介绍了底排药剂成份对底排弹减阻增程气动力性能影响的实验结果．实验采用预混合可燃气模拟真实底排药剂，改变其化学反应氧平衡系数和热值，研究了这些参数变化对底排弹减阻增程气动力性能的影响
The experimental results on the aerodynamic performance of the bottom row bomb drag reducing plus extended range are introduced. The experiment uses premixed combustible gas to simulate the real bottom agent, changes its chemical oxygen balance coefficient and calorific value, and studies the influence of these parameters on the aerodynamic performance
