Technology Programme: Aerothermodynamics and Propulsion Integration. Numericaland Experimental Aerothermodynamics

摘要

Work performed in the fields of 'aerothermodynamic predesign methods (approximatemethods)', 'numerical methods of aerothermodynamics' and 'experimental methods of aerothermodynamics' is reviewed. The objective of the work is sketched, major results are listed, examples are given and future efforts are outlined. The examples include applications of predesign methods and numerical methods for the determination of global forces and moments, aerodynamic loads and heat loads (for the latter also a study of the influence of different flow physical model assumptions). From the field of experimental aerothermodynamics, an application of a fluorescence method is given, and the picture of a wind tunnel model is shown in order to demonstrate the complexity of such test articles. At the middle of phase 1 of the technology program, basic aerothermodynamic design tools and methods are available, which will reach the first validation level at the end of phase 1. Large deficiencies in flow physical models (transition laminar-turbulent, turbulence, etc.) were identified and basics oriented and applications oriented work was initiated at universities and research establishments. Thus, work will help the second validation level, which is needed when the development of the Saenger space transportation systems begins.
