MT-Propeller produces a full line of fixed pitch, electric and hydraulic variable pitch propellers in 2 to 6 blades, constant speed, feathering and reversing.
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.
Nowadays the durable and all-weather operable variable pitch propeller blades are designed on the computer and manufactured by CNC (CAD/CAM) for highest quality and efficiency.
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. The polar moment of inertia is about half compared to aluminum blades, which means less engine loads (especially when performing aerobatics) and additionally a smooth, turbine-like run. 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.
The blade's leading edge is additionally protected by a bonded-on in the blade profile integrated stainless steel erosion sheath. We have successfully completed ice impact and simulated bird strike tests at the University of Dayton as an additional prove of the standard equipment for applications like i.e.. Piper Malibu or Mooney M20K.
The propeller hub is manufactured out of aerospace aluminum and a few out of steel. All aluminum parts are anodized and all corrosive steel parts are cadmium plated. For sea applications all external parts are additionally painted.
Spinner Assemblies and full installation kits are available in different designs and dimensions for both variable and fixed pitch propellers. Spinner domes are made out of Kevlar/fiberglass." © MT-Propeller
