| Outline of Final Research Achievements |
(1) A Lifetime (LT) PSP measurement of the areal pressure distribution on a solid wing model under a periodic up-and-down motion was developed with multiple illuminations and the signal accumulation method. (2) Furthermore, the pressure distribution on a flexible wing under a high-speed air flow of Mach 0.89 was successively and successfully imaged with the LT-PSP method. (3) An image sensor operating at the time interval of 10 ns with ten consecutive frames was developed. The sensor successfully captured "The Light-in-Flight image" for the first time in the world as an silicon image sensor. (4) A pressure measurement on a small wavy model under a low speed air flow, such as 10 m/s, was tested. The PSP intensity method captured a general tendency of the pressure distribution in the flow direction.
