I just realized aerodynamics design is my passion.

Along with a few other guys here, we are seriously planning to build a not for profit, wind tunnel in a developing country.

We already have a bunch of discarded (yet perfectly running) airplane engines and propellers, even some turboshafts.
They are in mint condition, but they must be retired from service after a set amount of flight hours for security, even if they still are almost like new.

We intend to get a free big landspace to use for free, from the local airspace authority, a university or even from the local gov't thru a technology-promoting entity.

We'll need to build the tunnel
What buildng materials can be curved? Drywall?
And some custom curved lexan windows?

For the flow conditioner to avoid turbulence maybe some plates curved to honeycomb or some thin wall tubes welded together.
