Laminar flow control (LFC) technologies reduce heat-transfer rates as well as the weight and complexity of thermal protection system (TPS). The laminar run can be substantially increased using an ultrasonically absorptive coating (UAC). The project is focused on maturing of the UAC-LFC methodology. Key components of the effort include wind-tunnel experiments, theoretical analysis, direct numerical simulation, fabrication and testing of ceramic materials that integrate UAC and TPS functions. To aid ...
This report summarizes results of theoretical, numerical and experimental studies related to ultrasonically absorptive coatings (UAC) for laminarization of hypersonic boundary layer flow. Laminar flow control (LFC) technologies reduce heat-transfer rates as well as the weight and complexity of thermal protection system (TPS). The effort has been focused on maturing of the UAC-LFC methodology. Key components of the effort include theoretical analysis, direct numerical simulation (DNS), wind-tunnel experiments, as well ...
