Passive Hypersonic Transition Control By Means Of Ultrasonically Absorptive CMC Based Thermal Protection Materials

Abstract

The proposed work builds upon a prior unrelated study conducted at DLR. Thisstudy was co-funded by the European Commission in the frame of the projectAero-Thermodynamic Loads on Lightweight Advanced Structures II (ATLLASII). This work started in 2011 and aimed to reproduce the free-stream conditionsand the wall thermal conditions found during sustained hypersonic flight. As part of this study, experimental investigations of shock wave boundary layer investigations on a at plate model at variable surface temperature were conducted.The corresponding database serves as a starting point of the proposedexperimental investigations at DLR and will be complemented with additionalexperiments in the course of the proposed project. The study proposed by DLRwill be strongly coupled with the activities in Johan Larsson s group which concentrateson the investigation of the SBLI by means of CFD. Both proposalsare complementary to each other providing the terrific opportunity to coupleexperiments and numerics to advance both in the field of SBLI. The followingwork packages are proposed.
