Design & Development

Our services

Specialized in technical challenges

As a Kaelin customer, you don’t just have access to a top-notch Design & Development department. Our specialist skills also include technical modifications to different aircraft types, historic planes and rebuilds. We produce complex CAD designs and 3D models along with the associated individual part drawings, assembly drawings and parts lists. This involves the use of a 3D scanner that also enables reverse engineering.

We devote great passion to the development and testing of individual assemblies and systems or the entire airframe. That also includes the necessary tests/experiments to verify capability for series production.

No matter how unusual a customer's request may seem, we look forward to using the latest technology and our high-performance machinery to make it a reality. We dedicate ourselves to each task with care, expertise and finesse – whether it involves current aviation requirements or individual concepts. We design, analyze, simulate, develop and produce jigs and tools, and build complete prototypes on request. 

The entire process chain is managed in-house. We provide you with everything from a single source – in a creative and flexible fashion, but always as you want it. Close collaboration with our engineering office ensures static and dynamic verification of the modifications. We do of course also assume full coordination with the aviation authorities, so that certification of the new aircraft is a smooth process.
