MiG-9 WIP

[Guest capun]

Start with a plane with a performance similar to it as a base and then start modifying it.

 

Pay attention to the animationID's and mesh names. Gear/Wheel/Tire names are critical otherwise they'll sink/jump and explode.

 

Have the 3D Dev give you the ini file with the points helper for the pilot location, muzzle flash, weapon points, wing tip vortices, engine exhaust, etc.

Some surface deflections for MiG-9;

Rudder ± 25 deg

elevators up 18, down 15 deg.

 

Great article in Russian at http://www.airwar.ru/enc/fighter/mig9.html

Thanks fellas/fellattes.

 

This is deep stuff. The collision boxes I could come up with using the external free camera view and watching the debug display position vector numbers. Tables I fully understand, but not the different Cd variables. I guess work down the list. First are the Reference dimensions at the top which I can figure. Inertia, I don't know.

The absolute best (and most expedient way) to create hit boxes is from precise measurements made off accurate 3-view drawings. They will also be of great help when computing out Xmac tables, and also, to ensure correct placement of fuel tanks and engines for damage modeling.

 

Charles wrote a brief tutorial on "guesstimating" the inertia values. You'll find it at Third Wire's site.

Right, I think I have that. I didn't even think of it. Thanks.

[Guest capun]

To be truly correct, You need to have access to the 3D Model to have the Collision Points and Min/Max Extent Positions since they are referenced from the 3DS Max World Center point.

 

In most cases the Wing span is centered in the X-axis, but the Y-Axis (Lenght) may not truly be centered since you are guessing where the CoG is, same applies for the Z-Axis (Height). So the placement of the Model in 3DS Max will affect the Collision Points and Min/Max Extent Positions

 

You can guess by other points defined in the data ini (usually provided by the 3D Designer) like the pilot location, decal location, etc.

[+Timmy 1]

The model is centered in max so the wings have the same relative coordinates - positive and negative values for left and right or vice versa - I can't remember which is which without looking at it.

 

If I need to extract points so Lex can place them in the ini I'll be happy to do it.

[Wrench 9,632]

Timmy: I've 2 versions of the Fargo hangar screen ready, the original which has a pic of 9L trainer, and one without.

 

I'll get them uploaded later today, and send you a link via PM, so you'll have both to choose from.

Timmy, the collison box points would be fine. Thanks.

 

Wrench, those -9 screens, the old ones from long ago? They have been looking for a home for a long time.

[dsawan 615]

Bump! looks good.

[Sgt.KAR98 0]

Great!

Just 1 more MiG to complete the family.

[dsawan 615]

How goes this one?

I've got it mapped - just have to paint the skin when I get a spare minute.

I'm back. Dropped everything SF related. I followed the StrikeFighters Editing guide and got the rather small inertia values below. The other data is from Yefim Gordon's early sov jet book.

 

The inertia values are slug-ft-ft, but isnt everything in the DATA file MKS? Initial testing shows takeoff in a bit under 2km. Yefim says 1.7km. Altitude gain is bad, but that's could be engine detail. The roll is MUCH better now (was waaayy too fast using F-80 data if I recall).

Blessed be your move. I had things come up too, plus, a little SF-esque burnout perhaps.

[Lexx_Luthor 57]

MiG-9 had ten fuel tanks which is a bit deep for a survey sim, and I don't know their exact locations. So I use Pasko's existing three F-80 tanks.

 

Using 0.86kg/l for kerosene, I gave the MiG-9...

 

Fuselage tank -- 1050kg.

Wing tank -- 160kg each.

 

Total 1370kg, divided by 0.86kg/l is volume 1593l which is close to Yefim's 1595l. About 3000lb as seen in game data. I used well less than half that cruising round at full throttle at high altitude in about 3/4 hour, so some increase in fuel consumption are needed.

[Lexx_Luthor 57]

MiG-9 had a pair of 260l external tanks on the wingtips. For now, I'm testing with 75gal P-51 tank (about 360 liters). I eliminated all other weapon stations, leaving only the two -- Left/Right Wing Tip Station

Timmy, please do NOT make external tanks perma-fixed to the external model. I believe these could be dropped if needed.

Edited August 29, 2007 by Lexx_Luthor

[+Timmy 1]

I have the tanks modeled with small pylons but can export them as a seperate lod. The thing I'm not sure about is if I need to export the pylons with the plane or also as a seperate item and then use the weps editor to put them in the game. I'll figure it out but for now I'm focused on skinning so that can wait for a bit.

If looking for shortcuts, you could probably just perma-fix the pylons as part of the model, allowing jettisonable tanks. Its only two, or are they really large? I'm reading through the Yefim book, about 1/3 of it covers the -9, so lots of reading to do. I'll look for unloaded pylons in the pics.

Here is what I came up with for drop tanks and pylons...

You make the Pylons part of the airplane 3D Model, the tanks can be done in their own since they are a "weapon"

 

Your pylons wil be visible or invisible via the ini, if declared properly. They are visible only when you are carrying a weapon load.

What you can do with the ini files is amazing for example you can have two types of pylons in the same space, one larger pylon for bombs/fuel tanks and another for rockets/missiles. Depending on the loadout and with proper data ini entries only one get selected.

 

 

For example, this came from our Meteor F.8

[Lexx_Luthor 57]

Wow. Timmy that's a nice drop tank and sweet pylon.

 

If you do what capun says, update me. I didn't know how this operates exactly. My Yefim book only shows pylons when the tanks are loaded -- no empty pylons in any of the pics.

[+Timmy 1]

Capun - Thanks man, you have always been tremendously helpful and have considerably shortened my model building learning curve, I am very greatful.

 

Lexx - I only have one picture of the drop tanks so I don't know if they are accurate or not but from tinkering with the model I think the pylon has to be that large so as to not interfere with the ailerons. I assure you that I will make a LOD with the pylons and one with the tanks so we can use them on the finished aircraft - I've even already mapped them both...

 

The problem lies in the fact that the real world is taking a rather large chunk out of my buttocks right now so free moments to work on the MiG are pretty much like hillbilly teeth (few and far between) right now. I'm getting it skinned slowly but anything that is going to look decent will take some time - and making a template from scratch takes quite a bit of time and trial and error - sadly, exactly what I'm lacking right now... Once I get the house in reasonable shape I'll be able to finish the MiG and reveal my other project which is about 75% complete :)

[Lexx_Luthor 57]

Finish the house first. I got distracted too the last few weeks. I'm only doing little pieces of DATA file here and there, the easy stuff first. I'm in no rush here, as I can see the steep wall to climb learning this. But it does look interesting, and its stuff I kinda need to learn.
