Abstract

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document.

The purpose of this investigation was to determine the possibility of using a semi-empirical technique, the Influence Method, to shorten the CWT supersonic flexible plate nozzle. The experiments were conducted in the CWT 8 1/2 x 11 feet flexible plate nozzle at [...] = 1.600 and [...] = 1.700.

The Influence Method and its application to shortening a flexible plate nozzle are presented and discussed. Included are comparisons of the theoretical and experimental jack influence parameters. Theoretical length estimates are presented which determine to what extent the CWT nozzle could be shortened.

Results indicate that the Influence Method can be used to shorten the CWT supersonic flexible plate nozzle. The usable testing length was increased by approximately 35% at both the Mach numbers investigated. However, as the nozzle becomes shorter the undesirable Mach number variation, in the region occupied by models, increases from [plus or minus] 0.005 to [plus or minus] 0.015.
