Access to high-calibre capability – without the overheads

Large OEMs can call on decades of institutional knowledge and deep specialist benches whenever a difficult problem arises. Independent OEMs, STC holders and emerging programmes rarely have that luxury. They need the same calibre of engineering judgement – but without the cost of building and retaining a permanent department for capability they may need only periodically.

This is where Stirling Dynamics operates. Our engineers have built their expertise on programmes for Airbus, BAE Systems and other leading manufacturers, working across some of the most demanding certification and design challenges in the industry. We now bring that same capability to bear for smaller, independent organisations that need it just as much but don’t have the resources in-house.

We work as a genuine extension of your team: we work with clients globally, so wherever you are located we can deliver successfully regardless of your location. Distance is rarely a barrier to working together.

Demand

Why independent engineering support is in demand

Three forces are driving the need for independent specialist consultancy across aerospace and marine:

Flexible specialist resource

OEMs and suppliers want to flex specialist resource up and down without adding permanent headcount. Certification pushes, design reviews and technical investigations are rarely constant workloads. Bringing in the right expertise for the duration of the requirement – and no longer – is a far more efficient way to resource difficult engineering challenges.

Ageing platforms and legacy programmes

Ageing platforms and legacy programmes continue to need engineering support long after the original design teams have moved on or dispersed. Continued airworthiness, obsolescence management and modification work on older platforms demand engineers who understand both the original design intent and current certification expectations.

CVE support

CVE support, particularly for STC holders that don’t have the in-house compliance expertise to keep a modification programme moving. Our Compliance Verification Engineers provide the independent oversight needed to demonstrate that a design meets the applicable certification requirements, working across the compliance documentation, substantiation evidence and showing of compliance that regulators expect to see. This is often the difference between a modification programme progressing smoothly through certification and one that stalls waiting for the right technical sign-off. Clients bring us in either to support a specific STC application from the outset or to review and strengthen an existing compliance package before submission.

Innovative solutions

We have an agile and innovative mindset, bringing ideas from different disciplines. Drawing on our experience across multiple industries and disciplines enables cross-pollination of ideas to bring unique solutions.

Engineering services across the full design and certification lifecycle

Our specialist engineering capability spans the following disciplines – each delivered by engineers with direct experience on large commercial and defence programmes.

Aeroelastics

Aeroelastics forms a core part of our offering. We build the digital models and carry out the calculations and full analysis required to determine loads on the airframe for design purposes (covering wings, aerodynamic surfaces and fuselage structures).

Mathematical modelling

Mathematical modelling for multi-domain systems such as hydraulics, avionics, navigation, landing gear, tilt rotors, submarine ballast and hydroplanes. This capability is particularly valuable for organisations developing novel platforms and disruptive technologies across the aerospace and marine sectors, where modelling helps to inform design decisions while requirements, system architectures and operational concepts are still being defined.

Systems integration

Systems integration and update work draws on experience gained across many different aircraft and platforms from legacy to the latest generation. Our engineers have supported integration of new systems into established airframe architectures.

Safety analysis

Safety analysis identifies what can cause a system or component to fail and classifies those failures against the relevant certification requirements, forming the technical foundation for safety cases and compliance arguments.

Stress analysis

Stress analysis covers airframes and equipment including wheels, landing gear, actuators and hydraulic systems, establishing the structural substantiation needed to support design and certification decisions.

CVE support

CVE support helps STC holders to navigate compliance requirements, providing the independent technical oversight needed to keep modification programmes moving through certification.

Mechanical design

Mechanical design is reserved for problems that genuinely require a bespoke solution rather than an off-the-shelf answer. Recent examples include tilt-rotor mechanisms, hydraulic equipment for flight controls and landing gear systems – all developed from first principles to meet a specific operational requirement.

Software and electronics

Software and electronics capability sits alongside our mechanical design work, typically at equipment level. This includes controllers, sensor technology, data acquisition and processing, motors for flight control surface actuation, rotating systems such as those found in tilt-rotor applications, and fin actuators for missile guidance systems.

Marine engineering support

Marine engineering support, drawing on the same underlying disciplines, is focused principally on safety analysis system modelling, and vehicle and local control development for marine platforms and systems.
Independence

Your trusted, independent partner

Clients come to Stirling Dynamics because they need an independent perspective, backed by engineering judgement that has been tested on some of the most demanding programmes in the industry. We are not tied to a particular design philosophy or legacy solution, which means we bring genuinely independent thinking to every problem we’re asked to solve.

We take the protection of client intellectual property extremely seriously. Every engagement is governed by strict NDA protocols, and we operate with the same discipline around confidentiality that we would expect from a partner working on our own IP. At the same time, we are happy to share our own accumulated knowledge and methods with clients where it helps them to build their own capability and develop their own IP. Our aim is a genuine partnership, not a transaction.

Example Programme

Boeing 757 flying testbed conversion

Our specialist engineering team has been supporting the conversion of a Boeing 757 into a flying testbed, a programme requiring a substantial nose cone extension and a series of fuselage fairings, blisters and radomes to house specialist sensor equipment. Work of this nature calls on structural, aeroelastic, modelling and systems integration expertise in combination, precisely the kind of multidisciplinary engineering challenge our specialist consultancy service is built to address.
