The present technology is directed to a remotely controlled aircraft that can be transported without the risk of damaging certain components, such as the arms and/or propellers. In one non-limiting example, the remotely controlled aircraft technology described herein provides a housing that allows the arms of the remotely controlled aircraft to extend and/or retract through openings in the housing. When retracted, the arms and propellers are protected within an area of the structure of the housing, and when extended, the arms and propellers are operable to make the remotely controlled aircraft fly.

A landing pad for an unmanned aerial vehicle (“UAV”) is disclosed. The landing pad includes a support structure, a charging pad, and a plurality of movable UAV supports. The charging pad is coupled to the support structure and able to move relative to the support structure. The UAV supports are also coupled to the support structure and configured to translate along the support structure from a first position to a second position. When the UAV supports are in the first position, the charging pad supports the UAV. When the UAV supports are in the second position, the charging pad is lowered and the UAV supports then provide support to the UAV.

An unmanned aerial vehicle (UAV) system for maintaining UAV flight continuity, includes a ground station, a first UAV, a second UAV, a processor, and a memory. The memory contains instructions thereon, which, when executed by the processor in response to receiving a remaining battery charge signal from the first UAV, selectively deploy the second UAV from the ground station when the remaining battery charge signal indicates that a remaining battery charge of the first UAV is below a threshold value, and return the first UAV to the ground station.

A rotorcraft-assisted system for launching and retrieving a fixed-wing aircraft into and from free flight. The launch and retrieval system is usable with a rotorcraft to launch a fixed-wing aircraft into free, wing-borne flight and to retrieve the fixed-wing aircraft from free, wing-borne flight.

Various systems, methods, for unmanned aerial vehicles (UAV) are disclosed. In one aspect, UAVs operation in an area may be managed and organized by UAV corridors, which can be defined ways for the operation and movement of UAVs. UAV corridors may be supported by infrastructures and/or systems supported UAVs operations. Support infrastructures may include support systems such as resupply stations and landing pads. Support systems may include communication UAVs and/or stations for providing communications and/or other services, such as aerial traffic services, to UAV with limited communication capabilities. Further support systems may include flight management services for guiding UAVs with limited navigation capabilities as well as tracking and/or supporting unknown or malfunctioning UAVs.

A method and apparatus for an unmanned aerial system is described herein. An unmanned aerial system capable of being launched from a grenade launcher includes a tubular body that encloses a compartment for a payload and a battery, a motor coupled to the tubular body, a propeller coupled to the motor, and a parachute disposed within the tubular body when the unmanned aerial system is in a stowed configuration and disposed outside of the tubular body when the unmanned aerial system is in a powered flight configuration.

An unmanned aerial vehicle (UAV) system operates with a flight management system and has controlled access UAV zones, each being UAV landing, loading, takeoff. A control and communication unit controls access to each UAV zone. A barrier around each zone controls entry into that zone. An opening in the barrier permits personnel to enter. A closure for the opening is locked by at least one remotely operable lock. A communications module is operable to control the lock for that zone to govern access to and entry into that zone by users. A flight management system is separate from the plurality of zones and in communication with the control and communication unit and with each communications module, and responsive to requests by users to allow access. At least some of the UAV zones are charging zones that include at least one charging cable for charging a battery of a UAV.

A propulsion system assembly includes a propeller, a motor configured to drive the propeller to rotate, and a locking mechanism configured to detachably lock the propeller to the motor. The propeller includes one of a first body and a second body. The motor includes another one of the first body and the second body. The locking mechanism includes a coupling member including a femoral position groove, a fastener configured to fix the coupling member to the second body, and a locking member configured to lock the first body to the coupling member and the second body. A bottom portion of the first body that contacts the coupling member includes a protruding rib configured to fit with the femoral position groove to restrain the first body from rotating relative to the coupling member.

The rotary wing drone comprises at least one rotor carried by a drone structure, wherein the drone structure comprises a drone body and at least one group of arms comprising a plurality of arms rotatably mounted on the drone body about the same axis of rotation, between a deployed position for flight and a folded position for transport.

An unmanned aerial vehicle is provided. The unmanned aerial vehicle includes a housing with a first housing structure and a second housing structure, a wireless communication circuit coupled to the housing or located inside the housing for wireless communication with an external controller, a plurality of propulsions systems coupled to the housing, and a navigation circuit configured to control the plurality of propulsion systems. At least one of the plurality of propulsion systems includes a plurality of folding arms pivotally coupled to one of the first housing structure and the second housing structure, a motor controlled by the navigation circuit, and a propeller coupled to the motor. The housing has at least one recess to accommodate at least part of the plurality of propulsion systems in the second state.
