Download or read book Wind tunnel Investigation of an N A C A 23012 Airfoil with Two Arrangements of a Wide chord Slotted Flap written by Thomas Anthony Harris and published by . 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.

Book excerpt: The arrangement of the parts and the installation and control problems of two-stage mechanically driven superchargers for aircraft engines are discussed. Unless an entirely new form of supercharger is developed, there will be a definite need for a two-stage centrifugal supercharger. It is shown that the two-stage mechanically driven supercharger itself is a comparatively simple device; the complications arise from the addition of intercoolers and controls.

This book was released on 1940 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical methods are developed that make it possible for the designer to predict with reasonable accuracy the buckling stress and the maximum-wave amplitude of the sheet in stiffened-panel combinations. The scope of the tests was insufficient to formulate general design criteria but the results are presented as a guide for design and an indication of the type of theoretical and experimental work needed.

This book was released on 1944 with total page 64 pages. Available in PDF, EPUB and Kindle. 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 11 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 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.
