Aircraft control device, a corresponding aircraft, and a method of controlling an aircraft
A control device for controlling an aircraft, the control device including at least one motor-driven trim actuator with active type anchoring, the trim actuator including at least one electric motor, at least one electronic power circuit for electrically powering the electric motor(s), and speed reduction means for driving rotation of an outlet shaft of the trim actuator. The control device implements three distinct servo-control loops that are nested in one another, these three servo-control loops being formed by an electric current servo-control loop, a speed servo-control loop, and a force servo-control loop.
Artificial force feel generating device for a vehicle control system of a vehicle and, in particular, of an aircraft
An artificial force feel generating device for generation of an artificial feeling of force on an inceptor of a vehicle control system, the inceptor being adapted for controlling a servo-assisted control unit of the vehicle control system via a mechanical linkage, wherein at least one first force generating device and at least one second force generating device are mechanically connected to the inceptor, the first force generating device being provided for generating a nominal force acting in operation on the inceptor and the second force generating device being provided for generating a tactile cue force acting in operation on the inceptor, the first and second force generating devices being arranged in parallel. The invention relates further to an aircraft comprising such an artificial force feel generating device.
Rudder Bar For Aircraft With A One-Piece And Detachable Main Module
A rudder bar includes a main module provided at least with pedals and with all the elements subject to maintenance, the main module being one-piece and detachable relative to a support frame integrated into the floor of the cockpit of the aircraft, so as to exhibit significant flexibility with respect to its maintainability, particularly in the event of the failure of a component, by allowing quick intervention both on a local level and an overall level.
Rotorcraft control mode transition smoothing
A method of operating a rotorcraft includes transitioning from a first mode to a second mode when a velocity of the rotorcraft exceeds a first velocity threshold. Transitioning between the first and second modes includes fading out a gain of a dynamic controller over a first period of time, and decreasing a value of an integrator of the dynamic controller over a second period of time. In the first mode, the translational speed of the rotorcraft is determined based on a pilot stick signal, and in the second mode, an output of an attitude rate controller is proportional to an amplitude of the pilot stick signal.
Inceptor apparatus
An active inceptor apparatus and method for operating a machine. The apparatus comprises a stick member having a grip portion, the stick member being pivotably mounted relative to a housing. It further comprises a position sensor responsive to, and for generating signals indicative of, stick member position. A force sensor is provided on the stick member responsive to, and for generating signals indicative of, force applied to the stick by a user. The apparatus also includes a control unit operable to receive the position and force signals from the position and force sensors respectively. The control unit is operable to process the signals according to a predetermined relationship to determine a value FD indicative of force applied to the stick member relative to displacement of the stick member. The control unit is also operable to generate machine control signals as a function of position signals and force signals in dependence upon the value FD, for communication to the machine.
Above-the-floor rudder and brake control system
A modular brake and rudder control system usable in an aircraft. The modular system mounts atop the flight deck floor without penetrating through the floor when the system is operatively connected to the aircraft's fly-by-wire brake and rudder systems. Pedal assemblies extending from the housing are rotatable and longitudinally moveable relative to the housing. A brake control system fully contained in the housing is connected to the pedal assemblies and provides a signal via an electrical connector to the fly-by-wire brake system upon rotation of the pedals. A rudder control system is fully contained in the housing and is operable independent of the brake control system. The rudder control system detects longitudinal motion of the pedal assemblies and provides a signal via an electrical connector to the fly-by-wire rudder system. The housing, the electrical connectors, the pedal assemblies, the brake control system and the rudder control system define a modular component installable and removable from the cockpit as a unit.
COMBINED ACTIVE STICK AND CONTROL BOOST ACTUATOR SYSTEM
A combined active stick and control boost actuator system for a control surface has a control stick engaged to a mechanical flight control structure with a linkage configured to move a control surface. A mechanical interconnect engages the linkage and has a control stick connection. An integrated actuator is separably connected to the mechanical interconnect intermediate the control stick connection and the linkage. A stick force sensor is configured to provide a stick force signal. A flight control system receives the stick force signal and provides an actuator position control signal to the integrated actuator. The integrated actuator moves to a prescribed position in accordance with a force feel profile providing pilot variable tactile cueing and power boost to reduce both fatigue and workload.
METHOD FOR ASSISTING THE PILOTING OF AN AIRCRAFT
A method for assisting the piloting of an aircraft includes the following steps: detecting obstacles in an environment of the aircraft; determining a protection zone surrounding each detected obstacle; determining an initial trajectory followed by the aircraft; if the initial trajectory enters a protection zone, determining a corrected trajectory such that the aircraft avoids the protection zone; applying the corrected trajectory to the aircraft; and outputting at least one haptic alert in a flight control stick of the aircraft, the haptic alert indicating a direction of deflection applied to the aircraft when applying the corrected trajectory. Piloting is thus assisted by providing ergonomic and simple alerts, so as to guarantee a safe trajectory for the aircraft.
Aircraft inceptor apparatus and aircraft flight control system
An inceptor apparatus for an aircraft having a primary inceptor member provided in the form of a stick member having a grip portion, at which the stick member can be gripped by a pilot's hand, and a secondary inceptor member provided at an upper portion of the primary inceptor member and having an actuating portion, at which the secondary inceptor member can be manually actuated by a pilot's thumb. Both inceptor members have associated a respective sensor assembly which is provided to generate electronic flight control signals or commands in response to at least one of i) pivoting movements of the respective inceptor member around each of two independent maneuvering axes associated to the inceptor member, ii) forces acting on or via the respective inceptor member in pivoting directions with respect to each of the maneuvering axes, and iii) lateral flexing or bending of the respective inceptor member.
