This book was released on 1948 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight tests have been conducted to determine the lateral and directional stability and control characteristics of an airplane on which the wing panels are swept back 35 deg. For these tests, the wings are equipped with slots extending from 40 to 80 percent of the span of the sweptback wing panels measured from the inboard end. Wind-tunnel tests were made. of a model of the airplane and wherever possible the flight and wind-tunnel data have been compared.

This book was released on 1948 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight measurement were made at low speeds to determine the static longitudinal stability, stability, and lift characteristics of an airplane having a wing swept back 35c at the quarter-chord line. The airplane was tested without slots on the wing and with slots%Us which extended from 8O percent to 80 percent of the semispan of the sweptback-wing panels measured from the inboard end. The longitudinal stability of the airplane with the flaps up was high with or without slots throughout the speed range tested. With the flaps down the longitudinal stability was high at moderate speeds, but near the stall the stability of the airplane was neutral or slightly negative. The pilot had no serious objections to the neutral longitudinal stability present near the stall because he could easily control pitching with the elevator. The slots increased the stalling speed and therefore reduced the speed range over which the neutral or slightly negative stability was present.

Download or read book Flight Stability and Automatic Control written by Robert C. Nelson and published by WCB/McGraw-Hill. This book was released on 1998 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Flight Stability and Automatic Control presents an organized introduction to the useful and relevant topics necessary for a flight stability and controls course. Not only is this text presented at the appropriate mathematical level, it also features standard terminology and nomenclature, along with expanded coverage of classical control theory, autopilot designs, and modern control theory. Through the use of extensive examples, problems, and historical notes, author Robert Nelson develops a concise and vital text for aircraft flight stability and control or flight dynamics courses.

Bird and published by . This book was released on 1950 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimentally determined lateral-stability derivatives of a swept-wing airplane are presented to show effects of slots, flaps, propeller, and ventral fins and are sued in calculations of a number of lateral disturbed motions. The calculated motions are compared with those obtained in flight tests to determine the applicability of the experimental stability derivatives . The effects of nonlinearity of some of the aerodynamic forces with sideslip are shown by a few supplemental calculations.

Book excerpt: Introduction: Directional control difficulties had been experienced in P-40 series airplanes in dive demonstrations and inadvertent entry into spins in service operations. At the request of the Army Air Forces, Materiel Command, quantitative measurements of rudder trim force change with speed and power, rudder force reversals in sideslips, and rudder positions in sideslips and straight flight of a P-40E airplane were made. Quantitative measurements of these items were also made on three other vertical tail arrangements supplied by the Curtiss-Wright Corporation. The results of these measurements are presented in this report.
