| description | The utility model discloses a Ludwieg tube type static wind tunnel heating device, and belongs to the technical field of wind tunnel tests. The utility model discloses a static wind tunnel based on a Ludwieg tube principle. The static wind tunnel sequentially comprises a driving section, a spray tube, a test section, a double-membrane section and a vacuum tank from upstream to downstream. The wind tunnel adopts a very long driving section to store test gas of the wind tunnel, and the test gas is heated at the driving section to reach the temperature and pressure required by the operation of the test flow field. The static wind tunnel requires test gas to reduce noise as much as possible before entering the nozzle, so that the gas temperature is as uniform as possible. In order to realize gas heating in a driving section of the Ludwieg tubular static wind tunnel, the utility model provides a heating device and a control mode. According to the shape of the driving section, an electric heating mode that the heat |
