Test Report for the Direct Strike Lightning Test of the MCC-1 Thermal Protection System (TPS) Coated Aluminum Panels.
Abstract
This report presents the test procedures and results of the direct strike lightning effects test on the Marshall Convergent Coating -l (MCC-l) Thermal Protection System (TPS) coated aluminum frustum and aft skirt panels. The objective of this test effort was to subject the MCC-1 TPS coated frustum and aft skirt panels to the specified direct strike lightning current environment and then ascertain the structural effects of direct strike lightning on the frustum and aft skirt panels. All of the panels experienced. loss of MCC-1 TPS coating at the point of discharge due to the application of the high current (Component A) direct strike lightning environment. The amount of MCC-1 TPS coating loss varied from panel to panel and seemed to depend on how well the material was bonded to the aluminum panel. The application of the intermediate current (Competent B) and the continuing current (Component C) direct strike lightning environments resulted in a small melted spot on the aluminum panels with no additional loss of MCC-I TPS coating. The application of the restrike current (Component D) direct strike lightning environment resulted in slight blackening of the MCC-l TPS coating around the area of the discharge experienced point with, again, no additional loss of MCC-1 TPS coating.
