      <title>RAM WING SURFACE EFFECT BOAT</title>
      <link>https://trid.trb.org/View/4700</link>
      <description><![CDATA[The development of an efficient, stable, self-trimming ram wing vehicle for operation over water is described.  It has long been recognized that low aspect ratio (and, therefore, structurally efficient) wings have very high lift over drag ratios when operated in close proximity of a surface.  An apparent static pitch and heave instability has prevented the design of practical ram wing vehicles until recently. This paper describes the design, wind tunnel testing and radio controlled model testing of a two man ram-wing boat, which (at full scale) would have a gross weight of 1500 pounds, cruise at 70 miles per hour over one foot waves and require thirty horsepower.]]></description>

      <title>DEVELOPMENT OF THE AXIAL FLOW SURFACE EFFECT VEHICLE</title>
      <link>https://trid.trb.org/View/4702</link>
      <description><![CDATA[This paper reviews development of the axial flow surface effect vehicle, which is propelled clear of the surface by lift air, and cruises at a velocity two to four times as fast as a comparable hovercraft.  A study based on a generalized edgeflow analysis illustrates the performance potential.  Aerodynamic effects are more significant than aerostatic effects for this type which operates at a ram pressure equal to or higher than cushion pressure.]]></description>
