Abstract : In the early 1960's much of the philosophy and procedures used today for captive trajectory testing was developed at the David W. Taylor Naval Ship Research and Development Center (DTNSRDC). After limited use of these procedures in the late 1960's and early 1970's, the system was inactive for several years. In the past few years, work in this area has been restarted, and several programs have been completed. The support system has been used in the captive trajectory (CTS) mode, grid mode, and pressure survey mode. Extremely good agreement has been seen for CTS data when compared with flight test results. These data have been used to guide flight test planning and to study control system acceptability. Grid data, collected on several stores, provided the means to investigate control systems and to parametrically examine other launch variables. In addition, pressure field data have been generated in support of analytical separation programs. In some cases, scale problems were encountered and have been successfully solved. (Author)
