Experimental assessment of an active flap device

During the past thirty years, noticeable consideration has been devoted to the improvement of rotary-wing vehicles, with respect to noise, vibrations and performance. The main rotor of helicopters, and more precisely the blades themselves have been the subject of numerous optimization studies.

Active control of vibrations of a space truss using amplified piezoelectric actuators

The new piezo actuators manufactured by Cedrat Technologies have been developed for the positioning control of space optics but they are spreading widely in various engineering fields such as precise positioning, intelligent control of shapes and generation or control of vibrations. Their ability for the control or active damping of vibrations has been successfully demonstrated at the lab scale in space applications. In a first case, the piezo actuators were used for both for the control of launching vibrations and the positioning control in orbit of a telescope mirror. In a second set of space applications, these piezo actuators have been successfully integrated in a space truss using active tendons for control of micro vibrations, as publicly released at the Industry Space Days (ISD2001, Noordwijk, 9-10 Mai 2001) and as presented in this paper.

Actionneurs piezoélectriques pour positionnement rapide et précis

Several classes of low voltage piezo actuators have been developed by CEDRAT TECHNOLOGIES to cover precise positioning needs and / or fast. This paper discusses the ability of these actuators to cover these needs and illustrates this through various applications (mechanisms, shock absorbers, valves) in the fields of instrumentation, space, aeronautics and automotive.

3D ultrasonic imaging probes

Implementation of 3D capabilities on ultrasonic imaging systems tantalizingly proves the high interest for this diagnosing modality. However, to become a clinical tool, 3D ultrasound has to spend further technological efforts in acquisition performance and probe size to deliver on the fly, quality volumetric images as well as current functionalities.
