Suggestions for article titles:

1. Propulsion: Propulsion means to add speed or acceleration to an object, by an engine or other similar device. The word 'propulsion' can be used with many other words (such as jet, rocket, spacecraft) to become-'jet propulsion', 'rocket propulsion', or 'space ... [100%] 2024-01-04 [Engineering] [Aerospace engineering]...
2. Propulsor: A propulsor is a mechanical device that gives propulsion. The word is commonly used in the marine vernacular, and implies a mechanical assembly that is more complicated than a propeller. (Engineering) [77%] 2023-11-08 [Marine propulsion]
3. Vehicle classification by propulsion system: There are numerous versions of vehicle propulsion systems. Many of those came into fruition due to need for cleaner vehicles. (Engineering) [73%] 2023-12-17 [Vehicle design]
4. Spacecraft propulsion: Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry. (Astronomy) [70%] 2023-11-02 [Spacecraft propulsion] [Spacecraft components]...
5. Marine propulsion: Marine propulsion encompasses the technologies used to drive ships through the water, and sometimes also to steer them. In the basic cases, the requirement is to spin the propellers. [70%] 2023-06-22
6. Propulsion transmission: Propulsion transmission is the mode of transmitting and controlling propulsion power of a machine. The term transmission properly refers to the whole drivetrain, including clutch, gearbox, prop shaft (for rear-wheel drive vehicles), differential, and final drive shafts. (Engineering) [70%] 2023-11-14 [Mechanical power transmission] [Mechanisms (engineering)]...
7. Marine propulsion: Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric ... (Engineering) [70%] 2023-10-29 [Marine propulsion]
8. Jet propulsion: Jet propulsion is the propulsion of an object in one direction, produced by ejecting a jet of fluid in the opposite direction. By Newton's third law, the moving body is propelled in the opposite direction to the jet. (Thrust produced by ejecting a jet of fluid) [70%] 2024-01-04 [Energy conversion] [Aquatic locomotion]...
9. Self-propulsion: Self-propulsion is the autonomous displacement of nano-, micro- and macroscopic natural and artificial objects, containing their own means of motion. Self-propulsion is driven mainly by interfacial phenomena. (Physics) [70%] 2023-11-15 [Mechanical engineering] [Surface science]...
10. Reactionless propulsion: Reactionless propulsion, "support-less propulsion", or "inertial propulsion" are all names of a technological concept of an engine that moves a spacecraft without using any external body to push from, and without jettisoning any of its parts. In other words ... [70%] 2023-06-26
11. Field propulsion: Field propulsion is the concept of spacecraft propulsion where no propellant is necessary but instead momentum of the spacecraft is changed by an interaction of the spacecraft with external force fields, such as gravitational and magnetic fields from stars and ...

12. Berg Propulsion: Berg Propulsion is a Swedish company that designs and manufactures controllable-pitch propellers for the marine industry. The company produces customized main propellers, azimuth thrusters, transverse thrusters and manoeuvre systems.

13. Laser propulsion: Laser propulsion is a form of beam-powered propulsion where the energy source is a remote (usually ground-based) laser system and separate from the reaction mass. This form of propulsion differs from a conventional chemical rocket where both energy ... (Engineering) [70%] 2023-11-11 [Spacecraft propulsion] [Emerging technologies]...
14. Ship propulsion: Ship propulsion refers to the method of moving a ship through the water. The three main types are oars, sails, and mechanical means. [70%] 2023-10-30
15. Laser propulsion: Laser propulsion is a form of beam-powered propulsion where the energy source is a remote (usually ground-based) laser system and separate from the reaction mass.

16. Electromagnetic propulsion: Electromagnetic propulsion (EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The electrical current is used to either create an opposing magnetic field, or to charge a field, which can ...
