Abstract

An apparatus (38) and method for characterizing gas flow through features (22) fabricated in a hollow part (20). A pressurized gas (54) is applied t an interior of the part, and this gas pressure flows outward through features fabricated in the part. At the same time, a stabilizing pressurized gas (66) is applied to an exterior part skin (79); and the stabilizing gas has a controlled temperature differential from the gas applied to the part interior. An infrared signature of escaping gas and the surrounding part skin is analyzed by a classification method. Analysis of this infrared signature classifies the relative flow rate, size and position of the feature fabricated in the part.
