A multidisciplinary optimization (MDO) methodology for the design of vacuum nozzles is
presented, based on the maximization of the total stage or vehicle velocity increment.
Traditional design methodologies for vacuum nozzles are discussed and compared to an
MDO-based approach which accounts for the size and mass of the nozzle as well as
multidisciplinary performance trades. Various levels of analytical fidelity are discussed with
respect to physical accuracy and computational cost. The method is tested in an example of
CH4-LOX nozzle and the results compared to the results of a traditional method. Finally,
future directions and the use of higher-fidelity analytical tools are discussed.
