Gun Systems *online course*
This online course provides participants with an in-depth 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 work. The course then covers aspects of recoil, installation and ammunition concepts as well as gun manufacture.
This full course comprises of 10 modules each of which correspond to approximately 3 hours of directed learning activity. Module 10 comprises of an optional online course test. Each module can be purchased individually.
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.

MODULE 6: Basic gun calculations
Calculation of barrel droop | Thick-wall pressure vessel theory | Pressure calculations | Projectile velocity calculations | The need for a recoil system | The role of the buffer and recuperator | Examples of recoil systems | Basic recoil calculations
MODULE 7: Alternative launch technologies
Cased telescopic ammunition | Segmented penetrators | Rail guns | Coil guns | Electro-thermal technologies | Light-gas guns | More on terminal ballistics with a focus on higher velocities
MODULE 8: Gun-fired projectile concepts
Types of ammunition | Penetrator materials | Fragmenting munition concepts | Mott’s fragmentation theory | Gurney theory | High-Explosive Squash-Head
MODULE 9: Fuzes and explosives
Types of fuze | Operation | Explosive types | The explosive train | Models showing the effect of explosions | Explosives in ammunition
MODULE 10: Assessment
An online test will be available for those wishing to gain post-graduate credit.
Sessions will be provided throughout the course so that the student can work through some of the issues raised under the guidance of the course presenter.
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, anticipated projectile velocities, fragment velocities and stress wave propagation and reflection.
LO3: Articulate the physics of gun operation and firing.
LO4: Describe alternative projectile launch possibilities.
LO5: Describe the issues associated with gun manufacture.
LO6: Explain the differences in penetration mechanisms for high-velocity projectiles compared to low-velocity projectiles.
Professor Paul Hazell has over 25 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).
