Wind tunnel experimental research on the inlet for solid fuel ramjet assisted projectile
摘要
Abstract
The inlet is such an important component of ramjet that its performance makes an overall effect on the quality of the solid fuel ramjet assisted projectile. This paper elaborated on the performance index of the inlet for solid fuel ramjet assisted projectile and introduced the classification of the inlet for solid fuel ramjet. The emphasis of this paper is put on the introduction to the provided wind tunnel experimental result of the mixture pressure type bi-cone inlet for solid fuel ramjet of a assisted projectile when Mach number is 2. 0096, and offer detailed analysis of experimental results. When Mach number is 2. 0096, studies have shown that, within the effective range of flow section area, total-pressure recovery coefficient increases with the decrease in terms of flow section area of the inlet. In addition, total-pressure recovery coefficient decreases with increase in terms of attack angle of the ramjet assisted projectile.
