摘要： An actuation system (16) for a control surface (6c, 8c, 10c) for an aircraft (2) is disclosed. The actuation system (16) comprises a first, second, third and fourth actuator (18, 20, 22, 24), a first and second bell crank (26, 28), and at least one push pull rod system (30). Each of the first and second bell cranks (26, 28) comprises a first and a second crank arm (90, 98, 92, 100), the first and second crank arms (90, 98, 92, 100) intersect with and are joined to each other at an intersection (93, 101), the first and second crank arms (90, 98, 92, 100) extend from the intersection (93, 101) at an angle to each other, the first bell crank (26) is pivotally connected to the sub-structure by a first pivot (86) extending through the first bell crank's intersection (93), and the second bell crank (28) is pivotally connected to the sub-structure by a second pivot (94) extending through the second bell crank's intersection (101). The first and third actuators (18, 22) have first and second ends, the first ends of the first and third actuators are connected to the sub-structure, the second end of the first actuator is connected to the first crank arm of the first bell crank at a first connection position, the second end of the third actuator is connected to the first crank arm of the first bell crank at a third connection position. The second and fourth actuators (20, 24) have first and second ends, the first ends of the second and fourth actuators are connected to the sub-structure, the second end of the second actuator is connected to the first crank arm of the second bell crank at a second connection position, the second end of the fourth actuator is connected to the first crank arm of the second bell crank at a fourth connection position. In the first bell crank (26) the distance (D1) between the first connection position and the first pivot (86) is greater than the distance (D3) between the third connection position and the first pivot (86), and in the second bell crank (28) the distance (D2) between the second connection position and the second pivot (94) is greater than the distance (D4) between the fourth connection position and the second pivot (94).

摘要： The present disclosure provides a hydraulic actuator (2) comprising a piston (4) and a cylinder (6). The piston (4) is axially movable within the cylinder (6). A stroke end damping valve (32) is provided in a hydraulic fluid flow passage (40) of the actuator (2) and adjacent an end (10) of the cylinder (6). The stroke end damping valve (32) comprises a damping orifice (34) and a valve element (36) for selectively varying the area of the damping orifice (34) and thereby changing the damping provided by the orifice (34). The valve element (36) projects from a wall (8) of the cylinder (6) into the cylinder (6) and is engageable by the piston (4) as the piston (4) moves towards the end (10) of the cylinder (6). This reduces the area of the damping orifice (34) and thereby increases the damping effect on the piston (4) towards the end of its stroke in the cylinder (6).

摘要： An abradable seal is provided, comprising an outer ring arrangement (120, 150) and an energiser (140) for urging said outer ring arrangement against an opposing surface, wherein an outermost surface (123) of said outer ring arrangement defines a sealing surface of said abradable seal;
wherein said outer ring arrangement is configured such that after a first period of operation said sealing surface suddenly transitions from having a relatively large surface area to having a relatively small surface area, so as to cause a sudden increase in internal leakage across the seal at said transition.

摘要： The present disclosure provides an actuator control arrangement comprising: a hydraulic actuator (100) having a housing (200) and a piston rod (300) axially moveable within the housing between a neutral position, a retracted position and an extended position with respect to the housing in response to application of pressure to the piston rod; a solenoid valve (140) arranged between a pressure source and the actuator, the solenoid valve switchable between a first mode and a second mode in response to an electric control signal, wherein, in the first mode, the solenoid valve creates a fluid flow path from the pressure source to the actuator and in the second mode, the solenoid valve creates a fluid flow path to release pressure from the actuator; and an anti-extension valve (130) provided between the pressure source and the actuator, configured to move between a first position in which a fluid path is created between the pressure source and the actuator and a second, anti-extension position to prevent extension of the piston rod with respect to the housing in the event of pressure loss; wherein the anti-extension valve has a first pressure input (131) arranged to receive pressure from the pressure source and a second pressure input (132) arranged to receive pressure from the actuator, the sum of the pressure at the first input and at the second input acting against a spring (600) biasing the anti-extension valve into the second position; and further comprising an outlet port (800) in the actuator housing arranged to be closed when the solenoid valve is in the first position and open when the solenoid valve is in the second position and, when open, to convey pressure from the actuator to a third pressure input (133) of the anti-extension valve to add to the pressure acting against the spring. Thus, in the case of the piston rod being in negative stroke and in the event of pressure failure, less force is required to disengage the anti-extension function because, the force is doubled when applied to the end of the anti-extension valve acting against the spring bias.

摘要： A trimmable horizontal stabiliser actuator (THSA) control system 6 for an aircraft is described. The THSA control system 6 uses electronic elements and may replace pre-existing mechanical trim control systems. The THSA control system comprises: at least one main THSA motor 10 for driving the THSA 8 in response to inputs from a flight control computer (FCC); a pilot trim control system for manual control of the THSA 8 by a pilot overriding the FCC, wherein the pilot trim control system comprises a trim control 2 for receiving an input from the pilot, the trim control 2 including a trim control sensor 18 for detecting the input from the pilot and providing a pilot trim control signal; a THSA trim control motor 12 for driving the THSA 8 in response to the pilot trim control signal; and an electronic override system 22 for giving inputs from the pilot priority over inputs from the FCC by preventing the at least one main THSA motor 10 from driving the THSA when an input from the pilot via the pilot trim control system requires a different state for the THSA than an input from the FCC.
