5、cility Comparison Tests RATIONALE With all the complexities of icing tunnels there are variation in results at specified environmental conditions. To be able to compare results between different tunnels, the icing community desires that the results be as standard as possible. As a first step towards

6、 a standard, a comparison of ice shapes produced at a number of icing tunnels is needed to determine the magnitude of the differences that exist between icing test facilities. TABLE OF CONTENTS 1.

SCOPE This SAE Aerospace Information Report (AIR) presents and discusses the results of tests of three models in six icing wind tunnels in North America and Europe. This testing activity was initiated by the Facility Standar

20、dization Panel of the SAE AC-9C Aircraft Icing Technology Subcommittee. The objective of the testing activity was to establish a benchmark that compared ice shapes produced by icing wind tunnels available for use by the aviation industry and to use that benchmark as a basis for dialogue between faci

21、lity owners to improve the state-of-the-art of icing wind tunnel technology. 1.1 Purpose The purpose of this AIR is to discuss the results of these tests. It documents that for any particular test-condition specifications the ice accretions produced in all of the participating facilities bore a broa

22、d resemblance to one another, but there were substantial facility-to-facility differences in ice shape and volume of accreted ice. Possible causes of the differences are discussed. 2.

INTRODUCTION Partly in response to the United States Federal Aviation Administration (FAA) Inflight Aircraft Icing Plan, the Facility Standardization Panel of the SAE AC-9C Aircraft Icing Technology Subcommittee initiated an activity involving tests of three

43、 models in various icing wind tunnels and comparison of the ice shapes produced on the models. The test results were discussed by test participants at a workshop held in August 2003 at Galaxy Scientific Corp. in New Jersey and again at a meeting of the Facility Standardization Panel held at the Ital

44、ian Aerospace Research Center (CIRA) in Capua, Italy, in October 2003. This report presents an outline of the test results and a discussion of possible reasons for some features of the results. Included in Appendix C and Appendix D are reports which were prepared for that workshop and meeting, and w

45、hich support the discussion contained in the main body of this AIR. 4. BACKGROUND Each of the major icing wind tunnel facilities in North America and Western Europe were invited to participate in the Facility Standardization activity, with a deadline of March 31, 2003, for submission of initial test

46、 results. It was agreed atearly meetings of the Facility Standardization Panel that test results would be kept anonymous so that the facility that produced any particular set of results could not be identified. Each participating facility would be identified only by a randomly assigned letter. Howev

47、er, once testing was completed and an initial review conducted, it was agreed that the facilities could be identified in the final report and the identifying letters are included in Table 1. Six facilities (designated by the randomly assigned letters A, E, F, H, M, and P) performed tests. Table 1 li

48、sts these facilities and includes icing wind tunnel parameters and information regarding instrumentation used for the tests. Three models were tested: a 36 in chord NACA 0012 airfoil at angle of attack . = 3 degrees, a 12 in chord NACA 0012 airfoil at = 3 degrees, and a 1.5 in diameter circular cyli

49、nder. The same three models were shipped from facility to facility for use in each test. Nominal test condition parameters were specified as follows: freestream air static temperature: -7, -23 and -30 C liquid water content (LWC): 0.5 and 1.0 g/m3 drop diameter (MVD): 20 and 40 m freestream airspeed: 67 and 90 m/s SAE AIR5666 Page 7 of 107 TABLE 1 - PARTICIPATING FACILITIES DATA Tu
