Although the overall appearance of modern airliners has notchanged a lot since the introduction of jetliners in the 1950s,their safety, efficiency and environmental friendliness haveimproved considerably. Main contributors to this have been gasturbine engine technology, advanced materials, computationalaerodynamics, advanced structural analysis and on-board systems.Since aircraft design became a highly multidisciplinary activity,the development of multidisciplinary optimization (MDO) has becomea popular new discipline. Despite this, the application of MDOduring the conceptual design phase is not yet widespread.
Advanced Aircraft Design: Conceptual Design, Analysis andOptimization of Subsonic Civil Airplanes presents aquasi-analytical optimization approach based on a concise set ofsizing equations. Objectives are aerodynamic efficiency, missionfuel, empty weight and maximum takeoff weight. Independent designvariables studied include design cruise altitude, wing area andspan and thrust or power loading. Principal? features of integratedconcepts such as the blended wing and body and highly non-planarwings are also covered.?
The quasi-analytical approach enables designers to comparethe results of high-fidelity MDO optimization with lower-fidelitymethods which need far less computational effort. Another advantageto 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 andOptimization of Subsonic Civil Airplanes advances understandingof the initial optimization of civil airplanes and is a must-havereference for aerospace engineering students, applied researchers,aircraft design engineers and analysts.ISBN - 9781118568118
