This book was released on 1971 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods presented in five different publications have been used to estimate the low-speed stability derivatives of two unpowered airplane configurations. One configuration had unswept lifting surfaces, the other configuration was the D-558-II swept-wing research airplane. The results of the computations were compared with each other, with existing wind-tunnel data, and with flight-test data for the D-558-II configuration to assess the relative merits of the methods for estimating derivatives. The results of the study indicated that, in general, for low subsonic speeds, no one text appeared consistently better for estimating all derivatives.

Download or read book A Comparison and Evaluation of Two Methods of Extracting Stability Derivatives from Flight Test Data written by Paul W. Kirster and published by . This book was released on 1974 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two methods for extracting stability derivatives from flight data are compared. A modified Newton-Raphson minimization technique and a digital-analog (hybrid) matching technique were used to analyze the same data maneuvers obtained from two aircraft. About 55 maneuvers of an F-111E aircraft were analyzed over a Mach number range of 0.3 to 2.0 and an angle of attack range of 3 to 19 degrees. About 15 maneuvers were analyzed for the X-24A lifting body at Mach numbers of 0.8 and 0.9 and an angle of attack range of 4 to 13 degrees. Stability derivatives were extracted from these maneuvers, and the results from the two techniques along with wind tunnel results were compared. (Modified author abstract).

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.

Donegan and published by . This book was released on 1951 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is presented for obtaining the over-all longitudinal-stability coefficients and frequency response of an aircraft from an analysis of arbitrary maneuvers in which simple instrumentation is used. Although the method presented deals entirely with the aircraft, it is equally applicable to other problems which can be expressed by second-order differential equations.

This book was released on 1952 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of an experimental and theoretical investigation of the effects of large artificial variations of four rotary stability derivatives on the dynamic lateral stability and control of a 45 degree sweptback-wing airplane model are presented. The experimental results are presented mainly in the form of flight ratings for stability, control, and general flight behavior. Calculations of period and damping and of the response of rolling and yawing disturbances are also presented.

This book was released on 1971 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: For application to a new technique of predicting aerodynamic loads, a study was made to determine the accuracy of dynamic stability derivatives as predicted for the North American Navion by several different sources. Using the results of flight tests as the norm, estimates from wind tunnel tests and several texts were compared and found to be accurate to within the order of 20% with a few exceptions. It is believed that the results of the study would be typical of single engine light aircraft with straight wing and tail, propeller propulsion, and low power effects. (Author).

Download or read book Determination of Lateral Stability Characteristics from Free flight Model Tests with Experimental Results on the Effects of Wing Vertical Position and Dihedral at Transonic Speeds written by Clarence L. Gillis and published by . This book was released on 1960 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A test and analysis method is presented for determining airplane lateral stability characteristics, including aerodynamic derivatives, from flight tests of scale models. The method of analysis utilizes the rotating time-vector concept and also a quasi-static approach. Data are presented at transonic speeds for three swept-wing rocket-propelled models differing only in vertical position and dihedral of the wing. The method proved to be adequate for delineating the major effects of the geometric variations on the aerodynamic lateral stability derivatives. The effects of Reynolds number on the linearity of the static stability data for an unswept wing configuration are illustrated.
