Structural and Aerodynamic Models in the Nonlinear Flight Dynamics of Very Flexible Aircraft
An evaluation of aerodynamic and structural models is carried out for their application to flight dynamics of low-speed aircraft with very-flexible high-aspect-ratio wings. The structural dynamic approaches include displacement-based, strain-based, and intrinsic (first-order) geometrically-nonlinear composite beam models, while thin-strip and vortexlattice methods are considered for the unstead...
متن کاملStructural and Aerodynamic Models in Nonlinear Flight Dynamics of Very Flexible Aircraft
An evaluation of computational models is carried out for flight dynamics simulations on low-speed aircraft with very-flexible high-aspect ratio wings. Structural dynamic models include displacement-based, strain-based, and intrinsic (first-order) geometrically-nonlinear composite beams, while thin-strip and vortex lattice methods are considered for the unsteady aerodynamics. It is first shown t...
متن کاملNonlinear Aeroelasticity of a Very Flexible Blended-Wing-Body Aircraft
This paper presents a study on the coupled aeroelastic/flight dynamic stability and gust response of a blendedwing-body aircraft that derives from the U.S. Air Force’s High Lift-Over-Drag Active (HiLDA) wing experimental model. An effective method is used to model very flexible blended-wing-body vehicles based on a low-order aeroelastic formulation that is capable of capturing the important str...
متن کاملGeometrically Nonlinear Aeroelastic Scaling for Very Flexible Aircraft
High-aspect-ratio wings present in very flexible aircraft can undergo large deformations, which results in significant changes in natural frequencies as well as in static and dynamic aeroelastic response. This geometric nonlinear behavior becomes an integral part of any aeroelastic analysis to be conducted in such class of vehicles. Aeroelastic scaling is an important way to study the aeroelast...
متن کاملModeling for Control of Very Flexible Aircraft
The first investigations into the dynamics of a highly flexible aircraft came from the Daedalus Project, initiated in 1984. 3 The goal of this project was to push the limits of human powered flight while promoting engineering, science and education. Prior to the Daedalus Project the longest distance traveled by a human powered plane was 23 miles, a record set in 1979 with a flight across the En...
