Bayesian optimisation for low-noise aerofoil design with aerodynamic constraints

Mijn Mutation Operator for Aerofoil Design Optimisation

A new mutation operator, called Mijn, capable of operating on a set of adjacent bits in one single step, is introduced. Its features are examined and compared against those of the classical bit{{ip mutation. A simple Evolutionary Algorithm, M{EA, is described which is based only on selection and Mijn. This algorithm is used for the solution of an industrial problem, the Inverse Aerofoil Design ...

The Aerodynamic Noise of a Slot in an Aerofoil

SUMMARY This Report describes a theoretical investigation of the noise generated when turbulence interacts with a slot between a wing and flap. The slot is modelled by the region between two overlapping, semi-infinite rigid planes representing the wing and flap, and sound is produced when turbulence convects above, below or through the slot. The analysis determines the dependence of the radiate...

A morphing Aerofoil with Highly Controllable Aerodynamic Performance

In this paper, a morphing carbon fibre composite aerofoil concept with an active trailing edge is proposed. This aerofoil features of camber morphing with multiple degrees of freedom. The shape morphing is enabled by an innovative structure driven by an electrical actuation system that uses linear ultrasonic motors (LUSM) with compliant runners, enabling a full control of multiple degrees of fr...

Aerodynamic Design Optimisation for Complex Geometries Using Unstructured Grids

Optimisation of Aerodynamic and Coupled Aerodynamic-structural Design Using Parallel Genetic Algorithms

This paper describes a parallel genetic algorithm (GA) which is linked to aerodynamic and structural analysis for multidisciplinary optimisation of wings. The method has been applied to 2D aerodynamic section design, to the aerodynamic optimisation of wings and to combined aerodynamic and structural optimisation. The parallel genetic algorithm commences with the subdivision of the entire popula...
