We drive the car forward, air from the opposite direction enters the air turbine. It first passes through the filter then through the flap and comes to the turbine, turns it at high speed and the air escapes into the atmosphere.
The turbine rotates the generator over the shaft, the generator produces electricity which is stored in the battery via a cable. The rechargeable battery drives the electric motor, the electric motor drives the wheel axle.
In the system we have a gear pump with its oil tank that hydraulically opens or closes the flap when the battery signals via a sensor that it needs charging, then the pump starts, opens the flap, air enters and turns the turbine, the turbine turns the generator and we get electricity and charge the rechargeable battery until the sensor gives a signal that the battery is charged and then the pump closes the flap and shuts down.
We always have another spare battery in the system.
Since we know that the generator must maintain a constant number of revolutions to obtain the required voltage to supply electricity to the battery, in the system we have a regulator that receives a signal from the sensor (That the battery needs to charge), the regulator gives a signal to the gear pump, the pump starts and hydraulically opens the flap, air enters and the regulator through the pump on the flap maintains a constant number of revolutions of the generator (by leaking more or less air by opening or closing the flap) so that the generator maintains the speed given to it, and we get the necessary voltage and electricity to charge the battery, when the battery is charged, the sensor gives a signal to the regulator and the flap is closed by the hydraulic pump then the turbine and generator fall out of use.
The system in the propulsion of the ship is the same as in the car, the principle of operation is the same, the only difference is that the fluid here is water, not air.
The generator rotation control is the same.
The only difference is that we have filth in the sea, so we have an anti-flush pump in the system, which we start automatically in the voyage to wash the filter (Because this pump has a separate suction and with a pressure higher than that in the system and occasionally washes the filter.). In the harbor filter needs to be cleaned, we have built-in valves in front of and behind the filter that we close and clean the filter.
