摘　　要：使用增加发动机药量的方法,提高一室一推的火箭发动机推力时,通气参量过大直接影响发动机的燃烧性能。为此提出"两室一推"概念,发动机两个燃烧室同时燃烧产生一个工作推力平台。推力试验表明:两室一推发动机结构能有效地减小燃烧时的通气参量,同时使得发动机燃烧稳定,可以用小火箭模拟大火箭的加速度曲线。Increasing the powder quautity of the motor to enhance the thrust of single-chamber single-thrust rocket motor made the port parameter become too large, thus resulting in unstable combustion. Therefore two- chamber single-thrust rocket motor structure was put forward. The two combustion chambers of the motor com- bust simultaneously and generate one working thrust. Thrust tests show that two-chamber single-thrust rocket motor structure can effectively reduce the port parameter of the combuting motor, at the same time, make the motor combust stability. The test rocket can simulate the acceleration curve of the real rocket.
