LEADING EDGES DEVELOPMENT - DYNA SOAR
Abstract
This document reports on the facilities development and test results from the Dyna Soar Leading Edge Development Program. The leading edge development program was undertaken: (1) to evaluate experimentally five leading edge and attachment scheme designs proposed for use on the glider and (2) to establish the reliability and structural integrity of the most promising design. All designs tested were evolved from the thin shell, coated molybdenum alloy leading edge concept which was proved feasible during Phase I of the Dyna Soar program. All tested leading edge designs performed satisfactorily from the strength standpoint. No structural failures were caused by sonic testing, thermal stresses resulting from thermal gradients and heating rates, or plasma testing of the double shell design. All designs supported significantly higher loads than predicted during static tests. Although oxidation failures occurred through the molybdenum disilicide coatings during the radiant heat and plasma jet tests, the extent of these failures did not prevent the specimens from meeting the design requirements.
