Abstract
The application discloses a propellant combustion flame test burner and test device under rotary overload condition. The test burner comprises a burner shell, a sealing cover arranged at one end of the burner shell, a ignition connecting rod arranged on the sealing cover, a propellant grain mounting table arranged in the burner, and an observation window arranged on the sidewall of the burner. The burner and a high overload resisting image acquisition device are installed on a rotary table to form a rotary combustion test device. During the test, the rotary table is rotated to reach a required overload value, the propellant grain is ignited, the high overload resisting photographic system is started to shoot, and original images of propellant combustion flame under rotary overload condition are obtained. The application is suitable for propellant combustion characteristic test and characterization under rotary overload condition.
