NASA-TN-D-8391: Calculations, and comparison with an ideal minimum, of trimmed drag for conventional and canard configurations having various levels of static stability
Abstract: Classical drag equations were used to calculate total and induced drag and ratios of stabilizer lift to wing lift for a variety of conventional and canard configurations. The Flight efficiencies of such configurations that ...
NACA-TR-635: Theoretical stability and control characteristics of wings with various amounts of taper and twist
Abstract: Stability derivatives have been computed for twisted wings of different plan forms that include variations in both the wing taper and the aspect ratio. Taper ratios of 1.0, 0,50, and 0.25 are considered for each of three ...
NACA-TR-1086: Analysis of the effects of wing interference on the tail contributions to the rolling derivatives
Abstract: An analysis of the effects of wing interference on the tail contributions to the rolling stability derivatives of complete airplane configurations is made by calculating the angularity of the air stream at the vertical ...
NASA-TN-D-3845: Rolling stability derivatives of a variable-sweep tactical fighter model at subsonic and transonic speeds
Abstract: Rolling stability derivatives of variable sweep tactical fighter aircraft model at subsonic and transonic speeds
NASA-TM-X-35: Effects of vertical-tail size and a ventral fin on the static lateral and directional stability derivatives of a 0.048-scale model of a horizontal-attitude VTOL airplane at transonic speeds
Abstract: Vertical tail size and ventral fin effects on lateral and directional stability of VTOL AIRCRAFT at transonic speeds
NACA-TR-1284: Theory of wing-body drag at supersonic speeds
Abstract: The relation of Whitcomb's "area rule" to the linear formulas for wave drag at lightly supersonic speeds is discussed. By adopting an approximate relation between the source strength and the geometry of a wing-body ...
NASA-TM-4549: Effect of passive venting on static pressure distributions in cavities at subsonic and transonic speeds
Abstract: The passive venting techniques for shallow cavities that were investigated consisted of (1) porous floors, (2) slot vents at each end of solid floors, (3) slot vents at each end of porous floors, and (4) pipe vents on solid ...
NASA-CR-152141: Prop-fan data support study
Abstract: Updated parametric prop-fan data packages are presented and the rationale used in developing the new prop-fan data is detailed. These data represent Hamilton Standard's projections of prop-fan characteristics for aircraft ...
NASA-CR-2714: Landing gear and cavity noise prediction
Abstract: Prediction of airframe noise radiation from the landing gear and wheel wells of commercial aircraft is examined. Measurements of these components on typical aircraft are presented and potential noise sources identified. ...
NACA-TM-1225: Test Report on Three- and Six-Component Measurements on a Series of Tapered Wings of Small Aspect Ratio (Partial Report: Trapezoidal Wing)
Abstract: The present report, which forms the first of six articles on experiments with airfoils of aspect ratio from 1 to 3 and various planforms, deals with the three- and six-component measurements made on the trapezoidal wing ...
