Lightweight Helicopter Armament Mount Optimization
Weight on a helicopter translates directly into mission compromise. Every excess gram on an armament mount subtracts from ammunition capacity, sensor payload, or operational range. The swing-arm assembly in this case study had to endure punishing conditions: vertical G-loads during aggressive maneuvering, lateral shock from weapon recoil, and thousands of fatigue cycles in corrosive field environments. The original part, a machined steel block, met all functional requirements but carried mass that physics did not demand.
The client faced a familiar constraint matrix. Casting would require expensive tooling and weeks of lead time. Machining from billet meant material waste and geometry limited to what cutters could reach. Titanium offered weight savings but at significant cost premium. Without a way to rapidly test these trade-offs, the path of least resistance was to accept the existing design.
Using Cognitive Design, the engineering team ran topology optimization with manufacturing constraints for three processes simultaneously, evaluated 60+ variants through the Design Explorer, and delivered a 38% mass reduction with full structural validation — in under a week of engineering time.

In a documented armament mount case, the optimized stainless steel swing arm achieved a 32% mass reduction, dropping from 2.45 kg to 1.71 kg, while maintaining torsional rigidity within 2% of specification and reducing peak stress by 8%. All pivot interfaces and locking mechanism geometry were preserved throughout the optimization process.
By integrating simulation, topology optimization, and manufacturability analysis into a single parametric workflow, Cognitive Design compressed armament mount engineering from a 12-week conventional cycle to 2 weeks, an 83% lead time reduction. Parallel evaluation of material candidates and manufacturing pathways replaced sequential CAD/FEA/manufacturing review cycles entirely.
In the helicopter armament mount case, the organic self-supporting topology generated by Cognitive Design removed the need for casting dies or complex fixturing entirely, enabling rapid production of flight-ready components without capital-intensive tooling investment. This is particularly relevant for low-volume defense programs where tooling amortization across small batch sizes is economically impractical.
Cognitive Design evaluates multiple material candidates concurrently within the same generative session. For the armament mount, Ti-6Al-4V and stainless steel were compared across machining, casting, and additive manufacturing routes simultaneously, with manufacturability rules embedded from the first optimization pass. This eliminates parallel engineering tracks per material.
Yes. Cognitive Design offers on-premise deployment specifically for defense and regulated sectors where data sovereignty, export control compliance, and IP security requirements make cloud-based tools unsuitable. This ensures engineering workflows for sensitive structural and armament components remain fully within the client's secure infrastructure throughout the design process.
