Abstract

The potential of the joined/box-wing aircraft as an environmentally friendly airliner that is capable of meeting current and future emission thresholds led to the investigation of this concept. This study reviews the evolution and current trends in the aerodynamic design of the box-wing aircraft with specific emphasis on box-wing theory, airfoil characteristics, and aerodynamic issues of the box-wing aircraft. The study was undertaken to highlight the distinct features of the box-wing configuration which make it very attractive for future airliners. The study reveals that the box-wing aircraft possesses a significant aerodynamic advantage over conventional aircraft. The box-wing aircraft configuration is also a less radical departure from the conventional concept. It thus could be developed with existing tried-and-tested aircraft design technologies, methodologies, and processes. Hence this article is a commentary that highlights the enormous potential of the box-wing aircraft and the need for further studies in this research domain.
