| | To apply PSP in hypersonic blowdown wind tunnels, the coating has to respond rapidly to sudden pressure variations, but a reduced acquisition time is also needed, because the stagnation conditions may vary over time.... The third image, recorded seven seconds after the start of the blowdown when the stagnation conditions had stabilized, was used for the measurements.... |

| | Blowdown visualisation on the model of a Soyuz capsule... This particularly aggressive environment is reproduced in ONERA's F4 soufflerie by generating blowdowns with a duration of approximately 0.2 s. Pressures of around 1000 times atmospheric pressure are then produced and the speeds exceed 5000 m / s, i.e. 18,000 km/h.... |
