AEROSPACE & DEFENCE

Aerospace & Defence

Innovation at altitude, compliance on the ground

The aerospace and defence sectors advance engineering under demanding safety, reliability and sustainability requirements. Organisations are improving aerodynamic performance, reducing system weight, increasing range and endurance, and modernising digital systems, all while working within strict certification frameworks and multi-tier supply chains.

At Westlock Partners, we help OEMs, tier suppliers, software integrators and MRO providers to identify qualifying R&D, prepare robust narratives, and secure funding through the UK’s innovation incentive regime. Every engagement is partner-led and technically reviewed, which keeps claims compliant and defensible while minimising internal time.

Typical Areas of R&D Activity

  • Advanced materials and lightweighting, composite structures, high-performance alloys, joining methods, surface treatments.
  • Avionics and control systems, embedded software, redundancy, sensor fusion, guidance and navigation algorithms.
  • Propulsion and thermal systems, efficiency improvements, hybrid electric, alternative fuels, heat rejection and sealing.
  • Simulation and digital twins, model fidelity, correlation with test, virtual certification and predictive maintenance.
  • Manufacturing and inspection, adaptive machining, NDT automation, yield improvement and scrap reduction.
  • Security and mission systems, secure comms, real-time processing, hardening and assurance of software components.

Common Challenges

Programmes are complex, multi-party, and tightly regulated, which makes documentation and attribution difficult. Typical hurdles include mapping uncertainty to certification objectives, separating routine qualification from genuine R&D, and capturing subcontracted work across borders while meeting territorial rules.

  • Certification alignment, evidence that uncertainty existed beyond established practice.
  • Supply chain attribution, who can claim and on which work, including subcontracting arrangements.
  • Security constraints, drafting technical narratives without disclosing restricted information.

How We Support You

  • Partner-led scoping with systems, structures and software leads, aligned to programme milestones.
  • Preparation of technical narratives and financial analysis that meet HMRC expectations for aerospace and defence.
  • Review of subcontracting and territorial considerations under the Merged RDEC scheme.
  • Comprehensive enquiry defence included as standard, with proactive evidence planning.
  • Benchmarking of claim scope and value against sector peers and current reform trends.
