Profile Version 2.2 (Jan 1998) Copyright John Garnham 1995, and Francisco Arzu 1997-1998. Profile is a Windows 95 program intended to plot airfoils and templates. This is free software and is freely distributable under certain conditions; it comes with NO WARRANTY. See the GNU GPL included (GNU-GPL.txt) for details. Full Source code is also available for those who wants to play with it or add new futures. I want to keep responsible for incorporating all the changes into the official release, of course, I will give you credit of the changes!!. If some one wants to collaborate with a nicer manual let me know!! Frankie Arzu HISTORY --------------- Version 2.2 (1998) by Frankie Arzu. First, I want to thanks Stone, Jon for fixing some printing problems, he rewrote most of the printing code. He also added support for English and Metric units. I added the File->Page_Setup where page margins can be specify. --------------------------------------------------------------------------------------------------------------------------------------- Version 2.1 (1997) by Frankie Arzu. Support to load other common airfoil formats found in the UIUC database. (*.dat). --------------------------------------------------------------------------------------------------------------------------------------- Version 2.0 (1997) by Frankie Arzu. Multi Page printing, Station Lines, Able to change camber and thickness. --------------------------------------------------------------------------------------------------------------------------------------- Version 1.0 (1995) by John Garnham. Original Code in Visual C++. --------------------------------------------------------------------------------------------------------------------------------------- MENU DESCRIPTION FILE Menu New, Open, Save, Save As: Loads and Save template definitions and airfoil coordintates. Print, Print Preview: Normal Printing Functions!! Print Setup: Setup printer parameters (Paper size, orientation, etc.) Page Setup: Setup page Margins. You can specify Top, Left and Right margins, as well as an extra Overlapping parameter (Lees than the right margin). The Overlap is useful to align big templates printed in several pages. SECTION Menu Choose: Choose the airfoil to use. Chord: Specify chord lenght. Thickness: Change thickness of the airfoil (% of Chord) Camber: Change camber of the airfoil (% of Chord) LE Balsa: Width of the LE block to use. Skin Thickness: Specify the skin thickness. LAYOUT Menu Foam: Specify the dimensions of the Foam block to use. Thickness is the vertical height of the foam block, while "height" is where the center line of the airfoil will be place from the bottom of the block. Leadins: Specify the length of the LE and TE ramps. WashOut: Wash Out to be use (can be negative to give Wash In!!) Stations: Number of stations to be plot in the template. Wire: Thickness of the wire cut, this parameter is at least the diameter of the wire. To compute it you have to make several cuts in the scrap foam and measure the diameter of the cut when the wire is hot. This is why if you zoom the LE of the template, the lower template will look shifted to the left the same distance as the wire diameter. VIEW Menu Tool Bar: Hides/Show the Tool Bar Status Bar: Hides/Show the Status Bar Section Chord Line: Hides/Show the cord line of the airfoil. Foam Block: Hides/Show the foam block. Leadins: Hides/Show the ramps lines. Stations: Hides/Show the station lines in the template. Text: Hides/Show the text information in the template. Metric: Switch from Metric to English and vice versa. Upper Section: Hides/Show the upper line of the airfoil. Lower Section: Hides/Show the lower line of the airfoil Upper Core: Hides/Show the upper line of core. Lower Core: Hides/Show the lower line of the core. AIRFOILS You can download the airfoils from many places in the internet, I specially recommend the UIUC Airfoil database at http://amber.aae.uiuc.edu/~m-selig/. Preferable you can download .COR format. The database has several file with different formats, all with the same extension (.DAT). Profile can load and recognize the most common formats of this DAT files, BUT NOT ALL. It the program displays crazy things, you know that it did not recognize well the format. All this files are TEXT, so you can edit them in the window notepad.exe program. FOAM CUTING This program was design to help plot the airfoil templates. First you have to cut two lower core templates and two upper core templates. The program will automatically compensate the lower core to take into count the wire diameter. To cut the core, first you have to cut the LOWER part of the core and then the UPPER part!!! Otherwise, the wire compensation in the template will not work OK.
