This book was released on 1948 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was conducted in the Langley 4- by 6-foot tunnel to determine the boundary-layer characteristics of an NACA 0009 airfoil equipped with 0.25- and 0.50-airfoil chord plain sealed flaps. The tests were made to define as thoroughly as possible the characteristics of two of the configurations used in a comprehensive investigation of control surface characteristics and also to provide additional data for comparison with previous boundary-layer analyses. The measured velocity profiles and the boundary-layer parameters determined from them are presented.

Available in PDF, EPUB and Kindle. Book excerpt: Summary: Wind-tunnel tests have been made to determine the aerodynamic section characteristics of an NACA 0009 airfoil with a plain flap having a chord 25 percent of the airfoil chord and a balancing tab having a chord 50 percent of the airfoil chord or 200 percent of the flap chord so linked that the tab would deflect at a given rate with respect to the flap. Three linkage ratios were tested on the model. The tests indicated that the flap and tab could be linked to give hinge-moment balance with flap deflection and with angle of attack and yet have greater lift effectiveness than a plain flap of similar size with a conventional balancing tab having a chord 20 percent of the flap chord linked to give hinge-moment balance with flap deflection only.

This book was released on 1947 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wind tunnel tests have been made to determine the aerodynamic section characteristics of an NACA 0009 airfoil with plain flaps 25 and 50 percent of the airfoil chord. The flaps were tested independently and in combination. Results of the investigation indicated that the larger flap would provide greater lift increments but would lose lift effectiveness at the higher deflect ions and at a lower angle of attack than would the smaller flap. The hinge-moment and lift-effectiveness parameters for each flap indicated good agreement with curves predicting the variation of these parameters with flap chord. Although the effect of sealing the gap was small, it generally increased the lift effectiveness and the lift-curve slope. Theoretical calculations of aerodynamic characteristics made by the use of parameters measured in the present investigation indicated close agreement with calculations made by the use of parameters estimated from pressure-distribution data for a model having similar flaps that were linked to give balance.

Available in PDF, EPUB and Kindle. Book excerpt: Pressure-distribution tests have been made in the NACA 4- by 6-foot vertical tunnel of a plain flap with interchangeable beveled trailing edges on an NACA 0009 airfoil. The flap chord was 30 percent of the airfoil chord and the bevel chords were 15 and 20 percent of the flap chord. The 15-percent bevel was tested with the bevel corner faired with both large and small radii. The purpose of these tests was to supply pressure-distribution data that may be used for structural and aerodynamic design of the horizontal and vertical tail surfaces.

Available in PDF, EPUB and Kindle. Book excerpt: Force-test measurements in two-dimensional flow have been made in the NACA 4- by 6-foot vertical tunnel to determine the aerodynamic effects of changing the alignment of the cover plates on a sealed internally balanced flap. An NACA 0015 airfoil was utilized for the tests. The chord of the straight-contour flap was 30 percent of the airfoil chord and the balance with 50 percent of the flap chord.

Book excerpt: Summary: An investigation was made in the LMAL 7- by 10-foot wind tunnel of an NACA 23021 airfoil with a double slotted flap having a chord 32 percent of the airfoil chord (0.32c) to determine the aerodynamic section characteristics with the flaps deflected at various positions. The effects of moving the fore flap and rear flap as a unit and of deflecting or removing the lower lip of the slot were also determined.

This book was released on 1945 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NACA is conducting an extensive investigation determine the characteristics of various types of flap arrangement suitable for use as control surface and to provide data for design purpose. The investigation, which made in the Langley 4- by 6-foot vertical tunnel, had included test of modifications of flap profile, trailing edge angle, gap size, flap nose shape and balance chord, however most of those tests have been made in two dimensional flow with a flap having a chord 30 percent of the airfoil chord (0.30c). The present tests have extended the investigation of balance chord and flap nose shape, which was reported in reference 1 for a 0.40c flap, to a 0.20c flap. Data on the pressure across the flap nose seal and a method of applying these pressure across the flap nose seal and a method of applying these pressure data in the design of internal balances are presented. Tab data are presented for the plain flap and for a flap with aerodynamic balance.
