ABSTRACT:
A pressure sensitive paint is applied to the surface of a measurement object main body of a wind tunnel and is irradiated with an excitation light from a luminescent sheet and excited to generate phosphorescence so that an intensity of the phosphorescence that corresponds to the pressure on the surface of the measurement object main body can be measured to determine a pressure distribution on the surface. The luminescent sheet is disposed within the measurement object main body made of a light transmitting material. The entirety of the pressure sensitive paint can be uniformly irradiated with the excitation light without applying the excitation light from a plurality of light sources disposed outside the measurement object main body, thereby enhancing the accuracy with which the pressure distribution is measured. The flexible luminescent sheet conforms to the shape of the three-dimensional curved surface of the measurement object main body.
