ReMAP: Real-time Condition-based Maintenance for Adaptive Aircraft Maintenance Planning

September, 2018

H2020 ReMAP Project will contribute to reinforce the European leadership in aeronautics by developing an open-source solution for aircraft maintenance, the Integrated Fleet Health Management (IFHM) system. By replacing fixed-interval inspections with adaptive condition-based interventions, ReMAP will have an estimated benefit to the European aviation of more than 700 million Euros per year. This is due to a direct decrease in maintenance costs, reduced unscheduled aircraft maintenance events, and increased aircraft availability. In this project, Cedrat Technologies (CTEC) will be responsible for managing the technical activities of ReMAP WP3 which concerns the development of the selected sensor technologies for damage monitoring and will drive the realisation of CTEC share in ReMAP focusing on piezo solutions for SHM.

HPPA piezo actuator on-board the flying AEOLUS ALADIN Lidar

September, 2018

On 22/08/2018, ESA’s AEOLUS satellite was successfully launched into polar orbit on a Vega rocket. AEOLUS carries ALADIN, the first instrument measuring the wind from space ever built. ALADIN is a DOPPLER LIDAR using a Laser Transmitter (TXA) developed by GALILEO AVIONICA (presently LEONARDO).

In this interferometric application, the high power laser has both to emit frequency stable light and to be precisely tunable (for receiver calibration), which is contradictory.  To this end, a laser frequency control is performed by the dynamic tuning of the laser cavity (Master Oscillator) of the TXA Power Laser Head. To realise this tuning, CEDRAT TECHNOLOGIES (CTEC) has developed for GALILEO AVIONICA a Hollow Prestress Piezo Actuator (HPPA) which modify the cavity length by fine and fast moving the output coupler of the Master Oscillator.

Severe dynamic specifications were unusually required for this HPPA piezoactuator. The HPPA had to present a resonant frequency of about 30kHz to offer a bandwidth of 10kHz. Correlatively qualification required a very large number of cycles reaching 4.1010 cycles, which was passed establishing a new life time record. An additional lesson learnt was the need for Lot Acceptance Test (LAT) and Destructive Part Analysis (DPA) in order to secure and to comply with the quality process applied on the batch  of multilayer piezo ceramics from the Engineering to the Flight models. Thanks to LAT and DPA defined and applied by CTEC, any defects observed inside the batch samples of piezo ceramic parts with critical impact on the performances of the HPPA (dynamic, life time,etc...) have been unveiled. These LAT & DPA results were feedback to the partner supplier of the piezo ceramic batch in order to correct, to adjust and to improve accordingly its manufacturing process for making optimum quality parts. This LAT & DPA helped to strengthen the quality insurance on the critical part (piezo ceramic) and the partnership between CTEC, its supplier and client while solving any risk of project delay due to manufacturing quality issues on critical part like piezo ceramic.   

Since this event, ESA has entrusted the ECSS norms for the design and test of piezo actuators in space to CTEC. The experience gained by CTEC in ALADIN has been used to develop other HPPA actuators for SWARM mission (flying since 2013) as well as for the Beam Steering Actuator (BSA) of the ATLID Atmospheric Lidar for EARTHCARE satellite.  It could be useful also for other ESA future Meteorological missions using a LIDAR such as MERLIN.

New modular stepping piezo motors MSPA

September, 2018

MSPA modules ensure miniaturisation functions for fast micro positioning on unlimited strokes either linear or rotating: with typical sizes in the range cm3, these modules perform the tangential drive of a load by friction. The load driven by a MSPA can be either the mobile part of stage or a rotor. Their tangential driving speed can vary from 0 to 50mm/s. Their driving force can reach more than 1N. When power off, the load is locked at rest, with a holding force up to 10N. In dynamic, the MSPA modules perform controllable micro steps of 5 to 25µm by inertial effect driving the load in stick slick. Because of its inertia, the load can be driven at constant speed. In quasi-static, the MSPA offer a fine positioning of the load, better than 1 nm in linear or 10 pico rad in rotating. The MSPA allows the realisation of piezoelectric motors powerful and very reliable: the MSPA are based on the Amplified Piezoelectric Actuators APA® high reliability components benefiting of a large space heritage: The MSPA can work in vacuum and in a large range of temperatures from -270°C to 70°C. They resist to shocks and vibrations. They are cost effective because based on only one APA® needing only one electronic supply channel. The MSPA applications address the linear and rotating micro-motorisations for refocusing, goniometers, samples orientation, shutters, wheel filters, pointing mechanisms… The development of MSPA is supported by BPI France in the framework of Eurostars ELVISA project.

Magnetic fast steering mirrors M-FSM

September, 2018

CEDRAT TECHNOLOGIES (CTEC) piezo mechanisms and their associated electronics are widely used in Air, Space & Defence (ASD) applications. They can be found in optical instruments, cameras, telescopes and electro optic systems embedded on airplanes, helicopters, unmanned aerial vehicles (UAV), satellites, spacecrafts. Fast Steering Mirrors (FSM) are core products continuously developed by CTEC for optical pointing applications for Space and Optronics. During the last decade, best development efforts have been focused on piezoelectric mechanism technology, in order to achieve ultra-high frequency bandwidth control performance over small angle strokes (< 1°). New applications under maturation in Europe, such as laser optical communication, require much higher angle strokes compared to the existing state of the art, which cannot be easily achieved by piezoelectric technology. Therefore, CTEC is focusing on the development of a new family “Magnetic Fast Steering Mirror” (M-FSM) based on high angle stroke magnetic actuators (~ 4°).

New MICA300CM™ flexure bearing linear actuator

September, 2018

CEDRAT TECHNOLOGIES is revealing its new MICA300CM Flexure Bearing linear actuator (Moving Iron Controllable Actuator), with associated drive electronics, in order to provide very high reliability solutions to customers having demanding applications. The MICA linear actuators family has been specifically developed for ultra-long lifetime applications, allowing to achieve zero maintenance over several years of continuous operation. This performance is achieved thanks to both fixed coils and fixed magnets’ designs, having no moving electrical flying leads, and thanks to efficient contact free flexure bearing designs. The moving iron actuator designs proposed by CEDRAT TECHNOLOGIES reach the highest performances in the domain. The MICA feature high controllability, higher force levels, smaller compact volumes, and higher electrical efficiencies, compared to other classical magnetic actuators, such as classical voice coils. This high efficiency results in very low heat dissipation, together with easy and direct heat sinking by conduction on dedicated interfaces. Together with the MICA product family, the 1KVA CSA96 switching amplifier drive electronic has been developed. It features reactive power recovery, reaching an electrical efficiency higher than 90% and it is able to drive both single and multiple MICA configurations. Development of MICA actuators, and associated drive electronics, is supported by TOTAL, in the frame of ALICOP funding project.

The first of a number of products being developed within the MC-Suite project has been undergoing testing, with excellent results.

The single axis force feedback table is able to measure loadings up to 20kN, however at the same time the rigidity of the system remains high, with a calculated stiffness of 3.05kN/µm in the vertical direction. The table is rated IP67, and with a diameter of 100mm by 70mm high, and a weight of 3.1kg remains compact.

View the video to see the table in operation!

The use of an ECS sensor allows the cost of this table to be considerably lower than existing tables using alternative sensor systems, furthermore the ECS technology is easily scalable, enabling greater loading or more axis of measurement to be easily achieved.

Further products being developed within MC-Suite include a single axis force feedback tool holder equipped with wireless data transmission and an active proof mass damper.

MC-Suite is funded by the European Commission under the Horizon 2020 Programme GA n°. 680478".

CLIMA project - Damping linkage design collaborative project – Successful annual meeting

June 19th, 2017

Cedrat Technologies is member of CLIMA project, funded under the FUI 19, involving 10 French partners, with a duration of 3 years.

The work of the project focuses on mechanical junctions, which are the main source of depreciation in many cases. The project aims to develop innovative technological solutions (damping bearings, self-locking nuts, damping collages, instrumented fixings, pilot fasteners) as well as specific software tools for the identification and prediction of damping in these junctions. The innovations generated by the CLIMA project must make it possible to reduce the risks of over-dimensioning of structures, which result from ignorance of precise dynamic behaviour.

Cedrat Technologies hosted the half project meeting (To+18m) in its facilities in Meylan. It has been the opportunity for the partners to discover laboratory and production means and capabilities besides presenting advancements within the project and especially the Micro controller demonstrator, for embedded closed-loop piezo actuators, developed with partners.

Cedrat Technologies wants to thank its partners for this efficient and fruitful meeting.

A piezo Point Ahead Mechanism or a Fast Steering Mirror

June 19th, 2017

The Double Tip Tilt (DTT35XS) from CEDRAT TECHNOLOGIES (CTEC) is a piezo Tip Tilt Platform to move or to position a mirror along 2 axis of rotation. The purpose is to make either a Point Ahead Mechanism or a Fast Steering or a Beam steering Mirror. The first DTT35XS prototype was initially developed in 2003 for the CNES space project called PHARAO.

The DTT35XS off the shelves version is based on two pairs of APA35XS, Amplified Piezoelectric Actuators APA® displaying 35 µm of stroke each, arranged in cross configuration to allow an angular deflection of +/- 2 mrad around the X and Y axes. In order to achieve the two θx and θy angular deflections, each pair of APA35XS is electrically driven in push pull configuration and controlled in position by the standard CCBu20 controller box.

CTEC have been developing several customized versions of the DTT35XS together with CCBu20 for more than 10 years that are now widely used and embedded in Electro-Optic (EO) space and defence systems.

The features of the standard & custom designed versions of the DTT35XS provides the EO customers with a Compact, Dynamic and Precise solution to improve the performances of their embedded vision systems.

To name but a few applications are:

  • Micro-scanning, Dithering or Pixel shifting for image resolution enhancement of low cost detectors,
  • Optical image or line of sight (LOS) stabilization for anti shaking or anti blurring functions in order to obtain better image quality,
  • High precision Pointing ahead for free space optical (FSO) communication systems,
  • Fast steering mirror for Atmospheric disturbances compensation of astronomical imaging system (telescope) or high power laser beam system (DEW)

In the frame of ROXTAR, a MINALOGIC project dedicated to develop the next generation of XRay sensor for medical application, it has been spotted by our partner TRIXELL the interest to develop the capability of a blinded alignment between the imager and Xray emitter. The alignment function allows a better positioning of the imager relatively to emitter in order to:

  • Reduce the Xray dose exposure for any patient by avoiding multi shots to obtain one picture
  • Improving the quality of pictures

Cedrat Technologies (CTEC) designed and developed an accurate contactless magnetic long range (1.5 m) alignment function, based on magnetic technologies. This challenging technology where optical alignment is not allowed brings a positioning help to the medical operator, and hence achieve an alignment with a position resolution lower than 1mm and an angle resolution less than 0.1°.
A demonstrator has been developed integrating an user friendly Graphical User Interface, and shows the full capabilities of CTEC to specify and design from hardware to system level.

More information will be soon available.

Successful wake up of ESA Rosetta satellite and MIDAS instrument!

May 19th, 2014

A few weeks ago, ESA announced a successful wake up of Rosetta satellite and MIDAS instrument. ROSETTA satellite was launched on March 2004 from Kourou, French Guyana, using an Ariane-5 G+ launcher. The spacecraft includes about ten different instruments whose one so called MIDAS.  

The MIDAS instrument uses an XYZ piezo electric stage from CEDRAT TECHNOLOGIES in the scanning mechanism of its on-board Atomic Force Microscope (AFM). The function of this mechanism is to ensure the nano-resolution scanning motion of the AFM under a severe environment. Although operated under static conditions, the ability of CEDRAT TECHNOLOGIES actuators to withstand large vibrations thanks to their pre-stress allowed the mechanism to pass vibration tests.  

After 10 years CEDRAT TECHNOLOGIES mechanism is still working fine!
