摘要： A linkage system is disclosed adapted to be connected between a pilot's input lever and an engine power output lever. The linkage system is operative to vary the displacement ratio characteristics between the input and output levers. More specifically, during the first portion of input lever stroke, wherein shaft horsepower is raised from a ground idle speed to flight speed, the output lever is displaced an amount greater than the amount the input lever is displaced. In contrast, during the second portion of the stroke, corresponding to the upper range of shaft horsepower used in flight, a fixed amount of displacement of the input lever results in a smaller displacement of the output lever. By this arrangement, the control of the aircraft in flight is facilitated.

摘要： A self-aligning fuel nozzle assembly is provided for maintaining the alignment of a swirler member and a fuel nozzle upon displacement of the combustor liner relative to the combustor housing of a combustion chamber assembly in a turbine engine. The self-aligning fuel nozzle assembly mounts the swirler member to the combustor liner by a device having six degrees of freedom including a ball and socket joint which is placed within a structure so as to permit movement in the three main Cartesian directions of a rectangular axis system. The combustor liner is installed within the combustor housing in such manner that the fuel nozzle is slidably received within the swirler, with the swirler being biased against the fuel nozzle by a helical spring member forming part of the assembly. The self-aligning fuel nozzle assembly reduces the development of local stresses between the swirler and the fuel nozzle so that wearing between these parts is reduced. The swirler member and fuel nozzle are retained in aligned positions so that the self-aligning fuel nozzle assembly promotes improved fuel economy in the engine.
摘要翻译： 设置自对准燃料喷嘴组件，用于在涡轮发动机中相对于燃烧室组件的燃烧器壳体移动燃烧器衬套的位移时，维持旋流器构件和燃料喷嘴的对准。 自对准燃料喷嘴组件通过具有六个自由度的装置将旋流器构件安装到燃烧器衬套上，该装置包括一个放置在结构内的球窝接头，以允许在矩形轴的三个主笛卡尔方向上移动 系统。 燃烧器衬套以这样的方式安装在燃烧器壳体内，使得燃料喷嘴可旋转地容纳在旋流器内，其中旋流器通过构成组件的一部分的螺旋弹簧构件抵靠着燃料喷嘴。 自对准燃料喷嘴组件减少了旋流器和燃料喷嘴之间的局部应力的发展，从而减少了这些部件之间的磨损。 旋流器构件和燃料喷嘴保持在对准位置，使得自对准燃料喷嘴组件能够提高发动机中的燃料经济性。

摘要： An actuating linkage is provided for use in an aircraft engine having a double door-type particle separator, anti-icing system installed within its air intake ducts. The actuating linkage interconnects the deflecting vane and the bypass door through a coupler link. The deflecting vane is pivotally connected to a linear link which is connected to an actuator link about a pivot point. Movement of the actuator link varies the relative positions of the deflecting vane and the bypass door between ram mode and anti-icing mode positions. The actuating linkage partially balances the aerodynamic forces on the deflecting vane and bypass door so that the input required to operate the anti-icing system may be manually applied by the pilot. The actuating linkage is fail-safe, in that the linkage is operative such that should the actuator link extending to the pilot station fail, the aerodynamic forces on the bypass door cause the deflecting vane and bypass door to be actuated to the anti-icing mode position.
摘要翻译： 提供一种用于具有双门型颗粒分离器，安装在其进气管道内的防冰系统的飞机发动机的致动联动装置。 致动连杆通过联接器连杆将偏转叶片和旁路门互连。 偏转叶片枢转地连接到线性连杆，线性连杆围绕枢转点连接到致动器连杆。 致动器连杆的运动可以改变转向叶片和旁路门在柱塞模式与防冰模式位置之间的相对位置。 致动联动部分平衡偏转叶片和旁路门上的空气动力，使得操作防冰系统所需的输入可以由飞行员手动施加。 致动联动装置是故障安全的，因为联动是可操作的，使得如果延伸到先导站的致动器连杆失效，则旁路门上的气动力导致偏转叶片和旁路门被致动到防冰模式 位置。

摘要： An integral structure comprised of inner and outer coaxial shells mutually supported so as to define an annular passageway between the shells. The integral structure may be an air inlet housing for a gas turbine engine and the inner shell may be a hub member having a generally cylindrical passage extending therethrough for rotatably receiving a drive shaft. The inner shell has an outer surface of revolution. A plurality of duct preforms each include an inner duct surface shaped to congruently mate with said outer surface of said inner member, an outer duct surface spaced from said inner duct surface, and first and second lateral walls having opposed lateral surfaces. The duct member preforms are mounted onto the outer surface of the inner member in side-by-side relationship such that the first and second lateral walls on adjacent pairs of duct member preforms are coextensive and engaged. A coaxial outer shell preform is spaced from the inner member. Resin on the duct member preforms and the outer shell preform is cured to form an integral structure comprised of the inner member and outer shell member and a plurality of circumferentially spaced strut members defined by the first and second lateral walls.

摘要： A method is disclosed of making an integral structure comprised of inner and outer coaxial shells mutually supported so as to define an annular passageway between the shells. The integral structure may be an air inlet housing for a gas turbine engine and the inner shell may be a hub member having a generally cylindrical passage extending therethrough for rotatably receiving a drive shaft. The inner shell is formed by braiding on a shaped mandrel a plurality of fibers such as fiberglass, boron, carbon, or the like, to form an inner shell preform having an outer surface of revolution. A plurality of duct preforms are similarly formed on a conical mandrel, then removed, and administered onto an outer peripheral surface of a duct mold so as to define a modified shape. The modified duct preforms are then positioned onto the outer surface of the inner shell preform in side-by-side relationship such that the first and second lateral surfaces on adjacent modified duct preforms are coextensive and engaged, the plurality of modified duct preforms completely circumscribing the inner shell preform. Then, a plurality of fibers are braided across the plurality of outer modified duct surfaces of the duct preforms to form an outer shell preform spaced from and coaxial with the inner shell preform. Thereafter, resin is applied to the structure to encapsulate the braided inner shell preform, the braided modified duct preforms, and the braided outer shell preform. The resin is then cured to thereby complete fabrication of the integral structure.

摘要： A plurality of accessories operatively associated with a gas turbine engine are driven by electric motors. A first motor controller initiates operation of a starter/generator mechanically coupled to the engine. After the engine has been started, the motor controller is used to accelerate other accessory motors at a predetermined rate after which they are each electrically coupled to the starter/generator for continued operation. Throughout this operation, the first motor controller serves as a back up for a second motor controller which is dedicated to the operation of a fuel pump motor. Other modes of operation can be achieved as well by reason of the flexibility provided by motor driven accessories.
