This book was released on 1940 with total page 40 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 15-percent-chord and a 25-percent-chord balanced split flap of the Clark Y profile. The investigation was made to determine the aerodynamic section characteristics of the airfoil as affected by the size, nose location, and deflection of the flap. Complete aerodynamic section characteristics were determined for several nose locations of each flap and are presented for four typical locations for each flap. A comparison of the drag and lift characteristics is made with two other medium-chord flaps previously investigated.

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 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the 7- by 10-foot wind tunnel of an NACA 23102 airfoil equipped with a Handley Page slate and a slotted and a split flap. The purpose of the investigation was to determine the aerodynamic section characteristics of this airfoil with and without flaps, as affected by the location of the Handley Page slat. A range of slat-nose locations was investigated both with and without flaps at a constant slat gap, and the effect of slat gap was investigated for the slotted flap deflected 40 degrees. The slat position for maximum lift, polars for slotted and split flaps for the most favorable slat arrangements for maximum lift, and complete section data for the most favorable slat arrangements are included. Contours of slat-nose location are given for maximum lift coefficient, for angle of attack for maximum lift coefficient, and for drag and pitching moments at selected lift coefficients.

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.

This book was released on 1941 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerodynamic characteristics of a rectangular NACA 23012 airfoil with single and double perforated split flaps have been determined in the NACA 7- by 10-foot wind tunnel. A large range of flap spans and deflections and a large range of spanwise and chordwise locations of the flaps were investigated. Dynamic pressure surveys were made behind the wing at the approximate location of the tail, in order to determine the extent and location of the wake for each flap arrangement. Tests were also made with a full-span plain flap to determine the effect of the various split-flap arrangements on aileron control.
