GAMBOA-CASTELLANOS, Ricardo Alberto; CARRILLO-BAEZA, José Gonzalo  y  FLORES-JOHNSON, Emmanuel Alejandro. Design and Construction of a One-Stage Gas Gun for High Velocity Impact Tests. Ing. invest. y tecnol. [online]. 2015, vol.16, n.2, pp.185-195. ISSN 2594-0732.

High impact tests are characterized by a projectile traveling at high speed as well as complex events such as flying fragments due to the velocity at which the impact occurs; however, these tests have become increasingly popular due to need for more stringent protective material requirements nowadays. In this paper, the design and construction of a one-stage light gas gun for ballistic testing is presented. This particular design is characterized by its simplicity, excellent performance at low cost and compact dimensions, when compared to commercial systems, presenting an affordable option for materials characterization for high velocity impact tests. The results are completed with the characterization of an armor grade material, obtaining the ballistic limit of the material, as well as demonstrating the effectiveness and versatility of the equipment.
