Fuel Nozzle Test Stand Model D39291


This test stand is designed for the purpose of testing new or overhauled APU Fuel Nozzles. Model 39291 is equipped with a 6 segment patternator that utilize pressure transducers to measure fluid volume per segment. The test is semi-automated through the test stand software to control the test start and stop points while recording test data. The test stand can be configured for a variety of segment patternators, including 12 segment as a common configuration, and come equipped with spray angle measurement capabilities.


Model 39291 incorporates a computer based data acquisition system using National Instruments hardware. Instrumentation signals including pressure, spray angle measurement, fluid flow, and fluid temperature are fed into the data acquisition hardware. A custom software program that is developed in LabVIEW® reads, displays, and reports necessary parameters to complete the test procedures.
