Abstract
For the past few years an extensive experimental program to understand the fluid dynamics of the Space Shuttle Main Engine hot gas manifold has been in progress at Marshall Space Flight Center (MSFC). This program includes models of the Phase II and II+ manifolds for each of the air and water flow facilities, as well as two different turbine flow paths and two simulated power levels for each manifold. All models are full scale (geometric). The water models are constructed partially of acrylic to allow flow visualization. The intent of this paper is to discuss the concept, including the test objectives, the facilities, and the models, and to summarize the data for an example configuration, including static pressure data, flow visualization, and the solution of a specific flow problem.
