固体火箭发动机高速旋转试验研究

高速旋转对固体火箭发动机工作性能的影响是多方面的,处于高速旋转环境中的增程固体火箭发动机工作性能预估方法是底排-火箭复合增程弹的关键技术之一.用试验的方法研究了高速旋转效应,结果表明,高速旋转将大大加快双基推进剂的燃速,不仅使推力的数值成倍增加,而且推力-时间曲线的变化规律也发生了相当大的改变.

HIGH SPEED ROTATION EXPERIMENTAL RESEARCH OF SOLID PROPELLANT ROCKET MOTOR

High speed rotation affects the performance of solid propellant rocket motor. The estimation of extend-range solid rocket motor in high speed rotation is a key technique. The high speed rotation effect is studied with experimental means, and the results indicate that high speed rotation will accelerate the combustion rate of double-base propellant, increase the thrust remarkably, and change the rule of thrust-time curve bleed.
