Abstract : The objective of this study was to develop a method for the investigation of obscuration. A serious problem associated with artillery firings is the obscuration of the target by the cloud of smoke, dust, and debris raised by the muzzle blast. In an attempt to study this problem a development program was outlined and initiated on a model basis under laboratory conditions. A gas gun was designed and tested in conditions modeling a prototype test using flat plates as blast deflectors. The gas gun system operated satisfactorily except friction in the mechanism caused some concern. The results of the model test paralleled those of the prototype test but were consistantly lower in efficiency level. The technique shows promise and further effort development is recommended.
