At the same time, with a petrol engine is counter installation electric launchers, which a spark can ignite gasoline. In the second stage we decide to power on the motor shaft. The catalog company Vetus 2009 proposed an example of calculating electric power to neutralize the varying wind force. Determine the effectiveness of the steering device, in this case, will force all the way, not horsepower or kilowatts. Necessary to calculate the power of IP to the penalty area with a yacht of the wind at 18 m2 average wind pressure 60 N/m2, which corresponds to the wind force 5 Beaufort. Calculation of the torque: T = wind pressure * area * impact factor 0.75 * distance from the center of the force of wind to the edge of the stern (Approximately equal to half the length of the vessel). T = 60 N/m2 * 18 m2 * 0.75 * 11 / 2 m = 4455 Nm calculated required capacity of PU F = torque T / CP and the distance between the turning point (the edge of the stern) = 4455Nm / 10.5 m = 420N (42 kg) should be remembered that the effectiveness of CP for each ship is different, because the court characterized the shape of the underwater part and the location of the CP.
At the planning stage you need to consider the installation of PU equipment, provide all accessories. For example, a hydraulic PU minimum consists of the following: 1. The hydraulic pump driven by main engine, generator, or a special own engine. 2. Hydraulic. 3.
Tank for hydraulic fluid to the attached nodes control and regulation. 4. Coupling high-pressure hoses. It remains to determine the manufacturer of the steering device, but it's also not an easy task. A huge number of dealers offer many products manufacturers. And a guide in choosing, in addition to the cost and the recommendations of friends sailing, must be the presence service and a wide dealer network, because you do not know what country it may be faulty. Certification of local oversight services will also help avoid many unpleasant questions. It should be noted that the company Vetus thrusters is a decent choice for ship owners seeking to maximum convenience and carefree swimming. PU are unyielding to rust propellers unique shape that ensures equal emphasis on both sides. IP tunnels, made of steel, aluminum or fiberglass can be fitted to any vessel. Thrusters Vetus low noise and can operate at maximum power for several minutes.
