摘要： Fuel is selectively jettisoned through the engine of an aircraft by way of a normally closed, solenoid-operated jettison valve which is fed from the boost pump in the engine fuel system. The jettison valve is servo activated by the main fuel flow so that the engine must be running for the opening of the solenoid valve to occur. For an engine having an augmenter, other interlocks are provided to prevent the jettison of fuel when the augmenter is in use and to preclude the ignition function to the augmenter while fuel is being jettisoned.

摘要： A compound propulsor for powering a vehicle, such as an aircraft. A compound propulsor includes a core gas turbine engine, a fan encased within a cowl, at least one propeller, and drive means for distributing a portion of the power produced by the core engine to the fan and another portion to the propeller. Preferably, the compound propulsor also includes variable geometry inlet guide vanes for varying the portions of power distributed to the fan and propeller.

摘要： A gas turbine engine is provided with a long nacelle which forms both the inlet and exhaust of the engine. The nacelle is spaced apart from a core engine to define an annular bypass duct therebetween. The incoming air stream is pressurized by a front fan disposed in the inlet and then divided between the core engine and bypass duct. A lobed mixer device is provided downstream of the core engine to intermix the core engine and bypass duct exhaust streams. The mixed streams are discharged from a common nozzle formed at the downstream end of the nacelle. A non-redundant system of mounts are provided to secure the engine to the pylon of an aircraft in such a manner as to reduce engine thrust induced bending loads and insure symmetry of these thrust loads. The total reaction of the thrust loads at the mounting points is reduced by a unique interlocking system by which all of the major engine assemblies are joined. The engine is configured such that it may be easily removed from an aircraft and replaced with a spare engine in minimum time. This quick change capability is achieved by mounting the engine such that it may be removed from the aircraft by disconnecting the forward and rear mounts and an engine bleed duct. The mid portion of the engine nacelle and all accessories mounted thereon remain with the aircraft.
摘要翻译： 燃气涡轮发动机设置有形成发动机的入口和排气两者的长机舱。 机舱与核心发动机间隔开，以在它们之间限定环形旁路管道。 进入的空气流由设置在入口中的前风扇加压，然后在核心发动机和旁路管道之间分配。 在核心发动机的下游设置有一个叶片混合装置，以使核心发动机和旁路管道废气流混合。 混合流从形成在机舱下游端的公共喷嘴排出。 提供非冗余的安装系统以将发动机固定在飞机的塔架上，以减少发动机推力引起的弯曲载荷并确保这些推力载荷的对称性。 通过独特的联锁系统减少安装点处的推力负载的总反应，所有的主要发动机组件都通过该互锁系统连接。 发动机被配置为使得其可以容易地从飞行器移除并且在最短时间内用备用发动机替换。 这种快速更换能力是通过安装发动机来实现的，使得可以通过断开前部和后部支架以及发动机排放管道从飞机上移除。 发动机舱的中部和安装在其上的所有附件都保留在飞机上。

摘要： Drive means for connecting a gas turbine engine to its accessories are so constructed as to allow the accessories to be selectively positioned to any one of several predetermined circumferential positions about the perimeter of the engine. This feature permits convenient mounting of the same engine upon vehicles demanding radically different engine mounting arrangements.

摘要： A nacelle for use with a gas turbine engine is provided with an integral webbed structure resembling a spoked wheel for rigidly interconnecting the nacelle and engine. The nacelle is entirely supported in its spacial relationship with the engine by means of the webbed structure. The inner surface of the nacelle defines the outer limits of the engine motive fluid flow annulus while the outer surface of the nacelle defines a steamlined envelope for the engine.

摘要： A propeller engine system with means for generating electric power within a rotatable hub is disclosed. The means include a shaft extending into the hub so that the hub and shaft are differentially rotatable. Magnetic means are fixed to the shaft and winding means are fixed to the hub so that either rotation of the rotor shaft or hub induces an electric current in the winding means.

摘要： In a mixed flow gas turbine engine of the type which includes an outer nacelle spaced apart from a core engine to define an annular bypass duct therebetween, there is provided a convoluted lobed mixer having a plurality of cold chutes in flow communication with the bypass duct and hot chutes in flow communication with the core engine. In order to suppress engine turbomachinery and exhaust noise, the mixer is alternatively provided with various combinations of acoustically treated lobes, spool pieces, radial splitters, and/or circumferential splitters. These acoustic treatments act in conjunction with an acoustically treated nozzle assembly and an acoustically treated plug assembly to provide an effective low aerodynamic pressure loss noise suppression system.
