The temporary assembling of the engine.

The temporary assembling of the engine.
The engine is “Isotta Fraschini Cantilever” similar to it which was used for Piaggio Pegna P.C.7.
The big difference is a shape of the oil pans, and it is connected to a frame directly.

エンジンの仮組。
エンジンはPiaggio Pegna P.C.7に使用されたエンジンと酷似した『Isotta Fraschini Cantilever』です。
大きな違いはオイルパンの形状で、それはフレームにダイレクトに接続されます。

Consideration of Savoia Marchetti S.65

2015_1215

I do not have a structure drawing.
Therefore I suppose most from a photograph.
Three pipes supporting the engine of “the cantilever” penetrate the body.
A float prop connects with the pipe.
The structure to support a tension line supporting a wing is necessary.
It is thought that they combined a pipe with a partition without waste.
An engine partition sandwiches the cockpit.

I temporarily assembled them.

Completion

It finally was completed.

Memo
* As for the engine, Isotta Fraschini, Asso is special.
It resembles an engine “cantilever” used for Savoia S.65.
* A wing and the front hydrofoil are right and left asymmetry
(these support torque)
* The hull has an opening and shutting-type air in take in the side. (I confirm a window two type and a window three type)
* A clutch sandwiches front and back of the engine (for air propeller use and the water screw)
[important] Pilot needs three arms to change this at the time of a takeoff.
* The exhaust pipe confirms a long type and a short type. I choice long type (an improved model?).
* The biggest mystery. I do not know where is the sensor (Pitot tube) of the air speed instrument in. (is this because it was abandoned before completion?)
* The clutch assumes a spring expression.
* Thanks for cooperation of Mr. Giambattista.

メモ
*エンジンはイソッタ・フラスキーニ・アッソ改。サヴォイアS.65に使用されたエンジンと同時期に開発された「カンチレバー」に酷似しています。
*翼は左右非対称
*前部水中翼は左右非対称
*開閉式のエアインテークと思われる窓を持つ(窓2つタイプと、窓3つタイプを確認)
*エンジンの前後をクラッチが挟む(プロペラ用とスクリュー用)
離陸時にこれを切り替えるため、パイロットは腕が三本必要。
*エクゾーストは長いタイプと短いタイプを確認。今回は長いタイプ(改良型?)を選択。
*最大の謎。エアスピード計器のセンサー(ピトー管)がどこにつくのか分からない。(完成前に放棄されたからか?)
*クラッチはスプリング式を想定。
*Giambattista氏の協力に感謝。

One end.
The thing to be able to make with knowledge as of now was completed.
I thank for the cooperation of many friends and pioneer.

いったんの完成。
現在の知識でできることはしました。
新しい資料が見つかれば改訂していくつもりです。

Finally ready for final rendering is now ready. 10000 × 10000-pixel rendering takes about 10 hours. I must wait for the weekend without work.
いよいよ最終レンダリング。1万ピクセル×1万ピクセルのレンダリングに約10時間かかります。
仕事のない週末を待たねばなりません。
