Artis

At Artis, I supported R&D efforts for a novel type of Active Protection System - defeating very high-energy threats to protect armored vehicles.

Due to the sensitive nature of my work, much of it unfortunately cannot be shown... here are some snippets!

Micro 4/3 Adaptor

This adaptor was designed to connect a high speed camera body to a specific lens type. My goal with this assembly was to reduce complexity in design, assembly and use; I'm happy to say that the mounts on 6 separate cameras have held up to months of testing in high shock conditions with no failures.

Most lens adaptors simply space the lens farther from the camera body, but our design necessitated a short optical path which consequently moved the lens closer to the camera sensor. It features a bespoke captive spring pin design, optical filter retainer, and is completely sealed to prevent light ingress. Total dimensional stackup was successfully held to +/- 0.1 mm between three mated parts.

Thermal FEA

Military specifications require durability in a wide variety of environments, from deserts to tundras. Resistance to thermal stress is especially important with high-powered FPGAs, and I worked to ensure that we could accurately simulate the thermal loads in various environments. I was then able to iterate based on those simulations until my cooling solution had the required safety factor.

Shock Absorbed Test Gun

To test our systems at a lower cost and higher turnover rate, improvements to our shock absorption system needed to be made. The front and rear barrel carriages run on linear rails, ensuring high stability and repeatability. Combined with a rigidly mounted scope, this redesign allowed me to land shots within a 100mm radius over a 500m range.

Each carriage section was designed with lifting eyes for easy installation and a self-contained section that could be aligned to the barrel travel

Posing with my "kill"... the first sighting-in shot was a bit further off target than expected!
