Heliciel uses two main types of propellers:

1: Propeller turbine for energy recovery, designed to capture the kinetic energy of a fluid, Exemples:

Wind turbines and windmills are equipped with propellers capturing energy from the wind.

The Kaplan turbine propellers type capture the kinetics energy of a stream of water .

the tidal turbines are submerged propellers that capture the energy of ocean curren

2:Propellers intended to supply energy to the fluid . Exemples:

Fans and ventilators provides energy to the air by increasing its speed or pressure

the propellers of the aircraft or ship propellers, accelerate the fluid in which they move, the change in the momentum of the air or water generates the propulsive force by reaction on the propeller.

The axial flow pumps or fan pump, supply energy by increasing the pressure or the flow velocity
