Patent number: 11837102Abstract: An aircraft defining an upright orientation and an inverted orientation, a ground station; and a control system for remotely controlling the flight of the aircraft. The ground station has an auto-land function that causes the aircraft to invert, stall, and controllably land in the inverted orientation to protect a payload and a rudder extending down from the aircraft. In the upright orientation, the ground station depicts the view from a first aircraft camera. When switching to the inverted orientation: (1) the ground station depicts the view from a second aircraft camera, (2) the aircraft switches the colors of red and green wing lights, extends the ailerons to act as inverted flaps, and (3) the control system adapts a ground station controller for the inverted orientation. The aircraft landing gear is an expanded polypropylene pad located above the wing when the aircraft is in the upright orientation.Type: GrantFiled: October 19, 2020Date of Patent: December 5, 2023Assignee: AeroVironment, Inc.Inventors: Christopher E. Fisher, Thomas Robert Szarek, Justin B. McAllister, Pavel Belik

Patent number: 11775916Abstract: 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 package. For example, an aerial vehicle may be an airplane or helicopter that remains at altitude with a packaged stowed for deployment. As the mothership travels in the vicinity of the designated location the 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 package disengages the mothership. As the 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.Type: GrantFiled: April 1, 2021Date of Patent: October 3, 2023Assignee: AeroVironment, Inc.Inventors: Joel Nathan Ifill, Joseph R.
