Advanced Aircraft Analysis 3.1 released

DARcorporation is proud to announce the release of the latest version of our premier aircraft design software, Advanced Aircraft Analysis (AAA) version 3.1. AAA is the industry standard preliminary and Class II design software, with users in major aeronautical universities, aircraft manufacturers, and military organizations in over 40 countries around the world.

Advanced Aircraft Analysis (AAA) 3.1 features a number of improvements and additions that will even further cement its position as the foremost aircraft design software available today:

• Weight Sizing Module has a useful load feature where one can vary the payload and calculate and plot the corresponding cruise ranges for the same empty weight and take-off weight.

• Class I Drag has a new option "L/D from Weights". This calculates the climb, cruise, turn and loiter lift-to-drag ratios, based on corresponding segment weights. It iterates between Weight Sizing and Class I Drag (as the wetted area is calculated from take-off weight) to obtain a converged solution for the take-off weight.

• Center of Gravity under Class II Weight has a new option "Useful Load" where the passengers can be divided into different classes (class 1, 2, 3 or 4 depending on whether it is business, economy, coach etc...). The corresponding group weights are calculated and used in the center of gravity (C.G.) calculations.

• Center of Gravity under Class II Weight has an option Forward-Aft C.G. to plot the variation of the static margin and the center of gravity travel with wing location.

• Fuselage Geometry has an enhanced feature where the cross-sectional areas and the fuselage camber line are plotted as a function of the fuselage stations. The data from this plot is used for the calculation of the aerodynamic center and the zero-lift pitching moment of the fuselage.

• AeroPack under Geometry can export each airplane geometry component into Concepts Unlimited as a CAD file.

• The fuselage, tailboom, nacelle and store under AeroPack in Geometry can be defined in two coordinate systems: a local coordinate system and airplane coordinate system. This allows the user to change the orientation of the component, without having to re-enter all coordinates.

• The Fuel Weight Center of Gravity is included in the Recalculate option.
