| 摘 要： | 矩形喷流的红外隐身效果明显地优于轴对称喷流,矩形喷管的壁板可调,推力矢量可调的特点也已引起广泛的注意。国外早期矩形喷流的研究多限于实验,近年来在数值计算方法上取得进展[1]。国内这方面的工作未充分开展。本文在总结现有各类实验数据的基础上,给出计算等压可压矩形喷流的积分计算方法。

| Abstract: | The similarity laws of a rectangular jet are summarized on the basis of the experimental data in literature.An integration method is also presented for calculating a constant-pressure,compressible rectangular jet to examine the stealth performance of the rectangular jet.The integration method gives a good prediction of the constant-pressure rectangular jet,and the calculated results agree well with the experimental data.A brief analysis of the stealth performance of the rectangular jet is described in the paper as well. |
