In this paper, a multidisciplinary optimization design method and its verification of low-noise aircraft propellers considering aerodynamics, noise, structural strength were carried out to further reduce the aerodynamic noise propellers. The Vortex Lattice Method-based Lift Surface Method Frequency-Domain-based Hanson deployed evaluate performance far-field propeller with validation by benchmar...

The device operates at temperatures <300 mK and comprises a hafnium microbridge superconducting aluminum tunnel junction both integrated into common coplanar waveguide. matches with planar antenna as an optical blackbody frequencies 600-700 GHz. terminal is the output in 1-2 GHz frequency range. temperature can be set range of 0.4-9 K calibrated using shot noise junction. Temperature mod...
