Whirl Flutter of Turboprop Aircraft Structures (eBook, ePUB)

• Format: ePub

Produktbeschreibung

Whirl flutter is the aeroelastic phenomenon caused by the coupling of aircraft propeller aerodynamic forces and the gyroscopic forces of the rotating masses (propeller, gas turbine engine rotor). It may occur on the turboprop, tilt-prop-rotor or rotorcraft aircraft structures. Whirl Flutter of Turboprop Aircraft Structures explores the whirl flutter phenomenon, including theoretical and practical as well as analytical and experimental aspects of the matter. The first introductory part gives a general overview regarding aeroelasticity, followed by the physical principle and the occurrence of whirl flutter in aerospace practice. The next section deals with experiment research including earlier activities performed, particularly from the sixties, as well as recent developments. Subsequent chapters discuss analytical methods such as basic and advanced linear models, and non-linear and CFD based methods. Remaining chapters summarize certification issues including regulation requirements, a description of possible certification approaches and several examples of aircraft certification from the aerospace practice. Finally, a database of relevant books and reports is provided.

Autorenporträt

Jirí Cecrdle started his professional carrier in 1995 at the Czech Aerospace Research Centre (VZLU) in Prague, Czech Republic. He has been the head of the Workgroup of Aeroelasticity there since 2004. He participated in several projects of Czech aircraft development and certification, and he also works as a Compliance Verification Engineer (CVE) and research project evaluator. His spheres of scientific interest include analytical and experimental dynamics and the aeroelasticity of aircraft structures, as well as aeroelastic optimization and model updating. His whirl flutter-related experience includes aircraft certification issues, the development of analytical tools and methods and the development of the whirl flutter aeroelastic wind tunnel demonstrator.
