TL;DR: A bibliographical review of technologies for landing gear noise reduction, taking the Technology Readiness Level (TRL) into consideration, is presented.

TL;DR: This bibliographic survey systematically review the progresses and trends of the bio- inspired aerodynamic noise control, including the macroscopic and microscopic morphological characteristics of the owl wing feathers, the noise measurements on both flying birds in the field and prepared wings in the wind tunnel, as well as theoretical, numerical and experimental studies that explored the feasibility, parameter influence, aerodynamic effects and underlying mechanisms of the four main bio-inspired noise reduction techniques.

TL;DR: In this article, a dual-jet planar air curtains are demonstrated to successfully remove aerodynamic noise radiated from tandem rods in a cross-flow, achieving the same shielding height with a significantly lower overall system noise.

TL;DR: An orthogonal augment radial basis function (OA-RBF) method, for estimating a general class of Sobol’ indices and results obtained indicate that the approach proposed here can be utilized for GSA of industrial-scale engineering problems.

TL;DR: A general and efficient method for constructing LHDs possessing favorable characteristics of orthogonality and better computational efficiency is first proposed and a sequentially enlarging strategy is derived based on the initial design.
