PROPULSION ELECTRIQUE

Les bulles
autour de l'hélice : c'est de la cavitation ? :reflechi:

Spécifiques aux hélices BCD ? :jelaferme:

(désolé Jean, je n'ai pas pu résister) ! :oups: :mdr:

j'avais remarqué pour la bdc !
par contre l'instalation est une des plus simples que j'ai vu !

il y a une activation/embrayage a distance pour la BDC
The specially designed folding propeller, OZfoldProp, is developed and activated through the electronic ’gearbox’ OZecoCharge. This makes it possible to cruise and at the same time recharge batteries without the propeller folding back

Etonnant en effet :
j'ai relu : [i] Sailing and Charging procedures

When sailing and the batteries need charging the following procedures should be carried out:

1. The lever is put in ‘Normal’ position forward. The motor begins to turn and the propeller unfold.

2. The lever is now put in ‘Charge’ position. Now the propeller turns under water pressure and is held out by centrifugal force. If the speed of the boat is over 4 knots charging begins automatically. The motor is now a efficient generator that supplies power to batteries for use in the future or to ancillaries such as autopilot, lights or water maker. During charging the braking forces on the boat range between 0.05 – 0.5 knots depending on the circumstances. The propeller drag and charging performance can be adjusted. Charging is even possible in during tacking. At low speed the charging is disconnected automatically and when speed is regained the charging is smoothly engaged. Thus the performance of the boat is disturbed as little as possible.

3. When the maximum charge of 14.4 volts is achieved the charge rate is automatically regulated so that the batteries are not overcharged and the charging indicator begins to flash.

4. When full power forward or reverse is required during charging the gear lever is shifted to ‘High’ in either forward or reverse positions. And within one respectively four seconds full power is achieved! To return to charging simply place the lever in ‘Charge’ position again.

5. Charging is ended by shifting the lever into ‘Neutral’. The propeller is braked and falls back into the folded position.[/i]

Il ne s'agit donc pas d'une BDC ordinaire... on dirait la description d'une Maxprop pour laquelle cette procédure est en effet validée...

sans doute
qu'ils rechargent en marche arrière! :-D

merci Fred
c'est ce que j'appele, la sagesse collective de la liste ...

s'appuyant sur des positions individuelles solidement étayées !

Par ailleurs, ce n' est pas parce que je fais remonter l'info que je la valide c'est le contraire , c'est apres le debat qu'elle est validée ou non
