The ballistic performance of the bombard Mons Meg

open access: yesDefence Technology, 2016
The bombard Mons Meg, located in Edinburgh Castle, with a diameter of 19 inches (48 cm), was one of the largest calibre cannons ever built. Constructed in 1449 and presented to King James II of Scotland in 1454, Mons Meg was used in both military and ...

Analysis of pressure blips in aft-finocyl solid rocket motor [PDF]

open access: yes, 2016
Ballistic anomalies have frequently occurred during the firing of several solid rocket motors (SRMs) (Inertial Upper Stage, Space Shuttle Redesigned SRM (RSRM) and Titan IV SRM Upgrade (SRMU)), producing even relevant and unexpected variations of the SRM

Internal ballistics of smoothbore guns

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The work is devoted to the problem of the formation of a mathematical model of a smoothbore gun. It is shown that due to the low accuracy of the initial data, the high accuracy of the mathematical model is not rational, and the mathematical model in the adiabatic formulation is quite reasonable. On the other hand, simple methods
