Circulation Control Technique on a Marine Propeller Duct |
|
|
|
Abstract |
|
|
|
A modified marine propeller duct that implements the circulation control technique is presented. The modification allows the conventional control planes to be removed from a marine vehicle such as an AUV whilst maintaining a suitable manoeuvring force. It is shown that for an AUV, a manoeuvring force improvement of over 600 % at 1 Knot is possible. The manoeuvring force at higher speed is at least equal to the original control surfaces. Efficiency is shown to be increased by 9.5 % for the same manoeuvring force. A non-ducted circulation control propeller is also proposed. |
