An azipod is an azimuth thruster, an engine and ship's propeller in an underslung pod which is azimuth adjustable.
It's free on sometimes.
In 1912, Titanic was built to the tune of $7.5M US. There is a Titanic hotel being built in China (as of 2017) but there is no propulsion so it's not quite the same thing.
Umm...the question is a little vague (is it for a project, are there more details?), so I'll offer as much as I find relevant. You can split it into arm propulsion or leg propulsion. You can split it into the four strokes: butterfly, backstroke, breaststroke, freestyle. You can split it into surface propulsion and underwater propulsion. Be more specific and I can help you more.
The three main propulsion types are chemical propulsion, electric propulsion, and nuclear propulsion. Chemical propulsion uses chemical reactions to generate thrust, electric propulsion uses electric power to accelerate propellant to high speeds, and nuclear propulsion uses controlled nuclear reactions for propulsion.
The question is a real tough one to crack, but given the advances in physics and science much research is underway to built a UFO and the basic strategies pursued could be one or many incorporated of the following: 1)Electro-gravitic propulsion 2)Plasma propulsion 3)Magneto-hydrodynamic propulsion 4)Fusion propulsion 5)Inertial propulsion
Propulsion
Jet propulsion improved airplane flights. Before that piston engines were used. They were much slower compared to the jet engine.
Some synonyms for propulsion are drive, energy, momentum, power, speed, or thrust. Propulsion is a noun, there is no antonym except 'no propulsion'.

The aircraft's propulsion comes from its engines.
Propulsion is a noun, not a verb. Only verbs have tenses.
