SUMMARY OF THE AEROTHERMOELASTIC DEVELOPMENT PROGRAM FOR THE X-20A (DYNA-SOAR)

Abstract

This report summarizes the aerothermoelastic development status of the X-20A (Dyna-Soar) at the time the program was terminated, December 1963. Analytical and test techniques for lifting surface flutter, control surface buzz, panel flutter, and air vehicle flutter are discussed. While analysis and limited scale testing indicated a satisfactory design, necessary development testing to verify the desing had not been completed. One exception was in the area of panel flutter where high confidence existed in success. Re-entry temperatures did not appear to be a significant direct concern from the point of view of flutter. The difficulty of employing control surface dampers apparently poses a special concern for designers of reentry vehicles employing aerodynamic control surfaces.
