摘要： Anti-rotation device (15) consists of a thin washer (16) having a pair of circumferentially and radially spaced tabs (19, 20) protruding axially from one side thereof which are adapted to be received in the gaps (10, 11) in the inner and outer rings (5, 6), respectively, of a circumferential ring seal (1) to prevent the gaps (10,11) from aligning themselves. The tabs (19, 20) are desirably located approximately 180° apart to keep the ring gaps (10,11 ) on diametrically opposite sides of the seal (1).

摘要： Flow control valve (1) includes angled metering ports (37, 38 or 35', 36') in the valve sleeve (4) for directing the momentum of the fluid flow against the respective valve flow metering edges (51, 52 or 67, 69) in a direction producing an opening reaction force on the valve (5) upon initial valve opening in opposition to the usual axial flow forces tending to close the valve (5) to reduce the flow force gain acting on the valve (5). Preferably, the angled metering ports (37, 38 or 35', 36') are disposed at an angle of approximately 45° or greater from a line perpendicular to the valve axis. Also, a single set of circumferentially spaced angled metering ports (37, 38 or 35', 36') is desirably provided for each return or high pressure flow path (13, 14 or 21', 22') for producing the desired opening reaction force on the valve (1).

摘要： A composite pressure vessel (1) including a fluid port (22) extending through the composite sidewall structure (2) formed by providing a radial hole (26) through the sidewall structure (2) for receipt of an externally removable porting plug (24). The porting plug (24) is retained within the radial hole (26) by threaded engagement in an internally threaded grommet (28) which may either be incorporated into the composite windings (4, 6) of the sidewall structure (2) or held in place against the exterior surface of the sidewall structure (2) by local composite windings (30). At the inner end of the porting plug (24) is a seal groove (38) containing a ring seal (40) which is sized to form a fluid-tight seal around a porting hole (48) in a liner member (8) in the interior of the sidewall structure (2) to prevent fluid leakage between the porting plug (24) and liner member (8). The inner diameter of the seal groove (38) is formed by a reduced diameter end portion (36) at the inner end of the porting plug (24), whereas the outer diameter of the seal groove (38) is formed by a back-up ring (42) surrounding such reduced diameter end portion (36) in radial spaced relation therefrom. The back-up ring (42) is preloaded against the liner member (8) during threading of the porting plug (24) into the grommet (28) to ensure a tight fit between the back-up ring (42) and liner member (8).

摘要： A method of adaptive control for use in a controlled system (12) having an adjustable forward loop gain and a control system apparatus for carrying out the method are disclosed. The control system (12) measures the value of a parameter which is to be controlled and generates an error signal (E) by comparing the measured valve of the parameter with a desired valve. The error signal is squared and the time derivative of the squared error signal is obtained. The control system compares the length of time that the derivative so obtained has a positive value to the time it has a negative value to obtain a gain control signal, and applies the gain control signal to the forward loop gain. The gain control signal reduces the adjustable forward loop gain until a preselected margin of stability in the controlled system is obtained.

摘要： Duel tandem composite cylinder assembly (1, 96) includes a cylinder (2) having circumferential or hoop stress windings (20,21) surrounding a pair of hydraulic chambers (3, 4) in series to react the circumferential loads and prevent diametrical expansion of the hydraulic chambers. Longitudinal tension windings (70) extend over substantially the entire length of the cylinder outwardly of the circumferential windings to react the axial loads which the cylinder must contain. Compressive cylinder composite windings (65, 95) are also provided for carrying compressive toads generated within the cylinder. The hydraulic chambers are desirably lined with removable liner members (22, 23) to facilitate changing of seals and refurbishment of the cylinder.

摘要： A fluid servo actuator control/damping mechanism (10) and method which utilize and combine the functions of an electro-mechanically driven servo valve (26) to achieve ram (16) or actuator (12,14) fluid flow and load control even after loss of fluid power as well as the main ram position control function under normal operating conditions. The mechanism comprises a main control servo valve (26) including a positionable valve element (34) for selective application of fluid power to a ram (16), a sensor (88) connectable to the ram for providing ram load feedback information, and an electro-mechanical drive (78) operable independently of fluid power for selectively positioning the valve element (34) under normal operating conditions for controlled actuation of the same and, upon loss of fluid power, for providing variable orifices to controllably meter bypass fluid flow across the ram by utilizing the existing metering pattern of the servo valve (26) and modulating the valve element (34) thereof in response to feedback information received from the sensor (88), for actively controlled damping of the ram.

摘要： A control actuation system (70) for an aircraft including an electro-mechanically controlled, hydraulically powered actuator (72) for driving a main control valve (26) of a dual hydraulic servo-actuator control system (10). The actuator includes a tandem piston (74) connected to the main control valve (26) which is controllably positioned by a staged valve (125) of relatively short stroke whereby a force motor (218) of minimum size and energy requirements may be used to directly drive the valve. The staged valve (125) includes a linearly movable valve plunger (184) for simultaneously controlling the differential application of fluid pressure from respective hydraulic system on opposed pressure surfaces (94, 96 and 98, 100) of respective piston sections (90, 92) to cause movement of the piston (74) in response to relatively short axial movement of the valve plunger as long as at least one hydraulic system remains operative. Also, the staged valve (125) includes a fault control valve sleeve (130) concentric with the valve plunger (184) which, upon shut-down or failure of both hydraulic systems, moves linearly to render the valve plunger inoperative and release fluid pressure from opposed, corresponding pressure surfaces (94, 96 and 98, 100) of the tandem piston to respective returns therefor through respective centering rate control orifices (118,120, 250, 252) in the fault control valve sleeve (130) as the piston in moved to a neutral position by a centering spring device (254) acting on the main control valve.
摘要翻译：一种用于飞行器的控制致动系统（70），其包括用于驱动双液压伺服致动器控制系统（10）的主控制阀（26）的电机械控制的液压动力致动器（72）。致动器包括连接到主控制阀（26）的串联活塞（74），其通过相对较短行程的分级阀（125）可控地定位，由此可以使用最小尺寸和能量要求的力马达（218）来直接驱动阀门。分级阀125包括可直线运动的阀柱塞184，用于同时控制相应的液压系统在相应的活塞部分（90,92）的相对的压力表面（94,96和98,100）上差动地施加流体压力，以便只要至少一个液压系统保持工作，响应于阀柱塞的相对短的轴向运动而引起活塞（74）的移动。此外，分级阀125还包括与阀柱塞184同心的故障控制阀套管130，在两个液压系统关闭或故障时，该活塞阀线性移动，使得阀柱塞不起作用并释放流体压力通过作为活塞的故障控制阀套（130）中的相应的对中速度控制孔（118,120,250,252），从串联活塞的相对的相应的压力表面（94,96和98,100）到相应的回程，通过作用在主控制阀上的定心弹簧装置（254）移动到中立位置。
