E-PROPS REPAIR / SPARE BLADES

The E-PROPS propellers are very strong => E-PROPS : the strongest propellers

All E-PROPS models have a leading edge protection in Nanostrength® => Leading edge protection

 

When propellers are rotating, they can hit some objects, equipements, stones, or even the ground... In light aviation, the propellers have a max rotation speed at tips between 0,50 and 0,75 Mach, it means between about 600 and 900 km/h. At those speeds, a very small impact may have very important consequences on the blades.

 

---------------

 

Many impacts are minor, and can be easily repaired.

 

The E-PROPS propellers are made in 100% carbon braid. This process is named HCF : Helical Continuous Fibers. It is specifically designed by E-PROPS, ensures an exceptional strength of the 100% carbon + epoxy resin blade, from leading edge to trailing edge, from blade's foot to tip.

 

To the contrary of the usual process called half-shell, used by most of the manufacturers of composite propellers, the carbon fibers are continuous between the top and bottom surfaces. The braid is made like a sock. The mechanical strength is increased and becomes very high : no risk of rupture by delamination of the leading edge, no craks on the blades or on the hub.

Examples of damage :

 

repair eprops

the tips can be easily repaired, localised impacts too.

A proper cut and / or a repair kit may be enough for those small repairs

Be careful with the balancing to avoid vibrations.

When the foam core (colored) is apparent, the repair is no more possible : the blade has to be changed

 

 

If only one blade is damaged :

At E-PROPS, it is possible to change only one blade. With the serial number, our team will find its technical file, and can make a new blade, well-balanced with the remaining good blade.

 

Traceability is essential for E-PROPS.

A RFID chip is in each blade is inserted in each blade, with all technical data inside : manufacturing date, detailed monitoring (braid batch, epoxy resin batch, additives...), names of the workers, measures (temperatures, pressures) and weights all along the manufacturing process, finish, commercial file.

 

 

*** On the PLUG'n'FLY models, each blade has :

- a reference number of the propeller number (4 letters and numbers) : example => P601, G74R...

- a serial number (unique). Serial numbers do not necessarily follow themselves, because they are assigned at the beginning of the manufacturing process.

 

 

*** On the ULM / LSA models, the blades do not have a reference number, only a serial number on blade's foot. Be careful, sometimes this number can be slightly erased, because all feet are rectified after dimensional control on the machining centre 8-axis TRM-8. With the RFID chip, it is easy to find all technical data of the blade.

epropsTo know if a blade or a propeller can be repaired, you may send pictures to our commercial department. Please send files with a reasonable size.

Indicate the serial number of the broken blade (or the one of the good remaining blade)

Please note : if an incident or a shock require an important repair, this one must be realized by E-PROPS in its workshops, or by a specialist after discussions with the team E-PROPS. Be careful with the propellers repaired without agreement : do not forget that the propellers have a max rotation speed at tips more than 600 km/h. A repair has to be properly carried out.
