Abstract:
A quadrotor UAV including ruggedized, integral-battery, load- bearing body, two arms on the load-bearing body, each arm having two rotors, a control module mounted on the load-bearing body, a payload module mounted on the control module, and skids configured as landing gear. The two arms are replaceable with arms having wheels for ground vehicle use, with arms having floats and props for water-surface use, and with arms having pitch-controlled props for underwater use. The control module is configured to operate as an unmanned aerial vehicle, an unmanned ground vehicle, an unmanned (water) surface vehicle, and an unmanned underwater vehicle, depending on the type of arms that are attached.
Abstract:
A flying toy suitable for being raised and then maintained in flight by the wind action, and controlled and maneuvered by means of an anchorage cable in a manner similar to that of a kite, that is provided with a birotor (1-6), and wherein the blades (1-4) of each rotor are partially flexible. The birotor is composed of two superimposed and coaxial rotors (1-6) and a synchronization mechanism (13) which obliges said rotors to effect symmetrical counter-rotations. Each blade (1-4) of each rotor comprises a substantially rigid proximal portion (1 ) whose cross section has the shape and the inclination incidence suggested by the laws of the aerodynamic, and comprises a distal portion (3) having a noticeable capability of undergoing flexional deformations. The flexible distal portion (3) may have a cross section identical or similar to the cross section of the rigid proximal portion (1 ), or a cross section simplified with respect to the rigid proximal portion (1). The flexible distal portion (3) may form an extension of the rigid proximal portion (1 ) or be pivoted to the rigid proximal portion (1 ) around an axis (4) at least approximately parallel to the rotor axis, whereby the distal portion (3) of the blade can orientate itself with respect to the proximal portion (1 ).
Abstract:
Disclosed is a device for driving model airplanes (1), comprising a stationary fixture (2, 12), a housing (3, 13) that is rotatably mounted thereupon, and an arm (4) which is located on the housing for fastening a model airplane. The housing (3, 13) is provided with a power supply unit in the form of batteries (2) or rechargeable batteries and control electronics that are fed therewith. The power supply unit and control electronics are used for feeding at least one electric motor that is placed inside the model airplane (1). The wires between the control electronics and the electric motor are disposed on or inside the arm (4) while the arm is joined to the control electronics via a plug-in connection. A switch is provided on the inventive device for turning the power supply on and off.
Abstract:
A method and apparatus for controlling a powered craft in flight by an unsupported hand held control element. The position and attitude of the craft are controlled by the position and attitude of the control element. The position and attitude of the craft is determined with respect to a straight line between the controller and the craft, for example a beam of radiation. The controller and the craft are both provided with transducers comprising emitter and/or detector arrays in communication with one another.

Abstract:
A remotely controlled toy flying system (10) in which the pitch of the toy flying device (24) is controlled by the same drive shaft (30) and drive shaft tube (32) that is used to transmit power to the rotor (28) of the toy flying device (24). A child can easily control the pitch of the toy flying device (24) by a rotating knob (46). Rotation of the knob (46) displaces the drive shaft (30), lifts the pitch link member (20), and rotates the pitch shaft (22) and the toy flying device (24). Tilting of the toy flying device (24) causes the rotor (28) to have a horizontal component of thrust causing the toy flying device (10) to rotate in a fixed arc around the pivot member (42) in the direction in which the knob (46) is rotated by the child. Speed of the toy flying device rotor (28) is controlled by the fore and aft motion of the lever (48).
Abstract:
A flight control system for at least one tethered gyroglider along a flight path consistent with at least one flight mission is configured to fly the gyroglider within a portfolio of winds, managing an interaction between portfolios of at least four envelopes including wind, gyroglider performance, flight and base station. Every flight mission corresponds to at least one flight path associated with a set containing at least one first value and at least one second value. The control system is provided with a learning and library manager comprising a repository having stored sets of first values and associated second values for each flight path. The current first values associated with a current mission are corrected based on predicted or experienced flight paths and measurable outputs to attain the desired flight path. The corrected, experienced values, flight path and measurable output are further stored in the repository for further learning.
