A Quote From MT-Propeller About Their Propellers

“The blades of our variable pitch propellers are based on a proven design, which has been invented in the 30’s by a group of top engineers in Berlin, Germany and was used on many European WWII aircrafts. Over the years the original design has been improved and above all modernized.

The blade root is made out of high compressed beech wood and bolted to an aluminum ferrule with special design lag screws. The outer part of the blade body is made out of multiple laminated spruce wood, which is tapered into the high compressed wood in the carbon fiber for an increased strength and as a protection against erosion and moisture…There is also no fatigue problem and the blades are serviceable unlimited times as the dimensions do not change during an overhaul and the performance doesn’t change afterwards, either. 

Additionally our technology is very flexible in regards to update a present blade design or to develop a complete new blade design specifically for a certain aircraft or engine in a relative short amount of time as today often required for new design aircrafts or engines. Another advantage is the possibility of rebuilding propeller blades for vintage aircrafts like i.e. Focke-Wulf 190 or the Spitfire, if the original ones are no longer serviceable due to bad storage or damage.” © MT-Propeller

Additional benefits of their composite blades

Their natural composite blades are less susceptible to engine vibrations when compared to aluminum ones. so they are able to certify a new blade or prop in less time than metal blades. If they engineer a new blade design that is more efficient, a simple change to the computer program that mills the blades and they are in production within hours versus months to years to make a new aluminum blade forging. We have sold several propellers that have had some rather radical blade shapes in comparison to aluminum blades and have never had one returned due to lack of performance.

Does your MT-Propeller need servicing?

At Precision Propeller Service, we can strip down the composite blade in our shop and repair minor damage. If your blade is damaged, and we cannot repair without reducing any one of the dimensions below minimum manufacturer specifications, the propeller is not serviceable. For greater damage, the blade will be shipped to Germany with a minimum turn around time of 12 weeks. We will be able to tell you right away if we can fix it in house or if you will need to send it to Germany.
