Abstract:

Five macroscopic geometric parameters and temperature are identified as the primary variable affecting static multitube jet noise suppressor thrust performance. The a priori knowledge about each variable is discussed, and reasonable ranges of interest are established. The results of an experimental investigation, treating each variable independently, are presented. Internal performance and base ventilation values are presented and analyzed. The result of the investigation is a general static performance guide to multitube suppressor nozzles. Trends and tradeoffs are established for number, shape, length, and placement of tubes and nozzle area ratio.
