Journal of Turbomachinery, 2017 Improvements in turbine design methods have resulted in the development of blade profiles with both high lift and good Reynolds lapse characteristics. An increase in aerodynamic loading of blades in the low-pressure turbine (LPT) section of aircraft gas turbine engines has the potential to reduce engine weight or increase power extraction.

Inlet total pressure loss due to acoustic wall treatment [PDF]
15th Aerospace Sciences Meeting, 1977 Experimental determination of the effect of diffuser wall acoustic treatment on inlet total pressure loss. Data were obtained by testing an inlet model with 10 different acoustically treated diffusers differing only in the design of the Helmholtz resonator acoustic treatment.

Correlation of flow path length to total pressure loss in diffuser flows
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2011 This article studies the effect of changing the flow path length on development of total pressure loss in diffuser flows. The studies incorporate quasi-one-dimensional (conical diffuser), two-dimensional (linear blade cascade), and three-dimensional (annular blade cascade) flows.

Understanding the total pressure losses nature in a Scramjet Combustor
25th AIAA International Space Planes and Hypersonic Systems and Technologies Conference, 2023The total pressure losses are of a twofold source: 1. due to high losses due to friction and shock waves as predicted by the Fanno model or 2. due to the release of heat in a supersonic stream, according to Rayleigh's law. Understanding the contribution of each of these terms is essential to improving engine performance.

Total Pressure Losses in Rotor Systems With Radial Inflow
Volume 3: Heat Transfer; Electric Power; Industrial and Cogeneration, 2000Gas turbines with a splined-disc rotor design allow the compressor bleed pressure to be adapted precisely to the requirements of rotor cooling air systems in which the cooling air is routed through the spaced between the rotating discs. Calculation of such flows is extremely difficult; particularly so if the flow is directed radially ...
