Download or read book A Method of Calculating a Stability Boundary that Defines a Region of Satisfactory Period damping Relationship of the Oscillatory Mode of Motion written by Leonard Sternfield and published by . This book was released on 1949 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method has been derived by which a boundary can be obtained that defines a region in which there exists a satisfactory relationship between the period and damping of the lateral oscillatory mode of motion, according to any given criterion for this relationship. In addition, a method is discussed by which curves representing a constant rate of spiral divergence may be constructed. The methods presented are applicable as well to the analysis of longitudinal stability. A method for evaluating the roots of a quartic equation is also discussed.

Download or read book Investigation of NACA 64 2 432 and 64 3 440 Airfoil Sections with Boundary layer Control and an Analytical Study of Their Possible Applications written by Elmer A. Horton and published by . This book was released on 1951 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to determine the effect of boundary-layer control by means of suction through a slot of 0.60c on the pressure distribution, lift, and drag characteristics of the NACA 64,2-432 and 64,3-440 airfoil sections. The effect on the section aerodynamic characteristics of boundary-layer control by means of a slot at 0.50c and by means of area suction from 0.55c to 0.71c was also investigated for the NACA 64,3-440 airfoil. An analysis was made to show the effect of such thick airfoil sections and boundary-layer control on the lift-drag ratio of a wing. The section data presented and employed in the analysis to the leading edges of the models. This roughness was probably more severe than that likely to be encountered on practical aircraft under normal operating conditions; therefore, the drag coefficients measured bot with and without boundary layer control may be somewhat high as compared with practical flight values.
