Abstract:
A span-loaded, highly flexible flying wing, having horizontal control surfaces mounted aft of the wing on extended beams to form local pitch-control devices. Each of five spanwise wing segments of the wing has one or more motors and photovoltaic arrays, and produces its own lift independent of the other wing segments, to minimize inter-segment loads. Wing dihedral is controlled by separately controlling the local pitch-control devices consisting of a control surface on a boom, such that inboard and outboard wing segment pitch changes relative to each other, and thus relative inboard and outboard lift is varied.
Abstract:
Systems and associated methods for planning and control of a fleet of unmanned vehicles in missions that are coordinated temporally and spatially by geo-location, direction, vehicle orientation, altitude above sea level, and depth below sea level. The unmanned vehicles' transit routes may be fully autonomous, semi-autonomous, or under direct operator control using off board control systems. Means are provided for intervention and transit changes during mission execution. Means are provided to collect, centralize and analyze mission data collected on the set of participating unmanned vehicles.
Abstract:
A rotorcraft including a fuselage, one or more motor-driven rotors for vertical flight, and a control system. The motors drive the one or more rotors in either of two directions of rotation to provide for flight in either an upright or an inverted orientation. An orientation sensor is used to control the primary direction of thrust, and operational instructions and gathered information are automatically adapted based on the orientation of the fuselage with respect to gravity. The rotors are configured with blades that invert to conform to the direction of rotation.
Abstract:
An aircraft system incorporates a first aircraft having a grappling device including a first gripper with a first actuator and a second gripper with a second actuator. The first gripper and the second gripper are movable between an open and a closed position to engage a hooking device and pivot together to change a capture angle. A first controller receives a command and operates the actuators in response to open and close the first and second grippers of the grappling device. The controller also receives a second command and operates the first and second actuators to pivot the grippers and provide grappling at a range of capture angles. A second aircraft, which may be a UAV, incorporates the hooking device. The hooking device includes a ring rotatable from the surface and a third actuator to rotate the ring between a stowed and an extended position.
Abstract:
A system of software and hardware components is disclosed comprising a system designed to deploy, manage, and control unmanned aerial vehicles (UAVs). The integrated UAVs can be deployed from vehicles, buildings, and other types of fixed locations. The present disclosure enables users to deploy UAVs to perform pre-defined flight maneuvers and fly to pre-designated locations. The present disclosure also and affords the ability for users to maintain the UAVs flight control locally or transfer control of a deployed UAV to remotely located system operators.
Abstract:
A vehicle which is adaptable for both flight and water travel includes: a body; a wing, a stabilizer, or a first propelling member; and at least one attachment member. The body is configured to fly through air and to move through water. The at least one attachment member attaches the wing, the stabilizer, or the first propelling member to the body while the body is in flight. The at least one attachment member detaches at least a portion of the wing, at least a portion of the stabilizer, or at least a portion of the first propelling member from the body when the body is in the water.
Abstract:
A combination rotor and wheel assembly for an unmanned vehicle with ground and aerial mobility has a rotor arm adapted to be attached at an inner end thereof to a vehicle body. A rotor is rotatably connected to an outer end of the rotor arm about a rotor axis, and a rotor drive mounted on the rotor arm rotates the rotor such that the rotor exerts an upward lift force on the rotor arm. An open spoked wheel is rotatably connected about the rotor axis independent of the rotor The diameter of the wheel is greater than that of the rotor, and a bottom edge of the wheel is below the rotor. A wheel drive rotates the wheel. Vehicles can have various numbers and orientations of the rotor and wheel assembly to provide aerial and ground mobility.
Abstract:
The present invention relates to a helicopter having a modular airframe, with multiple layers which can be connected easily, the layers which house the electronics (autopilot and navigation systems), batteries, and payload (including camera system) of the helicopter. The helicopter has four, six, and eight rotors, which can be easily changed via removing one module of the airframe. In one embodiment, the airframe has a vertical stacked appearance, and in another embodiment, a domed shape (where several of the layers are stacked internally). In one embodiment, there is a combination landing gear and camera mount. The helicopter allows for simple flight and usage by remote control, and non-remote control, users.

Abstract:
A pod for an unmanned aerial vehicle is provided that may be removed and re-attached to the vehicle. The pod comprises an outer shell, within which a variety of payloads may be carried. A first surface on the vehicle frame comprises a plurality of connects or electrical traces. The plurality of attachments are used to removably attach the pods to the first surface. Thus, a wide variety of payloads may be delivered using the same unmanned aerial vehicle, simply by removing and attaching different pods to a fixed vehicle core. These pods may be shaped so as to form part of the vehicle exterior, and when the pods are attached to the frame, they enhance the aerodynamics of the vehicle.
