Two significant technique requirements in supersonic airliner design

Supersonic airliner (SSA) is a significant development orientation for the future commercial transport. Two significant technique requirements, based on the study of the payload, range and velocity of new supersonic airliner, were deduced for SSA design. At first, a fuselage arrangement technique applicable to SSA was derived from imitating subsonic airliner fuselage arrangement method in a creative way. The demand of the passenger total to fuselage arrangement was indicated. A sample analysis shows that this technique is reasonable and available in engineering. Secondly, transforming the Breguet range equation with several relative assumptions and using weight estimate gains the relation between the takeoff weight, fuel used in mission and lift-drag radio in cruise. The requirement of SSA operating economics to the lift-drag radio in cruise was obtained. The gained two requirements have significant roles and directional value in multidisciplinary optimization design of SSA.
