
a parachute attached to the device and configured to be deployed by the trigger generated by the flight controller.

12. The system of claim 1 wherein:
the vehicle is configured to be discarded after a landing of the vehicle; and
the tail kit section is configured to be recoverable after the landing of the vehicle.
13. A method for delivering a payload from an aerial vehicle to a ground location, the method comprising:
storing a vehicle containing a payload to be delivered in the aerial vehicle, the vehicle having a tail kit section configured to be on top during a flight path of the vehicle from the aerial vehicle to the ground location, wherein the tail kit section is configured to be recovered from the vehicle and releaseably coupled to a second vehicle, a flight controller mounted in the tail kit section, and a nose section coupled to the vehicle;
programming a designated landing location into a memory onboard the aerial vehicle;
releasing the vehicle from the aerial vehicle;
deploying aerodynamic features on the vehicle;
controlling a direction of the vehicle while in flight; and
deploying a parachute based on a trigger at the flight controller, wherein the trigger is issued by the flight controller based on a received sensor value;
wherein the nose section is configured to be:
underneath the vehicle during the flight path of the vehicle from the aerial vehicle to the ground location; and
compressed upon a landing of the vehicle.
