The development and the design of advanced hypersonic vehicles such as the National Aerospace Plane (NASP) or the Space Shuttle will strongly depend on computer simulation mainly because some of the flight conditions experienced by these vehicles will be difficult or prohibitively expensive to create in ground facilities. Computer simulation will be used to reduce the need for expensive test time or will replace those experimental tests which can not be performed. However, computer simulations require validation before their results can be accepted. These validation tests, which must be performed in hypersonic and turbulent air flows, require the simultaneous measurement of air temperature, density and velocity at a high temporal and spatial resolution which will allow to resolve turbulence structures.
