This paper discloses the design of a new Mach 5 civil passenger aircraft developed in the H2020 MORE&LESS Project, by exploiting the results of the previous H2020 STRATOFLY Project. To assure that the highest aerodynamic, propulsive, and operating performance are reached when approaching Mach 5 conditions, instead of the original Mach 8, a multidisciplinary methodology is developed and applied to integrate aerodynamics and propulsion aspects within a proper workflow able to generate a consistent vehicle concept meeting high-level requirements
