| 摘 要： | 燃烧效率能够部分反映出燃烧室性能的优劣,是超燃冲压发动机性能评价的重要指标之一。基于总温测量的超燃冲压发动机燃烧效率获取方法不需要测量或计算燃气组分、摩擦力、支板阻力等,避免了上述过程带来的误差,可有效提高测量精度。利用新型半屏式总温传感器,成功测量了M6、当量比1状态下超燃冲压发动机燃烧室的出口总温,获得了基于温升比定义的发动机燃烧效率。

| Abstract: | Combustion efficiency is one of the key parameters for scramjet performance evaluation.The combustion efficiency accuracy could be improved effectively by using the definition based on the total temperature rise and the acquired method based on the total temperature measurement,for it does not require to measure or calculate the gas components at exit of combustor,friction and strut resistance,and then avoid the errors in the course.Using semi-shielded temperature sensor,we successfully measured the total temperature of scramjet combustor exit.The corresponding flying Mach and equivalence ratio are 6 and 1 respectively.Combustion efficiency was calculated based on the total temperature rise in combustor. |
