Abstract:
An unmanned aerial vehicle (UAV) can be deployed from a small stowed package for flight and stowed back into the package after the flight is complete is disclosed. The UAV is retracted to a volume that is less than half of its fully deployed volume. This allows the UAV to be transported to any desired field position on a truck or other convenient transportation. The UAV may also be launched from a ship deck. In a further aspect, the flexible deployment of the UAV will allow a single UAV to be used in place of multiple types of UAVs.
Abstract:
The present invention relates to a system and method for automatic launch and landing UAVs (Unmanned Aerial Vehicles). The system comprises a ground station adapted for automatic UAV launching and landing. The ground station comprises: means for communication with UAVs present within a range from the ground station; an arrangement adapted for launching UAVs and for capturing in-flight UAVs, said arrangement having at least one controllable arm; a computing unit arranged to compute a meeting point between the at least one controllable arm and one in-flight UAV based on data communicated between the UAV and the ground station by means of said means for communication; and a control unit arranged to control the at least one arm to capture an in-flight UAV at the meeting point or to launch one UAV. The system is characterized in that the control unit is arranged to control the at least one arm to move a UAV between the meeting point and at least one storage position.
Abstract:
The present invention is an apparatus and system for providing surveillance of an area or a space. According to some embodiments of the present invention there may be provided a housing containing a deployable and inflatable surveillance balloon, which balloon may elevate and/or support a surveillance payload including one or more sensor assemblies. Data collected by the sensors may be transmitted to a user interface which may display the data to a user.
Abstract:
A rotary wing vehicle includes a body structure having an elongated tubular backbone or core and a counter-rotating coaxial rotor system having rotors. The rotor system is used to move the rotary wing vehicle in directional flight.
Abstract:
A dual ducted fan arrangement in which the duct components (203), engine (10), and avionics/payload pods (300, 302) are capable of being quickly disassembled to fit within common backpacking systems. Each duct is identical in fan (201 ), stator (102), and control vane design. Assembly connections between ducted fans (203) and electronic modules are also identical. An engine (10) or APU drives the dual ducted fans (203) through a splined shaft (601) to a differential (600) or through electric motors. Energy is transferred to the ducted fans by a single gear mounted to the stator (102) hub. Relative speeds of the individual ducted fans are controlled through separate frictional or generator load control braking mechanisms (603) on each of the splined shafts (601) between the differential (600) and ducted fans (203). In the electric motor case relative speed is through electronic speed control. The fans (201 ) are counter rotating for torque balancing. The electronic module locations are vertically variable for longitudinal center of gravity for variations in payloads.
Abstract:
A method for landing a fixed wing aircraft is provided in which an inversion maneuver is performed so that the aircraft's back is facing the ground, and the aircraft's underside is facing away from the ground. After initiation or completion of this maneuver, deep stall is induced, and the aircraft descends almost vertically to land on its upper side, thus minimizing impact loads or damage on its underside. In a particular aerodynamic arrangement configured for carrying out the method, a flap (24), which may be stowed during normal flight, is deployed in a manner such as to aerodynamically induce a negative pitching moment on the aircraft and deep stall.
Abstract:
Methods and apparatuses for assembling, launching, recovering, disassembling, capturing, and storing unmanned aircraft (140) and other flight devices or projectiles are described. In one embodiment, the aircraft (140) can be assembled from a container (111) with little or no manual engagement by an operator. The container (111) can include a guide structure to control motion of the aircraft components. The aircraft (140) can be launched from an apparatus that includes an extendable boom (103). The boom (103) can be extended to deploy a recovery line (853) to capture the aircraft (140) in flight. The aircraft (140) can then be returned to its launch platform, disassembled, and stored in the container (111), again with little or no direct manual contact between the operator and the aircraft (140).
Abstract:
A deployment or hinge mechanism and, more particularly, a compact unmanned aerial vehicle (UAV) wing deployment mechanism is provided. The deployment mechanism includes a hinged mechanism that stows in a stacked configuration and deploys in a level configuration.
Abstract:
A method of migrating unmanned aerial vehicle operations between geographic survey areas, including: uploading a first plurality of flight missions into a first UAV pod; deploying the UAV pod; autonomously launching the UAV and providing first survey data from the UAV to the UAV pod; autonomously migrating the UAV from the first UAV pod to a second UAV pod; receiving a second plurality of flight missions in a second UAV pod; providing the UAV with one of the second plurality of flight missions from the second UAV pod; autonomously launching the UAV and providing a second survey data from the UAV to the second UAV pod; where the autonomous migrating of the UAV to accomplish the first and second survey data happens autonomously and without active human intervention.
Abstract:
A method of unmanned aerial vehicle (UAV) operation, including: receiving from a customer a first data request (400), the first data request (400) having: a first geographic coverage area, and a refresh rate for the first geographic coverage area, planning a first plurality of flight missions to accomplish the first data request, uploading flight missions data representing the first plurality of flight missions into a UAV pod (404), and deploying the UAV pod (802).
