I'd have thought that the chemistry aspect was about covered when Otto invented his Cycle, as that is little different, Chemistry-wise in a jet. The things that do count are physics, fluid & thermo dynamics and mechanical engineering. Even single crystal metallurgy if you want to get esoteric.
Chemistry between the flight deck and the trolley dollies is a far more interesting study. (Note the applicability of Bolzmanns constant to this situation...)
Have fun!
