Experimental Investigation of Two-Dimensional Confined Jet Thrust Vector Control

摘要

Different types of thrust vector control systems are described, and a comparison of present systems is presented. Confined jet thrust vector control is shown to be an effective alternative. A two-dimensional nozzle that operates as a confined jet thrust vector control nozzle is experimentally demonstrated. Effects of changing geometric variables and inputs on ease of vectoring and performance of vectored thrust are analyzed. Schlieren photographs and movies show flow characteristics. Predictions of performance of operable nozzles are made based on results found in the experiments. Recommendations for further study are made.
