3 Year BEng(Hons) (I got in before they made it difficult to get CEng without a Masters).
I worked about 50 hrs per week for the 3 years, but I was rather more idle than some and only got a 2:2
What you describe is pretty much the Southampton "Aerospace Systems Engineering" degree, I did the "Aeronautics and Astronautics" which was more heavy metal - hence I'm now Chartered Mechanical as well as Aeronautical.
I went with A level Physics (grade A) and 2 Maths A levels (B and C) and was struggling to cope with the maths for much of the course - don't expect much repetition.
My final project was astoundingly dull and mainly to do with Metal Fatigue - what you suggest sounds far more fun. On the other hand part of my final year project got published as an undergraduate textbook so I shouldn't complain - that looked bloody good on my CV.
