Gust Loads on Aircraft


Book Description




Gust Loads on Aircraft


Book Description

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.




Introduction to Aircraft Aeroelasticity and Loads


Book Description

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.




Active Spanwise Lift Control


Book Description

Presents a novel approach to tackle the gust alleviation problem. The authors address the spanwise behaviour of aerodynamic loads, as this is what should be primarily controlled. Because the gust loads are mainly caused by disturbances in the spanwise lift, the aim is at controlling the shape of the lift distribution profile along the span.




Introduction to Aircraft Flight Mechanics


Book Description

Based on a 15-year successful approach to teaching aircraft flight mechanics at the US Air Force Academy, this text explains the concepts and derivations of equations for aircraft flight mechanics. It covers aircraft performance, static stability, aircraft dynamics stability and feedback control.
