Gun Systems | Intermediate
This three-day course intends to provide participants with a good understanding of firepower technologies (i.e., gun systems) in the way they work and an overview of the equipment and systems that are used in, and with guns. The course will begin with an overview of firepower technologies and then introduce participants to the way guns function, examining the physics behind operation. The course then covers aspects of recoil, installation and alternative launch approaches. This course will consist of a mixture of lectures and tutorials.
Attendees will receive a comprehensive set of notes covering the lecture content.
Who should attend?
This course is a technical course and is aimed at anyone requiring an advanced understanding of firepower technologies including (and not limited to): design engineers; material scientists; systems engineers; serving officers; and end-users. A technical background or qualification is highly recommended to get the most out of this course.

Course Learning Outcomes
At the end of this course, the student will be able to:
LO1: Explain in detail the principles of gun design and operation with respect to the materials used in construction.
LO2: Present calculations on recoil, gun droop and anticipated projectile velocities.
LO3: Articulate the physics of gun operation and firing.
LO4: Describe alternative projectile launch possibilities.
Professor Paul J Hazell
Paul has over 20 years of experience studying the impact behaviour of materials. In 2012 he 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’ (2015, CRC Press).
