| Abstract: | A test solid rocket ramjet with central air-inlet mode was designed,and its ignition and combustion performances were examined in the direct-connected test.The reacting flow field of the motor was numerically simulated,and the results were compared with test data.The analysis shows that the new motor structure is practicable.Compared with the low-oxygen boron propellant,the hydrocarbon low-oxygen propellant possesses higher combustion efficiency,but lower power.Numerical calculation model and method are applicable to analyzing reacting flow field of the solid rocket ramjet with central air-inlet mode. |
