The present invention relates generally to flow regulation in aircraft systems. More particularly, the present invention relates to a flow regulator 100 and a high-lift system 200 for an aircraft incorporating such a flow regulator 100. The flow regulator 100 comprises a fluid input port 102 for receiving a pressurized fluid, a fluid output port 104 for providing fluid having a regulated flow rate, and a regulator valve 106 connected in fluid communication between the fluid input port 102 and the fluid output port 104. The regulator valve 106 is operable to provide regulated fluid at a substantially constant output flow rate to the fluid output port 104. The flow regulator 100 also includes a flow switching mechanism 108 for switching the substantially constant output flow of the flow regulated fluid provided by the regulator valve 106 between a first flow rate and a second flow rate, the first flow rate being less than the second flow rate.
A control surface element skew and/or loss detection system (100) is provided which combines a cable (168, 178) system linked to movement transducers (120) via mechanical links (114, 116) connecting the fixed wing structure (102) to the control surface elements (106, 112).
The present invention relates generally to flow regulation in aircraft systems. More particularly, the present invention relates to a flow regulator (100) and a high-lift system (200) for an aircraft incorporating such a flow regulator (100). The flow regulator (100) comprises a fluid input port 102 for receiving a pressurised fluid, a fluid output port (104) for providing fluid having a regulated flow rate, and a regulator valve (106) connected in fluid communication between the fluid input port (102) and the fluid output port (104). The regulator valve 106 is operable to provide regulated fluid at a substantially constant output flow rate to the fluid output port (104).

The present invention provides a panel device for modifying airflow about a wing (110) of an aircraft (120). The panel device may be used to provide a flap (100) or a leading edge slat. The panel device comprises a plurality of independently operable panel sub-sections (102, 104, 106). Each panel sub-section (102, 104, 106) has a panel authority lower than a predetermined critical threshold value so as to allow simple economic control of synchronisation. The panel device provides for both improved fuel efficiency as well as enhanced operational safety of the aircraft (120).
The present invention relates to a hydraulic actuator, in particular an electrically driven hydraulic actuator. An example of the electrically driven hydraulic actuator comprises a variable speed motor, a variable capacity displacement pump arranged to be driven by the variable speed motor; and a hydraulic actuator driven by the variable displacement pump. Being able to vary the speed of the motor and the displacement of the pump enables the actuator to be able to be operated very flexibly and the motor does not have to be driven at an excessively high or low speed reducing wear and over-heating of the motor.

A diaphragm coupling having first and second diaphragm plates that are joined together around their outer edges. Each diaphragm plate has a central, axially-extending hub. The hub of the first plate supports within it a pin member having an outwardly projecting shoulder at each end adapted to engage an internal shoulder on the hub of the first plate at one end and an internal shoulder on the hub of the second plate at the other end so as to limit axial separation of the two hubs—from one another.

MAGNETIC TORQUE COUPLING HAVING AN INNER ROTOR MOUNTED FOR AXIAL MOVEMENT RELATIVE TO AN OUTER ROTOR
The invention broadly provides a torque coupling (20) arranged to act between a variable-speed rotating shaft (21) and an energy-storage device (22), comprising: an inner rotor (23) mounted for rotation with the shaft and mounted for movement along the axis of the shaft; an outer rotor (25) surrounding the shaft, adapted to surround the inner rotor, and operatively connected to the energy-storage device, the inner rotor being rotationally coupled to the outer rotor when the inner rotor is arranged within the outer rotor and being rotationally uncoupled from the outer rotor when the inner rotor is arranged axially beyond the outer rotor; and an actuator (A) operatively arranged to selectively move the inner rotor axially along the shaft axis relative to the outer rotor; whereby the inner rotor may be selectively moved to a position relative to the outer rotor to permit the transfer of energy between the shaft and the energy-storage device.
