Conceptual Research on a Mono-Biplane Aerodynamics-Driven Morphing Aircraft
The operation of aircrafts with high aspect ratio wings is usually vulnerable to low-standard airports and bad weather. A new concept for a mono-biplane aerodynamics-driven morphing aircraft is proposed.

The Functions of Phasic Wing-Tip Folding on Flapping-Wing Aerodynamics
Insects produce a variety of highly acrobatic maneuvers in flight owing to their ability to achieve various wing-stroke trajectories. Among them, beetles can quickly change their flight velocities and make agile turns.

The Control Efficiency Analysis of Asymmetry Transmutation forFolding Wing Morphing Aircraft
Folding wing morphing aircraft can alter their shape largely which causes the aerodynamic parameters change significantly. A control scheme that using asymmetric morphing as a control input is proposed in this paper to investigate the control efficiency ...

Comparative Aerodynamic Performance Analysis of Camber Morphing and Conventional Airfoils
This paper aims to numerically validate the aerodynamic performance and benefits of variable camber rate morphing wings, by comparing them to conventional ones with plain flaps, when deflection angles vary, assessing their D reduction or L/D improvement.

Graph Matching for Underwater Simultaneous Localization and Mapping Using Multibeam Sonar Imaging
This paper addresses the challenges of underwater Simultaneous Localization and Mapping (SLAM) using multibeam sonar imaging. The widely used Iterative Closest Point (ICP) often falls into local optima due to non-convexity and the lack of features for ...

Comparison of Aerodynamic Characteristics of Morphing and Conventional Wings [PDF]
The present research investigates the advantages of a morphing versus a hinged flap. The morphing wing model is equipped with a morphing trailing edge, while the conventional wing has a hinged flap system.
