5、space Research Document) status and was formerly catalogued as ARD500026. Most of the report is unchanged since the material is as useful now as it was when first published in 1995. A few paragraphs have been updated to reflect knowledge gained on recent aircraft programs. Other changes reflect cons

6、istency with more recently adopted definitions, and minor editorial and typographical corrections. However in the course of this upgrade, it became apparent that the original figures were no longer available nor were the means to recreate them. In some cases, figures have been redrawn. For the remai

7、ning figures (and tables), the best available copy was scanned. The committee apologizes for any lack of clarity produced by this procedure. FOREWORD As applications for turbine engines have become more sophisticated and the operating conditions more severe, inlet planar time-variant full-face total

8、-pressure variations, usually accompanied by spatial total pressure distortion, can become a significant destabilizing factor. The SAE S-16 Turbine Engine Inlet Flow Distortion Committee has recognized the need for guidelines and procedures that would address inlet planar waves and the desirability

9、of documentation similar to SAE documents ARP1420 and AIR1419 that were written for inlet spatial total-pressure distortion. This Aerospace Information Report (AIR) brings together information and ideas that are required to address the planar wave problem. A common industry practice has yet to be es

SCOPE “An Assessment of Planar Waves” provides background on some o

24、f the history of planar waves, which are time-dependent variations of inlet recovery, as well as establishing a hierarchy for categorizing various types of planar waves. It further identifies approaches for establishing compression-component and engine sensitivities to planar waves, and methods for

25、accounting for the destabilizing effects of planar waves. This document contains an extensive list and categorization (see Appendix A) of references to aid both the newcomer and the practitioner on this subject. The committee acknowledges that this document addresses only the impact of planar waves

26、on compression-component stability and does not address the impact of planar waves on augmenter rumble, engine structural issues, and/or pilot discomfort. 2.
