You're a hero StrikeMax!

I think if a bit of solid reaserch is done of the ectoplasm effects, i.e:

 

- intensity as a function of AOA

- length as a function of velocity and atmospheric conditions

- correct vortex movement over wings and vortex bursting

 

if these are implemented than this would raise the bar to ED and any other sim developer to create realistic ectoplasm rather than the F4 'white streaks'

 

All that being said, anything is better than nothing :)

Absolutely phenomenal! High-G/Alpha vertices and condensation were something I've always wanted to see implemented into LOMAC! I thought that it was impossible and limited by the graphics engine, but I never thought of building it into the aircraft model itself like that!

 

This is absolutely great news, almost as important as the brand new Flanker model itself! I hope you continue to follow through with this particular effect, can you imagine how brilliant it would look when in a dogfight?

 

Keep the updates/screenies coming!

I found some variations of Su-27's vortexes:

http://forum.airforce.ru/download.php?id=2239 (very good photo. Showing two main vortexes of Flankers, in sam time. The wing vortex above the LERX vortex)

 

http://forum.airforce.ru/download.php?id=2237 (the LERX generate the vortex, but not from leading part, just from the rear, closer to wing position.)

 

http://forum.airforce.ru/download.php?id=2243 (the vortexes are rotating to the inner side of vertical stabilisators, this is a really important thing, because the vortexes are able to shake (and destroy) the stabilisators.

 

http://forum.airforce.ru/download.php?id=2241 (the LERX working on own vortexes, but the wing started to generate another one above the surface.)

Most of those pictures do not show vortexes. They show the partial pressure of the vapour overimposing the lower pressure of the dry air over the upper airframe. The config of those effects are highly dependent of the weather conditions. Its also too big and too complex to model in the game and it will certainly look odd and ugly. The LERX condensation is what that hapens more frequently. The one depicted in strikemax's pictures is enough, even if it could be reshaped/repositioned.

[walmis]

what arguments control these vortexes?

[Pilotasso]

Yes it would be nice to have something on the F-15 as well. :D

 

Though unfortunatly it doesnt create much but the usual overwing vapor halo.

It doesnt have sexy LERX's.

 

BTW do these vapor efects shake or something? It would be nice for them not to do it too slowly like guns smoke. They are so slow it looks like slow motion stuff.

[komarov]

Check the films about the famous No.711 Su-37 or the Su-30MKI.

Especially the Su-37 with the long aspect ratio vertical stab. When they do the "Kulbit" or any quick high alpha turn, the top of the vertical stab. shaking in the huge vortex from the LERX.

Ten years ago in the US Navy, the F/A-18C Hornet fleet was went under a big investigation, because this controlled waves from the LERX produce small damages on the vertical fins.

The indian Su-30MKI had a same problem in 2003.

The USAF F-15 too, but the only accident's cause not from subsonic vortex, it was at supersonic speed, but the reason was the waves too.

This vortex generate a low pressure waves on the top of the wings an the fuselage.

what arguments control these vortexes?

 

maybe the same ones that control the leading edge slats? Not sure how he will implement them.

Hi,

Just wanted to stress the following:

 

- I am still experimenting with this.

- The completed one should be animated.

- No argument to controle that in AC model , I am creating them in the same file to get relative positioning/placement. They will eventually go into another file.The same file that displays the Wing_tip vortex.

Which means that the display time window must be a subset of the wingtip vortex display window.the whole span or just partial. No other options.

Which also nesseciates the recreation of the wingtip vortex effect since you can't simply import it and add the LERX to it.

 

As simple as that ( or as difficult as that, don't know) ;)

[some1]

There could be one problem: The file that displays the Wing_tip vortex is probably one for all planes in game (just like the afterburner cone). But I'm not sure about this.

[StrikeMax]

Not in this case, there is one for the su27 left wing and one for the su27 right wing. Infact, there is one for each plane, specific.

[some1]

That's good. Very good :]

 

So the wing tip vortex will also be reworked. Nice.

[Vekkinho]

nfact, there is one for each plane, specific.

 

Does this mean that each plane can have different vortex?!!

 

Wow, this kix ass!!!!:thumbup:

[Merlin555]

hey Walmis. would be great that you follow this matter closely.. mmmm vortex on the Eagle...

[AKULA_OPTIMUS]

Vortex effect?? This can be done in lomac? wow

[pho3nix]

Pilotasso

Most of those pictures do not show vortexes

 

If you look carefully you can see the votexes though the ectoplasm in all images.

 

BTW Komarov great shots, these realy shw the complexity and the combination of airflow characteristics that occur simultanously :)

[Vekkinho]

Cool pics, komarov. Nice research on the matter :thumbup:

[JaNk0]

Sry Strike, i know you have alot to do with projects, but can we get any update?

[Cosmonaut]

I know this is a long shot but is it possible to add flexing wings like in FS9?

[EscCtrl]

If theres an argument for it then in theory yes.

[Disso]

I know this is a long shot but is it possible to add flexing wings like in FS9?

 

I don't think there would be much visible flex. On an airliner yes, but on a fighterjet? I have seen countless videos and the most the wing does is vibrate under high G-loads and pulls, with the most flexing being not worth the work.

[EscCtrl]

yes you can see it - there is a picture of a tornado with its wing bowed an incredible amount. i'll try and find

[Cosmonaut]

You can see the wings flexing on fighters, check out this video;

. The cool thing about this feature would be the fact that you could actually see, from inside the cockpit, the aircraft reacting to the stresses being placed upon it. Although as I said its probably not possible in lockon but hopefully it will be in ED’s next sim.

[p_o_d_2_2]

whats the name of the song in that video?
