Download or read book Experimental Investigation of Flutter of a Propeller with Clark Y Section Operating at Zero Forward Velocity at Positive and Negative Blade-angle Settings written by John E. Baker. This book was released on 1949. Available in PDF, EPUB and Kindle. Book excerpt: The highest flutter speeds were found in the vicinity of the angle of zero aerodynamic moment and the flutter speed increased considerably in this region with decreasing pressure. Over the rest of the pitch range, the flutter speeds were much lower and varied little with pressure.

Book Synopsis Prediction of Downwash Behind Swept-wing Airplanes at Subsonic Speed by : John DeYoung

Download or read book Prediction of Downwash Behind Swept-wing Airplanes at Subsonic Speed written by John DeYoung. This book was released on 1955. Available in PDF, EPUB and Kindle. Book excerpt: A rapid method for estimating the downwash behind swept-wing airplanes is presented. The basic assumption is that of a flat horizontal sheet of vortices trailing behind the wing. The integrations for the downwash are handled in a manner similar to both Multhopp's and Weissinger's approximate integrations in their span-loading calculations. The principal effects of rolling-up of the wake are treated as corrections to the flat-sheet wake. A simple approximate correction for the effect of the fuselage is applied. The agreement with available experimental data taken behind airplane models is good. Computing forms are included together with charts of pertinent functions, so as to enable simple direct application.
