Download or read book Experimental Determination of Damping in Pitch of Swept and Delta Wings at Supersonic Mach Numbers written by John A. Moore and published by . This book was released on 1957 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The damping-in-pitch derivative was determined experimentally at Mach numbers of 2.96 and 3.92 for two delta wings having aspect ratios of 2 and 3 and for one sweptback tapered wing having an aspect ratio of 3 by using a free-oscillation technique. The tests were made at Reynolds numbers based on mean aerodynamic chord from 4,000,000 to 12,000,000 for an angle-of-attack range of zero to 10 degrees. The reduced-frequency parameter ranged from 0.006 to 0.022.

Available in PDF, EPUB and Kindle. Book excerpt: Stability and Control of Airplanes and Helicopters deals with aircraft flying qualities that determine the stability and control of airplanes and helicopters. It includes problems based on real aircraft, selected to represent the gamut from simple to complicated, and from conventional utility designs to futuristic research types. Many of these problems involve comparison of theory and experiment to demonstrate their mutual relationship. Comprised of 25 chapters, this book begins with a discussion on the aerodynamics of the component parts related to the lift and moment characteristics of an airplane, including wings and associated accessories; bodies such as fuselages, nacelles, and tip tanks; and control surfaces. The reader is then introduced to some mathematical techniques for linear differential equations; steady flight at different speeds; and stick force and control-free stability. Subsequent chapters focus on flaps and high-lift devices; power and compressibility effects; and the manner in which the aircraft responds to the application of control. Aeroelasticity and longitudinal equations of motion are also examined. This monograph is intended for undergraduate and graduate students taking modern engineering courses.

Boatright and published by . This book was released on 1956 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic loading on delta wings at supersonic speed was studied principally to determine the coupling and nonlinear interference effects between the pressures due to angle of attack and due to thickness. Pressure distributions on four delta wings having leading-edge sweep angles of 53, 60, and 66.6 degrees were measured at Mach numbers of 1.62, 1.93, and 2.41. Three wings had NACA 65A003 sections. The other wing had a flat upper surface and a leading-edge sweep angle of 53 degrees. At Mach numbers of 1.94 and 2.41, some of the results for this wing simulate a wing of zero thickness; the pressure distributions are compared with the pressure distributions of an NACA 65A003 section wing of the same plan form. For this comparison the pressure distributions at zero angle of attack deducted. Appreciable nonlinear interference effects are shown to exist such that the pressure distributions caused by angle of attack are not additive at test angles of attack greater than 5 degrees. These effects are shown to exist for all the NACA 65A003 section wings at all test Mach numbers, and in each case the experimental results are compared with theory.
