dbo:abstract
Preliminary Research Aerodynamic Design to Lower Drag, or Prandtl-D was an unmanned experimental glider-aircraft developed by NASA. The acronym is a reference to early German Aerospace Engineer Ludwig Prandtl. The Prandtl-D was a tailless glider that is based on the flight of birds. Birds turn and bank without vertical tails that are required for such maneuvers on traditional aircraft. It was intended to provide for future low drag and experimental aircraft designs, which previously have had issues of controllability. The program reinforced similar wing designs by Ludwig Prandtl which were conceptualized a century before. The Prandtl-D's designs were also based on glider concepts of German brothers Reimar and Walter Horten and incorporate the conclusions of NASA aerodynamics pioneers R.T. Jones and Richard T. Whitcomb. The Prandtl-D1 and the Prandtl-D3 models were featured in the National Air and Space Museum and the California Science Center, respectively. Albion Bowers, NASA Armstrong chief scientist and Prandtl-D project manager, brought together the theories and has led the effort with help from student interns. He believes that with the concepts proven under the Prandtl-D "the time may be coming for a new paradigm in aviation."
