Weight

 

 

 

Some models weigth less than 450 gr !

About 30 to 60% less than competitor props

The E-PROPS are the lightest propellers on the market

 

Blades

 

 

 

 

 

 

100% carbon + epoxy resin

Optimum use of carbon fibers braid to obtain light and strong blades

Foam core with D-Box

RTM manufacturing process

=> see manufacturing

Carbon braid, with continue fibers between upper and lower surfaces of the blade.

The HCF (Helical Continuous Fibers) process, 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.

 

Blade's foot

 

 

Two sectionnable parts, very simple to assembly

Thickness of the blade's foot : 28 mm for standard / 38 mm for Scimitar range

 

Tips

 

 

 

E-PROPS has made extensive research on the blades tips, with many tests on different configurations : rounded, cut with angles, with upper or lower winglets... The best performances and the lower noise are reached with a straight cut tip. All other configurations are for marketing.

 

Leading edge protection

 

 

 

Strong leading edge protection

Internal shielding of the blades : injection at the leading edge of a special resin with Nanostrength® (ARKEMA product : high kinetic energy absorption capacity)

 

Moment of Inertia

 

 

 

About 500 kg.cm² [for a 125 cm diameter model]

Strict respect of the limitations of the engines manufacturers

=> see moment of inertia

 

Balancing

Tracability / blade's remplacement

 

 

 

 

 

 

 

 

 

 

 

Model's ref on each blade

A RFID chip is inserted in each blade, with all technical data inside.

Unique serial number on each blade

Strict quality control; quick replacement of one blade possible

=> see manufacturing

To know if a blade can be repaired or not, please send pictures of the damages and indicate the serial number (4 or 4 numbers).

Please note : the serial numbers do not necessarily follow each other. Those serial numbers are assigned at the beginning of the manufacturing process (for the best tracability), and at the end the propellers are balanced with different blades series. Il is normal to have different serial numbers on the blades of the same propeller.

 

Mechanical Strength / Tests

 

 

 

 

Centrifugal load tests : HEP_PLUG_centrifugal_load.pdf

Carbon propeller can hold 4 times the maximal load during 1 hour without any damages (AESA standards ask for 2 times)

=> the E-PROPS are extremely strong propellers

 

Tracking / Dynamic Gap

 

 

 

 

 

 

The maximum static tracking is 25 mm (tracking is not important if you haven't vibrations).

Dynamic gap : up to 2 cm (the blade can move towards the engine at max power)

This gap is depending on the engine assembly, on the cage and on the silent-blocks.

It is recommanded to part the propeller from the cage of minimum 4 cm.

 

Holes

 

 

 

 

 

 

 

The holes on the PLUG'n'FLY are made to adapted to each engine - reducer.

On some models, drilling parterns are using only 4 holes on the 6 holes. It is normal and those configurations have been calculated and tested.

6-blades propellers are assembled on 130 hp engines by 6 screws M8; 4 screws M8 are enough to assemble a propeller on a 35 hp engine.

Never put a rubber spacer between the reducer and the propeller; the screws would break.

 

Torque

 

 

Screws 6 mm = 10 N.m

Screws 8 mm = 20 N.m

 

Max RPM

 

3.000 RPM measured at propeller = engine max RPM / reducer ratio

 

Max power

 

 

about 35 hp on engine with reducer

Never user a PLUG'n'FLY propeller on a thermic direct drive engine

 

Maintenance

 

 

 

 

 

Maintenance before each flight: visual inspection of the propeller and check of the screws

Periodic maintenance: check of the tightening every 25 hours of flight or every 3 months

Cleaning of a carbon propeller is made with a sponge, with some water with soap, or with a product for windows cleaning.

Small impacts / Repairs

 

 

 

Small impacts can be easily repaired (epoxy or araldite resin, small sanding)

If an incident or a shock require an important repair, this one must be realized by HELICES E-PROPS or an agreed repairing center.

Advantages of a PLUG'n'FLY propeller

 

 

VERY LIGHT (the lightest on the market)

- less than 500 gr for a 2-blades diameter 125 cm

- more resistant propeller => faster acceleration and deceleration of the engine (the propeller is more reactive, it stops much more fast, that is fewer risks of break in case of shock in the propeller), less stored kinetic energy, thus fewer damages in case of impact.
- comfort increased for the pilot = > less mass propeller on the back, fewer gyroscopic efforts, less couple
- better functioning of the engine = > fewer constraints on the reducer, fewer vibrations due to the functioning propeller

 

 

EXTREMELY STRONG

- 100% carbon + epoxy resin : optimum use of carbon fibers braid to obtain light and strong blade. Foam core with D-Box. RTM manufacturing process.

- Helical Continuous Fibers : HCF process, specifically designed by E-PROPS, ensures an exceptional strength of the 100% carbone + epoxy resin blade, from leading edge to trailing edge, from blade's foot to tip.

- Leading edge protection : injection at the leading edge of a special resin with Nanostrength® (ARKEMA product : high kinetic energy absorption capacity)

 

 

SPECIAL PATENTED PROFILES AND GEOMETRIES

- Specific E-PROPS design with high CL profiles and scimitar form (curved): more thrust, fuel economy and noise reduction

 

 

DISASSEMBLED

- interesting for storage and transport

- very easy to assemble and disassemble

- simple replacement of one blade

WARNING :

On some models drilling parterns are using only 4 holes on the 6 holes. It is normal and those configurations have been calculated and tested.

We have sold hundreds of those models and they are flying worldwide since years.
