Wiedereintrittstechnologie Abschlussbericht

The ''Reentry Technology'' project, sponsored by the German Ministry for Education and Research, contains two primary points of main effort: improvement of measurement techniques in aerothermodynamics and improvement of the LBK test facility for investigations of thermal protection materials. An individual detector system with swinging mirrors for supersonic investigations has been procured and successfully used in aerothermodynamic project activities a number of years ago, but owing to the rapid technological development of these IR systems, opto-electronics, data acquisition and the analyzing software have undergone considerable improvements. For example, data acquisition in today's systems is not analog via video tapes, but digital using computers, which are faster and much more accurate. With regard to the requirements of future national and European research programs (aeronautics research program, FESTIP, etc.), therefore, a replacement by a new more efficient system became necessary, while a system of a Japanese manufacturer was selected due to the special reasons indicated. Because of its high flexibility, this system is ideally used in different wind tunnels for a variety of projects of the Main Department, including those under the DLR R and D program.
