Hi,

I know the Ki series from J-aircraft site,but the little known
is the engines and the number of seat to each project.

Ki-13 & Ki-14 were single engined two seat Army Co-operation projects.
Ki-22 was twin engined multi seat heavy bomber project.
The Ki-29 & Ki-31 were single engined two sdeat light bomber projects.
The Ki-40 was two or three engined experimental command recce project developed from Ki-39.
The Ki-41 twin engined light transport project.
The Ki-47 twin engined four seat light or medium bomber project.
The Ki-50 was twin engined multi-seat heavy bomber.
The Ki-90 was twin engined multi seat medium bomber.
The Ki-92 was twin engined 39 passenger transport project.
The Ki-95 was twin engined two seat recce/fighter project.The Ki-101 was twin engined heavy fighter.
The Ki-112 was twin engined four seat heavy escort fighter project developed from Ki-67 bomber.
The Nakajima Ki-117 was a single seat fighter project, given the company designation Ki-84N.
The Ki-128 was Tachikawa Ta-Go.
The Ki-147 Mitsubishi rocket flying bomb.
The Ki-148 Kawasaki rocket flying bomb.
The Ki-149 Tokyo rocket experimental aircraft.
and Kawasaki Ki-174 was a single seat special attack version of the Ki-48 twin engined aircraft.

OK my dear Blackkite.
Please do not expect too much. ;D

Ki-118 was short-distance fighter plane which was due to be ordered from Mitsubishi from the Japanese army in 1945.
It has only become clear that a engine was Ha 211 (Ha 43, MK9).
However, those details are not clear, although Mitsubishi does not have the remaining power of the members of a design which can make a new fighter as an experiment at this time and キ 118 is presumed to be appropriation of the existing plan.
It might think temporally and may have been the army version of Reppu-kai.

The duty of Ki-112 was the attack to an enemy airfield institution, a terrestrial airplane, an important place, and an enemy vessel.
It seems that Mitsubishi had started basic research in 1944 in the early summer although it was not clear in trial production directions of Ki-112 whether it was taken out at which time.
At the beginning, as an engine of Ki-112, Mitsubishi HA214(HA42)Vulkan coupling drive 2 stage supercharged engine was selected, and the design was advanced.
Changing the engine of Ki-112 into a Ha 214 turbocharged engine from Ministry of Supply to Mitsubishi in October, 1944 was directed.
Change of an engine was difficult, and when Mitsubishi wanted to advance a design with the engine of a schedule at the beginning, it offered it to Ministry of Supply.
The trial production work of Ki-112 stagnated and was stopped at this time after all.

In summer 1943, the IJA ordered Nakajima to develop night fighter based on the IJN’s Gekko.
Ki-101 was a twin engine night fighter. The engine was HA-219, which was one of the most powerful engine in Japan at the day.
The armaments were forward direction one ~ two 30 ~ 40 mm cannons, and two 20mm cannons.
And revolution type 20mm cannons-equipped-at-a-battery type.
Maximum speed was 700km/h at altitude 10000m.
No.1 prototype was planned to complete in March 1945, but actual production never started.
 
I only treat these unbuilt projects and you moved to designation system. Is it right???? Please think about it again carefully.
 
I agree with blackkite somehow. The idea was not to provide a comprehensive Ki- list, but to list those that had not been built so they could be discussed in a separate topic. There is already a very long "Early Japanese projects" topic, and I think there mustn't be two of them! But moving this list here was a little useless I think.
Perhaps a valuable split could be to have a topic for IJA projects/prototypes and another one for IJN projects/prototypes?
Another alternative could be to have a topic for prototypes and another one for paper projects only, as was the initial idea here?
 
Excellent my dear Blackkite,


if there any drawings to them,that will be great.
 
The list isn't complete, in most cases no list was complete from the start. In the Early Projects section
the result would be another thread dealing with a lot of projects of different manufacturers, hard to
handle from the start. The RLM designations, for example were dealt with, too, in the designations section.
Why not take this great list as a starting point for working it off with specific threads in the Early Projects section ?
Although incomplete (something, that maybe can be cured) it's more appropriate here, I think Official designations
in the designations section, specific projects in the Early Projects section.
That we still have a thread, where we neglected this principle and are suffering now occasionally from problems
to locate a special type or photo in nearly 300 posts should be a stimulus, not to repeat this, not a reason to lay
the seed for another one.
And of course, it doesn't absolve the moderators from the responsibility to clean this thread up in a suitable way,
but thats's a different story. :-\
 
Well, the goal was never to provide a complete Ki- list or even attempt to build one, but to list a series of obscure designations that could be discussed.

I agree though that discussing a list when there are no images to post is perfectly compatible with the Designations section.

The risk however, is that this topic find itself crowded with lots of stuff that has nothing to do with discussion the designations at all!

We have lots of cases here, where types, we only have short descriptions of, are dealt with in the designations section.
Or where actually built types are shown with single pictures here, just to make clear, what is meant. That's ok, I think.
And if stuff beyond the scope of designations is posted here, it'll simply be split and moved to a dedicated topic.
And probably there will still be topics merging projects of different manufacturers, for example something like
"C6N Saiun Contenders", IF there is only small information about those competing designs available. But someone
asking "Was only the Saiun proposed" would find an answer relatively quickly then, I think, without browsing a dozen
pages or more.
We'll certainly still have to split and merge a lot in the future, and probably many of us will still moan a lot about
information, pictures or drawings, that could only be recovered after a long search. But everybody can help to minimise
such work by creating more specific topics. it's a learning process for us all. ;)
 
In my humble opinion,both Jens and Stéphane have a point.

Working from a single Ki projects list , who can be expanded, avoid mixing up all kind of info.
Just take one Ki number and contribute all the info that can be found to create a new topic about that single subject.

The same can be done for the Japanese Navy aircraft paperprojects as Stéphane suggests.

This method can save us from a new labyrinth were no one can find the info he's looking for.
 
There is no intention that I continue a useless argument boundlessly.
When it is not thought that it is very unsuitable, I think that a contributor's intention should be respected as much as possible.
 
I just noticed this thread, now I have a complete list of Ki designations from Ki-1 to Ki-119 except for Ki-26(?), which I know nothing about.


From Ki-119 to Ki-230 is quite empty, the ones that I have noted and can be found in threads here are:


Ki-128


Ki-147


Ki-167


Ki-174


Ki-200
Ki-201
Ki-202


Ki-230


Can anyone fill in the spaces? ;D
 
The Ki-26 (just like the Ki-24 and Ki-25) was a Tachikawa (Ichikawajima) glider.

Additions I can provide (no sources though):
  • Ki-120: Experimental Transport (no manufacturer known)
  • Ki-148: Experimental Unmanned Missile (Kawasaki)
  • Ki-149: unknown type (Tokyo)

Ki-104 : Experimental fighter, Kogiken(Aeronautical Research Institute), only planned, Tachikawa Ki-94-Ⅰbase.
Ki-103 : Experimental fighter bomber, Mitsubishi, only planned, Mitsubishi Ki-83 base.
Ki-101 : Experimental night fighter, Nakajima, only planned
 
Thank you Skyblazer, the Ki-162 should also be added to the list.
 
Hi,


Ki-149 was Tokyo rocket-powered experimental aircraft project.
 
I can't find any information about Ki-149.
Ki-148 I-GO type-1 kou missile(radio guided bomb(Mitsubishi)), Number of production : 10
Ki-148 I-GO type-1 otsu missile(radio guided bomb(Kawasaki)), Number of production : 180
 
Ki-99 : Experimental interceptor, Mitsubishi, only planned
In 5/7/1943, the IJA ordered Mitsubishi to develop short range fighter which had HA-211 engine.(Mitsubishi MK9A engine). Ki-99 was a single engine single seat fighter with 30mm×2 cannons and 20mm×2 cannons. Ki-99 was the IJA and the IJN joint program, terminated in 5/1944.

Ki-90 : Experimental short range bomber, Mitsubishi, only planned
In 9/7/1943, the IJA ordered Mitsubishi to develop short range bomber which have dive bombing ability. Ki-90 was planned to be a succeeding plane of Hiryu bomber. Ki-90’s base was Junkers Ju-88. Ki-90 had 4 seats in nose part, had two turbo charged HA-214lu engine(Mitsubishi HA-42, MK10 engine), terminated in 5/1945.

Ki-89 : Experimental research aircraft, Kawasaki, only planned
Ancestor of Kawasaki KI-119 fighter bomber.

Ki-82 : Experimental high speed heavy bomber, Nakajima, only planned
No.1 plan : HA-45 engine. Maximum speed 580km/h.
No.2 plan : Liquid cooling experimental HA-39 engine with skin cooler.
Maximum speed without skin cooler 610-620km/h, with skin cooler : 650-670km/h.
Ki-82 was terminated because of Ki-67 success.(Ki-67 with Ha214 was planned to have maximum speed 630-640km/h.)

Ki-81 : Experimental airplane with heavy armaments for commander boarding.(Leading aircraft for light bombers formation.), Kawasaki 99-shiki twin engine light bomber base.

Ki-75 was a twin seat long distance fighter plane of which it conceived for covering of a bomber.
This concept was stopped around 1943, not taking shape.
Changing the maker of Ki-75 into Mitsubishi was also taken into consideration.

Ki-73 : Experimental high speed reconnaissance aircraft with 2600hp HA203 engine, Mitsubishi, only planned

Ki-72 : Experimental close support/reconnaissance aircraft, Tachikawa, only planned

Ki-69 : Experimental escort fighter, Mitsubishi, only planned, Ki-67 base.
 
To clarify, the Mistubishi Ki-90 was to be the Japanese bomber version of the Junkers Ju 90 which was derived from the Ju 89. In fact, the IJA assigned the kitai number 90 to the project even before they got the technical information for the Ju 90, confident Junkers would deliver. Well, Junkers didn't and the entire Ki-90 project was canceled.

During WW2, the Japanese were not very successful in obtaining German bomber designs to make their own. Notable failures in trying were the He 177, Ha 142, Hs 130, Fw 200, and the Ju 390.

The only real success was pre-WW2, examples being the Ki-1 (derived from the Junkers K 37 bomber) and the Ki-20 (derived from the Junkers G 38).

Just retraced the page I'd saved from a Polish website. Here is what it had to say:

Mitsubishi Ki-147 - jednosilnikowa rakietowa bomba latająca (pocisk skrzydlaty klasy powietrze-ziemia/woda). Zbudowano 11 egzemplarzy (znanych także pod oznaczeniem Igo-1 Ko).
Kawasaki Ki-148 - jednosilnikowa rakietowa bomba latająca (pocisk skrzydlaty klasy powietrze-ziemia/woda). Zbudowano 180 egzemplarzy (znanych także pod oznaczeniem Igo-1 Otsu).
Tokyo Ki-149 - jednosilnikowy rakietowy pocisk skrzydlaty klasy powietrze-ziemia/woda. Zbudowano ? egzemplarzy (znanych także pod oznaczeniem Igo-1 Hei).

I do not understand Polish, but the Google Translator says: "Winged missile. Also known under the designation Igo-1 Hei. Built?"
 
Another file I'd saved, also in Polish, was a Kitai list by a certain Bogdan Amatan. In it, he referenced the Ki-149 and gave his source as follows:

T. Januszewski : Lotnicy Śmierci i Ich Samoloty, s. 229

I'm attaching said file for reference.

Great stuff, y'all, but I'm getting confused because there's a topic in the Designations section dealing specifically with Ki- (Kitai) numbers and I believe all this talk and lists really belong there. It's hard to keep track of additions where they are made in both threads!
 
Hi Sky! I only treat unbuild Ki- series project in this topic. Of course I must take care designation system. ;)
 
That's the site,which has some mystery aircraft,


I spoke about it before,and many projects for other country still there.

Discussing designations (whether built or unbuilt) belongs in the Designations section, especially if there are no images to share.

Discussing specific types in detail, whether built or unbuilt, especially if there are pictures to provide, belongs in the Early Projects section... simple as that!
 
Ok, those posts from the "Japanese Projetcs before 1945" thread, that are great for
completing the Ki-list are added here.
And the post about the I-GO missiles an now be found here
http://www.secretprojects.co.uk/forum/index.php?topic=22285.msg224519#msg224519,
hopefully as a seed for a lively thread about japanese air-to-ground missiles, analogue to the
thread about Japanese ground-to-air/air-to-air missiles in WW II there.
