Abstract:

In this project, ARDEC completed the development and testing of a 155-mm gas gun ballistic simulation system initially designed and constructed by Frankford Arsenal. The goal of the project was to provide a cost effective alternate to live explosive gun firings through simulation of high-g impulse shock in a laboratory environment. The two tasks were 1 development of a lightweight digital memory module DMM that would operate in high-g ballistic shock environment, and 2 establishment and documentation of the characteristics of the gas gun simulator with the DMM. A multichannel DMM using basic digital design, implemented by state-of-the-art electronic components, was successfully developed. The newly developed DMM was used to acquire setback and tangential acceleration data for more than 50 test firings. The performance characteristics and range acceleration amplitude and duration of the simulator as a function of extremes in metering hole patterns was established. The acceleration amplitudes and durations generated by the simulator can be varied within its operational range to provide good simulations of gun fire shock parameters which are not otherwise reproducible in a laboratory facility. The order of magnitude increase in duration over diaphragm-type air guns, plus its spin capability, makes the simulator useful for a variety of applications in which conventional diaphragm-type air guns are unsatisfactory.
