Publication number: 20240102655Abstract: A method of reducing noise from a combustor of a gas turbine engine includes the steps of establishing a maximum noise limit that may be for a particular frequency range. A primary fuel flow percentage, which may be emitted from a fuel nozzle arrangement having various groupings of simplex and duplex nozzles, is then established. An immersion depth measured between an aft rim of a swirler and a distal tip of the fuel nozzles may then be reduced thereby reducing the noise amplitude.Type: ApplicationFiled: February 3, 2023Publication date: March 28, 2024Applicant: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Justin M Locke, Dennis M Moura, Duane C McCormick, Scott A Liljenberg, Theodore R Strickland, William Proscia

Publication number: 20240098878Abstract: Direct pin-fin cooling assemblies are disclosed for a high-power printed circuit boards (PCBs). The disclosure can solve the classical coldplate problem associated with liquid cooling of high-power PCBs namely: (1) Inhomogeneous cooling due to the calorimetric heating up of the coolant, (2) thermal interface material (TIM) related quality issues such as dry-out effects, (3) high cost due to complicated metal coldplate structure, and (4) low thermal conductivity due to multi-layer structure. This includes incorporating pin-fin direct cooling into high-power PCB structures without additional coldplate structure or TIM. In this approach, a TIM and a top plate of coldplate can be removed. Thus, the cooling performance can be improved because the thermal conductivity between a liquid coolant and a power device is increased.Type: ApplicationFiled: September 16, 2022Publication date: March 21, 2024Applicant: Raytheon Technologies CorporationInventors: Yongduk Lee, Ankit Gupta, Abbas A.
