World War II Nazi Conceptual Fighter “Triebflugal”
The reason this is labeled as a conceptual fighter is because only a prototype(s) and designs were captured after the end of WWII.
The first thing that stands out about this fighter is it’s “wing” layout. The idea was that some power source (rockets/ramjets) would drive it’s three (although mine has four as well as are considerably wider than the real ones would have been, I guess it makes it look LEGO-ized) wings around the fuselage much like a gigantic propeller.
Another thing about this craft is the fact that because of its propulsion system it could not land like a conventional airplane and as such had no conventional landing gear to speak of.
It also little resembles a traditional aircraft, without the wings, being shaped more like a fuel tank or missile. Proposed armament would've consisted of two 20mm cannons, and possibly other supplemental weapons
To better mirror the functionality of the wings I built in pivoting bases allowing the wings to tilt and sit at an angle like the “real” thing.
I wasn’t sure what to put on the back so I embellished a bit with tail lights and a vent of some sort.
I also worked in a functional cockpit that has a little detail (a couple of control sticks) as well as mostly studless detail.
The proposed method of driving the wings was to include ram jets (see rear picture on the end of the wings) at the end of the wings along with disposable rockets to start the process (ram jets can’t function at low speeds so would need a startup system). The result is both a propeller effect as well as some propulsion from the jets. I don't think this would lead to torque problems because of a lack of a conventional engine (if anyone knows please tell me if there would be torque problems). However I'm pretty sure it would have gyrostabalizing properties that would limit its maneuverability in certain directions, like trying to turn a spinning wheel in certain directions.
Although no aircraft ?actually flew? a model was successfully tested in a wind tunnel up to 0.9 mach.
This is the actual launch (and landing) position of the Triebflugal. Once off the ground it would tilt into forward flight and vice versa for landing. One major drawback aside from the issue of the complex engineering needed to even make this concept work was the difficulty inherent to a pilot having to land on something he can’t even see (at least very poorly) because he’s facing away from the surface. Despite its potential problems I like the uniqueness of this aircraft and I’ve never seen anything like it before or since.
I have actually heard of this fighter before and all i can say is nice job...the rotor thing is especially good and so is the tail....nice work....also please check out my mocs i build ww2 planes to------David
Looks nice, and you almost had the name, the "e" and the "i" need to be swithched around. Also, this was not only a concept, but an actual craft. The Allied forces had captured both the plans and the actual craft at the end of the war, so the craft was sent to England where it was taken apart and later destroyed and marked as a "Failed" research project. But any ways, great job!
Interesting design. I'd think with a propeller that large, the body of the plane would be torqued in the opposite direction. In 1951 the Navy proposed a tailsitter project similar to this and awarded Convair and Lockheed contracts to produce concepts. Both companies were supposed two build two prototypes, but each only built one, I believe both of which flew. Neither the Convair XFY "Pogo", nor the Lockheed XFV-1 (refered to as Salmon?) were a success and the program was dropped. The XFV-1 used a three bladed prop that counterrotated to combat the torque problem I mentioned. Ok, sorry for the rant, nice MOC! Peace - Patrick
