Flow vector analyzer for flow bench
First Claim
1. An apparatus for flow testing of gas through an arc-shaped component, comprising:
- a test bench including a source of flowing gas and a housing defining a plenum chamber and an aperture for flowing of the gas into the component, said housing being adapted and configured to mount the component proximate to the aperture; and
a measurement section located downstream of and proximate to the aperture, said measurement section including an arc-shaped inner flowpath and an arc-shaped outer flowpath for receiving therebetween the gas exiting the component, said measurement section including a measurement device between the inner flowpath and the outer flowpath, said measurement device providing a signal in response to the flow of gas proximate thereto, said measurement device being rotatable about the centerline of the arc of the component.

Abstract
Apparatus and methods for airflow testing, especially for air testing of gas turbine components on an airflow test bench. Various embodiments of the present invention include the use of a measurement section downstream of the component being tested. The measurement section, in one embodiment, includes apparatus for measurement of gas properties at a plurality of spaced-apart radial locations and/or a plurality of spaced-apart circumferential locations. In another embodiment, the invention includes a method for testing a component including a comparison of gas properties measured in both forward and reverse flow directions.
