Problems solved by technology

When it is necessary to simulate a downburst after simulating a tornado in a wind tunnel test, the tornado simulator needs to be removed and replaced with a downburst simulator, resulting in longer test intervals and complicated operations; Installing a tornado simulator and a downburst simulator at the same time will lead to an increase in investment costs
