Talk:Kayaba Heliplane

There is a lot in the article, as first written, that is patnently untrue and/or unverifiable.
Please let us stick to verifiable facts (not very many!!)--Petebutt (talk) 08:06, 11 February 2017 (UTC)

Kayaba Heliplane

Kayaba Heliplane Type 01 : The photograph taken by 1954 in Japan. Issued by: public relations section　of the corporate planning department, KYB Corporation (Kayaba Industry). ＫＹＢ株式会社 経営企画本部　広報部

Please ask the specifications about Kayaba Heliplane Type 01 by Japanses Language （日本語）　only！

At least two points, KYB has spec data. Powerplant: 1 × Continental IO-360-AF air-cooled 6-cylinder horizontally-opposed piston engine 180 hp (134 kW )

Propellers: 2-bladed wooden fixed pitch propeller

The picture posted on Wikipedia Commons is in the state of wooden 2 blade fixed pitch propeller like the prototype Cessna 170 B. After photographing this picture in 1954, it was replaced with a 3-blade variable pitch propeller.

"''':OK
 * 1) Have included the ref for the specs
 * 2) Powerplant completely wrong as the IO-360 did not exist untiln the late 1960s!!
 * 3) The propeller shown is the fixed pitch. No evidence, as yet, that the variable-pitch prop was ever fitted. As now in the text--Petebutt (talk) 08:52, 11 February 2017 (UTC)"


 * I approve that point.

Lycoming O-360
Okay I think the Japanese Wikipedia misunderstood about Lycoming O-360 ??

It's probable that the engine was a Continental C145-2 air-cooled flat-six, since that's what was in the Cessna 170B (Jane's AWA, 1955-6). Not usable, though, as it's only an informed guess.TSRL (talk) 17:20, 11 February 2017 (UTC) The Flight article, now a ref, confirms that the fuselage was that of a 170B and that it retained the original engine. A slight worry is that the 170B had the C145 (O-300) engine, which, as it says on the tin, only produced 145 hp. The geared GO-300, at 175 hp, would fit Flight's description but was not fitted to 170Bs so I've not specified type beyond Continental.TSRL (talk) 19:16, 11 February 2017 (UTC)


 * Poked about a bit further: the E185 is a close match to Flight's 180 hp. The E185 was later included in the O-470 series and was around before the Heliplane; it is mentioned in Jane's 56-57 which gives no specific date but says the E series started in the 1940s. The Wiki article gives first certification of the O-470 series as 1950. So the E185 is also a plausible answer, though not Flight's "original 180 hp Continental engine"; we still lack a reliable source to avoid NOR.TSRL (talk) 22:26, 11 February 2017 (UTC)

The caption to the piece (2 images) in Japanese It is unknown like [ whose two photographs of these were ] a poster for whether it was a catalog of the Heliplane concept. So to speak They are details of the dream which President Shiro Kayaba looked at. There was a possibility of enough of succeeding if even funds continue. I am the airplane of the concept accepted by the present age, and the similar development project was furthered actually in the United States. The field of Japan's original aviation might be developed while adding computer technologies if this really flew.

この２つの写真がヘリプレーン構想のカタログであったのか、ポスターのようなものであったのかは不明だが、こんな写真が残されていた. いわば萱場社長が見た夢の細目である. 資金さえ続けば成功する可能性は十分にあった. 現代にも通用するコンセプトの航空機であり、現にアメリカでは似たような開発計画が進められていた. もし、これが実際に飛んでいたとしたら、コンピューター技術などを付加しつつ、日本独自の航空分野が開拓されていたかもしれない. --Yuiyuasa (talk) 13:04, 13 February 2017 (UTC)
