3. The aerodynamics team have come back to you with a new design which has been modified for better performance, since the Mark I does not produce enough lift. Figure 2 shows the layout of the new rotor blade and corresponding aerofoils used. SC1095 Aerofoil SC1094R8 Aerofoil SC1095 Aerofoil r_start r_end Figure 2: Aerofoil Sections of Mark II Rotor Blade Table 2 contains the chord length and aerofoil type at the key stages along the blade.

Plot this distribution using 101 points. Explain how you created this distribution. (Hint: you should use a linear interpolation to get the area between the data points given above) (5%)
