摘要

The AGARD Propulsion and Energetics Panel has sponsored an international, inter-facility comparison programme for turbine engine test facilities over the past nine years. The effort was driven by the critical nature of engine test measurements and their influence on aircraft performance predictions, ass well as the need for a sound understanding of test-related factors which may influence such measurements. The basic idea was that a nominated engine would be tested in several facilities, both ground-level adn altitude, the results then compared, the explanations sought for any observed differences. This lecture series presents the information obtained from this comprehensive program. Emphasis is given to the definition and explanation of differences in test facility measurements and to the lessons learned from this unique experiment. Partial contents: Design of the UETP (Uniform Engine Test Program) experiment; The basis for facility comparison; Investigation of factors affecting data comparison; Comparison of altitude; Comparison of ground-level test cells and ground-level to altitude test cells; Measurement uncertainty in gas turbine performance determination; Experience in developing an improved design of experiment (Lessons learned); Conclusions about facility capabilities & practices; Experience in developing an improved ground-level test capability; General test plan.
