Submodules¶
ntrfc.turbo.airfoil_generators.naca_airfoil_creator module¶
Python 2 and 3 code to generate 4 and 5 digit NACA profiles
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word “NACA”. The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties.

- ntrfc.turbo.airfoil_generators.naca_airfoil_creator.interpolate(xa, ya, queryPoints)¶
A cubic spline interpolation on a given set of points (x,y) Recalculates everything on every call which is far from efficient but does the job for now should eventually be replaced by an external helper class
- ntrfc.turbo.airfoil_generators.naca_airfoil_creator.linspace(start, stop, np)¶
Emulate Matlab linspace

- ntrfc.turbo.airfoil_generators.naca_airfoil_creator.naca5(number, n, finite_te=False, half_cosine_spacing=False)¶
Returns 2*n+1 points in [0 1] for the given 5 digit NACA number string
