FlightGear - Création d'avions et autres / Creation of aircraft and other

I forget to link this discussion. Anyway I received an answer by CEM/rebootl...

As you see, sadly, he don't seems so much interested to continue to work with us. And, as stated, he's developing a new U-2 version with the JSBSim FDM. 

I don't agree so much with that. I have to explain... With different models, you have the opportunity to develop new and different solutions. So that's your decision.  Each file inside our new release will be checked. Credits will be given to CEM of the early development of the project. But here we have developed a completely new mesh design and optimized airplane, with new FDM, and so on. Most important thing our U-2 will be really released with the GPL License, without copyrights inside.

Regards.

Bonjour à tous les gens dans ce forum, Bonjour Helijah

Je suis ici pour poster quelques nouvelles qui s'est passé ces derniers mois. désolé pour mon mauvais français. J'espère que c'est compréhensible ce que je veux dire. Je n'ai pas été très présent pour des raisons personnelles, mais après une longue période j'ai eu l'occasion de reparler à Helijah, et après plusieurs conversations nous sommes arrivés à la conclusion que de poursuivre le projet U-2 était nécessaire d'enlever toutes les mentions de copyright dans le 'archive compressée originale.

Il a donc été décidé de créer un nouveau maillage complètement. Un meilleur 3D model/mesh, et depuis optimisé par rapport à la conception initiale de CEM. Et ainsi fut fait. Je joins à la conversation que j'ai posté sur le Forum FlightGear, dans lequel je communique la décision a CEM, concernant le projet U-2. Je espere qu'un jour CEM, vous êtes d'accord pour unir votre travail à la nôtre. Maintenaint...

New redesignation for the TR-1A; updated with a General Electric F118 engine, improved sensors, and addition of a GPS receiver; 31 converted

TU-2S
New redesignated TR-1B two-seat trainer with improved engine; five converted

U-2E/F/H details

In May 1961, in a little-known attempt to extend the U-2's already considerable range, Lockheed modified six CIA U-2s and several USAF U-2s with aerial refueling equipment which allowed the aircraft to receive fuel from either the KC-97 or from the KC-135. This extended the aircraft's range from approximately 4,000 to 8,000 nautical miles (7,400 to 15,000 km) and extended its endurance to more than 14 hours. The J57-powered U-2Bs were re-designated U-2E and the J75-powered U-2Cs were redesignated U-2F. Each modified U-2 also included an additional oxygen cylinder. However, pilot fatigue was not considered, and little use was made of the refueling capability. The one and only U-2H was both air-refueling capable and carrier-capable.

U-2R/S details
The U-2R, first flown in 1967, is significantly larger and more capable than the original aircraft. A tactical reconnaissance version, the TR-1A, first flew in August 1981. A distinguishing feature of these aircraft is the addition of a large instrumentation "superpod" under each wing. Designed for standoff tactical reconnaissance in Europe, the TR-1A was structurally identical to the U-2R. The 17th Reconnaissance Wing, Royal Air Force Station Alconbury, England used operational TR-1As from 1983 until 1991. The last U-2 and TR-1 aircraft were delivered to the Air Force in October 1989. In 1992 all TR-1s and U-2s (all U-2Rs) were designated U-2Rs. The two-seat trainer variant of the TR-1, the TR-1B, was redesignated as the TU-2R. After upgrading with the F-118-101 engine, the former U-2Rs were designated the U-2S Senior Year.

ER-2 details
A derivative of the U-2 known as the ER-2 (Earth Resources −2), in NASA's white livery, is based at the Dryden Flight Research Center and is used by NASA for high-altitude civilian research including Earth resources, celestial observations, atmospheric chemistry and dynamics, and oceanic processes. Ironically, these were some of the specified "missions" of the original U.S. government cover-up. Programs using the aircraft include the Airborne Science Program, ERAST and Earth Science Enterprise. Landings are assisted by another pilot at speeds exceeding 120 miles per hour (190 km/h) in a chase car.

The following images can explain better:

About the Insignia and patches copyrights:

I think I'm not breaking any copyright! If you look at this page, you will find the list of American Aero Squadrons...

http://en.wikipedia.org/wiki/List_of_Am … _Squadrons

Looking at the insignia of the 99th squadron (The U2 Squadron is just an example) you can read that:

"This image or file is a work of a U.S. Air Force Airman or employee, taken or made during the course of the person's official duties. As a work of the U.S. federal government, the image or file is in the public domain."

http://en.wikipedia.org/wiki/File:99th_ … uadron.gif

This quote is applied to all USA Insignia and patches. You can look by yourself!

In the case of the USAF, the office that keeps all the documentation on patches and insignia is the Air Force Historical Research Agency. And they're free to use, not commercial use obviously!

http://www.afhra.af.mil/art/mediagaller … eryID=5306

To be more clear about this argument I think will be useful to read what Wikipedia says about Public domain, with great attention. Look at the section "Government works".

It says:
"Works of the United States Government and various other governments are excluded from copyright law and may therefore be considered to be in the public domain in their respective countries. In the United States, when copyrighted material is enacted into the law, it enters the public domain. Thus, the building codes, when enacted, are in the public domain. They may also be in the public domain in other countries as well. "It is axiomatic that material in the public domain is not protected by copyright, even when incorporated into a copyrighted work."

link ->http://en.wikipedia.org/wiki/Public_domain

Now I think: WHY we cannot use All of that Insignia and patches into our models if they're Free, and NOT covered by Copyright Law? Just because is from military, or what? I'm not a lawyer but I don't see any violation of the GPL, and I don't think the United States Governement will ask for a copyright violation. If so, most of the airplanes into FG needs to be deleted immediately from GIT. Because I can't believe that you all, asked to every Airline Company the permission to model their airplanes, to use their liveries and logos. And after all if the FlightGear Simulator can't use any airplane, because you never asked the permission to model it to the Companies, so there is no reason to continue to develop this software. I'm wrong? Anyway you model your preffered airplanes and you release that under GPL. And that's more acceptable for you than not to use that Free Insignia (not covered by copyright laws) because someone said that violate the GPL license?

Who said?

Peace and love as usual!

Patrizio

I'm workin on a new version (a totally New 3D model). Is the most updated Lockeed U-2S, just a bit different from the TR-1A:

Real U-2S (last version):

The new 3D model:

Let me know.

Hello guys, Hello Emmanuel,

I saw and checked the entire package, so I get a fly over 78000 ft to test it.  Just Amazing. It seems everything is almost ok, names and authors too.
That permits me to get a fresh breath and more relief.

The U2 is going to be perfect in every side of the development.  There's a "but" my dear Emmanuel, cause you used a wrong model full of errors.
My mistake as usual!!! When I sent you the link it was late, and I was really tired. Please forgive!
So there was a lack of attention and I confused that files.

The good one is here:

http://sites.google.com/site/cobe571dat … -v.2.blend

This evening I worked on the panel and there's a good development on it.
Just to speed to the max the good work I used (with his permission) many instruments made by Emmanuel.
As suggested I get them by 1950/1970 Era.

Get a look:

(Not finished yet)

Hope you will like, suggestions are really appreciated!

Friendly

Patrizio.

Hello 5H1N0B1,

The original idea was to create two panels. The old one, and a the new one with digital display.
Right now I'm using this picture as reference with many difficulties because I'm a really noob with FG:

As you see there's alot of work to do...

Patrizio

Hello Didier1963,

as explained I used most of the parts from the original project by CEM -> http://wiki.flightgear.org/Lockheed_U-2S
Then I added some more stuff, and tried to upgrade the mesh. About that Helijah is giving me fists on the head every time he finds an error.
But as Helijah explain: "There is a very big difference between making 3D models for calculating images, and 3D engine for "real time"

Btw is ok... In this way I learn from my errors
And yes We're looking for approval by CEM to ultimate the U2-S and join the strenghts.
As Helijah said his work is very interesting!
Hope that will clear any doubt.

Regards

Patrizio

Hi all,
I need to resolve the topic and what asked 5H1N0B1 and C-Vall about the two versions of the "same" model. Generally into modeling I use alot of free parts from many other free models. I'm not a purist! This bad approach is very different for example from Helijah, that create 100% of vertices and code of his own work into modeling, and FlightGear 3D Engine, with the respect of the GPL License. Mixing different parts, I obtained a new mesh from a  lowpoly mesh  derivate from others U2-S models adjusting proportions and dimensions. Improving a little the Wings and adding small parts, and textures made with GIMP. Now I'm still working on modeling of  the internal of the cockpit: Instruments. Cloche. Pedals. Switches, etc.

As Helijah said I added other parts and vertices to another mesh that was already on The Official FG Forum. That's right! So I wrote a message into the dedicated page on FG forum linking to this discussion and the Early, and Very Good Development of the U2-S made by Helijah and You All for the most, Here into this Forum! I Suggest a collaboration with the original Author, with the goal to ultimate the U2-S finally, and introduce it to FlightGear officially. All this, into a more confortable GPL License that respect all Authors
