Available in PDF, EPUB and Kindle. Book excerpt: It is emphasized that, if noise reductions are to be obtained or if present noise levels are to be maintained for higher power ratings, future propeller designs should operate at lower tip Mach numbers are currently being used. Single- rather than dual-rotating propellers were found to generate the lowest over-all noise levels for a given number of blades.

Available in PDF, EPUB and Kindle. Book excerpt: The preliminary selection of a propeller on the basis of cruising and take-off performance for application to transport airplanes at flight Mach numbers up to 0.8 can be accomplished by the use of the charts and methods presented. The charts are of sufficient scope to permit a fairly rapid evaluation of the propeller performance for engine power ratings of 1,000 to 10,000 horsepower. The method is presented primarily in the interest of propeller-noise abatement.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Calculations of the rotational-noise and vortex noise loudness levels at distances of 300 and 1000 feet have been made for a large number of propellers in forward flight of 50 to 200 miles per hour and for engine ratings of 100 to 300 horsepower. Propellers of two, four, six, and eight blades, diameters of 6, 8, and 10 feet, and rotational speeds of 1000 to 2000 rpm are considered. Calculated results are presented in chart form for convenience of designers of propellers for applications in which loudness is an important consideration.
