Abstract:

Menard inserts are an effective and economical means of increasing the Mach number of an existing two-dimensional nozzle. At low Mach numbers around 1.5, increments of up to 10 percent of the basic Mach number can be achieved without loss in flow uniformity. The design of inserts for the low Mach number range can be carried out be a modified area-ratio theory. In most cases no model tests will be needed. At high Mach numbers above 2 increments in Mach number due to inserts will be less than 10 percent, and some deterioration of the uniformity of the flow must be anticipated. The design of inserts for the high Mach number regime should be substantiated by model tests, especially in the case of large increment inserts in short nozzles. Author
