Definitions
- Newer pump concepts for fuel delivery systems for jet engines of aircraft provide an electric drive, which drives a pump module via a drive shaft. Both failure of the engine assembly and failure of the sealing elements between the engine assembly and the centrifugal pump can result in failure of the fuel delivery to the aircraft engine.
- the rotors may be designed in the manner of a type, annular disk rotors, which may have one-sided grooved short-circuit cages.
- An advantageous embodiment of the motor modules can be achieved by a type of axial flux machine, which is designed as an asynchronous motor or as a reluctance motor with one-sided slotted star rotors.
