An apparatus for providing foreign object debris protection and anti-icing capabilities to an air intake of an aircraft engine 12. The apparatus includes a frame 53 having at least a portion configured to conduct fluids. A tube 74 is positioned such that different portions of the frame 53 are fluidly connected. There is a discharge outlet 65 defined within the frame 53 that is configured to discharge fluids from the frame 53 into the air intake. An inlet 63 is defined within the frame 53 and is fluidly connected to a compressor section 39 of the aircraft engine 12. In this manner, air from the compressor section 39 of the aircraft engine 12 can flow through the inlet 63, through the tube 74, and through the discharge outlet 65, to return to the compressor section 39 of the aircraft engine 12.

The present disclosure is directed to a system 100 for monitoring an acoustic signal 104 in a gas turbine engine 10. The system 100 includes a gas turbine engine component 39 that emits the acoustic signal 104. A microphone 102 senses the acoustic signal 104 and creates a microphone signal 106 indicative of one or more characteristics of the acoustic signal 104. A controller 108 receives the microphone signal 106 and is configured to analyze the microphone signal 106 to identify a gearbox event peak. If the gearbox event peak is present, the controller 108 quantifies an amplitude of the gearbox event peak. The controller 108 compares the amplitude of the gearbox event peak to a threshold to determine whether the gas turbine engine component 39 needs maintenance.

Systems and methods (100,300,400,500) for compressing high-frequency signals are described in certain embodiments herein. According to certain embodiments, a high-frequency signal can be converted into a lower frequency signal so that it can be processed by one or more devices (120) in a lower frequency infrastructure. In certain embodiments, the high-frequency signal can be compressed by certain signal conditioning components (104) and an algorithm executed by a computer processor (304) to at least receive a high-frequency signal, correct the high-frequency signal, determine a number of samples to be taken from the high-frequency signal (i.e., sample the high-frequency signal), store a value associated with the sampled signal, and generate a waveform that includes lower frequency content that may represent the original, high-frequency signal.

The present disclosure is directed a combustor 16. The combustor 16 includes an annularly shaped liner 42 having a downstream end 60 that is rigidly connected to an aft frame 62. A flow sleeve 54 circumferentially surrounds at least a portion of the liner 42 and is radially spaced from the liner 42 to form a cooling flow annulus 56 therebetween. A plurality of fuel injector assemblies 102 is circumferentially spaced about the flow sleeve 54. Each fuel injector assembly 102 extends radially through the flow sleeve 54 and the liner 42. Each fuel injector assembly 102 is rigidly connected to the flow sleeve 54 and to the liner 42. An aft end 66 of the flow sleeve 54 terminates axially short of the aft frame 62 to form an axial gap 72 between the aft end 66 and the aft frame 62 to allow for unrestrained axial expansion and contraction of the aft end 66.


The invention relates to a water/steam system (1) for a combined cycle power plant, comprising a heat recovery steam generator (4) providing a flue gas stream path (6) for extracting heat from a flue gas stream (9) exhausted from a gas turbine, the heat recovery steam generator (4) having a low pressure section (3) including a low pressure evaporator (13) arranged along the flue gas stream path (6) for generating low pressure steam at a low pressure input level (p_(10)) for a main input (54) of a low pressure steam turbine (51). Furthermore, the invention relates to a method for operating such a water/steam system (1). In order to use heat a low temperatures, the present invention provides that in the low pressure section () additionally sub low pressure steam at a sub low pressure level (p_(11)) below the low pressure level (p_(10)) is generated by means of a sub low pressure evaporator (23) in the flue gas stream path (6).


A system (10) for regulating condensation of a flue gas (12) in a steam generator (14) is provided. The system (10) includes a temperature controller (16) and a flue gas analyzer (18). The temperature controller (16) is configured to control a temperature of a component (20, 22, 24) of the steam generator (14), the component (20, 22, 24) being in heating-contact with the flue gas (12). The flue gas analyzer (18) is configured to communicate with the temperature controller (16) and to obtain a measurement of an amount of an acid-forming compound in the flue gas (12). The temperature controller (16) adjusts the temperature of the component (10, 22, 24) based at least in part on the measurement such that the temperature of the component (20, 22, 24) is above an acid dew point of the flue gas (12) when the component (20, 22, 24) is in heating-contact with the flue gas (12).
