jet noise

Analysis of turbojet and turbofan jet noise in aero engine test

涡喷、涡扇发动机试车台噪声分析

Aimed at the jet noise which is induced by the expand structure and tail tube in the resistant muffler, a finite element model at low Mach number was developed.

针对抗性消声器中扩张结构和尾管引起的射流噪声问题，建立了低马赫数射流噪声有限元分析模型。

When missiles launch from electropult, the vibration environment caused by engine jet noise measured by experiment frequently. Less foreshowing techniques are applied in this field.

箱式热发射时，发动机喷流噪声产生的振动环境多采用试验测量，环境预示手段应用较少。

Some experimental formulae about jet sound power and jet noise pressure which are contributed by the Noise Control Laboratory of The Pennsylvania State University are recommended.

接着推荐美国宾州大学噪声控制研究室关于喷流声功率与声压级的经验公式。
