ABSTRACT:
A supersonic airplane having four or two supersonic engines and one or more boost engines. During take-off and initial climb the supersonic engines are operated at a lower thrust setting within acceptable noise limits, and the subsonic engine(s) is operated to provide boost thrust to enable the airplane to operate a take-off and climb. During cruise, the subsonic engines are in a nonoperating mode, and the supersonic engines alone provide the thrust for supersonic operation. In one embodiment, one subsonic engine is deployed on one side of the fuselage during the operating mode. In a second embodiment, there are two subsonic engines deployed on opposite sides of the fuselage. In another embodiment, a single subsonic engine is installed inside the fuselage.
