The fundamentals of the TSP- and PSP-techniques (temperature-sensitive paint resp. pressure-sensitive paint) have been discussed in this review. The TSP technique has been used not only to visualize surface flow features such as boundary layer transition, shocks and separation, but also to obtain quantitative surface temperature and heat transfer maps in several cases with good accuracy. Applications of the PSP technique are focused on surface pressure measurements on airfoils, generic wing-body models and aircraft models over a wide range of Mach numbers. The field mapping capability of the TSP and PSP techniques provides information about complicated flow characteristics that cannot be easily acquired using more conventional methods. Much effort has been made to improve the essential elements of the measurement system including paint formulation, illumination, imaging, and data acquisition/processing hardware and software. Currently, the development of successful TSP and PSP formulations is of fundamental importance. While no single TSP or PSP is applicable to all test conditions, a series of optimal TPSs and PSPs will be developed in the future for temperature and pressure measurements in most wind tunnels ranging from cryogenic to high enthalpy tunnels encompassing subsonic to hypersonic speeds. The capability of the measurement systems can be further extended and refined such that TSP and PSP measurements will become a routine procedure in aerodynamics testing.
