Small Arms Operating Systems Animations
Explaining firing and cycling mechanisms through animated cutaway illustration.
A series of instructional cutaway animations was produced for the Light Weapon Design course, illustrating a range of firearm operating systems in which timing, sequencing, and mechanical causality are critical to understanding.
The animations make invisible forces such as pressure, mass, and energy transfer explicit, demonstrating how mechanisms unlock, cycle, and return to the battery. This approach enables a functional understanding that static diagrams and text alone cannot provide.
Based on detailed photographic and video references of fully disassembled weapons, each illustration was created as a layered technical asset with consistent framing and labelling. The final animations segment the firing cycle into clear stages, supporting safe and scalable use across classroom and online learning environments.
Simple Blowback - Operating Cycle
Cutaway animation of a simple blowback system, showing how recoil energy cycles the action without mechanical locking.
Long Recoil - Operating Cycle
Cutaway animation of a long recoil operating system, demonstrating coordinated barrel and bolt movement during firing and reloading.
Direct Impingement - Operating Cycle
Cutaway animation of a gas-operated direct impingement system, showing how propellant gases cycle the action during firing.
Advanced Primer Ignition - Operating Cycle
Cutaway illustration of an advanced primer ignition system, demonstrating how delayed pressure buildup influences bolt movement and controllability.
Delayed Blowback (Roller) - Operating Cycle
Cutaway illustration of a roller-delayed blowback system, showing how mechanical delay moderates bolt velocity during firing.
Long Stroke Gas - Operating Cycle
Cutaway illustration of a long stroke gas system, demonstrating continuous piston-driven cycling through the firing sequence.
Short Recoil - Operating Cycle
Cutaway illustration of a short-recoil operating system, showing brief barrel movement and mechanical locking during the firing cycle.
Short Stroke Gas - Operating Cycle
Cutaway illustration of a short-stroke gas system, demonstrating impulse-based piston operation and action cycling.
