AbstractAn early supersonic cruise vehicle conceptual study in 1969 identified a number of configuration, stability and control, and performance problems. Continuing research has provided solutions to many of these problems, which were essentially aerodynamic in nature. This article presents a multi-discipline approach to the application of the latest technology to supersonic cruise aircraft concept definition, identifies current problem areas and cites developing technology, in several disciplines, which are prospective solutions to these problems. Approach, status and potential for improvement are addressed through consideration of a Langley Research Center (LRC) concepted supersonic cruise configuration (based on technology developed since 1969) and several parametric variations. As part of the developing technology, a recently developed aircraft sizing and performance computer program now makes possible rapid analysis of the effects of configuration resizing such as changes in wing loading and thrust-to-weight ratio. This program was used to determine allowable wing loading and takeoff gross weight sensitivity to structural weight reduction. Structural weight reduction as large as 15%, or more, appears highly probable in light of recent technology advances with fiber reinforced composites or other advanced structural techniques. Based on scale model tests of coannular nozzles, noise suppression on the order of that required for the configurations considered here can be achieved.
