He, he, just to be a little pedantic.. it's not my simplification and only about 20 pages are devoted to the subsonic flight region, the transonic takes about 1 page and admits a lack of understanding in this area and section C is supersonic stuff which is a much more complex region which we will ignore for now. And then a bunch of tables and graphs showing the results for each section, some really good data to help create/tailor the aero coefficients. So the problem is not all that daunting and thank you for the excellent reference source. The goal is to provide a reasonable set of stick force numbers that can be fed to a control loading system (hydraulic, electrical, pnuematic, whatever) that will give the pilot a good feel for what the aircraft is doing within the subsonic speed envelope; i.e., < M=0.9 > Hard coding this would be not a good idea - much better to add code to > JSBsim so that it can be built up with parameters from the XML file in > the > same way as the main body forces (Lift, Drag etc). > Agree, that's the idea, the calcs are in JSBSim the data is loaded in from xml files John ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
