極超音速旅客機に対する複合領域最適設計と商業成立性分析

摘要

JAXA are researching and developing the hypersonic aircraft technology aiming at the practical use in 2025. This paper shows the result of MDO(Multidisciplinary Design Optimization) and commercial analysis for the HST(HyperSonic Transport aircraft) that is the goal of the hypersonic aircraft technology development. 1) The MDO estimates the lightest aircraft that can carry 100 people and fly within two hours from Tokyo to Los Angeles. 2) The statistical cost prediction method calculates the research and development price and the manufacturing price. 3) The commercial analysis estimates the price of the ticket and the aircraft for the feasible airline and manufacturing business. Through the above process, this paper shows the configuration and trajectory features of the HST and the necessary business models.
