ULTRA-LIGHT CARBON PROPELLERS for DRONES & UAV
E-PROPS : Fixed Pitch Propellers for engines 7-50 kW dia 45 to 63 inch
DESCRIPTION
✗ Full carbon propellers, fixed pitch
✗ Ultra-light : 30 to 60 % less than other composite propellers on the market
✗ For engines from 7 to 50 kW
✗ Diameters : from 45 to 63 inch, each 2 inch (115 cm to 160 cm, each 5 cm)
✗ Each model available in : 2-, 3-, 4- and 6- blades
✗ Models each 0,5° pitch
✗ Tractor and pusher configurations
✗ Available in both rotation senses : CW and CCW
✗ Click here to see : Traction & Torque curves - Pitches of this range
1- Tightening torque
2- Dismounting
3- Max RPM - Sense of Rotation
4- Max Power
5- Maintenance
6- Data Sheet / Manual
The screws tightening must be done with a torque wrench; torque value depending on the screws :
Screws 6 mm = 8 N.m
Screws 8 mm = 16 N.m
Fixed-pitch propellers can be dismantled, into 2 blades for 2-blade models, or into 3 blades for 3-blade models, etc...
It's practical for transport and storage, and in the event of impact on a blade, it can be replaced without changing the whole propeller.
The maximum rotational speed (at the propeller = maximum engine speed / reduction ratio) depends on the propeller diameter, the number of blades and the blade pitch adopted.
It is indicated on the Traction / Torque curves of this range
The rotation sense of a propeller is always defined seen in the wind made by the propeller :
- clockwise sense (CW)
- counterclockwise sense (CCW)
The maximum power the propeller can absorb depends on each propeller model.
It is indicated on the Traction / Torque curves of this range
Warning: on electric motors, the maximum rpm of the motor very often depends on the battery voltage.
The maximum power reduces the battery voltage and therefore the maximum rpm.
This data must be taken into account to define the desired propeller model on the curves.
Maintenance is simple :
- Before each flight: visual inspection of the propeller (particularly check the leading edge) and check the screws tightening.
- Every 50 hours of flight or every 3 months : check of the screws tightening.
Cleaning of a carbon propeller is made with a sponge, with some water with soap, or with a product for windows cleaning.
Propellers are not accessories. Before assembly and use, read and follow Manuals & Instructions.
