From wind tunnel models to UAVs

Rapid, efficient, always on time

CD Aerostructures was created to offer a personal, reliable engineering design and manufacturing service.

Founded by Charles Dhenin, my extensive prototype design and manufacturing experience enables me to find solutions to complex problems before you even realise they were there.

I take pride in always being transparent, on budget, and never late.

Happy Clients

"Charles has been fantastic to work with. We’ve used CD Aerostructures to manufacture several wind tunnel models over the past year and each time it’s been very clear that Charles fully understands the requirements and goes out of his way to ensure all angles are covered for the required use case, even if we’ve missed it!"

Dr David Marshall, Wind tunnel manager, University of Southampton

Services

I work directly with all of my clients to provide a personalised service that delivers what you need, when you need. I give priority to transparency and clear communication for every project, to make sure that you have complete access to all of the information you need, and complete confidence in the work being carried out.

Wind tunnel model design and construction

CDA produces engineering test models for wind tunnel, towing tank and real world testing from start to finish, handling every element of the design and build for you, right down to the moment of the test.

UAV design, construction and flight testing

CDA offers a complete UAV design and construction service from initial idea to flight, with designs all of the higher engineering standard. Flight testing and tuning is also possible for best performance of your aircraft.
