This report contains a current description of the Transonic Free Flight Range. This range, developed at the Ballistic Research Laboratories at Aberdeen Proving Ground for ballistic and aerodynamic research, has been in operation for approximately eight years. The accuracy and reliability of the results obtained from this range make it a valuable tool for the free flight testing of missiles and for research in compressible flow phenomena. The range, its instrumentation, and the experimental procedures associated with their use are described. The various records obtained in the range and an indication of the method employed in the reduction of the raw data into final aerodynamic coefficients are also described. In an appendix is an outline of the steps and reasoning behind the design of the Transonic Range. There is a listing of selected references to similar reports on other free flight ranges, and on the reduction, capabilities, and use of free flight range data.
