Pagination or Media Count:
The effects of geometric variables and temperature on the static performance of multitube suppressorejector exhaust nozzles are described and quantified. Six suppressor and four ejector parameters are investigated to establish the criteria for maximum performance. Results are presented for a model scale test of 102 related suppressorejector configurations operated at pressure ratios from 2 to 4 and at ambient and 150 F jet temperatures. Performance trends as a function of geometry are presented in a manner which allows the selection of the best geometry for any desired set of suppression and installation constraints.
