2018.07.05. The dream of electric flying

Hanau - Demands for lower kerosene consumption, lower pollutant emissions and reduced noise pollution are increasing in aviation and are driving the development of full-electric and hybrid-powered aircraft. The related demand for light yet powerful engines brings the high-performance materials of VACUUMSCHMELZE (VAC) into play.

Not only numerous start- ups, but also renowned companies are pushing development forward. VAC will be happy to advise on this on the occasion of CWIEME 2018 in Berlin. While the Swiss start-up Evolaris has already launched an all-electric aircraft using VAC materials, industry leaders are working on hybrid solutions for commercially used long-haul aircraft.

With these, a kerosene driven turbine, which operates at any time at constant speed in the optimum power range, feeds a generator. This in turn drives the all-electric main drive. This is estimated to result in kerosene savings of more than ten percent. For both technical concepts, the highest possible induction with low losses is decisive. Stators made of the cobalt-iron alloy VACOFLUX® 48 are therefore the first choice.

They allow a 50 % higher induction compared to systems with electrical steel. The patented VACSTACK® technology allows the tightest tolerances to be kept and the low sheet thickness of only 50 µm allows 98 % packing density and the lowest eddy current losses to be produced. Rotor systems with rare-earth permanent magnets made of VACOMAX® 262 HRP make it possible to maximize torque and acceleration in the smallest and most reliable size even at high application temperatures of up to 250 °C.

"At this year's CWIEME Berlin we will present the latest developments and products on the main topics of electric drives, especially for aviation and automotive applications. We are delighted to have the opportunity to discuss individual solutions with interested parties on site," says Norman Lemm, Head of Marketing at VAC.
