Book Synopsis Effect of Propeller-axis Angle of Attack on Thrust Distribution Over the Propeller Disk in Relation to Wake-survey Measurement of Thrust by : Robert E. Pendley
Download or read book Effect of Propeller-axis Angle of Attack on Thrust Distribution Over the Propeller Disk in Relation to Wake-survey Measurement of Thrust written by Robert E. Pendley and published by . This book was released on 1945 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were made to investigate the variation of thrust distribution over the propeller disk with angle of pitch of the propeller thrust axis and to determine the disposition and the minimum number of rakes necessary to measure the propeller thrust. The tests were made at a low Mach number for a low and a high blade angle with the propeller operating at three small angles of pitch, and some of the tests were repeated at a higher Mach number. The data obtained show that, for small angles of pitch, large changes occur in the energy distribution in the wake which prohibit the use of a single survey rake for thrust measurement in flight tests and limit the use of a single rake in wind-tunnel tests. Under certain conditions, the energy distribution in the wake took on a symmetrical form and two diametrically opposed survey rakes were shown to be satisfactory for obtaining propeller thrust.

Download or read book A Summary of Meteorological Conditions Associated with Aircraft Icing and a Proposed Method of Selecting Design Criterions for Ice-protection Equipment written by Paul T. Hacker and published by . This book was released on 1951 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on the meteorological parameters pertinent to the aircraft icing problem are so summarized as to give the frequency of occurrence of observed icing situations according to two of the parameters. The summarized data indicate that statistical relations exist between some of the parameters. A method, based upon the collection efficiency of an airfoil and the frequency occurrence of icing situations with various liquid-water contents and mean-effective droplet sizes, is proposed for the selection of design criterions for ice-protection equipment. The method provides a convenient means of calculating the percenteage of icing encounters in which the water collection exceeds the design rate.

This book was released on 1955 with total page 686 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical calculations of the sound-pressure levels by the method of NACA TN 2968 predict accurately, for the 10-foot propeller investigated, the location of and the maximum levels to be expected for the overall noise and the first two propeller harmonics. The calculations do not predict accurately the location of the maximum sound-pressure levels ad the maximum calculated levels are 10 and 13 decibels lower than the msximm messured levels for the third and fourth harmonics, respectively.
