水素燃料超音速旅客機の機体成立性に関する研究

抄録

Recently, environmental problems have been paid great attention in the world. According to the current report of ICAO, CO₂ emissions of aircraft to the total emissions will increase at an average annual rate of 3∼4%. Furthermore, stable supply of oil is becoming difficult. Without exceptions, those are hitting aviation industries. Therefore, in the near future, the time to shift from kerosene to liquid hydrogen (LH₂) as fuel of aircraft will come. An idea of supersonic transport (SST) fueled by LH₂ as one of the next-generation SST has been proposed by JAXA. The purpose of this study is to compare the weight, aerodynamics and cost of hydrogen fueled SST with those of kerosene fueled SST and to discuss its feasibilities. A possibility of two-bubble fuselage configuration is also evaluated.
