Book Description
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.

Fixed-base and In-flight Simulations of Longitudinal and Lateral-directional Handling Qualities for Piloted Re-entry Vehicles
Author: Edwin A. Kidd
Publisher:
ISBN:
Category : Aeronautics
Languages : en
Pages : 138
Book Description
Longitudinal and lateral directional flying qualities for the re-entry mission are reported. The program utilized primarily a high-fidelity fixed-base ground simulator with evaluations made by three pilots. One of the three pilots also made in-flight evaluations of longitudinal flying qualities in the same vehicle, a threeaxis variable stability airplane flown with a two-axis side controller and conventional rubber pedals. Control sensitivity evaluations were compared to center stick results of earlier work. The longitudinal flying qualities as evaluated both on the ground simulator and in flight are compared and related to earlier investigations. Pilot rating variability, both interpilot and intrapilot, are quantized and discussed for the ground and flight experiments. Performance measures are reported.

Book Description
Because of the 'applied' nature of ergonomics there are many outstanding pieces of work that have never been published in the archival literature. These volumes collect some of those papers that have attained classical status.
