Surface Pressure Measurements over a Free Flight Object in a Ballistic Range Facility using Two-Color Pressure-Sensitive Paint

Progress in Application of Pressure-Sensitive Paint Technology in Turbine Blades and Cascades

“…心熊健等 [ 1 8 ] 解决了大型暂冲式跨超声速风洞试验 中存在的诸多问题，如模型表面温度变化、光照 均匀性与强度变化、模型振动、试验数据修正、 喷涂与压敏涂料校准等，这些因素都可能影响PSP 测量结果的精准度和可靠性。测量的大飞机测压 模型和三角翼测压模型的表面压力分布图像，为 大飞机的空气动力学研究和气动优化设计提供了 宝贵的数据支撑 [17] 。日本东北大学Hirose等 [19] [20,21]…”

Dual-luminophore fast-responding pressure-sensitive paint for the simultaneous elimination of motion- and temperature-induced errors

“…These fast PSPs can achieve a frequency response beyond the kilohertz range. In recent years, PSP technology has been gradually expanded to harsher testing environments, for example, hypersonic experiments, fluttering wings, free-flight models, and fast-rotating blades [4,[8][9][10][11]. In particular, there is a pressing need for time-resolved surface pressure measurement of models with fast motion and/or large deformation, such as deformable wings and helicopter blades.…”
