Abstract	Capabilities for designing and performing ballistic range tests at the NASA AmesResearch Center are presented. Computational tools to assist in designing anddeveloping ballisticrange models and to predict the flight characteristics of these modelsare described. A CFD code modeling two-stage gun performance is available, allowingmuzzle velocity, maximum projectile base pressure, and gun erosion to be predicted.Aerodynamic characteristics such as drag and stability can be obtained at speeds rangingfrom 0.2 km/s to 8 km/s. The composition and density of the test gas can be controlled,which allows for an assessment of Reynolds number and specific heat ratio effects underconditions that closely match those encountered during planetary entry. Pressuretransducers have been installed in the gun breech to record the time history of thepressure during launch, and pressure transducers have also been installed in the walls ofthe range to measure sonic boom effects. To illustrate the testing capabilities of theAmes ballistic ranges, an overview of some of the recent tests is given.INTRODUCTIONCurrently there are two functioning ballistic ranges at the NASA Ames Research Center.The aerodynamic range, which in'st became operational in 1965, is used to measuresteady and unsteady aerodynamic coefficients of projectiles. The gun developmentrange,radiation originallystudies. constructed in 1964, is used for gun performance enhancements and gasThe ballistic ranges at the NASA Ames Research Center has been recently renovated toprovide improved testing capabilities for research, and a number of test programs haveexploited these new capabilities. This paper presents the current ballistic range testingcapabilities at the NASA Ames Research Center. In addition to the capabilities of theballistic ranges, design tools are available that allow the entire design, testing, and data
