Hello everybody, I've registered to the forum to ask for some guidence and this is my first message in the forum so, yeah! Recently, I've earned a government scholarship to study Aerospace and Aircraft Engineering at M.Sc. and Ph.D. level abroad (preferably UK, decided by the Ministry). I have a B.Sc. degree in Mechanical Engineering in Turkey and I've tought it would be the best to have others' thoughts and visions to help me decide which subject I'm going to study on. I've came first in the scholarship test, so I'm going to be assigned to the first choice I'll make, out of ten subjects. Which are; Aerodynamics Aeroelasticity Rotary Wing Aircraft Design Micro Air Vehicles Aircraft Electronics and Control Aeroplane Design Aircraft and Rocket Thrust Systems Aircraft and Satellite Structures Aircraft and Satellite Manufacturing Materials Orbit Mechanics I'm interested in Aerodynamics, Rotary Wing Aircraft Design and Aircraft and Rocket Thrust Systems more than others. But in every engineering branch, there are some specific subjects which trends more than others, needs more research, has more demand in the sector and academy and generally promises more for the future or has a wider work area. Can you please share your experience and vision with me for me to decide which subject would be the best for my both academic and probable private sector career after completing Ph.D.? Thanks in advance. Your ideas are so valuable for me!
