AbstractThis paper introduces a supersonic transport aircraft design model developed in the GENUS aircraft conceptual design environment. A conceptual design model appropriate to supersonic transports with low-to-medium-fidelity methods are developed in GENUS. With this model, the authors reveal the relationship between the sonic boom signature and the lift and volume distributions and the possibility to optimise the lift distribution and volume distribution together so that they can cancel each other at some region. A new inspiring design concept—sonic boom stealth is proposed by the authors. The sonic boom stealth concept is expected to inspire the supersonic aircraft designers to design low-boom concepts through aircraft shaping and to achieve low ground impacts. A family of different classes of supersonic aircraft, including a single-seat supersonic demonstrator (0.47 psf), a 10-passenger supersonic business jet (0.90 psf) and a 50-seat supersonic airliner (1.02 psf), are designed to demonstrate the sonic boom stealth design principles. Although, there are challenges to balance the volume with packaging and control requirements, these concepts prove the feasibility of low-boom low-drag design for supersonic transports from a multidisciplinary perspective.

The trend of large-scale development of design industry requires efficient and full use of the rich design resources in the distributed multi-disciplinary resource environment. However, the designers are susceptible to many subjective and objective impacts, like knowledge structure, computing capability, geographic position, and administrative division. These impacts make the usage of design resources unstable and inefficient. Therefore, this paper proposed a computer-assisted automatic conceptual design system (CACDS). This system assumes that the design resources in the distributed multi-disciplinary resource environment exist in the form of functional elements with the same format, so that, the geographic, administrative, and disciplinary barriers in the design process can be broken, and the design resources can be fully used. CACDS is based on a group of basic concepts and their representations, its core is a functional solution generating algorithm, which is used to automatically generate functional solutions. As the result of the conceptual design, these functional solutions are also the starting point of the following detail design phase. Finally, a lighting system for underground greenhouse is designed as an illustrative case to validate the feasibility of the proposed CACDS.
