National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Estimation of Flying Qualities of Piloted Airplanes.

AD483622

Publication Date	1966
Personal Author	Drake, D. E.; Woodcock, R. J.
Page Count	140
Abstract	Methods, ranging from rigorous and complicated to simple and approximate, are presented for estimating flying qualities in accordance with such specifications as MIL-F-8785 (ASG). Aerodynamic and inertial data are assumed to be known. Intended mainly for design use, the report gives enough detail to indicate derivations and conditions for validity. Topics include the static and dynamic, controls-fixed and controls-free aspects of aircraft stability, control, and trim. Although emphasis is on linear analysis, methods are given or indicated for such nonlinear problems as drag, pitch-up, inertial coupling, and spinning. An introduction is given to aeroelastic effects, ways to analyze control tabs, a derivation of the controls-free equations of motion, and an introduction to root locus analysis. (Author)
