Japanese Gliders and Assault Gliders

[blackkite]

Unfortunetely I can't find any information about Kyutei-4,-6 and 10 in Japanese sources.

 

[blackkite]

Hi! Kyutei type-5.

 

[Maveric]

Thx my dear blackkite.

 

[blackkite]

Hi! Kyutei type-12.（Please confirm #159,too)

https://www.secretprojects.co.uk/threads/japanese-gliders-and-assault-gliders.4357/post-371974

This soarer was not completed because Japan was defeated in the Pacific War at the stage when the skeleton was completed.
This soarer was the last glider planned by Kyushu Imperial University.

 

[blackkite]

Kyurei type-8 was a second glider of type-2 primary glider.

The Tondokoro type 1 hang glider is the first domestically produced hang glider to fly in Japan.
It was produced in 1937 (Showa 12) by Yoshikatsu Tondokoro.
The Tondokoro type 1 succeeded in the first flight in Entoku-village, Shimotakai- country　Nagano-prefecture on March 10, 1937, by Yoshikatsu Tondokor.
Then, about 4 test gliding was performed.
After that, YoshikatsuTondokoro entrusted the Tondokoro type 1 glider to his alma mater, the former Suzaka Junior High School, and after working for Tachikawa Airplane, became an inspector at the Aviation Bureau of the Aviation Bureau, but the flight by the Tondokoro type 1 glider continued.
On February 11, 1943 (Showa 18), after moving the storage location from Susaka Junior High School to the hangar of the Kirigamine Glider Study Group (Kirigamine), Tondokoro type 1 made flight experiment on snow was conducted at Kirigamine.
However, in response to the flight suspension order issued by the Supreme Commander for the Allied Powers (GHQ) following the end of the Pacific War in 1945 (Showa 20), the Tondokoro type 1 glider owned by Kirigamine Glider Study Group was incinerated with other gliders.

Hi!
One of the flight record of Tondokoro type 1 hang glider(Authorized glider number B-119) : Flight height 30m, Flight distance : 150m
Yoshikatsu Tondokoro（頓所好勝） was a amature designer/constructor,and later lived in Hiroshima.
In 1943, he sometimes used ski when takeoff at Kirigamine ski gerende in Nagano prefecture.

Katsuyoshi Tondokoro designed Shinryu when he was a Ministry of Communications Aviation Testing Laboratory staff.

Hi,

what was this ?.

The Xplanes of Imperial Japanese Army & Navy 1924-1945

A few years ago a friend sent me these pictures, since then I keep them on my laptop in the Japanese aircraft folder, however he doesn't remember the website where he downloaded them , so I can only share them on the forum for everyone to enjoy.

 

[blackkite]

Thanks a lot. Excellent pictures.
Mr.Tondokoro's collegue test pilot Mr.Narabayashi offered a power up glider plan based on this Shinryu.
Mr.Narabayashi's plan had 30 seconds burn time six rockets, 750km/h maximum speed.
The IJN also planned Shinryu2 with 36 seconds burn time rocket engine which the IJN already developped..

”After the test flight of Shinryu (Shinryu Type 1), a development plan for " Shinryu Type 2 " with　fighter-bomber specifications was started with the aim of extending the cruising range using a rocket with a burning time of 32 seconds. , It ends without being realized. Type 2 was developed as a combat attack aircraft with delta wings and canard, with a cruising time of about 120 seconds, which is about the same as the Ba 349 developed by the Luftwaffe at the same time by reloading the solid rocket booster. The armament was planned to be equipped with rockets for attack.”

[blackkite]

Hi!
Climb to altitude 200m using both side two rockets①, then ignite middle rocket② to increase speed for special attack.
Rocket thrust : 133kg each, burn time 10seconds. Bomb : 100kg.
1000 pilots were trained for this glider by Wakakusa and Hikari glider until the end of the war.

I noticed there is a Kaiten in the background, so after a Google search I found the site (some other pictures at the link):

Hi all,

found this pics from japanese gliders of the WW2. Can you give a identification?

Good day,
I am currently writing a book on WWII glider operations worldwide. I have a lot od informations about german, American and British gliders, but Japaneses and Soviets gliders informations are very difficult to find, looking forward any help to finish that book. Documents and pictures will be welcome. Thank you very much, I am Francois Gauthron email francois.gauthron@wanadoo.fr

 

[hesham]

Good news,and welcome aboard Normandy,

[ArmchairSamurai]

Found this in a weekly intelligence report from 1945, forget what month. Can provide the link if anyone is interested, but all the information about this glider is on the pages I uploaded. Frankly, this "raider glider" is probably nothing more than a made-up story a POW relayed to US interrogators at the war's end, but who knows... Thoughts?

 

[Mavrick5]

Interesting. I wonder if this glider actually existed. However, it is not at all impossible given the state of Japan in 1945 as they were preparing for Allied invasion

 

[Tadeusz Januszewski]

Please send me link about unknow Japanese glider/

Does anyone have information on Ku-12 ( and Ku-17 gliders. check this link.

Could someone please identify these gliders.

Could someone please identify these gliders.

Not sure about the 3-view drawing (although it suggests Kyutei to me).

Your nihon-hati-gurabia4.jpg image shows motor-glider J-BBEA, a 1941 production of the Nippon Kogata Hikoki K.K. (Japan Small Aeroplane Co. Ltd.; also given as 'Nihon Kogata'). The c/n is given as 'Nippon 1'. [1] Power was provided by a 25 hp Nihon Nainenki K.K. HA-90 4-cylinder engine. [2]
______________________________________________

[1] I don't know what that signifies (Nippon Kogata had been around since 1937 and produced the Chou and Chikara gliders and at least two Otori sailplanes.

[2] This HO4 was a licensed-built Japanese version of the French AVA Type 4A-00 engine. Nihon Nainenki K.K. was based at Furuichi-machi, between Nagano and Tokyo.

From, Japanese Experimental Transport Aircraft of the Pacific War,

Nippon Kokuki Kogyo D-1 was a low-wing research assault glider,may a project ?.

The problem is that,they drew it with two engines mounted on the wings ?!.

 

[Mavrick5]

I have no idea, Hesham. Do you have a picture?

Yes I have the book itself Mavrick,but it is still available,so I can't send it;

[Mavrick5]

Oh, Ok I actually have this book.

I was always under the impression that a glider was build with to proof the concept.

 

[Apophenia]

... I was always under the impression that a glider was build with to proof the concept.

I believe this is conflating two different projects related to the Ki.54.

Your image shows the 'twin-nacelled' glider built in 1939-40 to proof Tachikawa's Y.39 concept (which becomes the Ki.54). The D-1 mentioned by hesham was a later, engineless Ki.54 derivative test-flown in June 1943.

 

[kocovgoce]

my question is, were the gliders supposed to be towed all the time across the pacific ocean to the designated island or were they just towed to a certain height and then released to use warm air columns?

 

[riggerrob]

my question is, were the gliders supposed to be towed all the time across the pacific ocean to the designated island or were they just towed to a certain height and then released to use warm air columns?

Few warm air currents over the middle of an ocean. Also consider that few assault gliders have flat enough lift-to-drag ratios to cover significant distances after release from tow planes.

 

[Mavrick5]

Halo everyone. Could anyone perhaps identify this glider? I could not find the name in the website below.

Explanation of this picture says that
Second work, Shogakukan-go, completed in September 10, in 1955
January 1956: New Japanese record for flight time set

今日の一枚

Kofu Technical High School Ibaraki Prefecture Alumni Association Chairman Hirotoshi Murakami

Shogakukan go
Did you know, juniors? Kofu Technical High School had a traditional glider club. After school, on the grounds, the members were flying the gliders by pulling a thick rubber rope. They only stayed in the air for 2-3 seconds, but I was fascinated by the members' complete concentration. I wanted to try flying it once.

 

[blackkite]

This glider is Sumi type JW-1 model (JA0119). (鷲見式JW-1型)
Her name is Shokakukan-go. (小学館号)

On January 13, 1957, Shimizu Rokunosuke of the New Japan Glider Research Society flew a JW-1 two-seater Soarer with a passenger for about four hours, taking advantage of the updraft on the slope of a 100m-high mountain known as "Gurayama" near the Tateyama Maritime Self-Defense Force Airfield, breaking the endurance record set by Kawabe in 1952 with the SM-206 secondary glider. This JW-1 glider was designed by Sumi Joji and built by Kofu Technical High School in 1955.

Great stuff, thank you for your assistance Blackkite
