Pump-jet - Wikipedia
A pump-jet, hydrojet, or water jet is a marine system that produces a jet of water for propulsion. The mechanical arrangement may be a ducted propeller (axial-flow pump), a centrifugal pump, or a mixed flow pump which is a combination of both centrifugal and axial designs.
Understanding Water Jet Propulsion - Working Principle, Design …
Jul 27, 2021 · Water Jet Propulsion is a popular form of propulsion system used in the marine industry. Let's take a look at water jet propulsion, its working principle, and the advantages that offers.
Jet propulsion - Wikipedia
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.
Jet Drive - boats.com
Oct 10, 2018 · Jet drives have long had their place in marine propulsion. Here’s a breakdown of their strengths and weaknesses. You will find jet drive propulsion systems on everything from personal watercraft, to family runabouts to giant passenger ferry boats.

How do jet engines work? | Types of jet engine compared
Oct 27, 2024 · A jet engine is a machine that converts energy-rich, liquid fuel into a powerful pushing force called thrust. The thrust from one or more engines pushes a plane forward, forcing air past its scientifically shaped wings to create an upward force called lift that powers it …
The Different Types of Yacht Propulsion: Benefits and Drawbacks
Aug 18, 2020 · Jet Drive Propulsion Illustration. Illustration of a Jet Drive Propulsion System. The jet drive is very common today in runabouts and tenders, primarily because of the perceived safety of the propeller (called an impeller here) being …
Marine propulsion - Wikipedia
A pump-jet, hydrojet, water jet, or jet drive uses a ducted propeller (axial-flow pump), centrifugal pump, or mixed flow pump to create a jet of water for propulsion. These incorporate an intake for source water and a nozzle to direct its flow out, generating momentum, and in most cases, employing thrust vectoring to steer the craft.
Water-Jet Drives - Yachting
Oct 4, 2007 · Jet drives steer the boat with vectored (aimed) thrust, providing unmatched maneuverability, including the ability to precisely hold a boat in a fixed position against the effects of current and wind. The jet drive avoids the asymmetric thrust produced by propellers mounted on inclined shafts.
Jet Propulsion - an overview | ScienceDirect Topics
Jet propulsion refers to the technology that drives vehicles by spraying high-speed airflow. The principle of jet propulsion is to use high-temperature and high-pressure gas released after fuel combustion [117], which is sprayed out through the nozzle to form high-speed jet airflow, generating thrust. Jet propulsion has the advantages of high ...
