Gust Loads on Aircraft: Concepts and Applications (Aiaa Education Series)

this Book Provides An Authoritative And Practical Presentation Of The Determination Of Gust Loads On Airplanes, Especially Continuous Turbulence Gust Loads. The Text Emphasizes The Basic Concepts Involved In Gust Load Determination And Enriches The Material With Discussion Of Important Relationships, Definitions Of Terminology And Nomenclature, Historical Perspective, And Explanations Of Relevant Calculations. Coverage Begins With Discrete-gust Idealization Of The Gust Structure And Moves To Continuous-turbulence Gust Loads. Also Considered Are Loads Combination And Design Criteria, Gust-response Equations Of Motion, Spanwise Variation Of Vertical Gust Velocity, Nonlinear Systems, And Analysis Of Gust-response Flight-test Data. booknews this Volume Was Sponsored By The Lockheed Aeronautical Systems Company And Was Originally Published As A Lockheed Report. The Author Begins With The Older Concept Of Discrete-gust Idealization Of The Gust Structure, Including The Subject Of Static And Dynamic Loads, And Then Moves On To The More Modern Power-spectral, Or Continuous-turbulence, Concepts And Methods.
