The design on September 27, 2022, the main requirement is to use the spherical winding composite material process to manufacture for conceptual marketing. It belongs to a design that focuses on rapid manufacturing. Therefore, in terms of product appearance, only spheres and rounded rods can be made. shape. There is no appearance or artistry.

Scheme 1 Design
The above two balls are a composite winding process, which can be quickly manufactured and is also a relatively new production process. Moreover, the winding density of the spherical composite material is low, and the light weight rocket saves fuel when in use (the density is 1.8KG/m³). Generally, rockets are made of metal with high density and heavy weight. Even aluminum is much heavier than composite materials.

Plan 2 made by oneself later (improve plan 1 for oneself)
Because I was afraid that the shape exposed alone on the top was unreliable, I added a part of fiberglass fairing in the shape of a ball and stick to the top rocket to protect the interior. (This process can only make spherical and rod-like bodies)
