Although the overall appearance of modern airliners has not changed a lot since the introduction of jetliners in the 1950s, their safety, efficiency and environmental friendliness have improved considerably. Main contributors to this have been gas turbine engine technology, advanced materials, computational aerodynamics, advanced structural analysis and on-board systems. Since aircraft design became a highly multidisciplinary activity, the development of multidisciplinary optimization (MDO) has become a popular new discipline. Despite this, the application of MDO during the conceptual design phase is not yet widespread. 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. Objectives are aerodynamic efficiency, mission fuel, empty weight and maximum takeoff weight. Independent design variables studied include design cruise altitude, wing area and span and thrust or power loading. Principal features of integrated concepts such as the blended wing and body and highly non-planar wings are also covered. The quasi-analytical approach enables designers to compare the results of high-fidelity MDO optimization with lower-fidelity methods which need far less computational effort. Another advantage to this approach is that it can provide answers to “what if” questions rapidly and with little computational cost. 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.

"Martin Duberman is a national treasure."—Masha Gessen, The New Yorker    Roger Casement was an internationally renowned figure at the beginning of the 20th century, famous for exposing the widespread atrocities against the indigenous people in King Leopold's Congo and his subsequent exposure—for which he was knighted in 1911—of the brutal conditions of enslaved labor in Peru. An Irish nationalist of profound conviction, he attempted, at the outbreak of World War I, to obtain German support and weapons for an armed rebellion against British rule. Apprehended and convicted of treason in a notorious trial that captured worldwide attention, Casement was sentenced to die on the gallows. A powerful petition drive for the commutation of his sentence was inaugurated by George Bernard Shaw and a host of other influential figures.   A gay man, Casement kept detailed diaries of his sexual escapades, and the British government, upon discovering the diaries, circulated its pages to public figures, thereby crippling what had been a mounting petition for clemency. In 1916, he was hanged. In this gripping reimagining, acclaimed historian Martin Duberman paints a full portrait of the man for the first time. Tracing his evolution from servant of the empire to his work as a humanitarian activist and anti-imperialist, Duberman resurrects and recognizes all facets—from the professional to the personal—of the fantastic life of this pioneer for human rights.
