Old Timer & Warbird Propellers

Rare and no-longer-available propellers for vintage and warbird aircraft, reproduced in natural composite to fit their original hubs.

Throughout our history, we have built and serviced propellers for many iconic WWI, WWII and post-war aircraft, including the Seafire, Spitfire, Me 109, several Yak variants, Polikarpov and more.

Rare propellers, reproduced in natural composite

Thanks to the latest advances in CAD technology, combined with over 50 years of expertise in natural composite development, we can now reproduce rare or no-longer-available metal propellers for restored warbirds. Propellers such as certain Hamilton Standard, Curtiss Electric, Piaggio, PZL, VISh, Ratier and de Havilland models can now be built entirely in natural composite, ready to be installed on their original hubs with minimal modifications.

Authenticity and safety

This unique service ensures true blade authenticity, combined with outstanding safety factors and better preservation of engine and airframe.

Converting original metal blades to natural composite offers significant technical advantages:

Substantial reduction in blade weight
Lower centrifugal and gyroscopic loads on the hub and crankshaft
Reduced vibration levels
Less fatigue stress transmitted to the engine and airframe
Better handling and easier piloting, as reported by pilots experienced on these complex, powerful aircraft

The result is a lighter, smoother-running propeller that extends the service life of both engine and structure, while preserving the original historical configuration.

Current projects

We currently have several projects in progress. One of our latest developments is the exceptionally rare Fairey-Reed propeller for the de Havilland Canada DHC-1 Chipmunk. Originally a fixed-pitch metal propeller, it has been transformed by GT Propellers into a ground-adjustable natural composite design.

Like this one, many other rare propellers can be brought back to life with far fewer limitations than before. Each case is unique and must be evaluated individually: please contact us to discuss your project.

Long-term support

A dedicated database and full documentation ensure the longevity of every custom project. We provide records, spare parts and service support for many years to come.

Flying museums, maintenance facilities and warbird operators are all welcome to work with us.
