Abstract (en)
The ventilator has ventilator blades (2) fastened to a shaft or a hub part, where the ventilator is used in a turbo machine operating at speed of 3600 revolutions per minute. The blades are arranged in the form of a bayonet connection with a locking device e.g. fixing screw, to the shaft or the hub part, where the ventilator blades are angle-adjustable. The ventilator blades form a material compound representing a material meshwork or a chemical compound, where the material meshwork contains carbon fibers and Kevlar fibers.
