Zalovcik and published by . This book was released on 1950 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is described for calibrating airspeed installations on airplanes at transonic and supersonic speeds in vertical-plane maneuvers in which use is made of measurements of normal and longitudinal accelerations and attitude angle. The required instrumentation is carried within the airplane. The various sources of error are also discussed.

Download or read book A Study of the Transient Behavior of Shock Waves in Transonic Channel Flows written by Robert V. Hess and published by . This book was released on 1952 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accuracy of the result obtained in a fundamental paper by Kantrowitz (NACA TN 1225) that a small short-time lowering of the back pressure in steady, shock-free, transonic diffuser flow causes a stationary or trapped shock to form near the critical sonic channel throat is investigated by considering the contribution of a higher-order term in the short-time calculations which was neglected in Kantrowitz's paper. In this higher approximation to the short-time effects, the shock is no longer stationary or trapped unless it is supported by a negative steady-flow back pressure; the result thus is no long in disagreement with steady-flow solutions for stationary shocks.
Download or read book A Theoretical Investigation of the Aerodynamics of Wing tail Combinations Performing Time dependent Motions at Supersonic Speeds written by John C. Martin and published by . This book was released on 1954 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical investigation is presented of the contribution of horizontal tails to the lift and pitching moment due to angle of attack, a constant rate of pitch, and a constant vertical acceleration. Numerical values of the aerodynamic coefficients associated with these motions are presented for a number of two-dimensional wing-tail combinations, a triangular wing-tail combination, and a number of rectangular-wing - triangular-tail combinations.
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.

Download or read book Stability and Control written by Courtland D. Perkins and published by Elsevier. This book was released on 2014-05-12 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight Testing, Volume II: Stability and Control focuses on the development of adequate flight test techniques for the appraisal of stability and control characteristics and flying qualities of airplanes. This book discusses the flying quality requirements, longitudinal motions, and flight determination of stick-fixed neutral points. The determination of aerodynamic parameters from steady maneuvering, desirable control characteristics in steady flight, and various forms of lateral control surfaces are also elaborated. This publication likewise covers the measurement of maximum lift coefficient, emergency anti-spin devices, and concept of the altitude-Mach number flight envelope. This volume is recommended for design, development or research engineers, test pilots, and instrumentation personnel interested in airplane stability and control.

Download or read book Comparison of Airspeed Calibrations Evaluated by the Accelerometer and Radar Methods written by Lindsay J. Lina and published by . This book was released on 1952 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Airspeed calibration of the pitot-static installation on a jet fighter airplane was made to compare the accelerometer method of determining the static-pressure error with the radar method. The tests included shallow dives up to a Mach number of about 0.80 with pull-ups of about 4, 3, and 2g normal acceleration. The results of the test indicated that, for vertical plane maneuvers, the accelerometer method may be used as an alternate to the radar method.
