Key features: Presents a new fundamental vision on conceptual airplane design optimization Provides an overview of advanced technologies for propulsion and reducing aerodynamic drag Offers insight into the derivation of design sensitivity information Emphasizes design based on first principles Considers pros and cons of innovative configurations Reconsiders optimum cruise performance at transonic Mach numbers Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes advances understanding of the initial optimization of civil airplanes and is a must-have reference for aerospace engineering students, applied researchers, aircraft design engineers and analysts.
The book describes the state of the art and latest advancements in technologies for various areas of aircraft systems. In particular it covers wide variety of topics in aircraft structures and advanced materials, control systems, electrical systems, inspection and maintenance, avionics and radar and some miscellaneous topics such as green aviation. The authors are leading experts in their fields.
Both the researchers and the students should find the material useful in their work. Louis, Missouri May Author : N. Design methods for advanced aircraft control systems include feedbacks to stabilize relaxed-static- stability vehicles, command and feedback shaping, and gain scheduling.
Extensive use of such designs increases the risk of adverse nonlinear response to pilot control inputs. A common form of this adverse response is pilot-induced oscillation PIO. This paper examines the relationship between nonlinearities in advanced aircraft control systems and PIO.
The results of recent research clearly demonstrate that actuator rate limiting, alone, does not always cause PIO. Other factors. The paper evaluates two other, less thoroughly documented, contributors to PIO - command shaping sensitivity and hysteresis in the flight controls. Inferences about their impact on PIO may be made, but there is not enough data to draw specific conclusions.

This unique book deals with the aeroplane at several levels and aims to simulate its flight performance using computer software. Advanced Aircraft Design: Conceptual Design, Analysis and Optimization of Subsonic Civil Airplanes presents a quasi-analytical optimization approach based on a concise set of sizing equations.
The book describes the state of the art and latest advancements in technologies for various areas of aircraft systems. A common form of this adverse response is pilot-induced oscillation PIO. This paper examines the relationship between nonlinearities in advanced aircraft control systems and PIO. This book provides recommendations for improving general aviation safety by eliminating the after-effects of innovations in general aviation. Pilot-oriented rather than mechanic-oriented, this guide to aircraft systems is designed specifically to help general aviation pilots understand how aircraft systems work so that they can better use them in flight.
