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.
