In complex aerospace programmes, late discovery is often described as bad luck. It rarely is. Late discovery occurs when decisions drift, assumptions go unowned, and modelling runs without a clear decision or gate attached. The consequences are predictable. A 6–12-month delay in early industrial decisions routinely results in tens of millions in rework, supply-chain disruption, and rate-readiness pressure. Once tooling, certification evidence, and contracts are in place, even

This edition explores hybrid aerospace manufacturing, where AFP and 3D printing work in a single integrated process to create one-shot, load-path-optimised structures. The focus: moving beyond assembly, reducing joints and mass, and addressing the real bottleneck : fully coupled thermo-mechanical and crystallisation modelling for certifiable hybrid thermoplastic structures.

If you think most structural failures happen on a test flight, you're missing the real story. The trouble usually starts long before the aircraft leaves the ground. You sign off on the FEA. Margins look solid. Every load is accounted for. Then you walk onto the shop floor. Now things get interesting. Laminate thickness is off by 0.2 mm. Fibre volume fraction refuses to stick to the plan. Porosity wanders across the part like it owns the place. Cooling rates decide to experime

Trusting the numbers is the fastest way to crash an aerospace project. Sounds harsh, but it's true. Every programme I've worked on has had the same fatal flaw—overconfidence in analysis. We crunch the numbers, check the FEA, run simulations until the workstation begs for mercy. Then everyone breathes easy and ticks the box. But this is the trap. Physics-based analysis is not a crystal ball. Sure, it tells you if that wing structure will survive 2g or if the composite joint ca
