This book was released on 1970 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project concerns a subsonic investigation of a new type of flutter phenomenon, not previously critical from a design standpoint, involving elastic modes of the wing, fuselage, and stabilizer combination and also involving aerodynamic interference between the wing and horizontal tail. The effort, consisting of design of a flutter model, vibration and subsonic wind tunnel tests, and flutter analyses, was conducted to determine important controlling flutter parameters, to evaluate the accuracy of analyses for predicting the phenomenon, to establish flutter trends and to define flutter prevention design criteria which could be used in the early design stage to avoid the problem. Some of the important features that were determined are increasing wing sweep can lead to lower flutter speeds; wing bending to fuselage torsion frequency ratios were defined which provide the mechanical coupling essential to produce the phenomenon and minimum flutter speeds as a function of wing sweep angle; vertical separation or dihedral angle can be very influential and beneficial and is more important than longitudinal separation, the effects of which were found to be small to moderate; the effects of compressibility have been shown to be detrimental and decrease the flutter speed, and conclusive proof that the interference aerodynamics between the wind and tail, and particularly, the downwash shed from the wing, is an important and detrimental feature to the phenomenon.

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 and published by . This book was released on 1955 with total page 688 pages. 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.

This book was released on 1956 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lateral flow characteristics in the region of a vertical tail have been investigated experimentally and theoretically at low subsonic speeds. The effects of changes in wing-body geometry such as nose position and shape, fuselage cross-sectional shape, and wing vertical position are described. The theoretical model which approximates the separated flow phenomena by a simple cylinder-vortex flow is described in an appendix.
