In the US subspecializations are very common and freedom is duly granted in terms of general electives:
typically the course of study would be divided as such
1. mathmatics and general physics
2. basic engineering first two years
statics dynmaics [mechanics I and II] graphics [autocad]
engineering thermodymanics elctricity and magnetism and modern physics
computer sciences
Aeronautical topics
aerodynamics[ aerodynamic principles/ stability and control/ performance/ flight envelope/ and high speed aerodynamics]
Balistics
electives from other fields
circuit analysis[I don't necessarily mean electric types]/ internal combustion engines/ strength of materials/ material sciences/ turbine science /physical chemistry......
and that gives you a BE with a concentration in aerodynamics and to become an aeronautical engineer you attend a master program for advanced electives or go to work
aeronautics well I guess that's just flying
