Download or read book Effect of Compressibility on the Hovering Performance of Two 10 foot diameter Helicopter Rotors Tested in the Langley Full scale Tunnel written by Joseph W. Jewel and published by . This book was released on 1958 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: An investigation of the effects of compressibility on the hovering-performance characteristics of two 10-foot-diameter helicopter rotors having solidities of approximately 10 percent has been conducted in the Langley full-scale tunnel. One rotor, having NACA 0012 airfoil sections, a plan-form taper ratio of 3/1, and -8° of twist, was tested to a tip Mach number of 0.95 and a disk loading of 16 pounds per square foot. The other rotor had NACA 64-series airfoil sections, tapering to a 6-cent-thick tip, a plan-form taper ration of 3/1, -16° of twist, and was tested to a tip Mach number of 1.0 and a disk loading of 20 pounds per square foot.

This book was released on 1965 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Force and moment data are presented from wind tunnel tests of two-dimensional symmetrical NACA 63A-Series airfoils of thickness ratios from 9 to 18 percent. The tests were conducted at Mach numbers ranging from M = .30 to M = .94 with Reynolds numbers varying from R = 2.0 X 1,000,000 to R = 9.5 X 1,000,000 and at angles of attack as high as 29 degrees. Comparisons are made, wherever possible, with NACA tests of the same or similar airfoils. The transonic similarity rule is used to evaluate the consistency of the data. (Author).
