Connect the battery that will be used on the MHD boat to the circuit instead of the laboratory power supply, verify that no changes occur in the circuit due to this change in power sources. 4.4 Directional Control The following procedure will be used to test the functionality of the directional control circuitry: Verify that the initial position of the rudder is straight, meaning in line with the bow and stern of the MHD boat. Test the maximum turning angle of the rudder; ensure that the angle is not beyond the designed angle, as a stall can occur if this condition is not functioning correctly. Check the speed that the rudder turns in reference to the distance the rudder has to travel for desired position. If the direction control subsystem is not mounted on the MHD boat, simulate the expected maximum flow that the MHD will experience. Verify that the rudder functions correctly under these conditions and that the servo motor has the power to turn the boat with the added water resistance. 4.5 Boat Hull Testing Testing the watertight integrity and weight balancing of the constructed boat will a very important step to be performed before the building process. We will use the following method: Place the boat in water and observe whether it is properly balanced and not leaning to one side of another. Using a 15 pound weight place it in the boat and leave it for about 1 hour. Upon returning carefully inspect the boat for leaks or water of any kind. With a 3 weight, tape it to all four sides, one at a time to ensure that the boat will be able to withstand small amounts of unbalanced weight without tipping.
