The rewrite gets around many DOS hardware limitations so you can use the software on modern machines, but does not do anything to make the user interface work like a windows program should. The functionality seems pretty good, but I am still working through the reports. Error messages are cryptic. Installation was simple with no problems.
The software works much like an encapsulation of its DOS predecessor. The main screen that appears to show a design flow through a series of modules just launches each module; there isn't any programmatic connection. The modules are pretty simple front ends to text files on which the calculations are performed, reports generated or graphical screens drawn. Some modules use DOS box dialogs to prompt for values, others allow editing of tables of values that are easier to use. You have to know what you are doing because there are a lot of parameters to enter and few are defined. None are well defined, so read up.
Even the tables work like a DOS program. You edit one cell at a time and click a button to update the file. Its not like a spreadsheet where you directly edit as many cells as necessary and then save the file. Multipage tables do not scroll; you click a button that puts up the next set of columns. My monitors are portrait and these buttons overwrote each other, but were still usable.
The design layout module lets you build a wireframe model parametrically, without having to spend a lot of time with a CAD tool. I built a simple transport aircraft in a few hours; much of the time was spent figuring out how to use the somewhat awkward interface. You do not directly manipulate any part of the model. You cannot grab things to stretch, rotate, and move. The module accepts commands in a variety of ways, then redraws the screen.
The module knows what wings, tails, fuselages, etc are so you don't have to spend a lot of time doing CAD work. As long as the configuration you want is supported, it is very easy to make the conceptual layout. You initially define a part using the text file interface, then the module draws it on the screen.
To edit a design you select an entire part or parts by double clicking names in a drop down menu, which also works like it was made for DOS. Then arrow keys move the selected parts, redrawing the screen after each keypress. You can also use the mouse, but it only uses relative motion and I found it more difficult to get right. To change the curve of a loft line you click on the line and move the mouse to where you want it to go. The screen doesn't redraw until you release the mouse button, so you have to guess where the line will end up.
The software does save time, and it asks for everything it needs so you don't accidentally ignore something. There is no module to module update as in the professional version, so you have to copy relevant info. The author calls this a feature to help students learn. There is also some allusion to reduced accuracy, though this is not further explained.
The author wrote the first version of this software decades ago, became comfortable with the console interface after practicing for twenty years, and sees no need for anything easier for others to learn. It doesn't matter to him that this style was dead before any student now needing this software for school was even born. He says as much. So five stars (so far) for functionality, and zero for interface.
RDSwin is a great software, no matter what anybody else says. It has it's limitations, and these are due to the fact that Mr. Raymer works on this by himself, without lots of funding and a huge team. Of course it's not going to look like high end 3D design software like Autodesk Inventor or Maya or 3Ds Max. And it doesn't have to.
RDSwin is a low-impact program that gets the job done. It leads to tremendous time savings and makes the conceptial design process much easier.
Airplanes can be quickly designed via built-in functions. They can quickly be manipulated and iterated on, which permits quick analysis of several designs. Calculations are automatically made by RDSwin, using the methods and formulas provided in Raymer's book "Aircraft Design".
RDSwin greatly improved my experience when I was doing aircraft conceptual design at the undergrad and grad levels. Industry insiders love it and know how much easier it makes life for them.
If you are into aircraft conceptual design, you should get this program. There is none other like this.
On January 10, 2012, free Open VSP was released as an open source project by NASA, [...]
Open VSP is a parametric aircraft geometry tool. Open VSP allows the user to create a 3D model of an aircraft defined by common engineering parameters. This model can be processed into formats suitable for engineering analysis FEA and CFD. The output includes Aerodynamics performance as well as mass properties (Aircraft C.G location, Ixx, Iyy, Izz........etc which is good for stability analysis). Moreover, you can set and activate slats and flaps deployed for landing or takeoff position, and analyze the aerodynamics performance and export model file for further CFD analysis.
As such I give RDS win only one star just for Extended SAWE8 Group Weight Statement Component Categories
