Improved Nozzle Testing Techniques in Transonic Flow

Abstract

The determination of engine inlet, and nozzle performance at transonic speed is one of the most difficult experimental tasks encountered by aerodynamicists. The characteristics of the engine installation (inlet and nozzle) depend on an interaction of the engine flow and the external flow. At transonic conditions small variations of the initial flow properties approaching the boattail can produce significant effects that are difficult to predict and evaluate. In view of the importance and wide interest in the problems of nozzle testing techniques in transonic flow, a special effort is reported to develop an international program of research. The presentation of the results has been organized into two parts. The first part includes a detailed description of the experimental technique used, of the parameters investigated, and sample data from the tests conducted in each facility. The second part contains a critical analysis of the effects of the various parameters investigated.
