Outline of Final Research Achievements

Air-liquefaction cycle using in rocket engine system were integrated with the combined thermal electric power generation cycle in this study. Main objective of this study was to increase the thermal efficiency of the cycle. A new system involving solution of the cost for air-liquefaction was proposed. Mathematical model was constructed for analyzing this system and simulations were conducted. The proposed system replaces LNG fuel with liquid hydrogen. Moreover, air-liquefaction cycle is mounted using cold energy of the liquid hydrogen. The pressure ratio of the each component was optimized and we achieved 73 % of the thermal efficiency at a maximum as the combined system.
