In M.S. thesis #1, advantages of applying exergy-based analysis and optimization methods to the synthesis/design and operation of aircraft systems is demonstrated using a supersonic aircraft fighter flown over an entire mission. A first set of optimizations involving four objectives (two energy-based and two exergy-based) are performed with only propulsion and environmental control subsystem degrees of freedom. Losses for the airframe subsystem are not incorporated into the two exergy-based objectives. ...
