ExpSafe: Projectiles
iPhone / Références
**ExpSAFE Projectile Calculator Pro** is a Level 1 mobile engineering tool designed to facilitate generic projectile and primary fragmentation assessments in support of rapid safety assessments. The primary reference source for the formulae utilised in this application is the International Ammunition Technical Guides (IATG) 01.80: Formulae for Ammunition Management, with permission from UNODA.
It is noteworthy that UNODA has initiated a project called ‘UN SaferGuard.’ Their website serves as an invaluable resource for technical information and offers a comprehensive range of complimentary online tools pertaining to ammunition safety. The website introduces and summarises scientifically proven and sound formulae that can support decision-making and risk management processes.
FEATURES OF THIS VERSION
The professional edition provides the following functionality:
- Ability to calculate fragmentation initial velocities based on the gurney constant associated with selectable explosives types.
- Calculate projectile range based on simplified open source formulae.
- Determine the strike probability on a defined target (area) at a specific distance based on a multiple step process that uses Motts distribution to calculate number of fragments heavier than a reference fragment mass. Included is the option to switch between two areal density calculations in order to predict the probability of a hit.
- Calculate Hazardous Fragment Distance (HFD) aligned to munitions storage based on explosives weight and V50 velocity based on fragment shape factor and drag coefficient.
- Show the calculated fragmentation distance used by EXPLOSIM in support of training scenarios.
- Calculate generic disposal boundary distances for controlled and public areas similar to that available on the UN SaferGuard website.
- Ability to toggle between imperial and metric units for input parameters and results.
