Burning rate measurement with closed burner is a rapid method for measuring burning rate character and its change of solid rocket propellants in a wide pressure range. - 然而我的理解是，“混合动力”火箭引擎同时使用固体燃料和液态或气态推进剂。
However, from what I gather, "hybrid" rocket engines use both solid and liquid or gas propellants.
