日本宇宙航空研究开发机构（JAXA）为其大型工业风洞建造了实用压敏涂料（PSP）测量系统。介绍了该系统的组成和应用试验情况。介绍了该系统的主要内容，包括PSP涂料、压力计算方法和压力计算装置。介绍了一种高精度的压力计算方法--先验/原位混合法，并将其应用于数据处理。为了验证该PSP系统，使用ONERA M5标准模型在跨音速风洞中进行了实验。PSP结果代表了全球定量压力分布。与测压口相比，系统的PSP数据精度2σ为1.9 kPa（M = 0.84时Cp = 0.06）。然后，将JAXA实用PSP测量系统应用于日本支线喷气机研制试验。其结果也代表了一个详细的和整体的流动结构的测试模型。巡航状态下PSP数据的2σ为Cp = 0.06。结果表明，该系统可用于大型工业跨声速风洞的实际试验。
Japan Aerospace Exploration Agency (JAXA) has constructed the JAXA practical pressure-sensitive paint (PSP) measurement system for their large industrial wind tunnels. Its system and application tests were introduced. Contents of the system which included PSP paint, pressure calculation method and apparatus were described. A high accuracy pressure calculation method, a priori/in situ hybrid method, was also introduced and applied to the data processing. For validating this PSP system, an experiment using an ONERA M5 standard model was conducted in a transonic wind tunnel. PSP results represented global quantitative pressure distribution. The PSP data accuracy, 2σ, of the system compared with pressure taps was 1.9 kPa (Cp = 0.06 at M = 0.84). Then, the JAXA practical PSP measurement system was applied to the Japanese regional jet development test. Its results also represented a detailed and global flow structure on the test model. 2σ of PSP data was Cp = 0.06 at cruising condition. It was proved that the present PSP system could be applied to practical tests at a large industrial transonic wind tunnel.
