      <title>A GUIDE TO ASSESS THE OPERATIONAL IMPLICATIONS OF NEW SHIP DESIGN CONCEPTS. PART III</title>
      <link>https://trid.trb.org/View/23341</link>
      <description><![CDATA[This report covers concluding work performed for the Office of Naval Research, Naval Analysis Programs, under Contract N00014-70-C-0426. Two previous reports have been published under the same title: Part I, ORI TR 667, 11 June 1967, AD 728003; Part II, ORI TR 741, 22 March 1973, AD 759376. Part 3 provides basic guidance and understanding to the planning analyst in the area of inherent operational advantages and limitations of the three major high-performance ship concepts under development today: (1) Small-Waterplane-Area Twin-Hull (SWATH); (2) submerged-foil hydrofoil; and (3) Air Cushion Supported Vehicles (ACV and SES). Many other concepts are briefly introduced. Concept descriptions, basic trade-offs, basic operational qualities, size range limitations and operational implications/potential applications are included. Discussion tends to be subjective and is designed to alert the analyst to potential problem areas rather than provide quantitative assessment of the concepts. (Author)]]></description>

      <title>APPLICATION OF WATERJET PROPULSION TO HIGH-PERFORMANCE BOATS</title>
      <link>https://trid.trb.org/View/51970</link>
      <description><![CDATA[A review of history and development of waterjet technology and its application to military and commercial use is presented.  A review of waterjet characteristics and current performance is summarised, and influencing elements of a waterjet system affecting overall performance are identified.  The issue of propulsion efficiency and its proper place in evaluating waterjet propulsors is discussed. A summary of current craft utilising waterjets is presented and designs of waterjets used for several different applications and horses-powers are presented.  Specific designs for the Boeing Jetfoil and the crewboat, American Enterprise, are reviewed.]]></description>

      <title>FULL-SCALE TRIALS AND ANALYSIS OF HIGH-PERFORMANCE PLANING CRAFT DATA</title>
      <link>https://trid.trb.org/View/72669</link>
      <description><![CDATA[Comparisons are given for predicted and full-scale speed-power-RPM data for planing craft.  The results indicate that correlation is significantly influenced by propeller cavitation and its uncertain effects on propulsive factors.  Correlation factors are offered for both horsepower and RPM with indications that careful attention to underwater design details is very important for speeds above 25 knots.]]></description>

      <title>MARINE PROPULSION</title>
      <link>https://trid.trb.org/View/50385</link>
      <description><![CDATA[Nine papers by various authors are presented.  The topics discussed include: high performance ship propulsion systems; thrust augmenters; high performance marine propellers; waterjet propulsion; gas-augmented waterjet propulsion; intermittent propulsors; electric propulsion; marine batteries; and high energy density marine fuel cell systems. Individual papers are indexed separately.]]></description>

      <title>RECOMMENDED VEHICLE CONCEPTS FOR WATERJET PROPELLED HIGH-PERFORMANCE VEHICLES</title>
      <link>https://trid.trb.org/View/23895</link>
      <description><![CDATA[A rapid method is developed for providing first order estimates of the smooth water powering and weight characteristics of SES, hydrofoil, and planing craft concepts employing waterjet propulsors. A computer program utilizing this method and applicable to SES concepts is included.]]></description>

      <title>PARAMETRIC ANALYSIS FOR THE CONCEPTUAL DESIGN OF HIGH PERFORMANCE SHIPS</title>
      <link>https://trid.trb.org/View/23105</link>
      <description><![CDATA[This paper presents an application of the use of parametric analysis techniques to support the conceptual design of high performance ships.  The objectives of parametric analysis are identified.  Using concrete examples, the paper demonstrates how these objectives can be met. Parameters of interest are identified, and the techniques and assumptions necessary to accomplish the analysis are presented. The 2000-ton Surface Effect Ship (2KSES) is used in the sample design problem.]]></description>
