The Mikoyan-Gurevich MiG-8 Utka was a Soviet experimental aircraft. The aircraft was designed and built in 1945 to test the novel canard configuration, and in particular the stability and handling of the canard configuration in conjunction with swept wings. The name Utka was a direct translation of the French word "canard" ("duck").

The canard configuration has benefits in a jet-powered aircraft as it leaves the rear of the fuselage clear of interference from the jet's exhausts. To test the concept the MiG-8 was powered by a Shvetsov M-11 five-cylinder radial engine, with a pusher propeller. It also used a tricycle undercarriage, the first used by the design bureau (OKB).

The Utka was modified to test a variety of configurations; it was used notably as a testbed in developing the swept wing of the MiG-15. It was then used as a liaison/utility aircraft for many years by the MiG design bureau. Being made of wood and fabric, it was very light and reportedly a favorite among MiG OKB test pilots for its docile, slow-speed handling characteristics.

Hi,


here is early drawing to MiG-8 Utka,compare with the built one,note the
different between vertical tail surface locations.

In 1953, Air Trails (or Air Progress?) posted the attahced drawing, the only time I saw such of the Utka.

Splendid. Utka's nice at any rate, but the sight of an armed Mentor is a rare treat!

Don't know the context of that picture, but if the Utka really would have taken over a
similar task, as the good old Po-2 in the Soviet airforce ( http://www.military.cz/russia/air/mig/Mig-8/mig-8.htm ),
the USAF may have encountered the same problems, as in Korea, fighting such slow
aircraft. An armed trainer could have been a good solution.

Or maybe Grumman, before they designed their (suppremely ugly) floatplane, the DUCK ?

(restrain from posting Monty Pythons Holy Grail videos related to witches and ducks. This is a serious thread).

Is there also an influence from the Junkers EF-128 for the vertical tail solution?

First flight of the Utka was late 1945 and from my understanding certainly enough time to adapt the findings from Junkers projects, which the Soviets found in Dessau and other place in 1945. What do you think?

Development started in February of 45 and first flight was on the 13th of August. Does that really seem like enough time?

Then you have the direct contemporaries; XP-55, Shinden and SS.4. All of a similar configuration and all with a similar vertical stabilizer arrangement. This was hardly unique to Junkers.

Lastly I dont think the engineers at Mig would have been foolish enough to test this on the Utka. The pusher engine right behind the wing changes the airflow over the wing radically. It'd be worthless to test the fence like behavior of these verts for a jet aircraft by doing flight tests with a piston one.
