Abstract:

The present effort represents a first attempt of numerical simulation of the flow field around a complete aircraftr configuration utilizing the Reynolds average Navier-Stokes equations. The numerical solution generated for the experimental aircraft concept X24C-10D at a Mach number of 5.95 not only exhibited accurate prediction of detailed flow properties but also of the integrated aerodynamic coefficients. In addition, the present analysis demonstrated that a page structure of data collected in cyclic blocks is an efficient and viable means for processing the Navier-Stokes equations on the Cray XMP-22 computer with external memory device. Keywords Numerical methods and procedures Hypersonic research aircraft. Author
