Ariane V AXM 1:96 version – Décollage!

This is my 1:96 scale version paper model of the beautiful Ariane V rocket from Arianespace.
All the photos are from my prototype models, therefore slight differences will be noticed if compared to the final product specially in the color of the model, which has been corrected. Special thanks goes to my friend and talented modeler Jasper Huizinga (Paper Kosmonaut) – well known in the Papermodelers community forum, for his advice and positive feedback regarding the color I originally chose for the Ariane V model. He assisted me in managing and correcting the color. At the time of this post, all the Ariane V models already released by now, have had their color corrected from the original color. Thanks PK.

This post will not cover in detail the technical aspects about the Ariane V and its components. That can be obtained online. I will only talk about the paper models and its details.

A little information about the Ariane V variants:

  • Ariane V G           1996 to 2003
  • Ariane V G+        2004
  • Ariane V GS        2005 to 2009
  • Ariane V ES        2008 to present
  • Ariane V ECA     2002 to present

The ES and ECA versions are the current Ariane V configurations to date.

Because of the external differences, I have designed 2 models for comparison, what I called the Old and the New Ariane V.

The Ariane V anatomy

Basically, the Ariane V consists of a Center Core, 2 strap on boosters called EAPs and the payload fairing.

Here is a side by side view of the Core showing not only the difference in color but the umbilical lines. The Old Ariane V core (right) had a brownish color and the umbilicals originally consisted of 5 lines. The New Ariane V core (left) is grayish with only 4 lines in the umbilical area.

Strap on booster difference. Notice the lines and the marcated segments. Old (left) and New (right)

Notice the Old (left) and New (right) CNES logo.

Bottom view of the strap on boosters differences. The main difference here are the number of hydraulic tanks on each SRB (EAP). The old version (left) had 2 on each EAP, while the New version (right) has only one tank.

Another difference is the Arianespace logo that has changed throughout the years. Since the early flights, the Arianespace logo had a cursive font and the logo’s arrow pointed to the left.

Then the font changed but the arrow still remained pointing to the left.

On Jan 1, 2009 Arianespace formally inaugurated a new graphic style, providing a corporate identity refresh. It incorporated the “Service & Solutions” motto as an integral part of the logo. In addition, the logo’s stylized arrow -which represents a launcher’s flight trajectory from French Guiana- has now a new orientation to the right, reflecting Arianespace’s forward looking business strategy and symbolizing the introduction of Soyuz and Vega at the Spaceport.

The last mission that carried the old logo was Ariane V Flight V-186 Hot Bird 9 mission and the first mission that carried the new logo was the Ariane V Flight V-187 Hot Bird 10.

Another difference is the engine section. The old version had the old Vulcain engine, while the New version has the upgraded Vulcain 2 engine.

The Models

For the Old Ariane V, I chose to design missions 503 and 504, being the 3rd and 4th Ariane V missions, because of the difference in the engine section. Historically, the 503 mission was considered the last test flight of the Ariane V. The 1st mission 501 was a failure ending in an explosion of the vehicle during liftoff and the second mission 502 was a partial failure.
All 3 missions 501, 502 and 503 had the original 2 helium chamber reservoirs in the engine section.

Notice the 2 rounded Helium reservoirs on the left side of the engine section. The larger rounded chamber to the right is the Liquid Helium container.

Mission 504 was the First successful commercial flight of the Ariane V. In contrast with the previous 3 missions, the engine section on the 504 vehicle only carried one Helium reservoir.

The following photos are from models 503 and 504.

Difference in the fairing for both missions.

Mission 503. Notice the old Arianespace logos on both the core and the old CNES logo on the EAPs.

Notice the red rectangular area on the left EAP. The photo on the right is from the back of the vehicle showing the second red rectangular area on the same left EAP but on its back. During my research I found nothing regarding the significance of this red rectangular patch on the EAP. Because this was still a test flight, I assume this could have been a sensor placed on the EAP. Also, the core of the 503 mission had several lines on its circumference, with the assumption that these were also sensors for this last test flight.

More detailed photos.

Closeup of mission 503 fairing. For the mission logos, I couldn’t find the real insignia for the MaqSat 3 (black rectangular logo). The artwork is mine and is based on a low resolution photo of the logo.

Mission 504

For the New Ariane V models, I chose ATV-1, ATV-4 and Galileo VA-233 Sats missions.

Few of the fairings from the New models.

Ariane V ATV-1 had the new EAPs but with the separation lines on the boosters like the old version. Also, it still carried the old Arianespace logo.

Ariane V ATV-4 had the new EAPs with no separation lines on its segments and carries the new Arianespace logo.

Another model is the Galileo FOC M6 mission that carried the Sats 15, 16, 17, 18. This is the ES variant, which is a more current Ariane V fairing configuration.

Another fact about the Ariane V are the covers for the EAP upper attachments. These white cover structures are in between the Core Interstage section and the Upper portion of the EAP. Photos show that these structures are actually separate pieces that fall off during launch.
For the model, I designed a one piece that snaps in place between the Core interstage and the EAP.

Putting it together

You have the option to glue the EAPs (boosters) to the Main Core, but these parts have been designed to snap in place.

The photo shows how the top section of the Core interstage and EAP are joined. Notice the little rod in the triangular face on the interstage. That is a small portion of a cotton swab. The EAP does not need to be glued to the core. It only sits in place.

The lower EAPs attachments also can snap in place inside the small triangular boxes for each strut.

The manual shows more pictures of this area.

The instruction manual shows the assembly photos for all these models with the exception of the ECA.
Feel free to send your questions or comments regarding the assembly of the Ariane V model. I am aware of the limited information from the manual but the photos speak for themselves.

Next: On my next post I will talk about the Ariane V ECA version, the VA-236 Mission. This is the fairing configuration that has the longest fairing section.

  1. Great to see all those well documented and researched models. Another fantastic section in your already outstanding range of models. Glad to have been of a little colouring help.
    Really, the models look amazing.

  2. Hello,
    Thank you for this amazing detailed Ariane model !

    I was wondering, what kind of paper are you using to wrap the helium tank located on the engine section ?

    Merci encore !
