 mising compromise between the solid and liquid types\, that has not fully 
 matured yet mainly due to industry conservatism. The purpose of this work 
 was evaluation of different optimization aspects related to a hybrid syste
 m containing a volume-limited fuel grain. Thermochemical calculations were
  performed to find the “best” oxidizer-fuel combination. The H2O2-Poly
 ester combination showed the most promising results (in ρˑIsp) for volum
 e-limited systems. An optimization scheme based on a genetic algorithm was
  formulated\, developed\, and implemented in MATLAB to support the effort 
 of optimizing the whole motor for a specific mission (the Goddard Problem)
 . Three grain types were used as test cases to demonstrate the ability: th
 e Central Cylindrical Port\, the Wagon Wheel\, and the “Jagged Star”. 
 The “Jagged Star” type showed the most promising results\, but only by
  a small difference (-6% in cost function value) from more conventional de
 signs. Improvement in the models used and manufacturing capabilities (such
  as Additive Manufacturing) are key to realize optimized designs.\n Detail
