Technical Field
The utility model relates to a flame length detection device of a telescopic igniter, and belongs to the technical field of solid rocket engine igniter inspection.
Background
Igniters are an important component in solid rocket engines and are responsible for the precise and rapid ignition of the main engine charge. In igniter design, there are several important criteria, such as firing resistance, firing pressure, flame length and duration, which all require quantitative analysis. To a certain extent, the flame length is essentially a comprehensive reflection of the scattering capability of the high-energy ignition particles, and needs to be matched with the main charge length and the inner cavity of the engine. When the igniter works, flame is formed in the closed and long channel of the main charge, and the flame is not easy to measure. Because of the lack of testing means, the prior art still measures flame length in an open air environment, is easily interfered by wind direction or air flow, and is difficult to obtain accurate data. The method has good guiding significance for simulating the closed environment of the charging cavity as far as possible and accurately measuring the flame length to the ignition and engine charging design.
