Performance of Multi-fuel Hybrid Engine for Blended Wing Body Aircraft

With the air traffic growing, emissions such as CO2, NOx and noise from aviation can no longer be ignored. For this reason, the ACARE has set an ambitious objective for the year of 2050 to reduce CO2 emission by 75%, NOx emission by 90%, and noise emission by 65% in reference to the year of 2000 1. This objective will be achieved by improvement of both aero engine and aircraft. This paper presents a novel multi-fuel hybrid engine for future aircraft, namely multi-fuel blended wing body(BWB). The proposed hybrid engine has features including a hybrid combustion systems, which provides the possibility to burn two types of fuels such as LH2/ LNG and kerosene/biofuel, bleed cooling system which enables reduction of cooling air amount, thus reducing the specific fuel consumption. To study the performance characteristic of this novel concept, a zero D thermodynamic model is built. By using this model, the hybrid engine cycle parametric study has been done for cruise condition. Moreover, engine design parameters were optimized using genetic algorithms. Finally, the cruise performance of hybrid engine were compared to the baseline engine.
