What is a propulsion pod on a cruise ship?

What is a propulsion pod on a cruise ship?

POD is one type of azimuth propulsion consisting of an integrated electric motor / propeller unit mounted on the same shaft, installed in a gondola under the stern of the ship. The gondola revolves around a vertical axis suitably orienting the propeller so as to control the direction of motion.

What is a pod drive motor?

Pod drives are a marine power system that eliminates the need for shafts, struts, and rudders. Instead of using traditional running gear to transfer the engine’s power into thrust, a “pod,” consisting of the transmission, outdrive, and propeller(s), is mounted right through the bottom of the boat.

What are pod drives?

Pod drive is a marine propulsion system where the gearbox and drive is mounted right beneath the boat in the water. They steer on a large axis, and when mounted in twin and triple set-ups can be used with a joystick for ease of parking.

How do boat pods work?

The pods extend beyond the transom and add extra floatation to lift the back end up out of the water which is the heaviest part of the boat. Reduces how far the transom of the boat sits in the water helping to compensate for the weight of the outboard motor and batteries.

What are Zeus drives?

Enhanced Protection. Zeus features rear-facing propellers and a tunnel-mounted design that protects the pod drive from underwater debris. Most floating objects will be deflected downward by the keel and skeg, away from the propellers.

What is electric propulsion for ships?

Electric propulsion systems utilize electrical power to drive propeller blades for propulsion. From commercial and research ships through to fishing vessels, over recent years, electric propulsion has gained momentum in a wide range of marine applications across Europe and in Japan.

What is an azimuth drive?

Azimuth thrusters, also called azipods, are propellers mounted in a pod that provides thrust and steering by rotating the unit horizontally. Traditionally, vessels have propellers that provide forward thrust and a rudder that produces drag by turning, steering the vessel.

Is an electric spaceship possible?

An electric rocket with an external power source (transmissible through laser on the photovoltaic panels) has a theoretical possibility for interstellar flight. However, electric propulsion is not suitable for launches from the Earth’s surface, as it offers too little thrust.

Can you produce thrust with just electricity?

Electric propulsion technologies generate thrust via electrical energy that may be derived either from a solar source, such as solar photovoltaic arrays, which convert solar radiation to electrical power, or from a nuclear source, such as a space-based fission drive, which splits atomic nuclei to release large amounts …

How much do flotation pods help?

Our Flotation Pods not only increase the plane of your boat, but also offer up to 200 LBS. of extra flotation. This extra flotation helps to off-set the negative performance often associated with the extra weight of a conventional 4-stroke air-cooled motors.

How much does a Zeus pod cost?

Each IPS has anodes as well, one up inside the exhaust tunnel (the other is on the transom); both Zeus anodes are on the trim tabs where they’re easy to reach. Allow $450 per IPS pod, $350 per Zeus.

Who makes Zeus pod drives?

As leaders in marine propulsion innovation, Cummins is proud to introduce Zeus®, the world’s most advanced marine propulsion system. The result of 15 years of research and testing, Zeus pod propulsion delivers a whole new level of performance, fuel efficiency, protection and vessel control.

What is electric propulsion system?

Electric Propulsion (EP) is a class of space propulsion which makes use of electrical power to accelerate a propellant by different possible electrical and/or magnetic means. The use of electrical power enhances the propulsive performances of the EP thrusters compared with conventional chemical thrusters.

What are the types of electric propulsion system?

There are three basic types of electric propulsion systems, categorised according to the method used to accelerate the propellant as electrothermal, electrostatic, and electromagnetic. Practical propulsion systems frequently make simultaneous use of two or even all three of these methods.
