Computational fluid dynamics for hypersonic airbreathing airplanes

Computational fluid dynamics (CFD) technology is discussed as it relates to the computation of flowfields associated with hypersonic air-breathing airplanes. It is shown that the unique aerodynamics of these vehicles places different demands on CFD than reentry bodies do. The major areas requiring the use of advanced CFD techniques are the prediction of airframe aerodynamics, propulsion/airframe flowfield interaction, and internal engine flows.
