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 1947 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dynamometer-stand investigation was conducted to determine the effect of exhaust pressure on the performance of a 12-cylinder liquid-cooled aircraft engine equipped with a conventional exhaust collector. The investigation covered a range of exhaust pressures from about 7 to approximately 62 inches of mercury absolute, engine speeds from 1600 to 3000 rpm, inlet-manifold pressures from 30 to 50 inches of mercury absolute and fuel-air ratios of 0.063, 0.069, 0.085, and 0.100.

Download or read book Wind tunnel Investigation of an N A C A 23021 Airfoil with Two Arrangements of a 40 percent chord Slotted Flap written by Frank Duschik and published by . 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.

This book was released on 1947 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NACA mixture analyzer was developed as a research instrument for the continuous indication of fuel-air ratios of aircraft-engine installations throughout the range of engine operation. It has been evaluated by using it to measure the mixture distribution of a nine-cylinder radial aircraft engine in flight.
