This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The induced drag is one of the most important sources of aerodynamic drag in an aircraft, and reducing it could mean saving thousands of dollars in fuel per plane and year. For this reason, since the 1970s oil crisis, agencies like NASA and airplane manufacturers have been developing wing-tip devices with the objective to reduce the induced drag. This work presents a discussion of the effects that the most common used wing-tip devices have on an airplane's aerodynamic and structural performance. It is also discussed the effects of a non-planar wing design, which is a relatively new concept design that has not been used in commercial aircrafts yet. The analysis in this work are based on inviscid flow simulations. Since induced drag only depends on the lift distribution over the wing, it can be approximated with inviscid methods and the boundary layer can be neglected.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
