Re: [Flightgear-devel] Constant speed props for WWII aircraft using JSBSim
Oops, I didn't actually committed the JSBSim version of A6M2. Now it's done. :-p Please give it a try! BTW, I have two minor problems on this: - small vibration of tail gear. - rotating right instead of left when start taxing. If you have any idea to solve these, please let me know. Best, Tat p.s.

First I tried a default prop configuration generated by Aeromatic, but the propeller pitch was adjusted automatically. So I removed minrpm and maxrpm tags from prop configuration file and the manual pitch control seemed working fine (Thanks to Ron for advice). Technically it's not a constant speed propeller anymore, but the behavior of both propeller and engine is getting closer to the descriptions in some books that I have. However, there came another big problem - too much engine rpm in cruising with lower pitch. I tried to adjust the power table to avoid this happening but no clue. The engine still exceeded way higher than the maximum rpm (more than 2000 above maximum) in the lowest pitch when cruising. Maybe I need to find the proper power / thrust correlations, but it doesn't seem possible to me. As a workaround for this issue, I modified the power table to have higher value in lowest pitch where advance ratio 1.0 even thrust value is zero. This way, it seems working fine - the rpm of the engine stays a bit higher than maximum rpm. But I'm not sure if this is a proper behavior of the constant speed props for warbirds. If you have any better idea, please let me know. If you get interested, please check out A6M2 from CVS and give it a try. The pitch is set to the lowest for climbing. You need to adjust the pitch to maximum in cruising. Though the thrust/power table looks very weird, it's getting closer to zero's behavior I guess. Constructive comments are very welcome. Best, Tat p.s. I'm also willing to simulate zero's manual boost controller in JSBSim. (not sure if it is possible though) - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Flightgear-devel] [ANN] New Eye-Candy
Hi all Tim Moore has just uploaded the wingman code to cvs (thanks Tim). If you want to experiment on a dull Friday afternoon, you will need to update cvs data as well. Then --aircraft=buccaneer-wingman will give you 1 Buccaneer as a wingman, Ctrl-I in runtime will bring up a menu of a small selection of formations. You can add to these with additions to the Buccaneer/Formations folder. --ai-scenario=wingman2_demo will add a further pair of Buccaneers to your formation. The cost in frame rate here is small so add a bit of fun to your flying. Enjoy, Vivian P.S. I have yet to work out how, or indeed if, we can pass the wingmen on MP. - This SF.net email is sponsored by: Microsoft Defy all challenges.

I found, while working on a terrain following/avoidance system for some of the aircraft I've done, that the Nasal geo.elevation(lat, lon) function will return the height of buildings or other structures e.g. bridges located at that lat,lon. There are not any in-built FG scanning schemes/mechanisms though, so you'll have to design and implement one in Nasal to fit your needs. Have a look at the cvs BAC-TSR2 TFA nasal stuff to see the simple look-ahead scanning schemes I've done. Both of the schemes I've used just perform a single track look-ahead scan, compensated for yaw but not for turning flight (yet).

* ricardo freitasfilho -- Friday 15 February 2008: It is usefull if there is a may to get the information of the scenery buildings so we can avoid these building in the simulation. There's no way to query the location of buildings (like in real life :-). But you can check for the terrain elevation at some given coordinate (Nasal's geodinfo(), or the geo.elevation() wrapper), and you can get the elevation of an impact point (see $FG_ROOT/Docs/README.submodels). The latter might report impacts on buildings (fg/osg?), so you could abuse that by launching an invisible, lightweight, and very fast submodel, and check where and at which altitude it lands. m. - This SF.net email is sponsored by: Microsoft Defy all challenges.

And I'm not sure if they collide with static/random buildings. They hardly do with trees. Hmm ... cows? m. Markus Zojer has used this technique for the TFA functions in the B-1B. I had a look at it and experimented with it when I wanted to add TFA to a couple of aircraft I've done - it's a very appealing approach because it's almost like simulating a real radar. I had a play with the technique but hit some problems with it, mainly because the trajectory of the submodels is fixed to the pitch of the aircraft. I found it fine while the aircraft was in level flight but I hit some issues when the aircraft was pitched up or down to any significant degree and in the end I decided to use the Nasal geo functions instead. As I mentioned previously, the geo functions do interact with static buildings and structures, as long as the scanning scheme has a high enough resolution to ensure sampling them - I haven't tried with random objects though - still on OSG 2.2 here and the performance hit when using OSG_DATABASE_PAGER_DRAWABLE=VertexArrays is too great here. I have noticed that pylons are not detected and I would doubt that trees are detected either, presumably because they have no area. The pylons are made with line objects that have no width and the trees, at least in plan, also have no width, so it'll be very unlikely to hit the exact point where they are in any scanning scheme. Adding a transparent horizontal plane poly to the top of these objects probably would make it work, but not only would it increase the render load but also probably introduce more transparency render artifacts and ordering issues.
