KK: /ˌɛəroʊdaɪˈnæmɪsɪst/
A person who studies how air moves around things, especially in relation to vehicles like cars and airplanes.
The aerodynamicist presented his findings on the effects of drag on aircraft performance.
Aerodynamicist is formed from "aero-" (from Greek "aēr", meaning air) and "dynamic" (from Greek "dynamis", meaning power or force) combined with the suffix "-ist" (meaning one who practices or is concerned with). The word refers to a person who specializes in the study of the forces and movement of air, particularly in relation to objects moving through it.
Imagine someone who studies the 'power of air' ('aero-' means air and 'dynamic' means power) — that's what an aerodynamicist does.
