摘要

基于轨道平台概念的旋转平衡装置已被开发用于IAR水洞。引入新的测试能力是为了在模拟器保真度增强研究中为F/ a -18飞机生成补充旋转数据库。F/A-18模型在攻角从0°到90°，无量纲旋转速率从0到/spl plusmn/0.3的稳定转捩运动中进行了测试。本文重点介绍了一种新的旋转平衡测试方法。结果的示例说明了新的旋转数据库的唯一性。与现有风洞数据的一致性总体较好。在这种飞机结构中，发现传统旋转装置中的支撑干涉效应很小。

An orbital platform rotary balance system for the IAR water tunnel

A rotary balance apparatus based on the orbital platform concept has been developed for use in the IAR Water Tunnel. The new testing capability was introduced to generate a supplementary rotary data base for the F/A-18 aircraft required in a simulator fidelity enhancement study. The F/A-18 model was tested in steady coning motion at angles of attack from 0 deg to 90 deg and non-dimensional rotation rates from 0 to /spl plusmn/0.3. The paper focuses on the new rotary balance testing methodology. Samples of the results are presented to illustrate the uniqueness of the new rotary data base. Agreement with existing wind tunnel data is generally good. Support interference effects in the conventional rotary apparatus were found to be small for this aircraft configuration.
