Download or read book Two dimensional Investigation of Five Related NACA Airfoil Sections Designed for Rotating wing Aircraft written by Raymond F. Schaefer and published by . This book was released on 1949 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five NACA airfoils intended for use in rotor blades have been designed and the two-dimensional aerodynamics have been determined at three Reynolds numbers up to 2,600,000. The airfoils vary in thickness from 9 to 15 percent chord and in design lift coefficient from 0.3 to 0.7. The relative performance of sample rotors employing the different airfoils is predicted for various flight conditions.

Loftin and published by . This book was released on 1946 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A two-dimensional wind-tunnel investigation was conducted to determine the aerodynamic characteristics of the NACA 65(215)-114 airfoil (root section), the NACA 65,1-212, a = 0.6, airfoil (tip section), and an intermediate airfoil section of the Chance-Vought XF6U-1 airplane.

This book was released on 1965 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Force and moment data are presented from wind tunnel tests of two-dimensional symmetrical NACA 63A-Series airfoils of thickness ratios from 9 to 18 percent. The tests were conducted at Mach numbers ranging from M = .30 to M = .94 with Reynolds numbers varying from R = 2.0 X 1,000,000 to R = 9.5 X 1,000,000 and at angles of attack as high as 29 degrees. Comparisons are made, wherever possible, with NACA tests of the same or similar airfoils. The transonic similarity rule is used to evaluate the consistency of the data. (Author).
Download or read book Helicopter Theory written by Wayne Johnson and published by Courier Corporation. This book was released on 1994-01-01 with total page 1126 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of the helicopter may be traced back to the Chinese flying top (c. 400 BC) and to the work of Leonardo da Vinci, who sketched designs for a vertical flight machine utilizing a screw-type propeller. In the late 19th-century, Thomas Edison experimented with helicopter models, realizing that no such machine would be able to fly until the development of a sufficiently lightweight engine. When the internal combustion gasoline engine came on the scene around 1900, the stage was set for the real development of helicopter technology. While this text provides a concise history of helicopter development, its true purpose is to provide the engineering analysis required to design a highly successful rotorcraft. Toward that end the book offers thorough, comprehensive coverage of the theory of helicopter flight: the elements of vertical flight, forward flight, performance, design, mathematics of rotating systems, rotary wing dynamics and aerodynamics, aeroelasticity, stability and control, stall, noise and more. Wayne Johnson has worked for the U.S. Army and NASA at the Ames Research Center in California. Through his company Johnson Aeronautics, he is engaged in the development of software that is used throughout the world for the analysis of rotorcraft. In this book, Dr. Johnson has compiled a monumental resource that is essential reading for any student or aeronautical engineer interested in the design and development of vertical-flight aircraft.
