This project is the appearance optimization project of LAND SPACE Blue Arrow rocket launcher of domestic aerospace company. Party A has put forward more modern and more in line with the aesthetic requirements of aerospace style for the appearance of the launcher, but it must meet the requirements of reducing wind resistance under the condition of huge wind force around the launch. Under the condition that only skin knowledge of aerodynamics is stored, the plan is very headache at first, and only the feedback from the other engineers can be obtained. The overall process is evolving from a planar structure to a mesh-like strip structure. Here, I would like to share my inspiration direction.
