N 456 29 p, 6 figs: Formulas developed on assumption of constant profile-drag coefficient afford extensive insight into influences exerted on flight performances by structure of airplane; designing of practical airplane accomplished on basis of maximum span, while taking into account its contemplated use, wing loading and propeller efficiency. n 457 26 p, 8 figs: Investigation of relations in flight with best coefficient of glide; performance characteristics of airplane follow law independent of shape of airplane, when based on flight conditions at best glide coefficient; aerodynamically best possible or "ideal" airplane produced on this assumption; relations of airfoils. From 1927 Yearbook of Deutsche Versuchsanstalt fuer Luftfahrt.
