SPREAD: an Engineering Tool for Preliminary Design of Hypersonic Airbreathing Vehicles

摘要

A new in-house SPREAD (Scramjet PREliminary Aerothermodynamic Design) code, which provides a preliminary design of propulsion systems, is here presented. In details, this code is able to assess performances, optimal geometric configuration, ignition delay, NOx Emission Index and influence of viscosity, once some geometric constraints and free-stream conditions were imposed.
