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 d...
A supersonic airplane designed to be able to fly at supersonic speed and develop adequate thrust for supersonic flight, and yet be able to develop adequate takeoff and climb thrust to enable the airplane to take off and climb and to operate during takeoff and climb at a noise level no greater than a predetermined noise level, said airplane comprising: a. an aircraft structure capable of operating at supersonic cruise; b. supersonic engine means mounted to said aircraft structure and characterized in that said supersonic engine means is capable of generat...
