Optimum wing shape for an active flexible wing
36th Structures, Structural Dynamics and Materials Conference, 1995A study was conducted to investigate the potential weight savings that can be achieved by using active flexible wing technology. In addition, the optimum wing shape to which to apply this technology was also identified. The study was conducted using a combination of the Taguchi method and the ASTRIGS and ASTROS codes.

An Online Reinforcement Learning Wing-Tracking Mechanism for Flexible Wing Aircraft
2019 IEEE International Symposium on Robotic and Sensors Environments (ROSE), 2019Flexible wing aircraft are gaining an increasing interest due to their salient features, such as inexpensive market price, low-cost operation, in-flight robustness, multi-purpose use, and their ability to operate with very little infrastructure. The continuous variations in the aerodynamics of the wing and additionally the kinematic and dynamic ...

Optimization Process for Configuration of Flexible Joined-Wing
10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004An optimized configuration design utilizing both structural and aerodynamic analyses of a flexible joined-wing configuration is presented in this paper. The joined-wing aircraft concept fulfills a proposed long-endurance surveillance mission and incorporates a load-bearing antenna structure embedded in the wing skin.

A method for enhancement of the rolling maneuver of a flexible wing
37th Structure, Structural Dynamics and Materials Conference, 1996A technique for augmenting the aileron to increase the roll rates of a high-performance aircraft at high dynamic pressures for enhancement of the rolling maneuver is examined. Antisymmetric twist and camber distribution on a realistic flexible wing is determined to counteract the detrimental twisting moment of the aileron rotation to achieve recovery ...

Flexible flapping wings with self-organized microwrinkles
Bioinspiration & Biomimetics, 2015Bio-inspired flapping wings with a wrinkled wing membrane were designed and fabricated. The wings consist of carbon fibre-reinforced plastic frames and a polymer film with microscale wrinkles inspired by bird feathers and the corrugations of insect wings.

Wing flexibility improves bumblebee flight stability
Journal of Experimental Biology, 2016Insect wings do not contain intrinsic musculature to change shape, but rather bend and twist passively during flight. Some insect wings feature flexible joints along their veins that contain patches of resilin, a rubber-like protein. Bumblebee wings exhibit a central resilin joint (1m-cu) that has previously been shown to improve vertical force ...

Effect of Spanwise Flexibility on Flapping Wing Propulsion
36th AIAA Fluid Dynamics Conference and Exhibit, 2006A water tunnel study of the effect of spanwise flexibility on the thrust, lift and propulsive efficiency of a rectangular wing oscillating in pure heave has been performed. The thrust and lift forces were measured with a force balance, and the flow field was measured with a Particle Image Velocimetry system. Introducing a degree of spanwise flexibility

Energy Extraction by Flexible Flapping Twin Wing
Volume 8: Ocean Renewable Energy, 2013The present study aims to investigate how the flexure of oscillating wings affect their hydrodynamic performance and tidal energy extraction efficiency based on their flapping motions. To achieve this goal, a numerical simulation is carried out by solving a low Mach number compressible Navier-Stokes equation for a parallel arranged twin wing system ...

Trajectory control of a very flexible flying wing
2017 American Control Conference (ACC), 2017This paper investigates the trajectory control of a very flexible flying wing model, which is derived from geometrically-nonlinear beam theory using intrinsic structural description in [1]. This model is coupled with structural dynamics, aeroelastic dynamics and flight dynamics.
