The ballistic range and aerothermodynamic testing
15th Aerodynamic Testing Conference, 1988A renewed interest in hypervelocity vehicles requires an increase in our knowledge of aerothermodynamic phenomena. Tests conducted in our ground-based facilities can be used both to better understand the physics of hypervelocity flight, and to calibrate and validate computer codes designed to predict vehicle performance in the hypervelocity environment.

Ballistic Testing of Motorsport Windshields
SAE International Journal of Transportation Safety, 2013<div class="section abstract"><div class="htmlview paragraph">Since its inception in 1948, NASCAR® (National Association for Stock Car Auto Racing, Inc.) has continually strived to promote and improve driver, crew and spectator safety. As the vehicles used in NASCAR have changed over the years, their windshields have evolved also.

BALLISTIC TESTING OF SPECTACLE LENSES
American journal of optometry and archives of American Academy of Optometry, 1969ABSTRACT A ballistic method for testing spectacle lenses in safety frames is presented. Three categories of prescription spectacle lenses (industrial and dress thicknesses, tempered glass, and dress thickness allyl resin plastic), and one category of plano spectacle lenses (industrial ...

Ballistic range and aerothermodynamic testing
Journal of Aircraft, 1991Recent interest in hypervelocity vehicles requires an increase in our understanding of aerothermodyn amic phenomena. Tests conducted in ground-based facilities will be used to better our understanding of the physics of hypervelocity flight and to verify computer models that will be used to predict vehicle performance in this environment.

Abstract : The fundamentals are presented for a rational system of armor plate ballistic testing. The desirable properties of armor are first discussed. These are (1) high resistance to penetration, (2) freedom from back spalls, (3) freedom from cracking (shock failure).

Ballistic Impact Testing of Composite Structures
Earth & Space 2006, 2006This article deals with techniques which have been developed to study the behavior of composite materials and structures under high speed ballistic impact conditions at the NASA Glenn Research Center (GRC) Ballistic Impact Facility. The techniques include launching systems, fixture methods, imaging systems and instrumentation systems.

Effects of Atmospheric Turbulence on Ballistic Testing
Journal of Applied Meteorology and Climatology, 2008AbstractThe effects of atmospheric turbulence on munition target scatter are determined from numerical simulations of ballistic trajectories through many realizations of realistic simulated turbulent wind fields. A technique is evaluated for correcting for the effects of turbulence on ballistic testing procedures by using a line of sonic anemometer ...
