In this paper, a morphing carbon fibre composite aerofoil concept with an active trailing edge is proposed. This aerofoil features of camber morphing with multiple degrees of freedom. The shape morphing is enabled by an innovative structure driven by an electrical actuation system that uses linear ultrasonic motors (LUSM) with compliant runners, enabling a full control of multiple degrees of fr...

We introduce a mechanism called “morphing” for introducing structure or randomness into a wide variety of problems. We illustrate the usefulness of morphing by performing several different experimental studies. These studies identify the impact of a “small-world” topology on the cost of coloring graphs, of asymmetry on the cost of finding the optimal TSP tour, and of the dimensionality of space...

A morphing concept for wing drag reduction for a small UAV is presented. The results of a computational assessment of the morphing concept benefits are shown. 14% to 30% drag reduction in different flight stages serve as motivation for the construction of a prototype. Design requirements of the morphing mechanism structure are pointed out and constructive solutions are shown. Feasibility and fu...

A series of demonstrations of synthesized acappella songs based on an auditory morphing using STRAIGHT [5] will be presented. Singing voice data for morphing were extracted from the RWCmusic database of musical instrument sound. Discussions on a new extension of the morphing procedure to deal with vibrato will be introduced based on the statistical analysis of the database and its effect on syn...

In this paper, we present a 3D reconstruction approach of a liver tumour model from a sequence of 2D MR parallel cross-sections, and the integration of this reconstructed 3D model with a mechanical tissue model. The reconstruction algorithm uses shape-based interpolation and extrapolation. While interpolation generates intermediate slices between every pair of adjacent input slices, extrapolati...

In this paper we propose a novel control algorithm for the SmartMesh [1] based on clothes simulation modelled with masses and springs. The SmartMesh is modelled as a tissue or as a blanket, which is attracted by the object that has to be represented, enveloping it. Applying the sampled data (the lengths of the springs) to the actuators of the SmartMesh will result in a deformation of the struct...

A two-dimensional statistical prior model of faces was constructed using the principal components of the shape and texture of a large number of face photographs. Specifically, 94 feature points were manually located on 500 faces selected from the FERET database [1]. The shape variation is then removed by morphing all faces to the mean shape and a second model describing the face texture variati...

ABSTRACT Reported herein is an overview of the research being conducted within the Materials Division at NASA Langley Research Center on the development of smart material technologies for advanced airframe systems. The research is a part of the Aircraft Morphing Program which is a new six-year research program to develop smart components for self-adaptive airframe systems. The fundamental areas...
