A feasibility test for the using PSP techniques has been performed on October 2008. PSP was applied to a pylon surface of the ATTAS aircraft. In the test, three PSP measurement methods: - “intensity method with LED-array”, - “intensity method with Electro Luminescence (EL) foil”, - “lifetime method” were employed to measure pressure distributions and obtained results were compared. The results showed the good feasibility of PSP measurement in-flight test. Three methods could represent the pressure distribution on the pylon. Especially the intensity method with LED-array and EL-foil could provide results in good image quality. An EL foil which was applied to the pylon surface outside of the cabin and firstly employed in flight tests worked very well even at high altitudes. From the obtained results, one can conclude that the PSP technique successfully passed the first feasibility tests. We learned a lot of lessons from the experiences in the flight test.
