    • A turbine engine is disclosed that is capable of operating in an emergency power mode, an air breathing auxiliary power mode and a bypass bleed environmental control mode. In a preferred embodiment of the invention, the engine comprises in working fluid flow order a compressor for compressing air, a combustion chamber and a power turbine for extracting mechanical work from heated and/or compressed air. The compressor and turbine are separately coupled by a shaft which is also coupled to a generator for supplying electrical power and a cooling turbine for supplying cooled air to the aircraft cabin and avionics. The combustion chamber has an upstream combustor inlet and a downstream combustor inlet, each of which may admit compressed air either to be mixed with fuel for combustion, or to pass directly to the combustor outlet which is operatively attached to the power turbine section inlet. During emergency/starting operation, the combustion chamber and turbine section receive compressed air from a stored air accumulator through a stored air inlet. During normal air breathing operation, the combustion chamber and turbine section receive compressed air from a compressor through an air breathing inlet. During bypass bleed operation, the combustion chamber and turbine section receive compressed air from the aircraft main engine through a bypass bleed air inlet. The tri-mode operation is made possible by a unique two-way bypass ring having a plurality of axial passages communicating the stored air inlet and air breathing inlet with the upstream combustor inlet and a plurality of radial passages communicating the bypass bleed inlet with the downstream combustor inlet. A valving system selectively admits compressed air into the combustor and turbine section from the stored air inlet, air breathing inlet or bypass bleed inlet depending on the mode of operation.

    • A dual channel ignition circuit (Channel A and a Channel B). In a start sequence in which a successful ignition event occurs, an exciter controller first energizes only a primary ignition channel (Channel A). Once the exciter controller recognizes a success light-off, the alternate channel (Channel B) will also then be excited as the gas turbine engine is accelerated to a self-sustaining speed. The exciter controller will then switch the primary alternative designation of the channels for the next start attempt. In a start sequence in which an unsuccessful ignition event occurs, the exciter controller sets a fail-to-start on the primary ignition channel on a failure to start A/B counter such that a failed ignition channel is diagnosed without dedicated electronic diagnostic circuits while still attempting to excite both circuits to enhance the dependability of a successful engine light-off.
    • 双通道点火电路(通道A和通道B)。 在其中发生成功的点火事件的启动顺序中,励磁机控制器首先仅激励初级点火通道(通道A)。 一旦励磁机控制器识别到成功点亮,则随着燃气涡轮发动机加速到自持速度,备用通道(通道B)也将被激励。 然后,激励器控制器将切换下一次启动尝试的通道的主要替代指定。 在发生不成功的点火事件的启动顺序中,激励器控制器在启动A / B计数器的故障时在初级点火通道上设置故障启动,使得在没有专用电子诊断电路的情况下诊断故障点火通道,而 仍然试图激励两个电路,以增强成功引擎熄灭的可靠性。

    • A combustor assembly includes a combustor chamber having a primary and intermediate zone that provides for reduced flame temperatures. The combustor assembly includes first and second pluralities of injectors. The first plurality of injectors introduces fuel to a primary zone. A second plurality of injectors introduces fuel to an intermediate zone. During operation between initial start up and before the introduction of engine load, fuel is introduced into the primary zone only by the first plurality of injectors. Once engine load is applied to the engine, fuel is introduced into the intermediate zone by the second plurality of injectors. Introduction of additional volume of fuel allows the fuel-air ratio to remain constant regardless of engine operating conditions. The constant fuel-air ratio is maintained at a desired rate to lower flame temperatures and reduce nitrous oxide emissions.

    • An example gas turbine engine fuel injector nozzle assembly includes a nozzle tip secured relative to a combustion area within a gas turbine engine. The nozzle establishes a plurality of first apertures that are configured to communicate a fuel to the combustion area. The nozzle establishes at least one second aperture that is configured to communicate a fluid to the combustion area. The fluid is different than the fuel. An example method of providing fuel to a combustion area within a gas turbine engine includes communicating a fuel through a first aperture in a nozzle tip to a combustion area in a gas turbine engine. The nozzle tip establishes an axis. The method also includes influencing fuel moving from the nozzle tip using a fluid directed through a second aperture in the nozzle tip. The fluid is different than the fuel. A portion of the second aperture is radially closer to the axis than the first aperture.
