WebJan 22, 2006 · As to flatness accuracy, I can suggest a couple things: aluminum backer; 4-5" size, and relatively thick(1") with a thin hard coating of pitch. Have a glass plate of the same size; and very close to flat- maybe1/2-1 fringe concave; and perhaps being plate glass, 3/8-1/2" thick. This is used for pressing the pitch to the shape desired. swat clcr

WebFeb 18, 2024 · C D i = C L π e A. where C L is the lift coefficient, A is aspect ratio and e is the span efficiency factor. For a flat span, e must be smaller or equal to 1, and it's only equal to 1 when the lifting surface has an elliptical lift distribution. When the wing has zero twist, an elliptical planform produces an elliptical lift distribution. WebJun 19, 2014 · A theoretical model for a light source with an elliptical flat-topped beam profile was proposed in , while the intensity distribution of such a source in the far field doesn't have an elliptical flat-topped beam profile. In this paper, we introduce a new random source, named the elliptical MGSM source, which generates a far field with an ... WebAug 30, 2015 · Elliptical, tapered, and rectangular are for subsonic speeds. At these speeds, the major issue is induced drag. The rectangular wing is the easiest to build. The elliptical wing has the lowest induced drag. Tapered is a compromise between the two. There are other factors such as stall behavior that influence choice of planform. swat cipő
