That's right my dear Blackkite.

Hi! YS-11 and YS-11-4 in each view are almost same scale.

Hi!
From Japanese wikipedia.
YS-11S (YS-11-4) was a short-take-off-and-landing type of YS-11.
This airplane carried four engines and the tail stabilizers were largely modified.
The range of this airplane was 900 km, and taking off and landing was possible for the runway of a 600-m class.
This airplane was planned in order to bid for the international competitive bidding(1970) of the STOL passenger plane used for the short distance city suburbs route of American Airlines.
The contents of a bid of international competitive bidding are as follows.
- The commuter airplane of 47 or more seats.
- No development costs.
- The purchase number of the aircraft were 20 to 300.
The makers which were chosen as the candidate were as follows
- NAMC (Nihon Aircraft Manufacturing Corporation)
-Hawker Siddeley
- Convair
-De Havilland Canada

Someone please show me the result of this competition and the shape of other candidates.

Hi YS-11J!(wiki pedia)

YS-11JYS-11のリージョナルジェット タイプ

• 全長29.5m、全幅32m、全高8.5m。

主翼の上にロールス・ロイス/スネクマ（SNECMA） M45Hターボファンエンジンを搭載、後退尾翼に改造し、最高高度7,620m（2万5千フィート）航続距離2,100km、巡航速度650km/hを目指した。設計図や当時の詳細パンフレットなども残っており、ジェット機は通常翼の下部分にエンジンがあるが、この機体のイラストではエンジンを翼上に搭載したタイプである。しかし、同時期にオランダ・西ドイツ・ベルギーが共同開発したVFW614も翼上にエンジンを搭載するタイプであったが、その奇抜なデザインは話題にはなったものの、市場には受け入れられず、わずか19機で生産中止に追い込まれた事に鑑みると、実現した場合、YS-11Jの販売が苦戦する事が予想できる。

Thanks blackkite!
The YS-11J resembles the VFW 614 not just with regards to position of the engines,
but even would have used the same engine type.

Hi Jens!
VFW 614 is far smart aircraft.

 

[Jemiba]

What strikes me, is the capacity of both designs. Whereas the YS-11 is credited with about 60 pax,
the VFW 614 had just a capacity of 40 !

 

[hesham]

Great find my dear Blackkite.

 

[Stargazer]

Great designs and images!

What hesham calls the YS-12 is called the YS-11S or YS-11-4 in all Japanese sources provided by blackkite.

Was that an alternate designation? And if so, do we have a source for it? Or is only a typo?

Hi Super YS(YS-11EA).
YS-11 with T64-IHI-10 engine.
Japanese airline pilots said that YS-11 was a under power aircraft.

Sorry YS-11-4 is simply my mistake. I mean YS-12-4.
But I can't find the name of YS-12 in Japanese sources. :-[
