An electricity generation system

An electricity generation system (1) comprising:

• a body (2) situated at air vehicles;
• at least one rotor (3) extending longitudinally out of the body (2) and rotating around an axis along which it extends;
• at least one blade (4) connected to the rotor (3), which, upon triggering of the rotor (3), rotates around the axis along which the rotor (3) extends, thus creating an aerodynamic lifting force required for the body (2) to take-off;
• a blade tip (5) which is located on the blade (4), at the end of a direction along which the blade (4) extends;
• and
• at least one plate (6) made of a piezoelectric material, which is located on the blade (4) and enables energy conversion, wherein the plate (6) is located on the blade (4) so that it is monolithic with an aerodynamic surface of the blade (4), allows the mechanical energy of elastic deformation on the blade (4) oscillating due to aeroelastic forces to be converted into electrical energy, and enables conversion of the tension and/or strain occurring on the blade (4) due to the elastic deformation of the blade (4) into electrical energy due to its piezoelectric structure;
• a first region (I) located on the blade (4) closer to the blade tip (5);
• a second region (II) located on the blade (4) between the rotor (3) and the first region (I), wherein the distance between the first region (I) and the second region (II) is at least as much as the distance between the second region (II) and the rotor (3), wherein a plurality of plates (6) are located on the blade (4) so as to be only in the first region (I) and only in the second region (II).
