Download or read book Tank Tests to Determine the Effect of Varying Design Parameters of Planing tail Hulls written by John R. Dawson and published by . This book was released on 1946 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted in Langley tank no. 2 on models of an unconventional flying-boat hull called a planing-tail hull to determine the effects on resistance of varying a number of afterbody parameters. The effects of varying length, width, and plan-form taper of the afterbody are presented. Tests were made with afterbodies of two widths, two lengths, and two tapers. In the tests the depth of step and the angle of afterbody keel were held constant.

Book excerpt: The second part of a series of tests made in Langley tank no. 2 to determine the effect of varying design parameters of planing-tail hulls is presented. Results are given to show the effects on resistance characteristics of varying angle of afterbody keel, depth of step, and length of afterbody chine. The effect of varying the gross load is shown for one configuration. The resistance characteristics of planing-tail hulls are compared withthose of a conventional flying-boat hull. The forces on the forebody and afterbody of one configuration are compared with the forces on a conventional hull.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to determine the aerodynamic characteristics of three planing-tail flying-boat hulls which differed only in the amount of step fairing. The hulls were derived by altering the step and afterbody of a conventional flying-boat hull having a transverse step.

Download or read book Investigation of the Air compression Process During Drop Tests of an Oleo pneumatic Landing Gear written by James H. Walls and published by . This book was released on 1951 with total page 788 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief study has been made to evaluate the importance of the type of air-compression process on the loads produced on an oleo-pneumatic landing gear during impact and to determine the type of air compression process actually obtained during drop tests. A simplified analysis to determine the effect which different air-compression processes might have indicates that the value of the air-compression exponent should have relatively little effect on the landing-gear loads throughout most of the impact. The analysis of experimental data obtained in these tests shows that the polytropic exponent ranged from 1.01 to 1.10 for the condtions tested. The general trend of the data appears relatively independent of vertical contact velocity.

This book was released on 1947 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: An approximate method for determining the convective cooling requirement in the laminar-boundary-layer region of a body of revolution in high-speed flight was developed and applied to an example body. The cooling requirement for the example body was determined as a function of Mach number, altitude, size, and a surface-temperature parameter. The maximum value of Mach number considered was 3.0 and the altitudes considered were those within the lower constant-temperature region of the atmosphere (40,000 to 120,000 ft). The extent of the laminar boundary layer was determined approximately at each condition as a function of the variables considered.
