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.

Aeroelastic phenomena arising from the interaction of aerodynamic, elastic and inertia forces, and the loads resulting from flight / ground manoeuvres and gust / turbulence encounters, have a significant influence upon aircraft design. The prediction of aircraft aeroelastic stability, response and loads requires application of a range of interrelated engineering disciplines. This new textbook introduces the foundations of aeroelasticity and loads for the flexible aircraft, providing an understanding of the main concepts involved and relating them to aircraft behaviour and industrial practice. This book includes the use of simplified mathematical models to demonstrate key aeroelastic and loads phenomena including flutter, divergence, control effectiveness and the response and loads resulting from flight / ground manoeuvres and gust / turbulence encounters. It provides an introduction to some up-to-date methodologies for aeroelastics and loads modelling. It lays emphasis on the strong link between aeroelasticity and loads. It also includes provision of MATLAB and SIMULINK programs for the simplified analyses. It offers an overview of typical industrial practice in meeting certification requirements.

This paper presents the results of an analysis of approximately 100,000 hours of V-G data from one type of four-engine civil transport airplane to determine the magnitude and frequency of occurrence of the gust loads and gusts. The data were obtained during routine operations from 1947 to 1954 on five different routes. The normal accelerations for each of the five operations may be expected to exceed the value corresponding to the limit-gust-load-factor increment, on the average, twice (once positive and once negative) within the range of 5,000,000 to 22,300,000 flight miles. A derived gust velocity of 50 feet per second was exceeded twice within the range of 600,000 to 1,900,000 flight miles. The gust loads of the present operations were less than the loads experienced by other four-engine civil transports previously investigated, but the differences are not significant. The present data indicated only small differences due to seasonal effects and different operational utilization.

Two jet-propelled airplanes were flow at different speeds in rough air to investigate the effects of compressibility on applied gust loads at Mach numbers up to 0.68. The results indicated that no compressibility correction to the slope of the lift curve was necessary.
