----------------------------------------------------------------------------------------- VLAERO+ Revision Log ----------------------------------------------------------------------------------------- Last Updated: September 1, 2008 (A. McComas) ----------------------------------------------------------------------------------------- ---- Version 2.1.002 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - BUG FIX: Fixed bug which resulted in non-sensible results with complex control surface definitions ----------------------------------------------------------------------------------------- ---- Version 2.1.001 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - FEATURE: Introduced Carlson's leading edge suction analogy. - FEATURE: Added airfoil camberline solver to determine location of mean camberline, thickness and leading edge radius. This tool compliments the input requirements of Carlson's leanding edge suction analogy. - USABILITY: Drag model updated to the following: Pressure Drag is the sum of the panel normal force rotated to the streamwise direction and the streamwise component of the leading edge suction, as defined parallel to the lifting surface. The drag model will return the same result as that in prior version when the Trefftz model is selected with 100% attainable leading edge suction (default). ----------------------------------------------------------------------------------------- ---- Version 2.0.038 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- IMPORTANT: Version 2.0.038 will be the last sub-minor revision for VLAERO+ 2.0. The next release of VLAERO+ will be version 2.1.0 and will incorporate an improved leading edge suction model as well as some other enhancements. Only customers with active maintenenace contracts will be eligable to upgrade. Please contact AMI to renew your maintenance contract or to request a quote for purchase. - BUG FIX: Calibration tables were not saved when specified in the component editor when that was the only change made. ----------------------------------------------------------------------------------------- ---- Version 2.0.037 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - BUG FIX: Fixed a bug in the leading edge suction routine for supersonic calculations. The leading edge suction was not being scaled properly from Mach 1 to the Mach number for a Mach cone angle equal to the leading edge sweep angle. This bug occured for models with multiple components. ----------------------------------------------------------------------------------------- ---- Version 2.0.036 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - BUG FIX: Removed bug introduced in v2.0.035 which caused error when enqueuing and running multiple jobs. - BUG FIX: Fixed problem where some components would not be mirrored when using the 'Create Full Model from Half Model' tool. - USABILITY: Added an additional digit of precision to the standard job editor fields. - FEATURE: Added a join components at edges feature to the component tools. - FEATURE: Added the grouped component tools to the standard job tools to allow group operations to be performed on all active components in a job. This allows vortex impingement check to be performed on a single job. ----------------------------------------------------------------------------------------- ---- Version 2.0.035 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - FEATURE: Added matrix execution feature to allow execution of multiple project files as a batch in one instance of VLAERO+. - FEATURE: Added ability to obtain trim and fixed control surface solution in a single job. Derivatives are obtained about the fixed deflection for derivative jobs. Fixed deflections appear in the CAMBER solution for derivative jobs. - USABILITY: Component icons in the model explorer now indicate the component side. L = Left of xz-plane, R = Right of xz-plane, C = exclusively on xz-plane L/R spans both sides of xz-plane - USABILITY: Job icons in the job explorer now idicate the job mode: S&C = Stability and Control Derivative Job, TOT = Totals Job, TRM = Trim Job - BUG FIX: Control surfaces with empty flap references were being ignored in the solution. Fixed. - BUG FIX: Control derivatives were in error for jobs with non-zero linearization point. Fixed. ----------------------------------------------------------------------------------------- ---- Version 2.0.034 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - BUG FIX: Delay when queuing large models significantly reduced. - BUG FIX: Conflict resolution indicated component has zero span for components symmetrically spanning the centerline preventing execution, fixed. - USABILITY: Added words to planform editor to indicate why it is deactive for RHS trapezoids. - USABILITY: Online help much faster to load and switch topics. - USABILITY: Control surface editor will remove stale component linkages on Ok. - FEATURE: When viewing a solution, the normal vectors are now rotated by the solution panel slope. This allows representation of flaps+alpha+twist+camber+rotary angles. ----------------------------------------------------------------------------------------- ---- Version 2.0.033 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - USABILITY: Added "Welcome to VLAERO+" wizard to assist with license key installation and/or specification of the license server location. - USABILITY: Added licence expiration warning on startup. ----------------------------------------------------------------------------------------- ---- Version 2.0.032 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - FEATURE: Added host-name output on initial execution. ----------------------------------------------------------------------------------------- ---- Version 2.0.031 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - BUG FIX: Changing panel set component assignment would not save in the control editor if that was the only change. - BUG FIX: Fixes a bug introduced in v2.0.029 which prevented assignment of calibration tables in the component editor. ----------------------------------------------------------------------------------------- ---- Version 2.0.030 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - BUG FIX: Fixes a bug introduced in v2.0.029 which prevented the renaming of a component. - BUG FIX: Fixes a bug introduced in v2.0.029 which prevented assignment of grouped components. - USABILITY: Added a 'Select All' and 'Select None' buttons to grouped component editor. ----------------------------------------------------------------------------------------- ---- Version 2.0.029 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- - BUG FIX: When executing a solution with multiple derivative control surfaces, the following error message would be displayed: *** ERROR IN INPUT *** *** UNEXPECTED WORD - *** - BUG FIX: Removed limitation preventing execution on x64 versions of Windows. - USABILITY: Eliminated a blank license manager error. - USABILITY: Removed screen flicker on some forms. - USABILITY: Moved the beam and mass properties to sub-dialogs to reduce component editor load time. ----------------------------------------------------------------------------------------- ---- Version 2.0.025 -------------------------------------------------------------------- ----------------------------------------------------------------------------------------- This constitutes the first general release of VLAERO+2.0. The graphical user interface (GUI) has been re-written from scratch to support all of the solver technology available in the acclaimed VLAERO8.0 vortex lattice solver. The GUI was developed using the Microsoft .NET 2.0 framework and basic functionality has been verified under the following operating systems: - Windows XP Professional - Windows Vista Ultimate - Windows 2003 Server x64 Comments, bug reports and feature requests can be sent to: Andrew McComas VLAERO+ Developer mccomas@amiwest.com
