The Harbour Tug

Posted Image



My entry of the "to sail the technic sea" contest is a floating vessel in the style of a Harbour tugboat. The feature of my tugboat is a Voith Schneider propulsion system. A classic propulsion system for ships works with a horizontal driveshaft and a propeller. The advantage of the vertical Voith Schneider propeller is, that it could adjust the boost of the propeller in all directions, without using a rudder.

The vessel can move sidewards and rotates in every radius which the captain wants. To get a little view on the maneuver abilitiys i made a short Video of my harbour tug  



Technical Datas
Two propellers in Voith Schneider style powered by twoPF-M motors with a gear ratio of 1:1.4
Two Pf-M to adjust the pitch of the propellers. The pitch controls the direction of boost.
Two receivers and transmitters
One 8878 LiPo accu
Dimensions
width:  280mm
length: 600mm
height: 360mm
weight: 2790grams

The Deckhouse and the Bridge is built modular to get a easy access to the electric parts

the two dishes are used to show the driver in which position the pitch of the propellers is.

on the afterdeck i have added a nonworking winch for the tow line

The stabilizer sword and two of the airtanks which are adjusting the waterline of the vessel.

Whan an awesome entry! It's functional, it looks the part and it's also incredibly cute - in a very Technic-y way, of course.
By the way, have you tested the "open water" RC reception range yet?
