Gun Design | Advanced

Course Group: 
Firepower and Protection Technologies

COURSE OVERVIEW

Building off the 2-day course, Gun Design | Introduction, this four-day course provides participants with an in-depth understanding of firepower technologies (i.e., gun systems) and an overview of the science behind the materials, systems and strategies that are used in gun design. The course will begin with an overview of firepower technologies and then examine system design, gun recoil and installation, internal and exterior ballistics and ammunition systems design. This course will consist of a mixture of lectures and tutorials.

PROFESSOR PAUL HAZELL

Paul has over 20 years of experience studying the impact behaviour of materials. He has recently moved to Canberra, Australia from the UK to take up the post of Professor of Impact Dynamics at UNSW Canberra. Before taking this position he was Head of the Centre for Ordnance Science and Technology at Cranfield University’s Shrivenham campus (at the UK Defence Academy). He has published extensively, appeared in several documentaries and presented his research work at numerous symposia. He has published two books on protection technologies with the most recent called ‘ARMOUR: Materials, Theory, and Design’ (CRC Press).
