壓力感測塗料(Pressure-sensitive Paint, PSP) 是一種方便、非侵入式且低成本的壓力量測技術，主要利用光致發光及氧淬滅效應量測表面壓力，有別於傳統侵入式感測器，壓力感測塗料具連續性且定量量測全域性表面壓力之能力，逐漸在風洞實驗上應用此技術。與傳統動態壓力感測器不同的是，壓力感測塗料會受到溫度變化影響使亮度改變降低測量的準確度，故須獲得表面溫度以修正數據。
本研究使用聚合物含量70%的釕錯合物PSP作為實驗塗料，並以平板、凸角流、NACA 0012及ONERA M6作為驗證PSP準確度之模型，實驗馬赫數為0.64~0.92。且利用溫度感測塗料(Temperature-sensitive Paint, TSP)量測表面溫度，並利用溫度修正in-situ(原位校正)校驗法將模型上壓力感測器量到的原始數據進行修正，獲得最終的壓力數據，並與Kulite動態壓力感測器量測之壓力數據進行比較。另外，本研究將此種塗料利用成功大學航太實驗場的震波風洞進行動態量測實驗驗證該塗料的反應時間。

Pressure sensitive paint (PSP) is used for measuring static pressure of flat plate, convex corner, NACA 0012, and ONERA M6 models with transonic test conditions (M = 0.64~0.92) in this study. The PSP we used is composed by Ru(dpp) and silica gel which polymer content is 70% and its response time is approximately 177.5 ± 33.4 μs. Because of local temperature difference, this study will apply temperature sensitive paint (TSP) to measure the global temperature distribution and then correct the error which caused by local temperature difference on PSP. In addition to this, in-situ calibration method is used in this study after temperature correction. The results are compared with the data comes from reference literature and Kulite sensors, an instrument to measure the pressure. It shows the root-mean-square error between PSP and reference data is almost ± 5% ~ 8% at Mach number is 0.64 and 0.7. The root-mean-square error is ± 8% ~ 10% at Mach number is 0.83 and 0.92.
