Abstract: The strand burner is a device commonly used to measure the burning rate of solid propellants, offering a simple measurement principle and easy calculation of burning rates.However, for propellants such as doublebase propellants that exhibit complex burning behavior depending on pressure, numerous tests are required.In this work, a Stojan vessel capable of obtaining the pressure-dependent burning rates of solid propellants in a single test was used to measure and analyze the burning rates of three types of propellants.For HTPB-based solid propellants, the burning rates obtained from the Stojan-vessel were slower than those measured with the strand burner, though the difference decreased as the pressure increased.In contrast, for NEPE-based solid propellants, the difference in burning rate was smaller at low pressures but relatively larger at high pressures.The pressure exponent calculated using the Stojan vessel was higher than that obtained with the strand burner. 초 록스트랜드 버너는
