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.

A ground state determination system for an aircraft includes sensors configured to detect parameters of the aircraft and a flight control system implementing a ground state module. The ground state module includes a ground state monitoring module configured to monitor the parameters and a ground state determination module configured to compare each of the parameters monitored by the ground state monitoring module to a respective parameter threshold to determine whether the aircraft is on a surface.

Provided is a flight device that includes multiple drive sources and that can continuously fly even when one of the drive sources stops in flight, by using the other drive source. The flight device 10 includes a first drive system 11 and a second drive system 12. The first drive system 11 includes a battery 27, rotor 151 and the like configured to be rotated by energy supplied from the battery 27, and a first control unit 20 configured to control the numbers of revolutions of the rotor 151 and the like depending on a flight condition. The second drive system includes the battery 27, rotor 181 and the like configured to be rotated by energy supplied from the battery 27, and a second control unit 21 configured to control the numbers of revolutions of the rotor 181 and the like depending on the flight condition. In the emergency flight state, when the first drive system 11 stops, the flight device 10 lands by rotating the rotor 151 and the like, and when the second drive system 12 stops, the flight device 10 lands by rotating the rotor 181 and the like.

The present invention relates to a system and a method for mobile landing of an unmanned vehicle. The method includes: detecting a landing target pattern by a three-dimensional sensing module and transmitting the landing target pattern to a calculation module, the landing target being a moving object; calculating, by the calculation module, a relative correction parameter of a guiding coordinate position of a return side relative to a coordinate position of the unmanned vehicle according to the landing target pattern and the guiding coordinate position of the return side; correcting, by the calculation module, the guiding coordinate position of the return side according to the relative correction parameter to obtain a corrected guiding coordinate position; then calculating, by the calculation module, a deviation value between the corrected guiding coordinate position and the coordinate position of the unmanned vehicle, and transmitting the deviation value to the vehicle side control module, and controlling, by the vehicle side control module, the unmanned vehicle to arrive at the return side according to the deviation value. The present invention thereby achieves a precise dynamic target landing.

Systems, apparatuses and methods for landing an unmanned aircraft on a mobile structure are presented. Sensors on the aircraft identify a predetermined landing area on a mobile structure. The aircraft monitors the sensor data to maintain its position hovering over the landing area. The aircraft estimates a future attitude of the surface of the landing area and determines a landing time that corresponds to a desired attitude of the surface of the landing area. The unmanned aircraft executes a landing maneuver to bring the aircraft into contact with the surface of the landing area at the determined landing time.
