Abstract:
UAV configurations and battery augmentation for UAV internal combustion engines, and associated systems and methods are disclosed. A representative configuration includes a fuselage, first and second wings coupled to and pivotable relative to the fuselage, and a plurality of lift rotors carried by the fuselage. A representative battery augmentation arrangement includes a DC-powered motor, an electronic speed controller, and a genset subsystem coupled to the electronic speed controller. The genset subsystem can include a battery set, an alternator, and a motor-gen controller having a phase control circuit configurable to rectify multiphase AC output from the alternator to produce rectified DC feed to the DC-powered motor. The motor-gen controller is configurable to draw DC power from the battery set to produce the rectified DC feed.
Abstract:
VERTICAL TAKE OFF AND LANDING CLOSED WING AIRCRAFT An aircraft (100) capable of vertical takeoff and landing, stationary flight and forward flight includes a closed wing (102) that provides lift whenever the aircraft (100) is in forward flight, a fuselage (104) at least partially disposed within a perimeter of the closed wing (102), and one or more spokes (106) coupling the closed wing (102) to the fuselage (104). The fuselage (104) can have a rear module substantially disposed within a perimeter of the distributed airframe (1002, Figure 11), and a front module removably connected to the rear module and substantially aligned with the longitudinal axis. One or more engines or motors (132) are disposed within or attached to the closed wing (102), fuselage (104) or spokes (106). Three or more propellers (120) are proximate to a leading edge of the closed wing (102) or the one or more spokes (106), distributed along the closed wing (102) or the one or more spokes (106), and operably connected to the one or more engines or motors (132). The propellers (120) provide lift whenever the aircraft (100) is in vertical takeoff and landing and stationary flight, and provide thrust whenever the aircraft (100) is in forward flight.
Abstract:
The device comprises at least one folding, inflatable chamber (3), at least one runner (4) for landing on water, which is coupled to the aircraft (2) by means of the chamber (3), and at least one air intake (6) connected to the chamber. The intake (6) allows the entry of incident air into the chamber (3) in order to inflate and deploy the chamber (3), extending the runner (4) from a retracted-runner position into an extended-runner position
Abstract:
A Micro Air-Vehicle (MAV) starting system that provides the combined functions of: packing protection of sensitive vehicle components, a mechanical starting assembly, and a launch pad. The preferred embodiment comprises a container (110) and a container lid (101) with the MAV (200) clamped to the lid. Also disposed on the container lid is a starting assembly (111). The lid (101) which doubles as a launching pad with the attached MAV (200) is removed from the container (110), placed on the ground, the MAV (200) is started with the starling mechanism and launched. The arrangement minimizes the physical risk to the operator, minimizes weight of the total MAV system, consumes minimum space in the operators transport system, and eliminates dependence on supply lines for battery replacement or charging.
Abstract:
Autonomous micro air vehicles (102) surveillance systems are provided. A MAV system of one embodiment includes an MAV and a launch pad (120). The MAV has an engine (103) that is adapted to power the MAV. The launch pad has a starter (128) that is adapted to start the engine in the MAV when the MAV is resting on a launching surface (142) of the launch pad. The launch pad further has a battery (126) to power the starter.
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.
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:
The invention describes a microaircraft (2), which can be associated for instance to a cellular phone (1), provided with at least four microrotors (4) actuated with compressed fluid or by ring-shaped electric motors (7).
Abstract:
An unmanned rotor carried aerial vehicle comprises a propulsion unit (5) and a carrier (7) suspended from the propulsion unit. The propulsion unit (5) is connected to the carrier (7) via a cardan-like joint (9) for permitting limited tilting of the propulsion unit relative to the carrier in two orthogonal directions corresponding to the roll and pitch directions of the vehicle and for preventing relative movement between the propulsion unit and the carrier in the yaw direction of the vehicle.
