..... what this is ?
-
Shinden Kai; I think.
I beleive there were two prototypes; I think one flew. Never saw action though.
-
seems like everyone had a prototype that looked something like that, but never made it to production...probably some fundamental design flaw
Curtiss XP-55 "Ascender"
(http://www.wpafb.af.mil/museum/research/p55-2.jpg)
krauts has half a dozen or so similar designs: BV P.207, Hs P.75, Do 247, Li P.10, etc
somewhat more conventional: Curtiss XP-62 - designed to have P&W Wasp Major engine, armament was to be 8 x 20mm...Jug on `roids:

My book says Kyushu J7W1...
It flew test flew while while Enola Gay and Bocks Car were on the way.
Both look like something out of Rutan's design group.
-
These canard designs were seen as a way to tweak a little more performance over conventional designs. By the time they were being tested jet engines were on the way, offering huge performance increases. So canard designs were trashed.

Shinden Kai; I think.
You are mixed up with the designation for the N1K2-J Shiden Kai "George", a refinement of the N1K1 Shiden.
That's a Kyushu J7W1 Shinden; the J7W2 Shinden Kai was a proposed design variant of the Shinden that never made it off the drawing board (not surprising, since only two Shindens were built before Japan surrendered, and one was destroyed when the factory was bombed) that replaced the propellor and engine with a jet engine.
A comparison of the two aircraft. First, the Shinden:

And the Shinden Kai:
(http://j-aircraft.org/xplanes/hikoki_graphics/shinden_kai.jpg)
Here's a page from a Japanese modelling magazine about a model of the Shinden-Kai that someone converted from a Shinden kit on the premise that the Shinden Kai would be a conversion of the Shinden airframe that replaced the 2,130hp Mitsubishi MK9D ([Ha-43] 12), 18-cylinder radial engine with a 1,984lb. thrust Ne-130 turbojet, otherwise retaining all of the Shinden's tooling (There is some question over whether or not the J7W2 would have retained the same profile as the prop version. The argument that it would not rests on the fact that with the jet engine, there would be no need for the long landing gear as there would be no prop to provide clearance for. Another would be that the intakes would be simplified as there was only the need to feed the jet engine airflow.):

Would have been nice if these were in time for the war.
I bet they were highly unstable, wich would make them great in the hands of a good pilot, but suicidal for an ensign.
-
As I understand it, this design configuration (i.e. rear wing with canards up front) is very stable. It is practically impossible to cause a spin in one, and stalls are basically self-recovering. In fact, this inherant stability may be the reason the designs were not pushed harder, as it may have limited maneuverability. More likey, they were not pushed because they were too unorthadox. They didn't look like what fighter pilots thought fighters should look like, so they were distrustful of the design concept.
-
there is a small private plane with the same configuration in the airport I fly from, looks very cool.
-
Probably the Rutan VariViggen, Animal.

i found something liek that to dl for FS2000 and it handles really well. i foudn a site with prototypes and this was the only 1 i like
-
The J7W1 was in production (not prototype construction, but production for IJN use) , but no production examples were completed before the war ended.
It was armed with four 30mm cannon. Wanna take a guess at what the Japanese intended it to do?
-
Crash in flames with 20 hour pilots at the controls?
Could someone post a pic of the S.A.I S.S.4, the Italian entry to the "Ass-ender" contest. Two .20mm cannon, one 30mm cannon, flew in '39. Prototype crashed, no further work on the design which is too bad as it was the best armed of the Italian early prototypes.

a lot more vari eze's than vari viggens...
