摘要
在CARDC-5的高超声速推进风洞中，采用空气作为喷流介质对双锥柱体模型的单、双喷管侧向喷流干扰进行了对比实验研究。实验状态为：马赫数6、飞行高度H=54km、迎角a=0°～6°、滚转角γ=0°～90°。实验结果表明：（1）单喷推力放大因子在1左右，力矩放大因子略小于1，喷流干扰影响较小；（2）双喷管流场因为喷流相互干扰的作用，其各放大因子变化量较单喷更稳定；（3）在此高度及模型外形条件下，不管是单喷管还是双喷管，喷流干扰对其自身推力影响不大。
Lateral jet interaction force experiments were carried out in the propulsion wind tunnel of CARDC-5 of a model equipped with divert jet thruster for single jet and double jets at a nominal flow with Mach number of 6, altitude of 54km, angles of attack ranging from 0 to 6 deg and rolling angles ranging from 0 to 90 deg. Synthesis of all the results show ： （ 1 ） both of the force and the moment of single jet are affected little by the interference; （2） the amplification factors of double jets are more stable than that of the single jet because of the interference between the two jets; （3） comparing with the force made by the jet, the interaction between air and jet are small enough to be ignored.
