Model Forum / Radio Controlled / Water Models / May 2005Waterjet and towing?
Hey all, I was wondering how effective it would be to place a waterjet system into a boat an use it for towing? It would seem to be similar to a prop in a kort nozzle. What are your thoughts? Thanks > Hey all, > > I was wondering how effective it would be to place a waterjet system into a > boat an use it for towing? It would seem to be similar to a prop in a kort > nozzle. What are your thoughts? Thanks In principle, it will work, but not very effectivly. At low speeds the diameter of the propeller is important, a large propeller at low speed can produce thrust much more effectivly than a small propeller running at higher speed, and the "propeller" in a waterjet is allways rather small. Maybe someone knows whether a diffusor or a mixer behind the jet improves the situation. There should be some experience from side thrusters in big ships, but they seem to get larger and larger in diameter over time. |
