3-blade ground adjustable pitch propellers


We make 3-blade ground adjustable pitch propellers for engines 33-55 hp, diameter 140cm -163cm. You can see photos of our propellers here. Construction: blades are made of wood (oak, ash-tree and beech) and the hub is made of an aerospace aluminium alloy and is cut in mass using CNC router. Rotation can be clockwise and counter clockwise. The max speed is limited to 3000 RPM. The weight of a prop is app. 3,00 kg - 3,40 kg (depending on the diameter).

Blades are designed using special software which creates 3D models for woodworking CNC Router and are made of hardwood. The production of blades includes the following steps:

  • fabrication of  3 - 4 layers wood blocks ( using two-component wood glue D4);
  • blades are cut by multi axis CNC Router;
  • blades are precoated and grounded (the primary balancing begins during this step);
  • two coats of durable, UV and chemical resistant varnish are applied ;
  • final balancing  and application of polishing  wax.

The hub is made of Aluminium alloy 7075 T6. 7075 is as strong as many steels and has good fatigue strength. T6 temper yields the peak strength of the 7075 alloy. Its high strength-to-density ratio and light weight are desirable in aviation fields.

The standard models of our propellers are suitable for the following motors.  For other motors please contact us directly.

  • propeller for Moster 185

    We conceived a special propeller for Moster 185. The results of preformed tests showed that our propeller is compatible with this engine and insure  good cooling. During the tests we compared our propellers to propellers of some other manufactures (a Helix glass fiber prop and a Vittorazi wooden propeller for Moster 185).

    You can see the results of the tests on our youtube channel: https://www.youtube.com/channel/UCtC3m5Sj1WtbWzPaOsY7TRg
