L'invention concerne également une installation pour la mise en œuvre du procédé.
Abstract:
Disclosed is a method of control and stabilisation of aircraft. In one aspect pitch and roll may be controlled by a simple method of signalling to or from a reference location in a number of different ways. Both height and lateral position may be controlled. In a further aspect, polarised light may be used to determine the relative rotation of the aircraft. Additionally, preferred aircraft and associated features are disclosed.
Abstract:
A flying amusement device (10) including first and second rotary elements (12, 14) separated by a hub (16). Each of the rotary elements includes a set of lift members (18, 20) which provide lift in a common direction when the device is rotated about the hub. A length of flexible line (26) is connected to the hub (16) and wound thereabout prior to use. The device is held in the user's hand with the free end of the flexible line connected to the user's throwing hand. The device is then thrown outwardly from the body of the user with a snapping motion of the wrist to impart rotation to the device. This rotation produces lift, and further rotation is imparted to the device due to the device unwinding from the flexible line as it travels away from the user. Upon fully unwinding the flexible line (26) from the hub (16), the continued rotation of the device (10) causes the flexible line (26) to be rewound upon the hub (16), thus drawing the device back towards the user. During the travel of the device (10) away from and towards the user, the continued rotation of the device produces a lift which causes the device to fly through the air.
Abstract:
L'invention concerne un système d'alimentation électrique d'un appareil téléopéré captif (10), comportant une source d'alimentation électrique (21) configurée pour fournir une énergie électrique, et un câble électrique (20) connecté électriquement à ladite source d'alimentation électrique et configuré pour acheminer ladite énergie électrique jusqu'au dit appareil téléopéré captif pour alimenter au moins une machine électrique tournante et/ou des éléments systémiques embarqués dans ledit appareil téléopéré captif; caractérisé en ce que ladite source d'alimentation électrique est configurée pour fournir une haute tension alternative triphasée, ledit câble électrique est configuré pour faire cheminer ladite haute tension alternative triphasée et ledit système comporte en outre un dispositif de gestion et de conversion d'énergie embarqué dans ledit appareil téléopéré captif et configuré pour redresser ladite haute tension alternative triphasée reçue en une haute tension continue et pour abaisser ladite haute tension continue en basse tension continue
Abstract:
An airborne drone training track includes both a ground track and a ceiling track. The ceiling track can be disposed above and be at least essentially aligned with the ground track. Airborne drone attachment tethers movably attach an airborne drone to each of these tracks. A lower airborne drone attachment tether movably attaches to the ground track and to a bottom portion of the airborne drone. A plurality of upper airborne drone attachment tethers movably attach to the ceiling track and to upper portions of the airborne drone. By one approach there is only one lower airborne drone attachment tether and four upper airborne drone attachment tethers.
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 ).
