Advanced Aircraft Analysis New Version Releases

NEW RELEASE: AAA VERSION 3.3

Advanced Aircraft Analysis Version 3.3 contains many enhancements and revisions to version 3.2. Please refer to What's New in AAA 3.3 for a complete listing of modifications and bug fixes.

• Addition of Wind Tunnel module to correct aerodynamic data and stability and control data from wind tunnel scale to full scale.
• More GOTO buttons have been added to variables.
• Help is expanded.
• More interim variables are shown in the output.
• L/D from Weights has been moved from Class I Drag to Weight Sizing.
• Untrimmed Drag Trendline option has been added to the Recalculate Dialog window.
• Trim Diagram uses wing stall angles of attack.
• Wing Incidence is shown in the legend of the trim diagram.
• A Material Factor field has been implemented in Class II Structures Weights to account for composite construction for all structural components.
• V-n Diagrams show all the load values from the gust corner points as outputs.
• Both the V-n Diagram module and plotting of the V-n Diagram have been added to the Recalculate All window.
• When loading files from previous versions, AAA now performs a check for certain variables within the V-n Diagram module that are marked Flight Condition Independent and informs the user if AAA believes those certain variables should be switched from Flight Condition Independent to Flight Condition Dependent.
• Unnecessary output variables have been removed from the FAR 25 V-n Module.
• A wing structure factor has been added to allow the user to define how much wing structure is in the fuselage to take into account the weight of the structure inside the fuselage.
• A horizontal tail structure factor has been added to allow the user to define how much tail structure is in the fuselage to take into account the weight of the structure inside the fuselage.
• A vertical tail structure factor has been added to allow the user to define how much tail structure is in the fuselage to take into account the weight of the structure inside the fuselage.
• A V-tail structure factor has been added to allow the user to define how much tail structure is in the fuselage to take into account the weight of the structure inside the fuselage.
• A canard structure factor has been added to allow the user to define how much canard structure is in the fuselage to take into account the weight of the structure inside the fuselage.
• AAA now recognizes independent sets of geometry for elevons and ailerons on flying wing configurations.
• The input values for the Thrust/Power versus speed plot are now shown as points on the curves.
• The pylon drag coefficients and friction coefficients are shown to the user.
• The Fwd-Aft C.G. Plot now displays the location of the empty weight C.G. and the most forward and most aft xcg locations are shown in the legend.
• FAR23 Velocity-load (V-n) Diagram has been revamped to reflect current FAR23 methods, as opposed to the simplified methods of Roskam Airplane Design Part V.
• Total C.G. now plots a sideview of the airplane with all variable c.g. components.

What's New in AAA 3.3

End of Support for AAA 3.2 & earlier: With the release of Advanced Aircraft Analysis (AAA) Version 3.3, DARcorporation will no longer support AAA Versions 3.2 and earlier. AAA is a perpetual license so this will not affect the performance of AAA, however, we will no longer support software installation or replace damaged WIBU Keys. If you have AAA Version 2.5 and earlier: We will no longer support unlock key requests. It is recommended to copy the file c:\program files\aaa2.x\License\aaa.lf (onto a CD or other computer).
