Abstract

An interface that provided the physical properties of the blast waves produced by free-field (FF), surface burst (SB), and height-of-burst (HOB) TNT explosions, known as AirBlast, was developed in the early 1990s and was licensed for use by more than 30 international institutions. AirBlast is no longer compatible with modern computer operating systems; however, the database of measured values of hydrostatic pressure, density, and particle velocity from more than 300 experimental explosions of TNT, with charge sizes varying from 4 kg to 500 t, is still available. This database is being used to develop new interfaces as Excel\(\copyright \) workbooks. Excel\(\copyright \) has been chosen because it is widely available, and experience has shown that its files have remained compatible with all operating systems as they have been upgraded. It is planned to develop three independent interfaces: one for FF, one for SB, and one for HOB explosions. This technical note describes the development of the FF interface that is now available for download, together with a users’ guide.
