Alternatives for the propulsion of global range transport aircraft responsive to the depletion of fossile fuels as well as to socioeconomic boundary conditions are investigated. The generation of nuclear energy on board and the remote transmission of energy by laser radiation are considered. Studies are carried out for 4 Mach number regimes and for distances of 10,000, 15,000, and 20,000 km: subsonic, supersonic, hypersonic, and a rocket glider. The concepts are subjected to a multiparametric, socioeconomic evaluation, carried out separately for the points of view of the airline, the passenger, and the environment/public. The results indicate that in the subsonic regime a nominal improvement in rank is obtained by using alternate energy sources in combination with the hydrogen-burning propfan, and with increasing ranges. The strongest effect occurs in the supersonic regime, and with increasing range. In the hypersonic regime as well as for the rocket glider, chemical concepts are the only solution.
