      <title>WATERJET PROPULSION FOR FAST CRAFT - OPTIMIZED INTEGRATION OF HULL AND PROPULSOR</title>
      <link>https://trid.trb.org/View/479921</link>
      <description><![CDATA[This paper examines the challenges associated with the correct selection of waterjet propulsors for a vessel designed to perform a given mission or meet a set of specific operational requirements. When the primary purpose of a proposed new ship has been defined in terms of payload, range, speed, endurance, sea state and other environmental factors, the ship design proceeds as an iterative process to define the optimum hull geometric parameters, the optimum propulsor type and size, the internal arrangements, auxiliary equipment and many other important features.  The object of the exercise is to arrive at the ship design which best meets the requirements of the mission with the minimum financial outlay and the maximum economic return.  The use of a whole-ship design integration tool is described to show how the above objective is achieved with waterjets and the chosen method of propulsion.]]></description>

      <title>NOISE FROM WATERJET PROPULSION</title>
      <link>https://trid.trb.org/View/479970</link>
      <description><![CDATA[A classification and general discussion of different noise sources, such as inlet and impeller cavitation, turbulence in the flow and jet impingement, introduces the main subject of the paper; blade frequency related tonals.  Harmonics of the blade passage frequency, which in some cases can be a dominating noise source in the low frequency range, can be detected as pressure pulses in the inlet duct, underwater acoustic noise, or vibrations and airborne noise within the ship.  Parameters influencing the generation of these tonals, such as the velocity distribution in front of the impeller, the type and extent of cavitation, are discussed, as well as different techniques for noise-control.  A new impeller design is presented. Experimental results support the conclusion of the paper, that significant reduction of low frequency noise can be obtained without sacrificing the pump performance in terms of efficiency and cavitation properties.]]></description>

      <title>A NOVEL FLUSH INLET DESIGN METHODOLOGY FOR WATERJET PROPULSION</title>
      <link>https://trid.trb.org/View/479972</link>
      <description><![CDATA[One of the important areas in waterjet propulsion for marine vehicles is the design of inlet shapes.  For efficient operation of a waterjet propulsion system, the inlets are required to operate efficiently over a wide range of mass flows, vehicle speeds, and incidence angles.  Furthermore, impeller inlet distortion has to be minimized in order to improve the impeller efficiency and reduce vibration and cavitation problems.  Other considerations such as the stern shaping and inlet location are also important in the design of high performance inlets.  This paper develops a design methodology for high performance flush inlet for a wide range of operating conditions.]]></description>

      <title>CONTROVERSIAL ISSUES IN WATERJET-HULL INTERACTION</title>
      <link>https://trid.trb.org/View/480026</link>
      <description><![CDATA[The paper discusses the intake drag of a flush intake, the effect of interaction in a potential flow and the lift production by the waterjet.  It is shown that there is no drag of a flush intake in a non- viscous flow, that there is not a potential pressure or velocity effect in the powering characteristics due to interaction and that there is no net lift production by a waterjet.  The effect on hitherto published efficiency equations is demonstrated and a proper model accounting for the interaction if proposed.]]></description>

      <title>MANOEUVRABILITY OF WATERJET-PROPULSED PASSENGER FERRIES</title>
      <link>https://trid.trb.org/View/480056</link>
      <description><![CDATA[This paper deals with various aspects of the manoeuvrability of waterjet propelled fast ferries at low speeds.  To achieve quick berthing manoeuvres the fast ferry must be equipped with manoeuvring enhancing devices such as joy-stick, single lever control systems.  The following aspects are discussed 1) waterjet power requirements and restrictions during low speed berthing/unberthing manoeuvres, 2) required settling times of waterjet bucket-position and steering angles in conjunction with displacement, available thrust and craft geometry, 3) control system integrity and crew awareness with special attention to the need for duplication of functions and devices and 4) man-machine interfacing improvements by intelligent alarming.]]></description>

      <title>A NUMERICAL ANALYSIS OF THE FLOW AROUND THE WATERJET INLET</title>
      <link>https://trid.trb.org/View/480071</link>
      <description><![CDATA[In this paper the flow field around the waterjet inlet is studied numerically by including ship's hull effects.  The inlet flow is estimated by a potential-based higher-order boundary-element method, in which the free surface boundary conditions is approximated by its high speed limit.  Then the local flow around the waterjet is simulated by using a 3-D viscous code.  A flush-type waterjet inlet installed in a mathematical hull is considered and the numerical results are compared with experimental data.  The primary concern is to examine the flow performance in terms of pressure distribution.  It is found that the pressure distribution is affected by ship's hull and viscous effects have to be included in order to predict it correctly.]]></description>

      <title>FIRST JET HOVERCRAFT DEVELOPED BY MES</title>
      <link>https://trid.trb.org/View/430777</link>
      <description><![CDATA[MES, of Japan, have developed the Mitsui Jet Hover, a high-speed waterjet- propelled hovercraft which will be made available in various sizes able to carry from 20 to 1000 passengers; it is particularly suitable for operation in shallow rivers and lakes and on coastal and inland-sea routes.  A diesel-driven waterjet is carried in each of the craft's two skegs; a flexible skirt is fitted, and air is blown into the space below the hull as in conventional hovercraft.  A motion-control system controls the air-pressure to ensure riding comfort, fin stabilisers are fitted, and the skegs assist coursekeeping and stable running; there are virtually no stern waves.  A prototype, named the EAGLET, has performed well during extensive sea-trials, and has the following principal particulars: length oa 10.9m; breadth oa 5.1m; depth 0.89m; propulsion by two 98hp Nissan Marine gasoline engines driving Hamilton waterjets; two 22hp Robin gasoline engines driving two centrifugal air-cushion fans; max. speed about 27 knots.]]></description>

      <title>JET-PROPELLED REMOTE-OPERATED UNDERWATER VEHICLES GUIDED BY TILTING NOZZLES</title>
      <link>https://trid.trb.org/View/433847</link>
      <description><![CDATA[This paper is a study and experimental analysis of a forced jet propulsion system with tilting-type nozzles for slow-moving remotely operated underwater vehicles (ROVs). A test setup simulating the motion of the underwater vehicle was fabricated to investigate the effect of nozzle configurations on the propulsion of such vehicles. Plexiglass nozzles of different conical contraction angles (4 - 28 degrees), different conical expansion angles (3 - 9 degrees) and a straight cylindrical section were used in the study. Tests were carried out underwater and the parameters measured include thrust, flow rate, angular velocity and total head. Different circular disk type drag plates were used to simulate the drag of the vehicle underwater. Efficiency of propulsion is the criterion for comparing the performance of each nozzle. An expression for the optimum efficiency was derived neglecting the effect of inlet head recovery, which can be assumed for slow-moving vehicles. The energy loss and loss coefficients in submerged propulsion nozzles were found both theoretically and experimentally. A proposal for the fabrication and testing of an innovative design for a jet-propelled ROV guided by tilting nozzles is presented. The design uses a stepper motor for tilting the nozzles. A comparison is made between stationary and swivel-type configurations. The nozzles were tested for optimum area ratio. The propulsion system and the ROV were designed and checked for stability. The study revealed that, for a range of flow rates, one particular nozzle was the most efficient.]]></description>
