VAC successfully participated in the Electric & Hybrid Aerospace Technology Symposium. The trend towards electrification and hybridization of drives continues unbroken. The cobalt-iron (CoFe) high-performance materials of the VACUUMSCHMELZE (VAC) are an unique opportunity to combine the necessary technical requirements with size and weight reductions.
The CoFe material VACODUR®49 fully exploits its advantages in turboelectric hybrid systems: better flux control can typically increase the power density, one of the most important properties of synchronous machines, by 30 %. This allows the torque and maximum power (constant size/weight) to be increased or the required size and weight (constant torque/power) to be minimized.
VACODUR is characterized by a high magnetic saturation of up to 2.3 T in combination with low coercivity. Adapted annealing temperatures meet the demanding strength requirements for high speeds. The wide range of alloys and laminations available is widely used in new projects for hybrid or all-electric aircraft, both in the generator and in the propulsion motor. This enables designers to achieve the optimum balance between torque and weight.
“All major aircraft engine manufacturers are involved in the hybridization of short- and medium-haul aircraft. The aim is not only to reduce fuel consumption, but also to reduce the cost of noise protection measures and bypass flight bans by significantly reducing noise during take-off and landing,” says Dr. Robert Brand, Application Specialist at VAC.
