After completing my Orion EFT-1 1:96 model, the Delta IV 1:96 rocket model is finally here. The EFT-1 became the first Delta IV paper model released at my site and now a whole collection of Delta IV models is waiting.
At the time of this post, all the Delta IV Heavy variants are available, but I will deliver more Delta IV from the Medium variants as well. A lot of research was put into the design of these models. It is noticeable that mission by mission, the Delta IV had different coloration bands along the length of its boosters, and this fact is well represented in my models.
This photo is from my prototype Delta IV Heavy model and shows the main parts of the model.
Notice the lower CBC attachments. These pins will go inside the openings on their counterparts.
Here are the details for the upper attachments.
The Delta IV Heavy model has three similar boosters called the Common Booster Cores (CBC), each one powered by a Rocketdyne RS-68 engine. The CBC is of a constant 5 meter diameter.
The boosters are attached side by side. The central booster has the 5 m diameter second stage interstage attached at the top and this one has the payload fairing. There are two payload fairings for the Delta IV Heavy, one is a standard long fairing bisector version and the other is a Boeing built Titan-derived Longer aluminum trisector fairing. This is mainly the configuration for the Delta IV Heavy version.
The Medium variant consists of one single CBC with either a 4 or 5 m diameter second stage interstage.
The Medium also has Solid Rocket Motors that can vary from 2 to 4 SRMs, therefore the so called Medium + (4,2), (5,2) and (5,4) configurations.
Delta IV was primarily designed to satisfy the needs of the US Military.
Here at details of the engine section.
These are photos of few of the Delta IV models available at my site.
And here is the first ever Delta IV Heavy, the DemoSat.
On a new post I will present details of the Delta IV Medium variant models.
