To fill that void in technical data, NASA (National Aeronautics and Space Administration) commissioned the highly respected practicing engineers and authors W. Z. Stepniewski and C. N. Keys to write one. The result: Rotary-Wing Aerodynamics, a clear, concise introduction, highly recommended by U.S. Army experts, that provides students of helicopter and aeronautical engineering with an understanding of the aerodynamic phenomena o 410 0$aDover books on aeronautical engineering 606 $aHelicopters$xAerodynamics 606 $aMechanical Engineering$2HILCC 606 $aEngineering & Applied Sciences$2HILCC 606 $aAeronautics Engineering & Astronautics$2HILCC 606 $aHelicòpters$xAerodinàmica$2lemac 615 0$aHelicopters$xAerodynamics. 615 7$aMechanical Engineering 615 7$aEngineering & Applied Sciences 615 7$aAeronautics Engineering & Astronautics 615 7$aHelicòpters$xAerodinàmica 676 $a629.132/3 700 $aStepniewski$b W.
