摘要
本文简略地评述了模型自由飞、立式风洞自由飞和常规风洞自由飞这三种模拟试验方法在飞机尾旋问题研究中的作用;着重分析了开展飞机失速/偏离问题研究的重要意义以及利用现有的大型常规低速风洞进行风洞自由飞试验的必要性与可能性;对旋转天平在飞机尾旋问题研究中的作用提出了一些看法。
The role of three types of simulated methods——modelfree-flight test,vertical wind tunnel free-spinning model test andfree-flight wind tunnel model test in investigating the spin problemsof aircraft are briefly reviewed, with emphasis on the analysis of thesignificance of investigating of the stall/departure problems of aircaft,and of the necessity and possibility in utilizing the current large-scaleconventional low-speed wind tunnels to undertake free-flight wind tun-nel model tests.Some views on the role of rotary balance in studyingthe spin problems of aircraft are proposed.
