efferman Posted March 14, 2012 Posted March 14, 2012 The Harbour Tug 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. more pictures on flickr and Brickshelf If you want to take a look on the building process, please click here Thanks for reading Quote
MetroiD Posted March 14, 2012 Posted March 14, 2012 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? Quote
