I haven’t seen anything on the Ki-162.
The rest I’m aware of, though the jet-powered P1Y1 would be quite bad I think. Would be slow for a jet and with poor acceleration. J7W2 stands out since it would have better performance than the J7W1 from 400kph onwards (above this speed Ne-130 would produce more thrust than existing radial), which is exactly where the J7W airframe wants to be.
Basically He 162 but with japanese army weapons.
Cool I guess. I don’t really want a straight copy with only weapons changed.
The engine is probably worse.
In WoA it has 30mm Ho-155
There is book about all secret projects: Japanese Secret Projects: Experimental aircraft of the IJA and IJN 1939-1945
Tachikawa 162 isn’t really real tho
Is this for the whole GCAP project or just the Japanese version
I am not fully sure as i said in the next reply if the GCAP fighters will differ between nations is unknown currently. At least for now we can assume this will be for Japan
Ki-116 would be interesting, less power but IIRC they also managed to cut down weight.
Of those only the nitrous oxide injection and R models could be added unfortunately. Though a Ha-44 Ki-84 would be really good, it’s the engine we have right now in the Ki-83.
Well same with R2Y2
Japan had plans to convert the R2Y1 into a jet aircraft. That has some historical basis. AFAIK, Japan never had plans to use the He 162 at all
Ki-83 used a Ha-43, though I keep forgetting which variant exactly.
The four Japanese 18-cylinder radials and their variants are very easy to mix. Here are some basics to help with that.
Mitsubishi Ha-42 - The largest one of these. Only ever planned for bombers.
-Ki-67 (Not really named Ha-42, but it’s direct predecessor.)
Mitsubishi Ha-43 - 2nd smallest
-Ki-83, J7W1, A7M2
Nakajima Ha-44 - 2nd largest
-Ki-87, Ki-94-II, J6K (other planned variants)
Nakajima Ha-45 Homare - The smallest and only one which really went into service.
-Ki-84, N1K1-J, B7A, P1Y1, A7M1, J5N1, J6K1
Well say why there is information plans about making Ki-162
From: Tachikawa "Ki-162": a real project? | Secret Projects Forum
From the mentioned “Japanese Secret Projects” by Edwin M. Dyer III :
" …nor the Japanese version of the He 162 would progress past the initial design stage. Only the Nakajima Ki-201 ever made it to the construction phase which, by the end of the war, amounted to a single incomplete fuselage.
As a note, ‘Ki-162’ has been used by some as the designation for the Japanese produced He 162.
There is no historical evidence to sup-port this although it is not without precedent, such as the case with the proposed Mitsubishi Ki-90 that was to be the Japanese version of the Junkers Ju 90."
It could also be confusion with similar designs such as the Baika.
I find the later Japanese 18-cylinder radials extremely interesting. For most of the war, Japanese engines lagged somewhat behind other nations, but they managed to really supercharge their efforts (pun intended) and produce the Ha-43 and Homare. The Homare is very impressive given how much power its later models produced within such a small frame. The Ha-43 is probably my favorite Japanese engine, but the Ha-42 is cool too. I believe it was to be used on the Ki-91 as well.
I believe there was a 3000 hp radial planned as well
3100hp radial would be the 22-cylinder Mitsubishi Ha-50. It had 2 rows of 11 cylinders, which made the diameter much larger. At least one document lists it for Ki-91.
Other over 3000hp engines include 3400hp Aichi Ha-70. Rather well known 24-cylinder twinned V-engine for R2Y1.
There was also the 5000hp 36-cylinder 4-row Nakajima Ha-54 for gigantic bombers. Quite a long documentation of this engine has survived.
What a curious find, even though all those with 2x 13.2mm on cowling might have been field modifications. Too bad there are no photos of these.
It is finally happening
