Blast Fields About Rockets and Recoilless Rifles
Abstract
The report presents the results of an extensive series of measurements of the blast fields generated by firing of recoilless rifles and solid-propellant rocket motors. Peak overpressures and positive impulses are reported for blast waves in free air as well as waves reflected from plane surfaces located near the weapons and parallel to their lines of fire. Test techniques and equipment are described in some detail. Model laws are given for scaling pressures and impulses in the blast fields about recoilless rifles, and these laws corroborated by comparison with experimental results from these and previous tests. Attempts were made to generate scaling laws for prediction of blast parameters about rockets, but proved unsuccessful. Significant differences were observed in the characteristics of pressure fields generated by different rockets, and these differences are discussed in the report.
