一、序言 文献[1]介绍了后掠超音速叶栅由于振动引起的非定常空气动力的计算方法,用它可预估超音速叶栅非失速颤振。文献[1]的理论也可用来计算变动来流干扰引起的作用于叶片上的非定常空气动力以及因之而产生的噪音。本文介绍其方法的概要和一些算例。 这方面,梶,岡崎和西山,小林对于直叶栅、難波对于旋转叶栅、菊地对于超音速叶栅进行了研究。菊地着重考察了前置静叶在周向倾斜时的三元影响,本文着重考 First, the preamble [1] describes the calculation method of unsteady aerodynamics caused by vibration of swept supersonic cascades, which can be used to predict the non-stall flutter of supersonic cascades. The theory of [1] can also be used to calculate the unsteady aerodynamic forces acting on the blade caused by disturbances and the resulting noise. This article describes its method overview and some examples. In this regard, 梶, Okazaki and Xishan, Kobayashi for straight cascade, Namba for rotary cascades, Kikuya for hypersonic cascades were studied. Kikuchi emphatically investigated the ternary influence of the front stator blade in the circumferential tilting, this article focuses on the test
