Download or read book Theory and Procedure for Determining Loads and Motions in Chine immersed Hydrodynamic Impacts of Prismatic Bodies written by Emanuel Schnitzer and published by . This book was released on 1952 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical method is derived for computing the motions and hydrodynamic loads during water landings of prismatic bodies involving appreciable immersion of the chines. A simplified method of computation covering flat-plate and V-bottom bodies with beam-loading coefficients greater than unity is given as a separate section. Comparisons of theory with experiment are presented as plots of impact lift coefficient and maximum draft-beam ratio against flight-path angle and as time histories of loads and motions. Fair agreement is found to exist for chine-immersed landings for angles of dead rise of 0 degrees and 30 degrees, beam-loading coefficients from 1 to 36.5, flight-path angles from 2 to 90 degrees, and trims from 6 to 45 degrees.

This book was released on 1957 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elevated-temperature compressive-strength test results from room temperature to 600 degrees F and creep test results from 350 degrees F to 500 degrees F are presented for V-groove edge-supported plates of 7075-T6 aluminum alloy. The test data are compared with calculations obtained from procedures for estimating maximum strength from material stress-strain curves and creep-failure stresses from isochronous stress-strain curves. The strength and creep results from this investigation are also compared with similar results from 2024-T3 aluminum-alloy plates.

Download or read book Aerodynamic Loads on a Leading edge Flap and a Leading edge Slat on the NACA 64A010 Airfoil Section written by John A. Kelly and published by . This book was released on 1954 with total page 706 pages. Available in PDF, EPUB and Kindle. Book excerpt: A previous report, NACA TN 3007, gave force and moment data for the NACA 64A010 airfoil section equipped alternately with a flap and a slat at the leading edge, and with a split flap and a double-slotted flap at the trailing edge. The present report presents the chordwise distributions of pressure measured concurrently with the force and moment data of NACA 3007. The pressure data for the leading-edge flap and slat have been converted into coefficients of normal force, chord force, and moment based on the geometry of the leading-edge device.

This book was released on 1956 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretically derived charts showing steady-state and first- and second-harmonic flapping coefficients are presented for helicopter rotors having hinged rectangular blades with a linear twist of 0, -8, and -16 degrees. The charts, showing the rotor flapping coefficients for combinations of inflow ratio and blade pitch angle, are presented for tip-speed ratios ranging from 0.05 to 0.50.
Download or read book Experimental Study of Heat Transfer to Small Cylinders in a Subsonic High temperature Gas Stream written by George E. Glawe and published by . This book was released on 1957 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Nusselt-Reynolds number relation for cylindrical thermocouple wires in crossflow was obtained from the experimental determination of time constants. Tests were conducted in exhaust gas over a temperature range of 2000 to 3400 R, a Mach number range of 0.3 to 0.8, and a static-pressure range from 2/3 to 1-1/3 atmospheres, yielding a Reynolds number range of 450 to 3000. The correlation obtained is Nu=(0.428 plus or minus 0.003) times the square root of Re with average deviations of a single observation of 8.5 percent. This relation is the same as one previously reported for room-temperature conditions.
