A wind turbine with reduced electromagnetic scattering includes a wind turbine support structure having a cylindrical shape, a wind turbine blade supported by the wind support structure, and a plurality of multi-layer absorbers to limit the electromagnetic scattering, the absorber including at least cobalt ferrite alloy nano-particles, cobalt ferrite alloy nano-flakes, and air. The wind turbine blade includes a blade root, a blade tip opposite the blade root, and a blade middle part extending between the blade root and the blade tip. The plurality of multi-layer absorbers further includes a planar absorber that covers the wind turbine support structure, and a curved absorber that covers the middle part.
摘要:
One aspect is a pump device comprising an impeller, and a pump housing which at least partly surrounds an interior region and has an inlet and an outlet, wherein the impeller is provided in the interior region of the pump housing. The pump housing comprises a composite of a first hollow body and a further hollow body which at least partly surrounds the first hollow body on the side facing away from the interior region. At least 60% of the surface area of the side of the first hollow body facing away from the interior space is connected to the further hollow body. The further surface of the first hollow body facing the interior region of the pump housing has a hardness of at least 330 HV.
