This book was released on 1948 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains the results of an investigation to determine from linearized theory, which has recently become available, the downwash at supersonic speeds at the tail of the XS-1 airplane and the effect of the downwash on the elevator deflection required for trim. The results are presented in the form of curves showing the variation of downwash angle with angle of attack and elevator deflection required for trim plotted against Mach number. The calculations indicate that increasing up-elevator deflection is required with increasing Mach number (unstable variation) in level flight between Mach numbers of 1.1 and 1.6. A slight reduction in up-elevator deflection occurs between Mach numbers of 1.6 and 2.0. The stabilizer angle has a similar variation, that is, unstable up to a Mach number of about 1.6 and then becoming slightly stable up to a Mach number of 2.0. The reduction of downwash with increasing Mach number is not the main cause of the increase in up-elevator deflection. The main reasons for this trend are that the pitching-moment coefficients due to the wing camber, the wing lift, and the lift of the stabilizer are all in a nose-down direction, and as the Mach number increases, these pitching-moment coefficients apparently decrease less rapidly than the elevator effectiveness.

Download or read book Effect of Lateral Shift of Center of Gravity on Rudder Deflection Required for Trim written by W. H. Phillips and published by . This book was released on 1944 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Tests of a single-engine scout-bomber airplane showed that the rudder deflection required for trim at low speed in the critical wave-off condition may be reduced approximately 10° by a lateral shift of the center of gravity equal to 1.8 percent of the wing span. The reduction in rudder deflection required for trim consists of the rudder deflection required to offset yawing moments from the ailerons and from the component of the weight in the direction of the longitudinal axis and the rudder deflection required to hold the sideslip angle necessary to maintain straight flight. The effect of the lateral loading must be taken into account in tests to determine the adequacy of the rudder for trim. The lateral center-of-gravity location is also important in the service operation of airplanes because, by suitable distribution of the useful load in the wings, the ability of the rudder to trim the airplane in critical power-on conditions may be markedly improved.

This book was released on 2017-12-11 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effect of Lateral Shift of Center of Gravity on Rudder Deflection Required for Trim Two flights were made in a Brewster xsba-l airplane equipped with modified tail surfaces (fig. This airplane was known to have marginal rudder control for trim in some flight conditions and was therefore chosen as representative of the type involved in the problem of providing adequate rudder control in power-oh flight at low speeds. The center of gravity was shifted h.16 inches to the right for the first flight and h.16 inches to the left for the second flight. This shift was accomplished by asymmetric loading of fuel in the wing tanks. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2007-01-20 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight mechanics is the application of Newton's laws to the study of vehicle trajectories (performance), stability, and aerodynamic control. This volume details the derivation of analytical solutions of airplane flight mechanics problems associated with flight in a vertical plane. It covers trajectory analysis, stability, and control. In addition, the volume presents algorithms for calculating lift, drag, pitching moment, and stability derivatives. Throughout, a subsonic business jet is used as an example for the calculations presented in the book.

Available in PDF, EPUB and Kindle. Book excerpt: The study of flight dynamics requires a thorough understanding of the theory of the stability and control of aircraft, an appreciation of flight control systems and a grounding in the theory of automatic control. Flight Dynamics Principles is a student focused text and provides easy access to all three topics in an integrated modern systems context. Written for those coming to the subject for the first time, the book provides a secure foundation from which to move on to more advanced topics such as, non-linear flight dynamics, flight simulation, handling qualities and advanced flight control. - Additional examples to illustrate the application of computational procedures using tools such as MATLAB®, MathCad® and Program CC® - Improved compatibility with, and more expansive coverage of the North American notational style - Expanded coverage of lateral-directional static stability, manoeuvrability, command augmentation and flight in turbulence - An additional coursework study on flight control design for an unmanned air vehicle (UAV)
