1. ODU

の取付位置について

1. ODU installing position

ODU

を船のセンターにまっすぐ取付けます。

・アンチベンチレーションプレートがセンター

からずれていたり、傾いていたりするとキャ
ビテーション(空洞現象)を起こしやすく、
スプレー(飛沫)もあがりやすくなります。

Mount the ODU straight in the center of the hull

If the anti-ventilation plate is off center or tilted, 
it may cause cavitations and raise a spray of 
water.

実際に取付ける前に目的に応じて

ODU

の取付け高さを設定します。

取付け高さが高い

 通常

H = 0

10 mm 

 ODU

が水中に沈む量が少なくなる

・メリット

スピードがアップします。(注)船底等の形状により変化します。

・デメリット

キャビテーションやベンチレーション(空転現象)が発生しやすくなります。
特にラダーを切った場合に多く発生します。

取付け高さが低い

 通常

H = 10

20 mm 

 ODU

が水中に沈む量が多くなる

・メリット

低速時にラダーを切った場合でも、キャビテーションやベンチレーションが発生しにくく
なります。

・デメリット

スピードがダウンします。

キャビテーション

… プロペラの圧力の低い部分が気化し、気泡が発生し、非常に短時間でつぶれること。 

(空洞現象)

 

推進力がダウンします。 

ベンチレーション

… プロペラの回転により、水面から空気が入り込み、プロペラが空回りすること。 

(空転現象)

 

推進力がダウンします。 

 

特にラダーを切った場合に多く発生します。 

Before actually installing the ODU, adjust the height at which the ODU is installed in 
accordance with the purpose.

The ODU position is too high

Normally H = 0-10mm 

 The ODU is not sufficiently submerged in water.

* Advantage

The boat will speed up. Note) The speed will change depending on the shape of the bottom of the boat.

* Disadvantage Cavitations and ventilation easily generate especially when the rudder is moved.

The ODU position is too low

 

Normally H = 10-20mm 

 The ODU is too submerged in water.

* Advantage

Even when the rudder is moved at low speed, there will be few cavitations and ventilation.

* Disadvantage

The speed will slow down.

Cavitations:

The part of the propeller with low pressure creates 
air, and bubbles, which are destroyed very quickly, 
are formed. The forward force is reduced. 

Ventilation:

Due to the rotation of the propeller, air is drawn in 
from the water surface, and the propeller rotates in 
air. The forward force is reduced. 
This occurs a lot when the rudder is moved.
