Could you use the blown plastic method to do the following?
1) Blow plastic shape based on the top profile which is based on an airfoil.
2) Layup fiberglass onto the outside of the plastic to create a female mold.
3) Construct top/bottom fairings using the female mold.
4) Blow accurate windscreens using the female mold.
5) Additional protrusions made separately using different methods.
Possible benefits.
a) Perfect symmetrical aerodynamic shape without 5 axis CNC and thousands of hours of labor of a master sculptor/$.
Possible problems.
a) Getting a 90 degree angle at the seam to prevent an undesirable ridge.
b) Contents must conform to the shape created using this method.
c) Uneven heating resulting in undesired shape
Has anyone seen some successful or failed examples of this method being used?
I have seen some examples from human powered vehicle context (which I'm making) but want to get an aero plane perspective.
