Patent ID: 7024929

Claim:
An apparatus for flow testing of gas through a component having an internal gaspath, 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 internal gaspath of the component, said housing being adapted and configured to mount the component proximate to the aperture; a flow directing member located downstream of and proximate to the aperture, said flow directing member receiving gas from the internal gaspath of the component and exhausting the gas to about ambient conditions, said flow directing member including a plurality of open cells, each said cell having a plurality of walls for passage therebetween of a portion of the gas from the component; an instrument which measures a property of the gas; and wherein said housing is adapted and configured such that the internal gaspath of the component receives essentially all the gas flowing through the aperture, and said flow directing member and component define a gap therebetween such that gas exiting from the component entrains ambient air through the gap prior to entering the flow directing member.
