利用螺旋波电离加速并获得轴向速度约为5~10 km/s的等离子体束流,再经过电荷交换产生等速的定向高速气流。采用多束并联的工作方式模拟高速中性气流环境,实现对约0.5~3 m2的整个高超声速飞行器横截面积的覆盖,每一束气流的横截面积约为0.031 4 m2,其密度在1015~1021 m-3范围可调。基于多束并联工作原理的模拟器称之为全尺寸全空域等效模拟器,能够用于高超声速飞行器的气动力学、气动加热等的地面研究,所获得的测量数据更加符合实际飞行状态,也可以解决缩比模型实验的相似性原理差异等技术难题。
Spiral ionization acceleration is used to obtain a plasma beam with an axial velocity of about 5-10 km / s, and a constant velocity directional high-speed airflow is generated through charge exchange. The multi-beam parallel working mode is used to simulate the high-speed neutral airflow environment to cover the entire hypersonic vehicle cross-sectional area of about 0.5-3m2. Each beam has a cross-sectional area of about 0.031 4 m2 and a density of 1015 ~ 1021 m-3 adjustable range. The simulator based on the principle of multi-beam parallel operation is called the full-scale full-space equivalent simulator and can be used for ground research on aerodynamics, aerodynamic heating and the like of the hypersonic vehicle. The obtained measured data is more in line with the actual flight state, Can solve the technical problems of the similarity principle difference of scaling model experiment.
