The influence of a combustor located just upstream of a nozzle guide vane cascade on the heat flux distribution to the nozzle guide vane was experimentally investigated. The surface temperature distribution around the convectively cooled vane of the cascade was obtained by locating the cascade (1) in a low-turbulence uniform hot gas stream, (2) in a high- turbulence uniform hot gas stream, and (3) in a high-turbulence nonuniform hot gas stream just downstream of the combustor exit. The results indicate that the increased blade surface temperatures observed for the cascade placed just downstream of the combustor can be accounted for by the prevailing turbulence level measured at the cascade inlet in cold-flow conditions and the average gas temperature
