Ballistic range and aerothermodynamic testing

Journal of Aircraft, 1991
Recent 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.

Ballistic Impact Testing of Composite Structures

Earth &amp; Space 2006, 2006
This 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.

The ballistic range and aerothermodynamic testing

15th Aerodynamic Testing Conference, 1988
A 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.

Fort Drum Ballistic Barrier Tests.

1996
Abstract : Experiments were conducted to determine the response of a laminated target to small arms fire. The target represented tile ceiling used to separate tile floors of a two-story building in a live fire village at Fort Drum, New York. The target consisted of 3/4-in plywood, a steel plate, a second piece of 3/4-in plywood, a second steel plate ...

Improved Ballistic Test and Evaluation Methodology

2006 IEEE Systems and Information Engineering Design Symposium, 2006
Ballistic test and evaluation of body armor is of great priority for the US Army to meet current operational needs. The current experimental design process centers on standardized threat level classifications and a baseline ballistic limit velocity, V50; both measures originate from the National Institute of Justice circa 1979. The measures are complex,

JTCG/AS Interlaboratory Ballistic Test Program

1997
Abstract : A two-phase study was conducted to determine the efficacy of MIL-STD-662E in ballistic protection limit determination for advanced lightweight armor technologies. The first-phase results demonstrated an unacceptable variability in limit estimates across sites.

A Residual Mass Ballistic Testing Method to Compare Armor Materials or Components (Residual Mass Ballistic Testing Method)

Journal of Testing and Evaluation, 2014
Abstract A statistics based ballistic test method is presented for use when comparing multiple groups of test articles of unknown relative ballistic perforation resistance. The method is intended to be more efficient than many traditional methods for research and development testing.
