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.

Book excerpt: An investigation was made in the N.A.C.A. 7- by 10-foot wind tunnel of a N.A.C.A. 23021 airfoil with two arrangements of a 40-percent-chord slotted flap. The effect of slot shape, flap position, and flap deflection on the section aerodynamic characteristics was determined. The envelope polars and the section aerodynamic characteristics are given and are compared with those of an N.A.C.A. 23021 airfoil with a 25.66-percent-chord slotted flap and of an N.A.C.A. 23012 airfoil with a 40-percent-chord slotted flap. Plotted contours of flap-nose positions for maximum lift and minimum drag were used for selecting optimum flap paths.

This book was released on 1941 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made in the NACA 7- by 10-foot wind tunnel of a large-chord NACA 23021 airfoil with a 15-percent-chord and a 25-percent-chord balanced split flap of Clark Y profile, to determine the aerodynamic section characteristics of the airfoil-flap combinations as affected by the size, nose location, and deflection of the flaps. Section lift, drag, and pitching-moment characteristics are presented in the form of contours of flap nose location for given values of the lift, drag, and pitching-moment coefficients and complete aerodynamic section characteristics are presented for four representative locations of each flap. The two balanced split flaps are compared with a slotted-flap arrangement in a previous investigation.

This book was released on 1942 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests to determine the effect of flap position and deflection on the aerodynamic characteristics of an NACA 23012 airfoil with a double slotted flap having a chord 30 percent of the airfoil chord (0.30c) were conducted in the LMAL 7- by 10-foot tunnel. In addition, a few tests were made to determine the aerodynamic section characteristics as affected by the size and shape of the fore flap, by movement of the fore flap and rear flap as a unit, and by variation in the airfoil lower lip. Contours of rear-flap-nose position for various values of maximum section lift coefficient, section profile-drag coefficient, and section pitching-moment coefficient are presented at three selected fore-flap positions for various rear-flap deflections. The complete aerodynamic section characteristics are given at the three selected fore-flap positions for the optimum-lift and optimum-drag positions of the rear flap at several deflections.

This book was released on 1940 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the N.A.C.A. 7- by 10-foot wind tunnel of a large-chord N.A.C.A. 23030 airfoil with a 40- and a 25.66-percent-chord slotted flap to determine the section aerodynamic characteristics of the airfoil as affected by flap chord, slot shape, flap position, and flap deflections. The flap positions for maximum lift, the positions for minimum drag at moderate and high lift coefficients, and the complete section aerodynamic characteristics of selected optimum arrangements are given. Envelope polars of various flap arrangements are included. The relative merits of slotted flaps of different chords on the N.A.C.A. 23030 airfoil are discussed, and a comparison is made of each flap size with a corresponding flap size on the N.A.C.A. 23021 and 23012 airfoils.

Book excerpt: Summary: An investigation was carried out in the NACA two-dimensional low-turbulence pressure tunnel of the NACA 66(215)-216, 66,1-212, and 651-212 airfoil sections equipped with split flaps having chords 20 percent of the airfoil chord. The purpose was to determine the maximum-lift characteristics of these low-drag airfoil sections with split flaps. All the present tests were made at a Reynolds number of approximately 6 x 106 and a Mach number of about 0.15.
