Flutter Investigation in the Transonic Range of Six Airfoils Attached to Three Freely Falling Bodies
Results of Two Free-fall Experiments on Flutter of Thin Unswept Wings in the Transonic Speed Range
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 a Mach number of 1.0, are presented
