Abstract:
The present invention relates to unattended ground sensors for detecting the presence of a pedestrian or vehicle in a monitored area using seismic sensors. Networks of simple and inexpensive sensors are disclosed that may be rapidly deployed from the air. Each ground sensor is provided with a rotor that slows the rate of descent of the ground sensor during deployment.
Abstract:
An air-launched aircraft (10) includes deployable wings (16, 18), elevons (20, 22), and vertical fins (26, 28) that deploy from a fuselage (12) during flight. The aircraft may include a control system for operating the elevons, a communication system, and batteries for powering the systems. In addition, the aircraft may include a payload module (14) that mates with an interface in the fuselage. The payload module may include any of a variety of payloads, including cameras, sensors, and/or radar emitters. The aircraft may be powered or unpowered, and may be very small, for example, less than on the order of 10 kg (22 pounds). The deployable surfaces of the aircraft may be configured to deploy in a pre-determined order, allowing the aircraft automatically to enter controlled flight after being launched in a tumbling mode.
Abstract:
Methods and apparatuses for launching unmanned aircraft and other flight devices or projectiles are described. In one embodiment, the aircraft (150) can be launched from an apparatus that includes a launch carriage (120) that moves along a launch axis. A gripper (180) carried by the launch carriage can have at least one grip Portion (181) in contact with the aircraft while the launch carriage accelerates along the launch axis. The at least one grip portion can move out of contact with the fuselage of the aircraft as the launch carriage (120) decelerates, releasing the aircraft (150) for takeoff.
a supporting structure (2) including a central rotational support (3) having a vertical axis connected to an essentially horizontal, preferably annular, peripheral support part (4), coaxial with the central support (3), at least one upper rotor (6) including a central hub (7) rotatable about the axis of the central support (3) of the supporting structure (2), an outer channel-section ring (8) supported by the peripheral part (4) of the supporting structure (2) by contactless suspension means (23-27), preferably magnetic suspension means, and a plurality of blades (9) which extend from the hub (7) to the channel-section ring (8) and which are inclined with respect to the horizontal plane; and motor devices (40-43; 50-53) carried at least partially by the peripheral part (4) of the supporting structure (2) and operable to cause rotation of the rotor (6) with respect to this structure (2) in a predetermined direction.
Abstract:
VTOL micro-aircraft comprising a first and a second ducted rotor (1, 2) mutually aligned and distanced according to a common axis and whose propellers (4, 6) are driven in rotation in mutually opposite directions. Between the two ducted rotors (1, 2) are positioned a fuselage (3) and a wing system (13) formed by wing profiles (10, 11) forming an X or an H configuration and provided with control flaps (16).
