Tilt A Whirl PDF Download

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-proprotor 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 introductory part provides a general overview regarding aeroelasticity, followed by the physical principle and the occurrence of whirl flutter in aerospace practice. The next section deals with the experimental research conducted, particularly from the sixties, and the recent developments. The next section discusses the analytical methods such as basic and advanced linear models, and non-linear and CFD based methods. The 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, reports, and papers is provided. This updated and expanded second edition covers new chapters including both analytical and experimental aspects of the subject matter. Provides complex information of turboprop aircraft whirl flutter phenomenon Presents both theoretical and practical (certification related) issues Presents experimental research as well as analytical models (basic and advanced) of matter Includes both early-performed works and recent developments Contains a listing of relevant books and reports
