Typical Mortar Recoil Forces Produced When Firing Spherical Aerial Shells

(Included in the text of this article are a series of notes. These notes present ancillary information that may be of interest to some readers but are not strictly needed within the context of this article. Thus readers should feel free to ignore the notes unless they desire more information.) One of the more common requests for information regards the recoil force produced when aerial shells are fired from mortars. Generally the concern is whether some support structure (e.g., roof top, platform or barge deck) will safely accommodate the dynamic load produced as shells of various sizes are fired from mortars placed upon the support structure. Providing a precise answer can be a complex engineering problem, requiring information that is not readily available. However, providing reasonable estimates for the recoil forces produced by the firing of typically performing aerial shells is a relatively easy matter. This article provides those approximate values for typical 3- through 12- inch (75- through 300-mm) spherical aerial shell firings. (These values are only for single break spherical shells; they are not for cylindrical shells or for so-called stacked, double-bubble, or peanut spherical shells.)
