Internal characteristics and performance of an aerodynamically controlled, variable-discharge convergent nozzle

Jack G. McArdle
Jul 1958

The effective flow area of a convergent exhaust nozzle was reduced by injecting a high-pressure secondary jet into the nozzle near the exit. Analytical expressions relating the performance with significant design and operating variable were developed, and necessary experimental factors were evaluated by using a 4-inch-exit-diameter nozzle with unheated pressurized air discharged to the atmosphere.
