Flight Physics pp Cite as. The term flying qualities denotes primarily the combination of stability and control properties which have an important influence on the ease and precision with which a pilot can maintain a state of equilibrium and execute manoeuvres, and thereby on flight safety and operational effectiveness. The term stability characterizes the motion of an aeroplane when returning to its equilibrium position after it has been disturbed from it without the pilot taking action. Aircraft control describes the response to actions taken by a pilot to induce and maintain a state of equilibrium or to execute manoeuvres. For military aircraft, the definition of flying qualities is broadened with an assessment of the precision and effectiveness with which tasks can be performed. Qualities like agility and targeting precision are closely associated with handling qualities , a term which denotes the short-term dynamic response of an aeroplane as a reaction to control.
Stability derivatives , and also control derivatives , are measures of how particular forces and moments on an aircraft change as other parameters related to stability change parameters such as airspeed , altitude , angle of attack , etc. For a defined "trim" flight condition, changes and oscillations occur in these parameters. Equations of motion are used to analyze these changes and oscillations. Stability and control derivatives are used to linearize simplify these equations of motion so the stability of the vehicle can be more readily analyzed. Stability and control derivatives change as flight conditions change. The collection of stability and control derivatives as they change over a range of flight conditions is called an aero model. Aero models are used in engineering flight simulators to analyze stability, and in real-time flight simulators for training and entertainment.

The purpose of this paper is to develop a new approach for rapid computation of subsonic and low-transonic rotary derivatives with the available steady solutions obtained by Euler computational fluid dynamics CFD codes. The approach is achieved by the perturbation on the steady-state pressure of Euler CFD codes. The resulting perturbation relation is established at a reference Mach number between rotary derivatives and normal velocity on surface due to angular velocity. The solution of the reference Mach number is generated technically by Prandtl—Glauert compressibility correction based on any Mach number of interest under the assumption of simple strip theory.

Aircraft Dynamic Stability and Response deals with the fundamentals of dynamic stability in aircraft. Topics covered include flight dynamics, equations of motion, and lateral and longitudinal aerodynamic derivatives. Basic lateral and longitudinal motions are also considered. A non-dimensional system of notation is used, and problems are included at the end of chapters. This book is comprised of 13 chapters and begins with an introduction to aircraft static stability and maneuverability, with emphasis on the theoretical basis of flight dynamics and the technical terms used. The physical background for the estimation of aerodynamic derivatives is discussed.
- Стратмор остановился и повернулся к Сьюзан. - Он сказал, что на кольце были выгравированы какие-то буквы. - Буквы. - Да, если верить ему - не английские. - Стратмор приподнял брови, точно ждал объяснений. - Японские иероглифы. Стратмор покачал головой.
