摘要
本文介绍在暂冲式三声速风洞中实现了非定常流动的多片光蒸汽屏显示技术和测力技术，并用这两项技术研究了亚声速时７０°后掠三角翼模型俯仰振动的非定常流动现象。
A multiminate layer vapor screen technique and force measurement technique for an unsteady flow in the intermitted wind tunnel is presented in this paper.The unsteady flow phenomena of a 70° swept delta wing pitching oscillation is investigated at subsonic speed.The correlation between the vortex structure and aerodynamic characteristics has been discussed.
