The Power of Water Jet
The JET drive or water jet drive is mainly used for exclusive and fast yachts, ferries, racing boats, etc. Respectively. In principle, this drive consists of a pump, which sucks the water through an opening at the bottom of the ship, accelerates via an impeller and ejects through an opening in the rear again. Here the Newtonian law applies, according to which the backward jet of water produces an equally great forward reaction to the boat body. The boats with jet propulsion can drive in very shallow water, since all the parts under the boat body such as propeller, shaft, rudder and rudder are missing. In addition, the approach acceleration is very high, which is particularly advantageous for dragster boats. There is also no heeling moment, as in a conventional ship propeller. Since the water in a JET drive must travel long distances in narrow ducts, friction losses occur which require a little more energy than in a conventional drive.
When the reversing device is actuated, the water jet can be deflected forward so that the ship moves backwards. For high efficiency the engine speed should be reversed
Only 1/3 to 1/2 the maximum speed.
The model builder has many possibilities through his own attempts to adjust the efficiency of the drive to the own model and still improve. Suitable for SPEED 600 series electric motors.
BRUSHLESS motors can also be used at their own discretion.
- The Mini-JET is used in the model MULTI JET BOAT No.2155.V2 , but can also be used for other small and medium-sized boats. It allows very precise steering both forward and reverse. All parts are injected from plastic. The shaft of Ø 3 mm steel is double sintered and sealed on one side.
