142 ROTOR A STRUCTURE EN NID D'ABEILLE CIRCULAIRE EP04714335.9 2004-02-25 EP1719918A1 2006-11-08 Sanchez Sanchez, Felix

Rotor rond en nid d'abeilles pour améliorer le rendement des hélices conventionnelles dans son usage comme rotor pour engins volants, motopompes, embarcations, ainsi que pour toutes applications hydrauliques ou pneumatiques, disposant de pièces hélicoïdales initiées dans son cube ou noyau circulaire et montées sur un ou plusieurs cylindres tubulaires et concentriques entre eux.

144 IMPROVED VERTICAL TAKE-OFF AND LANDING VEHICLES EP03709001.6 2003-02-06 EP1478570A2 2004-11-24 MOLLER, Paul, S.
A VTOL vehicle including a fuselage with two foldable wings, two tiltable nacelles attached to the wings, a vertical stabilizer, a horizontal stabilizer, and two auxiliary thrusters. Each nacelle contains a system of vanes located at the rear opening thereof, and actuators are provided for extending and retracting the vanes in conjunction with nacelle tilting mechanisms to deflect the airflow over a predetermined range of angles from the horizontal. Each nacelle also contains two rotary engines, each of which directly drives a fan. The fans face each other and operate in counter-rotating directions at the same rotational speed. An alternative embodiment includes two additional nacelles attached to the fuselage instead of having the auxiliary thrusters. A redundant computerized flight control system maintains stability of the vehicle as it transitions from one flight mode to another.
145 VERTICAL LIFT FLYING CRAFT EP02706116.7 2002-01-31 EP1441946A2 2004-08-04 Baldwin, Gilbert
A disclosed vertical lift flying craft (10) includes a lift unit (20) that, during operation, develops a force including an upward component. A payload unit (50) suspends from the lift unit (20).

146 VORTEX GENERATOR EP00978281.4 2000-10-27 EP1224396A1 2002-07-24 REINFELD, David; ILLINGWORTH, Lewis
A vortex generating apparatus (60) has the capability of attracting and removably adhering one or more solid objects. The apparatus (60) comprises an impeller housed within a shell. The vortex attractor generates a vortical fluid flow (69a) generally in the form of a helical or spiral shaped flow. The fluid flow (69a) creates a low pressure region extending from the impeller end of the device. This low pressure region is contained by the walls of the fluid flow, thus directing the attractive forces toward a surface and minimizing effects of ambient fluid on the system. When the surface is part of a stationary object, wall, floor or ceiling, the vortex attractor may move toward and adhere to the surface. When the surface is part of a movable object, the vortex attractor may attract the object and maintain the attracted position.
147 PROPULSIVE THRUST RING SYSTEM. EP92912005 1992-05-28 EP0586511A4 1994-11-17 LEMONT HAROLD E
a low-aspect ratio propeller system is provided with a multiple ring structure (42) formed with a plurality of circular or non-circular, annular, narrow equivalent air foil rings (56.1, 56.2, 56.3, 56.4) which are held by rails (40) in a predetermined relationship with the propeller blades (44). The upstream ring (56.1) is located downstream from the tip vortex of the propeller (44) within the axial span of the propeller. One or more additional downstream-located rings (56.2, 56.3, 56.4) are used so as to provide at least one annular multiple ring-defined pump aperture (60, 62, 64) through which peripheral vortices generated by the propeller blades (44) or fan blades may enhance the mass flow. These vortices increase thrust because their induction action on the rings (56.1, 56.2, 56.3, 56.4) increase beneficial ring flow circulation. Augmented ring flow reduces the velocities in the expanding wake by increasing the mass flow. The destruction of tip and root vortices reduces noise. The multiple ring structure (42) also serves as a guard.
148 PROPULSIVE THRUST RING SYSTEM EP92912005.0 1992-05-28 EP0586511A1 1994-03-16 LEMONT, Harold, E.
Un système d'hélice à faible rapport d'allongement est pourvu d'une structure (42) à anneaux multiples composée d'une multiplicité d'anneaux sustentateurs (56.1, 56.2, 56.3, 56.4) circulaire ou non, annulaire, étroits et équivalents, qui sont maintenus par des barres (40) en un rapport prédéterminé avec des pales de l'hélice (44). L'anneau amont (56.1) est placé en aval par rapport à l'extrémité du tourbillon (44) de l'hélice dans l'envergure axiale de l'hélice. Un ou plusieurs anneaux additionnels (56.2, 56.3, 56.4) situé(s) en aval sont utilisés pour former au moins une ouverture de pompage (60, 62, 64) annulaire définie par plusieurs anneaux, et à travers laquelle des tourbillons périphériques produits par les pales d'hélice (44) ou de la soufflante peuvent augmenter le flux massique. Ces tourbillons augmentent la poussée du fait que leur effet d'induction sur les anneaux (56.1, 56.2, 56.3, 56.4) augmentent une circulation de flux annulaire. Le flux annulaire augmenté réduit les vitesses dans le sillage qui va s'élargissant en augmentant le flux massique. L'annulation des tourbillons d'extrémité et de base permet de réduire le bruit. La structure à plusieurs anneaux (42) sert aussi d'élément de protection.

A stage of fan blades (31, 33) is attached to each hub (27, 29) and radiates outwardly therefrom. The tips of the blades (31, 33) of at least one of the stages are attached to a hoop (23/25 or 61) that encircles the tips of the blades (31, 33) of both stages. Due to the attachment of the hoop (23/25 or 61) to the blades (31, 33), the hoop rotates as the hubs (27, 29) are rotated by the turbojet (19). The pitch of the blades of at least one of the stages is adjustable.
