Abstract
The disclosure discloses a global pressure acquisition system for a rotating model, including a CCD camera, a signal generator, a stroboscopic pulse LED light source, a photoelectric sensor, a preset counter, and a controller. The disclosure further discloses a global pressure acquisition method for a rotating model. The disclosure has the beneficial effects that, by using the non-contact measuring method disclosed by the present disclosure, a measured model and a flow field are not damaged, a submillimeter-level spatial resolution is achieved, it is ensured that the acquired PSP image of the rotating model is clear, and the signal to noise ratio of the image is increased.
