Purging flow protection of infrared telescopes

AIAA Journal, 1984
The use of a purging gas flow as a means of protecting the cryogenic optics in space infrared telescopes from condensible gaseous contaminants has been studied. The significance of both the purge/contaminant differential scattering cross section and the purge gas density distribution is analyzed.

Aerodynamic Performance of Turbine Center Frames With Purge Flows—Part I: The Influence of Turbine Purge Flow Rates

Journal of Turbomachinery, 2018
This two-part paper deals with the influence of high-pressure turbine (HPT) purge flows on the aerodynamic performance of turbine center frames (TCF). Measurements were carried out in a product-representative one and a half-stage turbine test setup. Four individual purge mass flows differing in flow rate, pressure, and temperature were injected through
