1. 1. Electrically powered manoeuvring of water jets

   University essay from Uppsala universitet/Industriell teknik

   Author : Joel Engström; [2021]
   Keywords : Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

   Abstract : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

3. 2. Design and system integration of a rim jet solution utilizing DFMA

   University essay from KTH/Integrerad produktutveckling

   Author : Gustav Adolf Adler; [2020]
   Keywords : ;

   Abstract : Moving a new innovative idea from the drawing board to production is no easy feat. The Swedish sea rescue society (SSRS) has for the past years fostered a new design solution for their jet skis, a alternative water jet that removes the centre hub and utilises rim drive technology.

4. 3. Analysis of the intake grill for marine jet propulsion

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Marcus Söderberg Jansson; [2019]
   Keywords : Intake grill; Waterjet; Fluid Dynamics; Intagsgaller; Vattenjet; Strömning;

   Abstract : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. READ MORE

5. 4. Rim-Jet - A Mechanical Design for a Shaft-less Propulsor

   University essay from KTH/Maskinkonstruktion (Avd.)

   Author : Pablo Sanchez Santiago; [2019]
   Keywords : Conceptual design; debris; propulsor; rescue operations; verify; Driftsäkerhet; framdrivning; propulsor; räddningsbåt; Sjöräddning;

   Abstract : During sea rescue operations it is common for the rescue vessels to operate in water with high number of debris that can get stuck in the propulsor. In particular plastic ropes that can get tangled around the shaft and melt causing a complete stop or damage the motor. READ MORE

6. 5. Water jet steering concept : - evaluation of an environmental design, Part 1

   University essay from Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Viola Örtegren; [2014]
   Keywords : water jet; environmental evaluation; simulation; force; fatigue; kraftöverföring; kraftpåverkan; vattenjet; miljölvänlig; koncept; simulering; utmattning;

   Abstract : The current hydraulic system that function as the power source for operating the water jet steering device, need to be located inside of the hull to avoid possible environmental damage. This will cause a height difference from where the power supply will be located and where the output is needed. READ MORE
