AeroPack is a collection of unique drawing tools created specifically for airplane design and drafting that can also read geometric information from the Advanced Aircraft Analysis (AAA) analysis modules. AeroPack is an add-on enhancement to Shark FX, which is a separate full featured 2D and 3D digital design solutions that provide versatile modeling practices and precision drafting capabilities all within one seamlessly integrated package.
Airfoils can be constructed from files (spline through digitized points) or from NACA/NASA equations.
Using the Obscuration tool, the field of view of a pilot, sensor or antenna can be calculated and plotted. This plot will show any obstructions in the field of view from a selected point.
The wing planform tool creates half of a wing outline, which is specific plane, consisting of leading and trailing edges along with root and tip chords. Based on provided information of aspect ratio, surface area, taper ratio and sweep of the quarter chord line, a planform will be created.
Area/CG Curve calculates and displays as a graph the cross sectional area of a component or complete configuration as a function of the distance along a specified axis. This tool is useful for area-ruling transonic or supersonic cruise airplanes.
Sum Curves allows the user to add two or more curves together. It can be used to sum Area/CG curves from different components.
Mean Geometric Chord
Mean Geometric Chord calculates the length and location of the Mean Geometric Chord for straight-tapered and cranked planforms.
Perimeter curve creates a plot of perimeter length as a function of body stations. When used in conjunction with the Curve Integration tool, the Perimeter Curve tool can be used to find the wetted area of components.
A Polyconic Surface is a surface constructed along a path of smoothly changing conic sections. Adjacent surfaces can be easily made exactly tangent to each other so there will be no bumps or dips in your finished airplane. This result is very important in composite airplanes with smooth surfaces that reveal the slightest errors in curve geometry, but nearly impossible to achieve with conventional or freeform curve drawing methods.
Space Spline creates a combined projection between two existing curves. Useful when creating control curves for polyconic surfaces.
Curve Integration will numerically integrate a curve to find the area underneath it. Used in conjunction with the Perimeter Curve and Area/CG Curve tools to find wetted areas and volumes, respectively.
Import Airplane allows the user to create files in AeroPack based on data from .geo files created by Advanced Aircraft Analysis.
The Replace Curve tool quickly updates geometry by replacing one curve with another in the feature tree of all objects in the model. This means that all geometry created from the original curve will update to the new curve. Useful when changing airfoils of lifting surfaces.
Export Curve exports the coordinates of a curve to a .spl file. This file can be imported back into Shark FX for use in future models.
Plot Curve produces graphs of inflection points, curvature and first derivatives.
