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.

The turbulent flame experimental device comprises a gas tank, combined plates arranged in the gas tank for separating the internal space of the gas tank, and baffles for closing the air inlet between two adjacent combined plates, each combined plate is composed of a partition plate and an arc plate which are fixedly connected as a whole, the side of the partition plate away from the arc plate is fixedly connected with the inner wall of the gas tank, the arc plates surround the combustion zone interval of the arc-shaped circular wall, the partition plate and the baffle are slidingly connected, the top and bottom of the gas tank are respectively fixedly provided with a top plate and a bottom plate, a rotating drum is movably connected in the gas tank, the rotating drum is used for blocking or connecting the air inlet and the combustion zone interval, the inside of the top plate is provided with a movable hole which is matched with the rotating drum so that the rotating drum is inserted into the gas tank through the movable hole, the rotating drum is rotatably connected with the bottom plate, the inside of the top plate is provided with a through hole which is matched with the baffle so that the baffle is inserted into the gas tank through the through hole, the top of the bottom plate is provided with a sliding groove which is matched with the baffle, and the bottom plate is provided with air holes around the periphery. The device can be used for turbulent flame test.

This utility model relates to the field of scientific exhibits, specifically a flame tornado device. The utility model includes an annular combustion pool for storing fuel and a plasma wind module arranged around the outer periphery of the annular combustion pool to generate a tornado. A sprayer is coaxially arranged inside the annular combustion pool, each sprayer including at least two nozzles evenly distributed around its axis, with the nozzles higher than the top of the annular combustion pool. The spray direction of the nozzles is radially distributed along the annular combustion pool, and each nozzle is independently controlled and used to spray flame reaction media with the same or different flame reaction colors. This utility model has a reasonable structure and diverse display effects, thereby effectively stimulating public scientific interest and ultimately achieving the effect of enlightening science.
