ARADO E.395 model kit development

 Outline

 

Similar in apearence to the Arado 234, the E.395 was a design proposal by Arado for the Strahlbomber competition [Hitler's 'Wonder Weapon' Bomber Projects Luftwaffe Secret Bombers of The Third Reich, by Dan Sharp]. As such, it was both longer and had a greater wing span. 

 

Two different and interchangeable wing design were proposed, a straight wing and a crescent version. 

The design proposal outlines two different engine configurations; with HeS 011 or Jumo 012. Drawings seem to depict a four engine configuration with HeS 011's with a total thrust of approximately 50kN. That value would be reached or exceeded with only two Jumo 012's. Leading to the conclusion that only two Jumo's were planned, despite the lack of information in primary sources to confirm that assumption. Only one drawing shows the Jumo version. But that sideview does not visualize the number of engines.

Engines

Only little information is available on the Jumo 012 engines. This Jumo engine configuration is the most interesting one however. There are only a handful of aircraft designs planned to use this engine which was in it's initial planning phase. Development of the engine was continued after WW2 in Russia.

General layout

Overall layout of the design is assumed to be similar to the 234. A good source of information is the 234 handbook. 


Images of frame 4 and 15 are displayed below (Source: 8-234 B-2 Flugzeug Handbuch). Frame 4 also serves as the back wall of the cockpit and contains a fitting for the nose landing gear.

The image below shows an original drawing of the E.395 (slightly enhanced/ Jumo version).

Landing Gear

Due to it's similarities with the 234, it can be assumed that many other design characteristics can be directly applied to the E-395.


The nose landing gear is moved by two hydraulic actuators and suspended with a central spring. This spring cylinder is placed in the direct compression load path of a support rod connected with a rotational joint. If extended, this rod/spring arrangement is pushed through and rotates into coaxial alignment thereby taking up a major portion of the impact loads.

The retracted nose landing gear forms a compact arrangement.

The main landing gear leg is connected to the fuselage with a swivel axis. Attached to the swivel axis is a cantilever. Hydraulic actuators use the cantilever to create a rotational moment that actuate the main landing gear leg.

In contrast to the Arado 234, the E.395 was planned with a two man crew.

The EMW A-6

von noreply • 11 Feb., 2023
The EMW A-6 looks definitely cool enough to justify making a model kit for it. And as far as I know, there is no 1:48 scale model kit on the market currently. Some information from the www.nevingtonwarmuseum.com:

Leckere Kekse backen

von Kristian Zimmermann • 10 Okt., 2020
Damit Eure Kekse mit unseren Backförmchen so richtig gut funktionieren haben wir für euch ein paar Tips zusammengestellt. Vorab einmal das Rezept: 100 g Butter 50 g Puderzucker (kann dem eigenen Geschmack angepasst werden) 30 g Ei 200 g Mehl Die Mengen können unter Einhaltung des Mischungsverhältnisses erhöht werden. Zunächst wird der Puderzucker mit der Butter vermengt. Danach wir das Ei hinzugegeben. Anschließend wird das Mehl untergehoben. Wichtig: Damit der Teig die richtige Konsistenz erhält sollte er gekühlt werden; ca 30min im Gefrierfach oder 1-2 Stunden im Kühlschrank.

NG-2 PATHFINDER; full auto

von Kristian Zimmermann • 07 Feb., 2020
The PATHFINDER is essentially based on the standard NG-2. But it features a full auto mechanism, voltage indicator and safety catch. Max fps is 130, the rate of fire is approximately 900darts/min.

NG-3; our first rival blaster

von Kristian Zimmermann • 07 Feb., 2020
For this blaster we had to iterate ourselves through 17 different versions. Most deisgn solutions implemented on half- or full length darts where not applikable due to the different type of ammunition. Lets quickly dive into the main design drivers of this blaster.

The NG-2 GOBLIN

von Kristian Zimmermann • 05 Feb., 2020
The NG-2 GOBLIN was designed in 2019 and basically follows the design philosophy of the original NG-1. But, as always, you learn. So the NG-2 was an effort to reduce the overall complexity of a blaster while optimizing it for easy printing and quick assembly. After all, 3Dprinting is rather scalable by simply investing in new machines. However, post processing, assembly, testing and shipping quickly become bottlenecks in production.

What materials do we use and why

von Kristian Zimmermann • 05 Feb., 2020
We use 3D printers to produce our products. There are different types of printers and countless different processes. We have specialized in what is sometimes revered to as FFF (fuse filament fabrication). The process is rather cost effective and uses a simple process of depositing a thermoplastic material layer by layer. 3D printing technology used to be locked down by patents for decades, limiting the technology to large and costly machines. Once those patents ran out, a new generation of desktop printers started to emerge. These machines are rather simple in design, but manage to output parts with astounding quality. Also, due to the small investment costs, the process can now be parallelized which has a profund influence on production costs. At the core of all this, is the material. After all, it is the material in combination with a specific design that enables a desired functionality. And today, in 2020, PLA or 'polylactic acid' is one of the most widespread materials in desktop 3D printing. PLA outperforms almost any other material in this category in terms of strength and stiffness (yes, those are two different things ;)). An interesting comparison is published by simplfy3d here . This is especially true if we take into account the directional dependency of the material properties which is introduced by the FFF process. Out of plane strength, i.e. layer adhesion, suffers greatly for most materials. The overall knock down for PLA is relatively low.

Blaster overview

von Kristian Zimmermann • 05 Feb., 2020
The number of blasters that we have created and their derivatives is steadily increasing. I have hence decided to create a little overview, which you can find here . I will add more information over time, in an effort to answer as many questions as I can.
