14、Table A.1 Compilation of wind tunnel nomenclature 37 AIAA G-129-2012 vi Foreword Wind tunnel test data nomenclature may be ambiguous and is quite often a source of confusion between wind tunnel test facilities. Using a parameter incorrectly could result in bad wind tunnel data with damaging conseque
15、nces. The Ground Testing Technical Committee (GTTC) of the American Institute of Aeronautics and Astronautics (AIAA) was asked to sponsor a working group on test nomenclature. After approval, the Test Nomenclature Working Group was formed under the operating structure of the GTTC. This nomenclature
16、standard is limited to steady-state wind tunnel testing involving forces and pressures for the broader wind tunnel testing community. This guide is intended to increase the understanding of test nomenclature and axis systems between wind tunnel facilities throughout the world. Facilities should cons
17、ider fully adopting the nomenclature in this guide. At a minimum, it is recommended that this nomenclature guide be used as a reference for nomenclature between facilities. Some of the benefits that may be achieved by using a standard set of nomenclature for testing are increased customer understand
18、ing increased portability of experimental data increased usefulness of archived data increased workforce flexibility reduced data system development and support costs During the initial meeting, an invitation list was developed for prospective organizations to join the working group representing sev
19、eral wind tunnel facilities, wind tunnel customer organizations, and academia. A standard is more effective when it is accepted at inception by a broad spectrum of participating organizations. The following officers and members have provided dedicated support, contributions, and leadership to the AI
