초록

A gas turbine engine diffuser case construction is described that increases the amount of available discharge air for service applications compared to the prior art while reducing downstream component distortion and degradation. The diffuser case has passageways for diffused air that connect a diffused air region to a manifold. At least one orifice is located at the end of each of the passageways in the diffused air region. The size of the orifices controls the amount of air that is discharged from the diffused air region to the manifold. Diffused compre...

A method of discharging air from a gas turbine engine and of providing cooling air downstream of the discharge site, the method comprising: diffusing the compressed air in a first diffuser region so that the air has a higher static pressure relative to the compressed air; further diffusing the compressed air in a second diffuser region, further decreasing the velocity and increasing the static pressure of the compressed air; discharging the high static pressure air radially internal of and external of the annular passage flow path into a plurality of dis...
