Welcome to War and Tactics!    War and Tactics Forum is currently undergoing some modifications that might disable features you are used to. This is unabvoidable as we have to update the forum engine to a new structure that is incompatible with many of the features we had used so far. The good news: WaT will be more secure and stable, and most of the features we uninstalled will be a natural part of the new structure anyway. For the rest we will be looking for solutions.

Don't know anything about this one, cant see any markings but given the lack of in takes I am assuming it is a rocket powered design and possibly Russian as they did a lot of work in that area.

I do  not know the exact model, but you are probably on the right track: It is a German predecessor to the OKB2-346 (http://www.astronautix.com/craft/346.htm) and the Biesnovat 5-2 rocket plane, the DFS 346:

It had been taken from the Russians to OKB (the German technicians also) and got throughly tested there. The pilot was lying in the front and could separate the glass cupola to bail out, here some more pix and data:

Span: 9 meter
Masse: 5,2 tons
Vmax reached: 1100 km/h, it was supposed to reach Mach 2+
Engine: Walter HWK 509 (modifiziert) mit 39 kN (4000 kp) power.





Cockpit:





Hope that helps,

should I see this as a 'flying bomb' and why is it hanging on a B-29?

B-29 in Russian lease from the USAF?

No and yes. Follow the provided linky or google the model name printed in bold: DFS 346.

The DFS 346 (Samolyot 346) was a German rocket-powered, high-speed research aircraft of World War II. It was designed by Felix Kracht at the Deutsche Forschungsanstalt für Segelflug  (DFS), the "German Institute for Sailplane Flight". The prototype was still unfinished by the end of the war and was taken to the Soviet Union where it was rebuilt, tested and flown.

The DFS 346 was a parallel project to the DFS 228 high-altitude reconnaissance aircraft. While the DFS 228 was essentially of conventional sailplane  design, the DFS 346 had highly-swept wings and a highly streamlined fuselage that its designers hoped would enable it to break the sound barrier. Like its stablemate, it also featured a self-contained escape module for the pilot, a feature originally designed for the DFS 54 prior to the war. The pilot was to fly the machine from a prone position, a feature decided from experience with the first DFS 228 prototype, mainly because of better g-force handling and aim of reducing the fuselage cross-section as much as possible.

The 346 design was intended to be air-launched from the back of a large aircraft, the baseline being the Dornier Do 217. After launch from the bomber the plane's Walter 509B/C (ZhRD-109-510) engine, which consisted of two superimposed combustion chambers, one above the other, with the lower unit of 400 kg (880 lb) thrust for cruising and the upper unit used only for takeoff, in a so-called "sharp start" directly from the ground, or for short periods when the maximum thrust was necessary, would accelerate the craft to proposed speed of Mach 2.6 and altitude of 30,500 meters, at which point the engine would turn off. In an operational use the plane would then glide over England for a photo-reconnaissance run, descending as it flew but still at a high speed. After the run was complete the engine would be briefly turned on again, to raise the altitude for a long low-speed glide back to a base in Germany or northern France.
