Download or read book Wind tunnel Investigation of an NACA 23012 Airfoil with a 0 30 airfoil chord Double Slotted Flap written by Paul E. Purser and published by . 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.

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 1939 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made in the N.A.C.A. 7- by 10-foot wind tunnel of a large-chord N.A.C.A. 23012 airfoil with several arrangements of a 40-percent-chord slotted flap to determine the section aerodynamic characteristics of the airfoil as affected by slot shape, flap location, and flap deflection. The flap positions for maximum lift, the polars for arrangements considered favorable for take-off and climb, and the complete section aerodynamic characteristics for selected optimum arrangements were determined. A discussion is given of the relative merits of the various arrangements. A comparison is made of slotted flaps of different chords on the N.A.C.A. 23012 airfoil.

This book was released on 1941 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been made in the NACA 7- by 10-foot wind tunnel of an NACA 23012 airfoil with a 30-percent-chord Maxwell leading-edge slat and with a slotted and a split flap. The purpose of the investigation was to determine the optimum slot gap of the Maxwell slat for, and the aerodynamic section characteristics of, the airfoil with several deflections of both types of flap. Curves of lift, drag, and pitching-moment characteristics for selected optimum arrangements are presented.

Book excerpt: An investigation was made in the NACA 7- by 10-foot wind tunnel to determine the effect of slot-lip location on the aerodynamic section characteristics of an NACA 23012 airfoil with a 30-percent-chord slotted flap. Tests were made with slot lips located at 90 and 100 percent of the airfoil chord and with two different flap shapes.
