Morphing wings of aircraft [PDF]

Práce a štúdie, 2022
Goal of the paper is to describe use of morphing wings on aircraft and their possible use to increase aerodynamic efficiency of aircraft. Paper is divided into two parts. First part focuses on design and material requirements of morphing wings as well as describes some of studied concepts.

A Review of Morphing Aircraft [PDF]

Journal of Intelligent Material Systems and Structures, 2011
Aircraft wings are a compromise that allows the aircraft to fly at a range of flight conditions, but the performance at each condition is sub-optimal. The ability of a wing surface to change its geometry during flight has interested researchers and designers over the years as this reduces the design compromises required.

Intelligence for Morphing Aircraft [PDF]

, 2022
Adding intelligence to uncrewed aerial vehicle (UAV) design to improve performance in a variety of dynamic environments offers benefits to many civilian and military mission objectives. Urban areas with tall buildings and vast street systems create drastic changes in the flight environment that are challenging for autonomous flight vehicles to overcome.

Morphing wings for unmanned aircraft

Smart Materials Bulletin, 2001
Abstract Here a computational model is presented which predicts the force, stroke and energy needed to overcome aerodynamic loads encountered by morphing wings, to perform aircraft manoeuvres. The aerodynamic load algorithms have been verified against more time-expensive codes.

Intelligent Control of a Morphing Aircraft

48th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2007
A morphing aircraft is able to drastically alter its planform to optimize performance at very dissimilar flight conditions. Despite significant strides to develop wing structure and actuation systems, much work remains to effectively control both the morphing wing as well as the entire morphing aircraft.

Modeling of Dynamic Loading of Morphing Wing Aircraft

AIAA Atmospheric Flight Mechanics Conference, 2010
The simulation of dynamic loads and required power is essential for the design of any morphing wing aircraft, since it ultimately determines the feasibility of a given morphing configuration. In this paper a methodology suitable for numerical calculation of the dynamic loads for a morphing-wing aircraft is presented.

On the effectiveness of active aeroelastic structures for morphing aircraft

The Aeronautical Journal, 2013
AbstractThis note assesses the benefits of active aeroelastic structures (AAS) in enhancing flight performance and control authority. A representative AAS concept, whose torsional stiffness and shear centre position can be altered depending on the instantaneous flight condition, is employed in the wing of a medium altitude long endurance (MALE) UAV.
