Available in PDF, EPUB and Kindle. Book excerpt: Results of a combined analytical/flight test evaluation to investigate the effects of short period zero (T theta 2) on aircraft handling qualities are presented. Two optimal pilot models were used for the analytical portion. 1/T theta 2 was varied from 0.1 to 10 for each 4 different short period configurations. Flight testing was accomplished in the variable stability NT-33A aircraft, over a range of 1/T theta 2 values at one short period configuration. A pitch tracking task was used to generate RMS pitch errors for both the analytical and flight test phase. Cooper-Harper ratings were also collected during the flight test. Analytical results showed similar trends for all short period configurations, with pilot tracking task performance degrading at low 1/T theta 2 values. The bandwidth criterion was of limited use in predicting handling qualities levels based on T theta 2 variations alone. DC gain variations produced minimal differences in pilot performance. Overall evaluation results indicate that T theta 2 placement is an important factor in short period handling qualities and should be included in future revisions to MIL-F-8785C.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 1962 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The systems-analysis theory of handling qualities (which describes the pilot's adaptive behavior in closed-loop operation by servo techniques, and relates his opinion-ratings to his adapted characteristics and the system performance) is used to reveal some important parameters associated with the numerator terms in the airframe longitudinal transfer function. The predictions are verified by five experienced test pilots operating in a fixed-base aircraft simulator. Four possible numerator effects on handling qualities are analyzed theoretically: short-period lead effect on pitch attitude tracking, static-to-short-period gain effects on attitude tracking, short-period lead effects on the control of short-period divergence, and numerator frequency and damping effects on altitude tracking. The results are correlated with other test work, and the implications of these results on future handling qualities research and specifications are discussed.

This book was released on 1965 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of a flight research program to evaluate the effects of certain lateral-directional handling qualities are reported and discussed. The evaluation program was designed to assess the acceptability of variations in Dutch roll dynamics and aileron-yaw coupling for the low speed landing approach task. The effects of a reduction in static directional stability on the high Mach number cruise task were also evaluated. A variable stability T-33 was used for conducting these evaluations. Thirty-three different sets of low speed, and fifteen different sets of high speed lateral-directional handling qualities were evaluated by an experimental test pilot. The evaluation pilot comments and a numerical rating were given for each configuration as to its suitability for the mission or task involved. Identification of the stability parameters from in-flight records was made using airplane rudder doublet responses and the Equations-of-motion Technique. An analysis was made of the pilot ratings and pilot comments, and these in turn were correlated with the lateral-directional stability parameters measured. (Author).
