Abstract

This paper suggests an innovative sketch procedure, especially envisaged for very complex and innovative transportation systems. In order to face with the increasing complexity and innovation levels, reducing development schedule and budget, a rational approach is developed and presented. At first, high level requirements, coming from different sources are elicited and then, through a detailed impact analysis, each design parameter used to sketch the vehicle layout is connected to one or more of these requirements. Then, different semi-empirical models, exploiting available statistical data, regulations and best practices, are developed and proper sizing algorithms are suggested to provide a quantitative base to the qualitative sketching procedure. In this approach, special attention is devoted to the evaluation of the impact of the integration of main subsystems (for example, propulsion, propellant, landing gear subsystems) into the final vehicle layout. Eventually, results of the application of the described procedure to an innovative hypersonic transportation system is reported, highlighting the benefit of the increased traceability of requirements into the final product.
