    • Blown flap noise 

      Haas Martin (Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1972], 1972)
      This report is concerned with the noise generated by blown flaps of the type currently being developed for the short take off and landing aircraft. The majority of the report is an experimental study of the sound-radiation ...

    • The development of a wind tunnel facility for the study of V/STOL noise 

      Widnall, S. E.; Bauer Paul E. (Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1972], 1972)
      An open-jet wind tunnel operating within an anechoic chamber was developed for the purpose of the study of V/STOL noise mechanisms. An existing low-speed conventional hard-walled wind tunnel was modified to operate as an ...

    • The interaction of sound with turbulent flow 

      Succi, G. P. (George Peter) (Cambridge, Mass. : Massachusetts Institute of Technology, Gas Turbine & Plasma Dynamics Laboratory, [1977], 1977)
      Introduction: In the now classical theory of sound from turbulent flow by Lighthill boundaries were not considered. Further, it was assumed that the turbulent flow field was not altered by sound emission. For closed systems, ...
