Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-point inspects large aircraft wing skin areas. In addition it is too ....etc

This Project is very simple and when completed, causes a light-emitting diode (LED) to flash or pulse alternately on and off at a very slow rate, that is, at a low frequency. It could be used as a dummy car alarm indicator. You sometimes see these tiny pulsating lights in expensive cars protected by sophisticated car security systems, warning you that the car alarm is armed and ready.
For this design, the LED flashes on for a brief period and stays off for a relatively longer period. Because additional current is consumed from the battery eve ....etc

A variable-speed controller, for an existing 225 kW fixed-speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind speeds. This algorithm is based on direct activ ....etc

Abstract
Mounting engines on the wing causes complex wing
flutter characteristics. The location of the engine mass
and the stiffness of the pylon relative to the wing are
important in preventing hazardous wing flutter. In
addition, if the nacelles are installed over the wing,
aerodynamic interference between the wing and the
nacelle may cause unfavorable flutter characteristics, in
particular, at transonic speeds. The flutter
characteristics of an over-the-wing engine mount
configuration obtained from theoretical analyses and
....etc

Swarming Micro Air Vehicle Networks SMAVNET
Abstract
The SMAVNET project aims at developing swarms of flying robots that can be deployed in disaster areas to rapidly create communication networks for rescuers. Flying robots are interesting for such applications because they are fast, can easily overcome difficult terrain, and benefit from line-of-sight communication. This is inspired from biology to implement controllers based on ant-foraging or resulting from artifi ....etc

ABSTRACT
Micro air-vehicle is a small flight vehicle that uses a lift-generating mechanism that is different from the mechanism used for large aircrafts. In micro air- vehicles, one of the methods for creating lift is a special flapping mechanism, which consists of translation and rotational motions of wings. This is adopted from one species of insect Encarsia Formosa. For this purpose, a 6-link mechanism is designed for three positions of wings by synthesis using kinematic inversion, and dynamic force ....etc

ABSTRACT


MICRO AIR VEHICLES




Have you ever thought of a class of air vehicles which are less than 15 cms in size (most prominent linear dimension), can hover for two to three hours in air at a velocity of 20 to 30 mph at an altitude of 600 meters or even higher. This seminar will give you an idea of such vehicles called MAVâ„¢s (micro air vehicles). A dwell into the design and aerodynamics of such vehicles would be quit ....etc
