Modern commercial aircraft are exploring new technologies with the aim of achieving significant improvements in fuel consumption, aircraft weight, reliability, total life-cycle cost, and environmental impact. This demand is driving the aerospace industry towards a more-electric-aircraft philosophy, minimizing the use of hydraulic and pneumatic power in favor of the use of electric power. The electric power system will become increasingly crucial, as will its components. Furthermore, the use of drones is much more economical and less invasive than helicopters for civil protection and aerial photography, further increasing the demand for electric motors. New approaches and technologies are being explored to increase the reliability and performance of this subsystem, and one of them is the optical fiber, which was already tested in high-performance aircraft.
