Wing design with three-dimensional transonic inverse method.

Transonic Wing Design by Inverse Optimization Using Moga

An inverse optimization method coupled with a multiobjective Genetic Algorithm has been applied to design a transonic wing for mid-size regional aircraft. Optimization of target pressure distributions was formulated to give minimum induced drag as well as minimum profile drag. The straight isobar pattern of pressure contours was specified on the upper surface of the wing. To design a realistic ...

Design of Aspirated Compressor Blades Using Three-Dimensional Inverse Method

A three-dimensional viscous inverse method is extended to allow blading design with full interaction between the prescribed pressure-loading distribution and a specified transpiration scheme. Transpiration on blade surfaces and endwalls is implemented as inflow/outflow boundary conditions, and the basic modifications to the method are outlined. This paper focuses on a discussion concerning an a...

Optimum Transonic Wing Design Using Control Theory

1. Introduction While aerodynamic prediction methods based CFD are now well established , and quite accurate and robust, the ultimate need in the design process is to find the optimum shape which maximizes the aerodynamic performance. One way to approach this objective is to view it as a control problem, in which the wing is treated as a device which controls the flow to produce lift with minim...
