Hoblit F.M. Gust Loads on Aircraft: Concepts and Applications

AIAA, Washington, 1988, 306 p. — ISBN: 0930403452, 9780930403454.American Institute of Aeronautics and Astronautics. AIAA EDducation Series, Volume 3797This 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.Gust Loads Fundamentals
