Starting from a mixed fidelity multiple discipline analysis process for high-speed transport aircraft, a multiple discipline optimisation scenario is set-up aiming to obtain minimum weight configurations. A new, more realistic objective function driving the optimisation is implemented. A realistic flight mission for a supersonic transport aircraft (from take-off to landing) is modelled using that process. For supersonic cruise conditions -were most flight time is spent-the disciplines aerodynamics and structures are modelled at high fidelity while other contributing disciplines and flight phases are modelled less accurate. For a generic long-range mission the impact of the supersonic cruise-speed on the minimal take-off weight (enabling to cruise this long range mission) is addressed.
