My idea is a new type of propellers. Propellers, designed with the most intelligent programs and created the most modern equipment, came to its limit. An attempt to move to a high functional and technological level. I would like to know the views of professionals about the prospect of using PROPELLER WITH THE CUMULATIVE EFFECT both water transport and on the air. Details on the website: http://propeller-e.ucoz.com/ Prototype no. I beg you, relying on intuition, product knowledge and experience to express their opinion in a poll on this site. I would be grateful to those popular and more will present their thoughts.http://propeller-e.ucoz.com/1.gif |

I am not an engineer but I am a pilot of a Viking and a Boat Captain. My boat has props that are 28 inch diameter and 29 inch pitch and turn at 1000 RPM. This pushes the boat at 18 knots yielding an efficiency of around 75%. My Viking (IO 520D 300 HP with 74 inch McCauley prop) pulls my Viking at 160 knots at 2300 RPM. The Viking prop encompasses 9 times the area of the boat wheels, and turns 23 times as fast. I cant see how the two applications can use the same prop. Too much difference in the viscosity of the materials. |
