The invention discloses an aerodynamic layout and a design method of an air-breathing hypersonic aircraft with a high lift-drag ratio, and belongs to the field of aerodynamic layout design of aircrafts. A front body pre-compression face, a first-stage outer compression face, a second-stage outer compression face, a third-stage outer compression face, a stamping runner, a first exhaust nozzle and a second exhaust nozzle are arranged in the machine body/inner runner pneumatic layout from front to back, an air inlet channel splitter plate is located in the second-stage outer compression face, and a turbine runner is connected to the upper portion of the stamping runner in parallel. The aircraft has efficient high-speed cruise flight capability, meets the high lift requirement of the aircraft in a low-speed section, solves the problem of flow separation of high-speed wings in a low-speed take-off state, and can ensure the wide-speed-range flight performance of the aircraft.
