Re: [Flightgear-devel] constant weather conditions
Is there a way to keep the weather conditions constant? So either there is no wind at all (which would be preferred) or there is a constant wind from always the same direction (even if I quit a FG session and open a new one). This should give you constant zero wind conditions: fgfs --disable-real-weather-fetch --wind=...@0 At least for the CVS version. Weather generation has changed since the last release and AFAIR behaviour was different some time ago when the weather scenario generator overruled the command line options.

If you want to replay the flight using data you've written to an output file you probably want to add --fdm=external to your command line. This will disable the internal flight dynamics model. Also make sure the input section of your configuration file matches the output section to be sure they use the same properties for both directions.

The current simgear cvs version doesn't compile for me either. I'm on fedora 11, with gcc 4.4.0. I've tried with both osg 2.8.0 (system version) and osg trunk.

This allows one specify OpenGL attributes, including shaders, in .eff files. For the moment these are only associated with terrain materials. The default effect for terrain has a shader that does per-pixel lighting, with a fallback to the traditional pipeline if a system doesn't support shaders. This effect is in Effects/terrain-default.eff. Also, you can disable the use of shader effects with the property /sim/rendering/shader-effects. In the coming weeks there will be more documentation and examples, as well as effects for models, of course. Let me know if anything breaks, I was awaiting your changes eagerly, but I'll have to admit I won't be able to build a win32 binary before I go to my holiday location. The main problem I am facing is that simgear::props::BOOL conflict with a BOOL typedef inside windows.h ( same for INT, LONG, FLOAT DOUBLE ). It's ok to use the fully qualified name, but the using namespace simgear::props directive creates an ambiguity. Second one is that the dependency on SGVec3 type inside props.hxx needs more that forward declarations, and that creates a lot of problems to include SGMath.hxx inside props.hxx. I will try to address that when I come back.

This compares pretty badly with the B-29, which only took a max of 45 seconds to stabilise. The YB-49s weren't fitted with autopilots though, which would have helped. The B-2, of course, is fitted with a modern FBW FCS, which controls the split aileron airbrakes to keep the yaw under control. Incidentally, Edwards AFB is named after one of the YB-49 test pilots who died in a YB-49 crash. I have some comments based on some of the UAV work I've done using smallish (7-8' wing span) fying wings. This in no way makes me an expert in flying wing aerodynamics! :-) We started out with winglets because this is how everyone builds RC size flying wings. http://baron.flightgear.org/~curt/UAS/Malolo1/2007-12-12-C/IMG_22 17.JPG As an aside, this airframe was designed to be waterproof (marinized) and lands in the water next to the boat: http://baron.flightgear.org/~curt/UAS/Malolo1/2007-12-12-C/IMG_22 34.JPG http://baron.flightgear.org/~curt/UAS/Malolo1/2007-12-12-B/img_52 61.jpg We flew the next prototype (with a much larger and more blended center section) from a NOAA research ship several hundred miles north of Hawaii about a year and a half ago. http://baron.flightgear.org/~curt/UAS/Malolo2/20080331-Malolo2-La unch-2/target2.html (This is a sequence of pictures so you can click next/prev if you want) Then we had a stability break through. We moved the winglets inboard to the wing roots and our yaw stability improved dramatically. http://atiak.com/ATIResolutionProductSheet102108.pdf I see that the YB-49 added 4 sets of very small vertical stabilizers inboard, however they seem very small to me. I think if they would have made the vertical surface area larger and closer to the centerline, they would have substantially improved their yaw stability. Oviously those engineers were just a bunch of hacks. :-) But from looking at the various designs, I think their must be a desire to have *just* the wing and nothing else. Tail-less appears to be the goal, and a vertical stab is part of what we'd call a tail. Conceptually, with no vertical surfaces, the wing is largely free to rotate and could fly like a discus or a boomarang. Even winglets at the wing tips offer a lot less yaw stability than I would have expected. They real key observation is to move the vertical stabilizers in as close to the centerline as possible. This locks your heading in and helps the wing track. This idea shows up in other RC designs ... there's nothing new under the sun ... http://www.hobby-lobby.com/f-27c_stryker_rtf_electric_plane_85561 _prd1.htm http://www.newcreations-rc.com/Products/thumbs/imd5123%5B1%5D.jpg Simply moving the winglets inboard turned our design into an *entirely* different airplane. We couldn't fly inverted before (it would just to a negative aoa stall and fall out of the maneuver.) Now we can fly inverted, outside loops, faster rolls, and the aircraft tracks much better. We still have a lot of forward nose side area though so we do get some adverse yaw in turns. Flying wings are really strange beasts to get your head around, but I think the key to success is to add sufficient vertical stabilizer area close to the centerline of the aircraft. Regards, Curt. Hi Curt, I remember following your Pacific cruise with the Malolo, and also how you found that moving the winglets inboard to the wing roots improved directional stability. The reason that the small vertical stabilisers were added to the YB-49 was to compensate for the vertical area that was lost when the props, and more importantly, their fairings were removed; the propshafts and props were located well above the trailing edge and were faired down to the upper wing surface, providing appreciable vertical surface, but the jet tailpipes exited through the trailing edge. Northrop wanted to redesign the airframe to take the jets but had to make do with using uncompleted XB-35 airframes, hence the need to compensate for the lost vertical area. In the end they actually increased the vertical area by extending the fins below the wing as well. I suspect that a single vertical stabiliser on the centerline would have been the best solution but that, once again, would have required a redesign as the tail fairing, as originally designed, wouldn't have been structurally strong enough to support a fin; in the original design the tail fairing just housed the rear guns and the observer/rear-gunner position, so structurally, all it had to do was support the weight. With your models, which don't rely upon internal frames for strength, it's relatively easy to relocate

I suppose there are different philosophies of error handling, but having a hard crash is not my personal favorite. I like the idea of silently creating the property if it doesn't exist ... that is the way so many of our other systems work. If you have a nasal script that writes some output value and a gauge that displays it, if there is a typo in the gauge property, this will get created with zero or null value. Presumably a person would test their data logging before deploying it and would investigate why one or more channels is reporting zero. Perhaps another option would be to throw an exception if the property doesn't exist, which would presumably be caught somewhere and an appropriate message displayed. but I really don't like it when user generated configurations can produce hard segfault crashes with no error message other than segfault or bus error.

Hi Ron, I don't really have a clue when it comes to YASim, but I started a quadracopter in JSBSim awhile back... I found your Quadcopter-model 2 days ago and tested it a bit, but I think the flight behaviour is quite strange. I read that YASim is used to create helicopters and as far as I understood it is not really possible to create a realistic helicopter model with JSBSim. Besides that, all helicopters I found for FG are made with YASim. Please correct me, if I am wrong. Maybe I should have asked earlier for your help, but I have found your model when I nearly finished with my own. Before I started I searched the forum for quadcopter, quadrocopter, Mikrokopter, X-Ufo and Microdrone but found nothing. That is the reason why the forum-title and the subject of this mail are that long :-).
