Produktbeschreibung

Provides comprehensive coverage of how supersonic commercial aircraft are designed

This must-have guide to conceptual supersonic aircraft design provides a state-of-the art overview of the subject, along with expert analysis and discussion. It examines the challenges of high-speed flight, covers aerodynamic phenomena in supersonic flow and aerodynamic drag in cruising flight, and discusses the advantages and disadvantages of oblique wing aircraft.

Essentials of Supersonic Commercial Aircraft Conceptual Design is intended for members of a team producing an initial design concept of an airliner with the capability of making supersonic cruising flights. It begins with a synopsis of the history of supersonic transport aircraft development and continues with a chapter on the challenges of high-speed flight, which discusses everything from top level requirements and cruise speed requirements to fuel efficiency and cruise altitude. It then covers weight sensitivity; aerodynamic phenomena in supersonic flow; thin wings in two-dimensional flow; flat wings in inviscid supersonic flow; aerodynamic drag in cruising flight, and aerodynamic efficiency of SCV configurations. The book finishes with a chapter that examines oblique wing aircraft.
_ Provides supersonic aircraft designers with everything they need to know about developing current and future high speed commercial jet planes
_ Examines the many challenges of high-speed flight
_ Covers aerodynamic phenomena in supersonic flow and aerodynamic drag in cruising flight
_ Discusses the advantages and disadvantages of oblique wing aircraft

Essentials of Supersonic Commercial Aircraft Conceptual Design is an ideal book for researchers and practitioners in the aerospace industry, as well as for graduate students in aerospace engineering.
