Book excerpt: The power spectrum of relatively short wavelength turbulence in the atmosphere was calculated from measurements made in flight. The range of wavelengths covered by these measurements was from 10 feet to 200 feet. The power spectral density varies with the square of the wavelength of the turbulence. This variation is in general agreement with the high-frequency asymptote of the spectrum form generally assumed for isotropic turbulence. Flow-direction vanes were used to measure the vertical and horizontal components of gust velocity normal to the flight direction. The power spectral densities of the two components are, for practical purposes, equal. The use of vanes is shown to afford a simple, direct method of obtaining the power spectral density of atmospheric turbulence in the relatively high frequency range of airplane response.

Available in PDF, EPUB and Kindle. Book excerpt: The frequency characteristics and statistical properties of the buffet loads measured on the unswept wing and tail of a fighter airplane have been studied in the stall and in the shock regime. The results indicate that the wing loads in buffeting can be treated as the Gaussian response of a simple elastic system. The tail loads appear to represent a more complicated pattern.

This book was released on 1958 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical analysis was made to investigate the performance and acceleration-restriction capabilities of a normal-acceleration command control system in a fighter airplane. Several combinations of pitching velocity and pitching acceleration were investigated as feedback quantities in combination with normal acceleration.

Download or read book Pressure Rise Associated with Shock induced Boundary layer Separation written by Eugene S. Love and published by . This book was released on 1955 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some recent contributions to the problem of shock-induced separation of the boundary layer are examined, and additional analytical and experimental results are presented. The probable ranges of pressure rises and flow deflections associated with separation are indicated. Consideration is given to the effects of Mach number, adverse pressure gradient, and Reynolds number for laminar boundary layers and to the effects of Mach number, Reynolds number, and ratio of sepcific heats for turbulent boundary layers.
