ESSAIS HELICES E-PROPS EFFET ESR

HAUTECLAIRE and ESR EFFECT

The ground adjustable HAUTECLAIRE, PROPELLER of 3rd GENERATION, provides an excellent efficiency because of a strong ESR EFFECT, which allows to obtain quite the same performances as variable pitch propellers.

Those results are validated by many TESTS CAMPAIGNS, made by the E-PROPS team and by many customers (professionals and privates).

 

 

 

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 = 75 € 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 is including all those components.

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

HAUTECLAIRE HUBS

 

 

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 3-blades pusher configuration. The 2-blades models are only in densified wood.

moyeu hauteclaire bois densifie specail wooden resin hub

2-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.
