Thermal Protection System and Thermal Management for Combined-Cycle Engine: Review and Prospects

“…Kurtz et al [137] also used tunable diode laser absorption spectroscopy as the sensor of air inlet temperature and flow field velocity (see Figure 38), pointing out that increasing the length of air inlets helps improve accuracy of the sensor. Jin [138] studied thermal parametric conversion induced by air distortion in hypersonic tests with tunable laser diode. In conclusion, the sensor with tunable diode laser absorption spectroscopy has the potential to be applied in measuring physical parameters of air inlet flow field of propulsion systems.…”

Effect of a Roughness Element on the Receptivity of a Hypersonic Boundary Layer over a Blunt Cone Due to Pulse Entropy Disturbance with a Single Frequency

“…There are many factors that affect the receptivity of the hypersonic boundary layer such as free stream disturbances, wall temperature, and roughness element. Nose-bluntness [1][2][3] and entropy-layer instability [2][3][4] also affect the flow state in the boundary layer. The factors are simply divided into the free stream disturbances and surface disturbances [5], as shown in Figure 1.…”
