Designing a supersonic aircraft for low sonic boom can result in some unusual features. One is a slender, asymmetrical nose to break up the bow shock into several weaker ones. Another is a long root chord on the highly swept wing, to distribute lift along the aircraft’s length. A third feature is engine inlets mounted above the fuselage and wing, to minimize their contribution to the sonic boom reaching the ground. At Glenn Research Center, NASA is conducting inlet testing on a ...
