“…They all achieved good prediction results but do not research on the physical quantities which affect aerodynamic noise. Antonio et al [4], Marinus and Roger [5], and Campos and Lau [6] have complimented the multiobjective optimization design of propeller aerodynamic noise. But they did not finish the application of blade noise reduction optimization and performance analysis of the blade after noise reduction.…”

Aiming at the problem of excessive propeller noise in a new type of electric aircraft, in order to ensure the propeller aerodynamic characteristics simultaneously, a noise reduction method for improving the shape of the blade along the spanwise is proposed. The FW-H model, the unsteady slip mesh, and the large eddy simulation method are investigated to obtain the aerodynamic noise spectrum. Initially, through propeller aerodynamic noise numerical simulation, we obtain the sound pressure and aircraft aerodynamic noise in frequency domain. Subsequently, the effectiveness of our method is verified by comparing the experimental data and numerical results. Based on the established calculation model and method, under three different rotation speeds, the distribution law of the sound pressure level of the propeller with different shapes along the spanwise is analyzed, and the influence of the blade shape on the aerodynamic noise of the propeller is obtained. The research shows that the aerodynamic noise of the new blade compared to the original blade is significantly reduced at the same rotation speed higher than 1000 rpm, indicating that the blade load noise plays a dominant role in the aerodynamic noise and can be effectively reduced by changing the blade shape along the spanwise, thus reducing the aerodynamic noise of the blade.

Nowadays, the solution of multiobjective optimization problems in aeronautical and aerospace engineering has become a standard practice. These two fields offer highly complex search spaces with different sources of difficulty, which are amenable to the use of alternative search techniques such as metaheuristics, since they require little domain information to operate. From the several metaheuristics available, multiobjective evolutionary algorithms (MOEAs) have become particularly popular, mainly because of their availability, ease of use, and flexibility. This paper presents a taxonomy and a comprehensive review of applications of MOEAs in aeronautical and aerospace design problems. The review includes both the characteristics of the specific MOEA adopted in each case, as well as the features of the problems being solved with them. The advantages and disadvantages of each type of approach are also briefly addressed. We also provide a set of general guidelines for using and designing MOEAs for aeronautical and aerospace engineering problems. In the final part of the paper, we provide some potential paths for future research, which we consider promising within this area.

Additively-manufactured wings can be aeroelastically tailored, which offers potential for increased air vehicle efficiency via lighter structures. This paper develops a methodology to design aeroelastically-tailored wings using additively-manufactured lattice structures. Adaptive meshing techniques are used to design the topology of the lattice to align with the load direction and the lattice is optimized to minimize the structural weight and to improve the flutter margin. To alleviate the computational effort of aeroelastically tailoring a structure, a low-order model for the dynamics of the lattice structure is developed. This structural low-order model is coupled to a previously-developed physics-based transonic flutter model to compute the aeroelastic behavior of wings with internal lattice structures. The structural low-order model is validated by comparing against the full-order structural dynamics model. Finally, the design methodology is applied to the design of an internal structure of an aircraft wing to increase that wing's flutter speed.
