Download or read book Results of Two Free-fall Experiments on Flutter of Thin Unswept Wings in the Transonic Speed Range written by WIlliam T. Lauten and published by . This book was released on 1951 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of four thin unswept flutter airfoils attached to two freely falling bodies are reported. Two airfoils fluttered at a Mach number of 0.85, a third airfoil fluttered at a Mach number of 1.03, and a fourth fluttered at a Mach number of 1.07. Results of calculations of flutter speed using incompressible and compressible air-force coefficients, including Mach number of 1.0, are presented.
