| 7338011 | Method making it possible to prevent vibration of a rudder of an aircraft and aircraft using this method A method for preventing vibration of a rudder of an aircraft may have, on a lateral aerodynamic surface of the aircraft's rudder, a protruding aerodynamic element capable of generating an aerodynamic effect tending to rotate the rudder about its articulation axis. A... | 03/04/2008 |
| 7331548 | Control linkage for T-tail aircraft elevator surfaces Systems and methods for implementing control linkages that may be employed to produce synchronous motion in two adjacent controlled devices controlled by a common input. In one example implementation, a semi-rigid modified constant velocity (CV) joint control linkag... | 02/19/2008 |
| 7051976 | Process for improving the maneuverability of an aircraft during a resource Process for improving the maneuverability of an aircraft during a resource. According to the invention, prior to the resource, the adjustable horizontal tailplane (2) is nose-up deflected and the elevators (4) are nose-down deflected. ... | 05/30/2006 |
| 4765572 | System for controlling a mobile aerodynamic surface of an aircraft This invention relates to a system for controlling an aerodynamic surface mounted mobile on an aircraft so as to be able to pivot freely about a fixed axis and provided with a tab itself articulated on the trailing edge of the aerodynamic surface, the sys... | 08/23/1988 |
| 4595158 | Aircraft control surface actuation and counterbalancing A flight control surface (1) is supported from an aircraft frame structure (12), for pivotal movement about a hinge axis. The surface (10) is deployed against an aerodynamic load which is a function of surface deflection and imposes a torque on the flight... | 06/17/1986 |
| 4479620 | Wing load alleviation system using tabbed allerons A wing load alleviation system for redistributing aircraft loads encountered during flight by symmetrically deflecting the outboard ailerons of the aircraft includes a trailing edge tab pivotally supported on each outboard aileron. As each outboard ailero... | 10/30/1984 |
| 4431149 | Geared tab An improved geared tab configuration for a moveable airfoil, such as an elevator of an aircraft, is provided which comprises a tab pivotally connected to the airfoil, and linkage connecting the airfoil to the tab for simultaneous opposing pivotal movement... | 02/14/1984 |
