What is it about?
A strut-braced Ultra-High Aspect Ratio Wing (UHARW) design can improve aerodynamic efficiency and reduce fuel consumption for future aircraft. However, adding a bracing strut increases noise, particularly dipole noise and trailing-edge noise. Simulations show a noise increase of 3.5 dB near the bracing strut and a 0.8 PNLdB rise in overall wing noise, though the effects of other noise sources were not considered.
