综述了测定固体推进剂燃烧稳定性的实验方法。这些方法通常基于对初始扰动的时间响应，或基于产生所需振荡的外部方法。用实验方法对冷凝相燃烧产物的尺寸分布进行了表征。“t型燃烧器”方法被证明有助于推导固体推进剂火箭发动机的压力耦合驱动贡献和颗粒阻尼。研究的其他技术包括旋转阀装置、阻抗管、调制喉声阻尼燃烧器和磁力流量计。本文认为，没有实验方法可以测量声速振荡与推进剂燃烧之间的相互作用。
An overview is presented of experimental methods for determining the combustion-stability properties of solid propellants. The methods are generally based on either the temporal response to an initial disturbance or on external methods for generating the required oscillations. The size distribution of condensed-phase combustion products are characterized by means of the experimental approaches. The 'T-burner' approach is shown to assist in the derivation of pressure-coupled driving contributions and particle damping in solid-propellant rocket motors. Other techniques examined include the rotating-valve apparatus, the impedance tube, the modulated throat-acoustic damping burner, and the magnetic flowmeter. The paper shows that experimental methods do not exist for measuring the interactions between acoustic velocity oscillations and burning propellant.
