The goal of aircraft design is to achieve safe and efficient flight. In the world of commercial air transport, efficient, economically attractive configurations are needed. For a military fighter, extreme maneuverability, a low-observable radar signature, and cruise
performance are all important. In the second 44 years the configuration didn’t changed much, it has only matured and become more efficient. The most recent achievements that apply to this configuration concept are the Airbus A380 (Figure 2) and the ultra long range Boeing 787 (Figure 3). The BWB concept was introduced by Robert Liebeck at the McDonnel Douglas Corporation (now the Boeing Company) in 1988. The airplane concept blends the fuselage, wing, and the engines into a single lifting surface, allowing the aerodynamic efficiency to be maximized. Multidisciplinary Design Optimization (MDO) plays an important role in the design of the BWB. The high level of integration between the wing, fuselage, engines, and control surfaces inherent in the BWB design allows MDO to take advantage of the synergistic nature between the different aircraft design disciplines, resulting in an aircraft with better performance than a conventional design. So, MDO has been used extensively in the design of the BWB. A recent study at Virginia Tech 2 showed a further performance improvement of the BWB can be achieved by using distributed propulsion. The concept of distributed propulsion involves replacing a small number of large engines with a moderate number of small engines and ducting part of the engine exhaust to exit out along the trailing edge of the wing (Figure 9).
