2) -Nihon Kagata Ku.II
from "Air pictorial"

Can someone help me, the question as follows:
known whether the experience of combat application (designing) Japanese WW2 gliders as (dive bomber / attack, fighter).? For example: BV-40-Germania.
I do not mean rocket / ram-jet powered Ohka, Baika.

Hi Guys

Great, thanks for the assistance. What were the Japanese designations for these German gliders?

Cheers
Gerhard
 
So far as my information goes, the Japanese did not make efforts to create a purpose built, unpowered glider along the lines of the German BV-40 or the late war German modifications of gliders to house MP-40 submachineguns for attack purposes.

Thank you Ed, for a qualified answer.
Of the projects, like the use of gliders I know:
-four projects in the Soviet Union, some in Germany, at least one in Italy, even one in the U.S. (designed by Lester P. Barlow)
A negative result in Japan, too, result))
 
In 'Japanese Special Attack Aircraft & Flying bombs' by Ryusuke Ishiguro
and Tadeus Januszewski ,mention is made of the Kokuyoku Jinryu.

It was a suicide glider with a 100kg charge located in the fuselage.
The plane should be launched with rocket assisted take off from tunnels
in mountain sides and used against ships and tanks attempting to land on
the beaches of the Japanese islands.
 
Hi Lark. That should be Kokukyoku Jinryu -- Kokukyoku being a family name. The same source also mentions a Kokukyoku Shusui-shiki Kayaku rocket for the IJN.

I think 'kokuyoku' means 'ruby'. Anyone know what 'jinryu' meant to a contemporary (it seems to mean 'people mover' in a light rail sense now).
 
To be technical, the Jinryu was a motor glider, not a true, unpowered glider. The use of rockets which were built into the glider to allow it to take off, by definition, removes it from being a pure sailplane. borovik's question was whether or not the Japanese had a purpose built attack glider like the German BV 40 which had no propulsion, which they did not. They also did not, so far as I know, adapt the sailplanes they had for attack purposes, such as the Germans did with the test arming of DFS Habicht sailplanes with 9mm MP40 submachineguns (which would have been of highly dubious value).

;D

In Ishiguro and Januszewski's book, "Jinryu" is defined as "Divine Dragon". There is also the Mizuno "Shinryu II", Shinryu also meaning "Divine Dragon". This may be the rocket glider/interceptor the authors reference as the MX75 in their Japanese Special Attack Aircraft & Flying Bombs book.

You are correct Apophenia,I indeed forgot a 'k' in the Kokukyoku..

Since the rockets of this design were only used for take off with
10sec. firing time , it was not a true powered glider I think.
During it's development,it was suggested that the plane should be
armed with rocketprojectiles for attacks against B-29's , which
should have made it an unpowered interceptor as the BV 40...
 
I'd imagine it may boil down to ones definition of a glider or what the intent of borovik's question was. A true glider has no means of propulsion at all. That is, it cannot take off on its own and requires some external means to get it off the ground, usually by being towed aloft. A motor glider has a means to take off on its own or sustain itself in flight if required.

True, the Jinryu was considered as a means to attack B-29s but I think the idea of the Jinryu being anti-bomber was passed along to the Mizuno Shinryu which was dedicated to the task rather than the Jinryu being adapted to such a task. The Shinryu was far more an aircraft like the Me 163 in mission profile which had a glider form given the short endurance of the rocket engines that required superior gliding capability in order to return to earth in one piece. The open cockpit Jinryu, if it was left as it was or modified to just include the added rocket motors and rocket armament, would have been hard pressed to take on B-29s at 30,000+ feet.

Hi Guys

I have found a new glider page. Could someone identify these?

1 appears to be an original design, developed/inspired by the Lippisch designed 'Pruefling' secondary glider, a following to the 'Zogling' primary.

2 appears similar to the Edmund Schnieder (Grunau) designed ESG 31 series, but differs somewhat from the drawing that I have.

3 looks very familiar, but I'm damned if I can remember what it is. The lobate ailerons are very distinctive, and the faired fuselage, along with the '22:1' data entry,
which is almost certainly the glide ratio, suggest the immediate post-war period.

4 is a Goppingen 1 'Wolf' from 1935. According to 'Sailplanes 1920-1945', Martin Simons, page 99, three were exported to Japan.

Sorry, that's the best I can do, perhaps one of our Japanese speaking colleagues can translate the page for us?


cheers,
Robin.
 
Hi! No.2 and No.3 were Tachikawa Ki24.
No.4 picture shows rear view and front view of KAYABA Ku3(HK3).
No.5 and No.7 were Fukuda Ki23.(Hikari-shiki 6.2)
No.9 was Kyushu imperial university Type5 "Mt.Aso".
No.10 was Kyushu imperial university Type7.
No.12 was Goeppingen 1.

No.1 was perhaps Nippon small aircraft "蝶 Chou:butterfly".
No.6 was Nippon small aircraft "Chikara(ちから:power)" nonlimited acrobatic glider for the IJN.
No.11 was Maeda type 6.
Now we can identify all of the gliders here.

...as the Germans did with the test arming of DFS Habicht sailplanes with 9mm MP40 submachineguns (which would have been of highly dubious value).


Drifting OT briefly, but IIRC, the MG armed Habichts had clipped wings (Stummel Habicht), and weren't intended for operational use, but for gunnery training by trainee Me163 pilots.

Hi! I found this great website for Japanese gliders.
unfortunately it's written only in Japanese, I will try to explain you one by one.
If you click left side of this website,you can see many Japanese glider pictures and 3-side views. 

http://www.vsha.jp/page219.php
 
Hi!
Kyutei 1 gata.(Sato Maeda 1-go)
Kyutei 2 gata.(Sato Maeda 2-go)
Kyutei 9 gata-A.

Kyutei means Kyushu teikoku daigaku(九州帝国大学)(the Kyushu imperial university,now Kyushu university.)

http://www.kyushu-u.ac.jp/english/university/history/index.php

Gata(型) means "type".
Go(号) means "number".(1-go means No.1)
Sato(佐藤) and Maeda(前田) are designer's name.

Brilliant! Now it may be easier to distinguish between the various gliders we find on old Japanese photographs. These two models also remind me of the Tachikawa Ki-24, don't you think so?
 
Yes I think so.
Next one is Mizuno(美津濃) shiki 102 gata.
Shiki(式) means "type",too
Mizuno is the maker of this glider.

And Maeda shiki 105 gata.

Can you tell me why the L7P1 prototype seems to have two fuselages glued together? Doesn't make sense to me.

Hi guys

I have always been under the impression that Chikara was also known as the MXJ-1.
Is this correct?

Cheers

I don't think so. According to my research, MXJ1 was Nihon Kogata's Model K-15, submitted to the 17-Shi Experimental Research Plane specification. This Special Trainer Glider was known as the Wakakusa. Its competitor in the same 1942 competition was Mizuno's MXZ1.
