Question: How do you ensure that the aerodynamics of the product being designed are correct and symmetrical?

Hi Archie,
For the aerodynamics there are specific packages that simulate how the fluid particles move around a body. The maths behind them is very complex and the code usually take long to run. For symmetry, there are ways to ensure that your model is symmetric. In reality there will always be some differences due to the assembly for example or the manufacturing process itself. But the designs normally take these sources of difference into account. For each component you define some ‘tolerances’ which define a window of variability within which your design and performance is acceptable.
