THE POWER MAST

The revolutionary Power Mast with 2 sets of co-axial counter-rotating propellers (4 eFANS)

F-HELIX IS BASED ON AN EXISTING PLATFORM :
THE SILVERCRAFT SH4 CERTIFIED by F.A.A (N° H2EU) in U.S.A. (N° IM 54) in FRANCE and R.A.I (N° A 145) in ITALY

Mounting the electric propellers directly on the main rotor leads to no torque exchange betwen main rotor and fuselage.

The Powermast makes useless:

  • Fuel Engine
  • Main rotor
  • Tail rotor
  • Tank Fuel
  • Free wheel
  • Tail beam
  • Oil pump
  • Oil tank
  • Lubrication system
  • Engine shroud

The Result:

  • Green Flight
  • Low Cost
  • Low Noise
  • Easy to pilot (Autopilot ready)

This allows us to save around 1000 lb that are allocated to the battery pack or to the payload.

This means more load capacity and longer flight duration in the near future

THE 2 YAW eFANS

The two small electric ducted fans are used to provide control and directional stability around the yaw axis.

No torque exchanged between
the main rotor and fuselage.

Blue Edge-Like Blades

50% less noise

Compared with a conventional blade, the Blue Edge has a tip with both forward and rearward sweep. This gives the blade more time to interact with the vortex 'shed' by the rotor, reducing the characteristic impulsive (slap-slap) blade-vortex interaction noise generated by a helicopter

Blue Edge is a trade mark of Eurocopter.
