There's a model of the
Tachikawa Ta-Go on
Czech Master Resin - 1/72 scale

in their WW II aircraft (1939-1945) series

No.83

Well, they didn't think of kamikaze aircraft with the Fugaku project, but of something useful in a prolonged and repetitive campaign to divert US resources in building an air defense network in the Western States. Even the attack on Panama using the I-400 subs wasn't initially suicidical. The actual use, although aborted, at the very end of the war indeed was...but was accidental; to build such a large and complex weapon to use in a one-way trip would have been a waste of resources. Even kamikazes used worn-out airframes, BTW.

 

[Skybolt]

One of the different projects lumped together under the "Fukagu" name.

[Tophe]

The twin-fuselage ones are the Tachikawa Plan 2 & 3 (Dai Ni An & Dai San An), see my book Forked Ghosts. (free at http://cmeunier.chez-alice.fr/Free_EoFG_MV.htm )

 

[Justo Miranda]

Hi Tophe,

Many thanks for helping me classify this “bipoutre”l.

All the best,
Justo

 

[Justo Miranda]

Hi,

Could anybody help me identify these projects?

[Edit - oops ... typing while asleep! :-[ ]

Number 5 [Escanear0005.jpg] is the Nakajima G5N.

I'm guessing that Number 6 [Escanear0006.jpg] is the Mitsubishi D3M1 [similar to Nakajima D3N1 but note rudder shape and canopy frames].

 

[Pepe Rezende]

Number six is the D3N1:

Hi Miranda

The flying boat could be a Kawanishi H11K ,

and the twin engined aircraft a Tachikawa SS-1 .

Swallow.

 

[Nick Sumner]

1 and 2 look a bit like a J2M follow on? Number 3 looks terribly French.

Sorry I can't add anything more helpful. :-[

 

[Jemiba]

" Number 3 looks terribly French "
But it isn't a Breguet Br.695, I think. There are some small,
but important differences.

(from http://membres.lycos.fr/wings2/3vues/3vues.html)

 

[Apophenia]

1 and 2 look a bit like a J2M follow on?

Number 2 as a Raiden follow-on makes sense. The J2M8 was to have a cut-down rear fuselage and 'all around' view canopy.

Swallow nailed Number 3 with the Tachikawa SS-1 (more or less a Lockheed 14 with a pressurized fuselage).

 

[Nick Sumner]

The engine of the aircraft in drawing number 2 is intriguing - it looks almost as if it could be a radial with the supercharger in front of the engine like the configuration of the BMW 802?

 

[Wingknut]

Excellent posts, Justo, as ever.
However, I wonder about one of the designs in the first image in your Reply #105. I was under the impression that the lower of the two twin-fuselage designs shown was actually a fake. (The silver one – see: http://img399.imageshack.us/img399/6...insitei5tt.png.)
I hope I'm wrong, because it's a marvellous design, but see the 'WW2 in Colour' discussion-thread 'Lost Japanese twin-fuselage' at:
http://www.ww2incolor.com/forum/showthread.php?t=4101
As the thread above makes clear, the same image can be seen at a Japanese aviation site, which seems to specialise in 'What-if?' or fantasy designs (some of them quite bizarre): http://www.warbirds.jp/kakuki/kyosaku/sakuki14.html
(Wish I could be more helpful but I can't read Japanese …)
Cheers,

The Kugisho Tenga was certainly a bonafide design but I suspect the Japanese would have found out that you just couldn't swap out the radials for turbojets without some other modifications to the rest of the aircraft. Just look at the Tupolev Tu-12 as a comparison of what needed to be done to adapt the Tu-2 to turbojets.

As for the Ki-149, as far as I know, this designation has never been verified as belonging to the I-Go-1-C.

My dear lark,

for the Yokosuka Tenga it was a really project to japanese,see also;
http://en.wikipedia.org/wiki/List_of_World_War_II_jet_aircraft

some really projects;
Ki-128 was Tachikawa Ta-Go.
Ki-147 Mitsubishi rocket flying bomb.
Ki-148 Kawasaki rocket flying bomb.
Ki-149 Tokyo rocket experimental aircraft.

Hi,

when we discussed the Japanese projects pre-1945,we forgot many
projects in the period from 1920 to 1940.
For example,in 1934 for 10-Shi competition for two seat recce/observation
floatplane,the tenders were Aichi F1A1,Mitsubishi F1M1 and Kawanishi.
To Kawanishi,it supposed to be F1K1,and it was a project only,does anyone
know more info about it ?.

 

[blackkite]

Hi hesham enjoy!
http://www.geocities.co.jp/Bookend-Ohgai/3853/jnrs/jnrsC232a.htm
http://www.geocities.co.jp/Bookend-Ohgai/3853/jnrs/jnrsC232e.htm
Japanese text says, "IJN ordered Aichi,Mitsubishi and Kawanishi to develop modern observation(gunshot from battleship observation) floatplane in 1934.
This plane was planned to have high air combat performance to clear enemy fighters. Although F1A had better performance compared with F1M, F1M was selected by another reason(political?). Kawanishi did not perform actual design for F1K1."

 

[hesham]

Thank you very much my dear Blackkite,

and here is anther project,in 1927 and for interceptor fighter competition,
the tenders were; Kawasaki KDA-3,Mitsubishi 1MF2,Nakajima Type-91
and Ishikawa,the Ishikawa project was rejected in early stage,does
anyone know it ?.

 

[hesham]

Hi,

in 1928 and for Type-89 carrier attack bomber,the contenders were;
Mitsubishi 3MR3,3MR4 (B2M1 the winner) and 3MR5,Aichi,Nakajima and
Kawanishi.
In my source,all tenders submitted a proposals,does anyone know
them ?.

 

[blackkite]

Hi! You are absolutely right again.
In 1928(Showa 3,Kouki 2588),IJN ordered Mitsubishi, Nakajima, Aich and Kawanishi to design new carrier attack bomber which replaced 13-shiki carrier attack bomber. Mitsubishi ordered English engineer Smith(called 3MR3), Blackburn(called 3MR4) and Handley Page(called 3MR5) to design this aircraft and selected Blackburn design 3MR4, offered to IJN and accepted. Blackburn completed 3MR4 in England and arrived Japan in 1931.
Some modifications were applied to 3MR4 through flight test, employed by IJN as 87-type carrier attack bomber(Mitsubishi B2M1～2) in 1932. 204 planes were built.
Other company's designs were not described in my bible.

Oh! My dear hesham must be surprise to see this wonderful rare drawings.
Thanks for sharing us.

Nice pic, but would the red stripe have been added to the US insignia had WWII continued?

Sorry perfectly off topic, but please enjoy beautiful aviation art!

Thanks Ed!
I begin to post the abstract of "Super large bomber Fugaku(富嶽)'s engine(1)"
In the middle of 1942, after the lost of Midway battle, Chikuhei Nakajima(中島知久平), the founder of Nakajima Aircraft, planned grand idea which was to attack U.S. military manufacture to protect bombing to Japanese Archipelago.
According to this idea, he offered to IJA and IJN to develop and manufacture super large plane which surpass B-29.
At first, he decided to develop this aircraft by Nakajima Aircraft's private venture(called as Z plane) in January 1943,because IJA and IJN did not understand this big idea. ;D Also he persuaded IJA and IJN to realize this plane. Finally IJA and IJN agreed this plan in February 1944, selected him as s project manager and named this aircraft as Fugaku(old name of Mt.Fuji).
Fugaku's specification was as follows.
Wing span:65m, Overall length:45m, Wing area:350m2, MTOW:160ton, Engine power:30,000HP(5,000HP × 6), Max speed:680km/h, Range:16,000km with 20 ton bomb.
Fugaku's engine was Nakajima HA54(called as BZ in Nakajima) aircooling 4 array radial 36 cylinders(18 cylinders ×2), cylinder diameter:146mm, stroke:160mm, 96.4L, with 3 stage mechanical super charger, cowling outer diameter:1,550mm, Overall length:3,581mm, Dry weight:2,450kg,
5,000HP in take off(2,800rpm), 4,040HP in 6,300m(2,800rpm)
The chief engineer of HA54 was Kiyoshi Tanaka(田中清史),who had the carrier of Mamoru(護) engine chief engineer,the largest engine that Nakajima ever built.(double 14 cylinder air cooling engine).HA54 design team was consisted of 50 engineers.
There were many plan for Fugaku as project proceeded.
Attached drawing was Nakajima Z plane in spring 1943.

It look like it have been influenced bu Junker Ju 390

considering the nose of Junkers 390 , yes !
So if i remember very well, in history of Junkers 390, there was also interest of Japan for that type of plane !

 

[Pelzig]

Allied intelligence thought the Japanese were in possession of complete details for the Ju 290 in late 1943 but this has never been verified. What is known is that the Japanese obtained the license and plans for the Ju 390A-1 and the IJA was to collect the data from the Germans in February 1945. What is not known is if this transfer ever took place. As it was, the definitive bomber version of the Ju 390 (the V3) was never built.

Ed

Kawanishi Type 17 Experimental Ground Bomber (K-100) and Nakajima Ki-82 : anyone have more about this ?
???

 

[JFC Fuller]

To follow on from Red Lancer's question I would be curious to know if anybody has any details of the AEW version of the Ki-67?

 

[blackkite]

Hi Japanese airborne radar.H-6 and FD-2.
Tokai(東海,eastern sea) had the MAD(KMX).

Hi guys there is a lot written about western computing sight like those of the Mustang and German Askania designed
computing sight.Were the Japanese working on computing sights too?

Taiyo plan B : it's new for me !
By web, i have known the configuration named " Taiyo plan A"

 

[Stargazer]

First configuration of Senden is gorgeous, and incredibly reminiscent of Bell's Models 16 (XP-52), 19 and 20 (XP-59)!
