| Abstract | Linear and nonlinear characteristics of a dual mode scramjet combustor are investigated in ground simulated acceleration and deceleration trajectory experiments. The experiments were conducted in the direct connected transient flight trajectory simulator 1 at the Institute of Mechanics, Chinese Academy of Sciences. High frequency pressure measurements, the schlieren, and CH* chemiluminescence high speed imaging were applied for the diagnostics. Based on the quantitative analysis, the physical processes of acceleration and deceleration in general represent similar nonlinear characteristics. The linear characteristics are limited to the low frequency oscillation period in the presence of physical governing mechanisms. A nonlinear predictive model of the dual mode scramjet combustor based on historical measurements is proposed due to its generality for the acceleration and deceleration trajectory. |
