Survivability of a Propellant Fire inside a Simulated Military Vehicle Crew Compartment: Part 1 - Baseline Study

Crew survival in combat vehicles that carry their propelling charges and high explosive filled projectiles inside the crew compartment in the event of of an on-board explosion was examined. In a trial with simulated vehicles and instrumented simulated personnel results indicated that the thermal and ejecta threats posed the greatest risk to crew survival.

On Alternative Formulations for Linearised Miss Distance Analysis

In this report, the missile-target engagement problem is analysed. Two models commonly used for intercept engagment studies are investigated.

Small Scale Drop Tower Test for Practice Torpedo Impact Modelling

A small scale drop tower arrangement was used to simulate the dynamics of a practice torpedo impacting a submarine’s pressure hull.

Modelling Australian Red Brick and Bluestone Walls in VAPO

This provides a means of predicting the response of a building to an explosive blast load where the building is composed of Australian standard size red bricks or bluestone blocks using the Vulnerability Assessment and Protection Options (VAPO) software..

Strong Magnetic Field Characterisation

Three magnetic field sources were characterised. The sources are needed experiments investigating interactions between hot gases from a detonation and the magnetic field.

Integrated Navigation, Guidance, and Control of Missile Systems: 2-D Dynamic Models

The models developed here are suitable for both conventional and more advanced optimal intelligent guidance, particularly those based on the 'game theory' guidance techniques.

CTH Implementation of a Two-Phase Material Model With Strength: Application to Porous Materials

This report discusses improved CTH hydrocode modelling of ejecta (soil, sand etc) from detonation of buried explosive devices using two phase material model.

Establishment of a VISAR Measurement System for Material Model Validation in DSTO

The Velocity Interferometer System for Any Reflector (VISAR) is a system for recording the shock response of condensed materials. This reports on preliminary tests using the recently commissioned DSTO VISAR system, providing an assessment of the experimental set-up and accuracy of the system installation.

Precision guided weapons

Dr Barnaby Smith discusses how DST Group’s electro-optical seeker research ensures that precision missiles continue to work against new targets and countermeasures.
