摘要： A turbine engine particularly suited for VTOL aircraft is disclosed. According to various embodiments, the core of the turbine engine includes two spools—a low pressure (LP) spool and a high pressure (HP) spool—where the LP spool is independently mounted remote to the HP spool. The engine may be modulated for operation by a modulation diverter valve assembly and through the fuel flow to the engine. The power output from the engine can be modulated from high levels to low levels and vice versa through control of the air flow through the engine using the modulation diverter valve assembly. In lift mode operation both the LP and HP spools may be operational, while during the forward flight cruise mode of operation the HP spool is operational and the LP spool may or may not be operational depending upon the power required for the flight condition. For HP spool only operation, the LP spool may be shut down using the modulation diverter valve assembly and an inlet flow diverter valve assembly. The convertible configuration may be achieved by the diverter valving-enabled modulation of the engine airflow direction to produce a characteristic for one embodiment having shaft power output for the vertical lift mode to propulsive thrust output for forward flight mode.

摘要翻译： 公开了一种特别适用于VTOL飞机的涡轮发动机。 根据各种实施例，涡轮发动机的内核包括两个阀芯 - 低压（LP）阀芯和高压（HP）阀芯，其中LP阀芯独立地安装在HP阀芯上。 发动机可以通过调制转向阀组件进行调节，并通过燃油流向发动机。 来自发动机的功率输出可以通过使用调制分流阀组件控制通过发动机的气流，从高电平调制到低电平，反之亦然。 在提升模式操作中，LP和HP阀芯都可以运行，而在正向飞行巡航操作模式期间，HP阀芯可操作，并且LP阀芯可能或可能不会运行，具体取决于飞行条件所需的功率。 对于仅HP阀芯操作，LP阀芯可能会使用调压分流阀组件和入口流量分流阀组件关闭。 可转换配置可以通过发动机气流方向的转向阀启用调节来实现，以产生一个实施例的特征，该实施例具有用于垂直提升模式的轴功率输出用于向前飞行模式的推进推力输出。

摘要： A rotor support includes a first ring disposed around a first axis, a second ring disposed around the first axis downstream from the first ring, and a plurality of beams extending between the first and the second rings. Each beam is configured to provide an axial stiffness, when an axial force is exerted on the first ring, and a radial stiffness, when a radial force is exerted on the first ring. Each beam has a height extending parallel to a second axis and a width extending parallel to a third axis. The beams are distributed around the first ring to provide a substantially uniform circumferential axial stiffness around the rotor support, and the height of each beam is greater than the width of each beam. Damping can be provided by the placement of a damper between the rotor support and the support housing.

摘要： A heat transfer arrangement comprises a target member (28 or 30), and an impingement member (32). The impingement member (32) defines a fluid path (38 or 40) there through to direct fluid onto the target member. The arrangement includes a fluid directing formation (42) on the impingement member (32). The fluid path (38 or 40) extends through the fluid directory formation (42) such that the fluid path directs fluid to exit there from at an exit angle that is substantially orthogonal to the fluid directing formation.
