Care is needed with this, so that the geometry of the aerofoil is preserved.
They can select an aerofoil shape and choose values for the chord, the blade thickness, the camber etc, with confidence that these values will be realised quite closely in their model blades.
30 and table 14 where it is observed that the aerofoils for the root and break point 1 stations contain a less max-thickness when compared to initial design aerofoils while the aerofoil for break point 2 and tip station is thicker than initial aerofoil.
The aerofoil sections are compared in figure 38 and table 17 where it can be seen that the aerofoils for the root and break point 1 have a less max-thickness compared to initial design, however for the break point 2 and tip, the thickness of aerofoil is higher and the positive cambers are observed.
The improvement of the aerodynamic performance of UAV/UCAVs can be achieved by optimising the aerofoil shapes for the aerofoil sections (2, 5, 8, 17, 22) and wing planform (3), (12, 13, 25).
In this paper, a methodology was developed for the aerodynamic optimisation of the wing aerofoil sections and planform using a MOEA.
The method couples the Hierarchical Asynchronous Parallel Evolutionary Algorithms (HAPEA) with several aerodynamic analysis tools for the design and optimisation of UCAV aerofoil sections and planform shapes.
The control points that define the aerofoil sections at three spanwise stations represent the design variables.
Concluding this case; the capabilities of this approach to find optimal shapes for inverse aerofoil sections shape optimisation problems is demonstrated.
Algorithm 2 illustrates the process for the wing aerofoil sections and planform shape design.
In most of the test cases considered in this paper, the aerofoil geometry is represented using Bezier curves with a combination of a mean line and thickness distribution.
