    Abstract: An embodiment of the present invention is a gas turbine engine including a compressor, a turbine, an annular combustor, an exhaust duct, a first engine shaft bearing, and a second engine shaft bearing. The turbine has an axial flow direction toward the compressor. The combustor has an axial flow direction away from the compressor. The exhaust duct is disposed between the compressor and the combustor. The first engine shaft bearing is disposed on an axial side of the compressor opposite the turbine. The second engine shaft bearing is disposed on an axial side of the turbine opposite the compressor.

    Abstract: A system for light-off detection in a gas turbine engine (20) according to an example of the present disclosure includes, among other things, a computing device that has memory and a processor. The computing device is configured to execute a data module (174) and a comparison module (176). The data module (174) is programmed to access data that corresponds to a present rotational speed of a gas turbine engine component. The comparison module is programmed to cause an indicator (188) to be generated in response to determining that an acceleration rate relating to the present rotational speed meets at least one predetermined acceleration threshold, the indicator relating to an engine light-off condition.

    Abstract: Methods and systems for a gas turbine engine (100; 200) comprising a modulated bleed valve (360) are provided. The gas turbine engine (100; 200; 400) may comprise a turbine nozzle (285) coupled to a controller (350), a modulated bleed valve (360) in communication with the controller (350), and a tangible, non-transitory memory providing instructions to the controller (350) to perform operations. The operations may include receiving parameter values (371, 372, 373) from the parameter sensor (370) at various times, determining desired bleed airflows to flow through the modulated bleed valve (360) at various times, and/or commanding the modulated bleed valve (360) to assume an open configuration or a closed configuration at various times. The modulated bleed valve (360) may be configured to allow bleed airflow (340) to bypass a nozzle choke area (286; 386) of the turbine nozzle (285) and join a nozzle airflow (225; 325).
