The conceptual design phase of a new aircraft project is generally characterised by a large number of necessary decisions, paralleled by serious knowledge deficits, often leading to illadvised decisions which are costly and complicated to revise during later design phases. With the presented scaling methodology, a tool is provided to help increase and improve the information about the evolving aircraft project in early design stages, allowing a sounder review of presented solutions and of the design driving requirements. In an extended requirement model, performance requirements are represented along with other operational requirements. An aircraft model is introduced in sufficient detail for conceptual design considerations. The proposed computer-aided scaling methodology is explained, which, controlled by a simple optimisation module, automatically resizes the aircraft model until it satisfies the above-mentioned requirements in a minimum-mass solution. Typical results obtained at the end of the scaling are discussed together with knowledge gained along the process, and an example is given.
