Innovative Materials for Aircraft Morphing

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...

Multi-body dynamic modelling and flight control for an asymmetric variable sweep morphing UAV

In this paper, the multi-body dynamic model of an asymmetric variable sweep wing morphing UAV is built based on Kane’s method. This model describes the UAV’s transient behaviour during morphing process and the dynamic characteristic of the variable sweep wings. An integrated design of trajectory tracking control via constrained backstepping method is presented then. The idea of aircraft roll co...

Dynamics and Control of Morphing Aircraft

The following work is directed towards an evaluation of aircraft that undergo structural shape change for the purpose of optimized flight and maneuvering control authority. Dy-namical equations are derived for a morphing aircraft based on two primary representations; a general non-rigid model and a multi-rigid-body. A simplified model is then proposed by considering the altering structural port...

A PSOLA based Approach for Voice Morphing

Voice morphing is a name given to procedures which take speech as input from one speaker and attempt to generate speech that sounds like it came from another speaker. One compelling argument for good voice morphing is that it lessens the trouble in creating additional synthetic voices with new characters and styles once an existing voice has been created based on a full-sized corpus. There are ...
