DELIVERY :

Each HAUTECLAIRE propeller is delivered complete and ready to be mounted with :
- All screws

- An aluminium black anodized flange for tightening

- The digital protractor, to adapt the pitch, very precise (price = 50 € without taxes, included in the propeller's total price)
- The Instruction and Service Manual of E-Props propellers, updated version. See it here : MANUALS


 


The price of the propeller (see it on PRICES page) is including all those components.

Only a potential spinner is in option.

At E-PROPS, no need to add more expensive parts !

 

 

 

HUBS : HAUTECLAIRE 3-BLADES

 

Two types of hubs for HAUTECLAIRE propeller are available : one in carbon, the other in densified wood. Both materials are very strong. Today, the 100% carbon hub is available only for pusher configuration

 

 

1 - 100% CARBON HUB :

For engines about 50 hp, rotation sense CW or CCW, pusher configuration only (at this day)

Hub's weight = 300 gr

Hub's thickness = 75 mm

Holes = 6M8d75

RTM process : see page fabrication

2 - HUB in DENSIFIED WOOD/RESIN :

For engines about 50 hp, rotation sense CW or CCW, tractor or pusher configuration

Hub's weight = 350 gr

Hub's thickness = 60 mm

Holes = 6M8d75 (other drilling paterns possible, please contact us)

3-blades HAUTECLAIRE - hub in densified wood

 

 

Material : densified wood + epoxy resin (the wood is there as a matrix)

This material has the same mechanical characteristics as some aluminium alloys, and weights 50 percent less that aluminium.

Mechanical strength = 277 MPa [against 280 MPa for aluminium ref 2017].

It is used for example to manufacture the insolators of the raiways, because it has a high resistance in strength, a high dimensional stability, a very strong resistance to products as oil or fuel, and also a very good weather resistance.

The hub in densified wood is as strong as a carbon one.

The E-PROPS company is using this material since 2008. Those type of hubs are manufactured on a E-PROPS CNC machine.

 

=> The interests of this material against aluminium : as strong as aluminium and two time lighter, easy to manufacture, cheaper.
