Effects of Mutual Impedance on Far Field Sound Level of Rocket Strong Noise Device

CHEN Xin-huaa,ZHANG Panb,CHEN Linb(a.Dept.of Aerospace Equipment;b.Graduate School, Equipment Command Technology Academy,Beijing 101416,China)  
A computation method of mutual radiation impedance between two array elements has been established,which has been applied in the rocket strong noise device of hexagonal array.Thereby the total mutual impedance of elements on the different concentric circles in the array has been solved.It is the sum of radiation impedance of itself and the mutual radiation impedance of the other 18 elements.The mutual radiation impedance would change the exit particle velocity of the element,and it would influence the exit sound pressure of one element and the far field sound level and the pattern of the rocket strong noise device.
