Aeronautical engineers use a __ to test aerodynamic designs. (2 Words) A A wind tunnel B B manned flight C rocket shaper D rocket tunnel

## Step 1<br />The problem is asking for the tool that aeronautical engineers use to test aerodynamic designs. The options provided are: A) wind tunnel, B) manned flight, C) rocket shaper, and D) rocket tunnel.<br /><br />## Step 2<br />A wind tunnel is a tool used by aeronautical engineers to study the effects of air moving over solid objects, such as aircraft. It allows engineers to test and refine their designs before they are built and tested in real-world conditions.<br /><br />## Step 3<br />Manned flight, rocket shaper, and rocket tunnel are not tools used for testing aerodynamic designs. Manned flight refers to the operation of aircraft with human pilots. Rocket shaper and rocket tunnel are not recognized terms in the field of aeronautical engineering.
