Air, Space & Defence markets are looking for more and more Mechatronic Solutions for improving flight or observation performance.
These have to be light-weight, efficient and highly reliable. CEDRAT TECHNOLOGIES's mechatronic components and systems for Air, Space & Defence can be found in airplanes, helicopters, missiles, military vehicles, Micro aerial vehicles (MAV), satellites and nano satellites, spacecraft, Unmanned aerial vehicles (UAV), to address following functions & applications:
Many fast actuation functions in air, space and defence applications are performed with CEDRAT TECHNOLOGIES actuators, taking benefit of their high energy density, robustness and low power found in APA ®, LSPA, PPA and MICA.
These functions include: Actuation of flaps, fins, winglets in helicopters, missiles and UAVs ; Pulsed jets and synthetic jets in airplane ; Active Damping of vibrations for cameras, optic equipment, landing gears ; Sonic and ultrasonic Vibration generation for X-ray dust analyser & tribometers.
Fast & Fine positioning functions realized by CEDRAT TECHNOLOGIES (CTEC) mechanisms have become very mature for optical and optronic applications, including spacecraft applications. Strong heritage in space flight instruments such as interferometers, Lidar, magnetometers, telescopes, and cameras, has allowed CTEC to develop reliable and cost efficient mechanisms in the field of Free Space Optics (FSO), which is now becoming a major technical stake for giant constellations. Next generation mechanisms from CTEC for Spacecraft and Optronic applications includes Pointing Ahead Mechanisms (PAM), Fast Steering Mirrors (FSM) for Line of sight Stabilization (LOS) or large angle Raster Scanning, as well as XY Stages for in plane optical scanning using lenses and optical fibers. CTEC mechanisms features short response time with high precision, large frequency bandwidth, high force density, together with high mechanical strength for surviving vibrations and shocks loads during space launch, or embedded Optronics operational conditions. CTEC mechanism’s generic field of application is wide, with a high capability of customization and co-engineering with customers, which is especially appreciated. Many co-engineering references have been established with customers in the fields of Atomic Force Microscopes (AFM), Refocusing of Optics, Tuning of laser cavity in Meteosat, Shape control of antennas and mirrors, Proportional flow control in micro thrusters, pressure and flow regulators, pressure wave generators, Synthetic Jet Actuators (SJA) and Pulsed Jet Actuators (PJA), linear micro-compressors for advanced thermal machines to list a few…Additional functions are provided by CTEC for Clamping needs such as Latch actuators and hold-down and release mechanisms (HDRM), sometimes necessary for the maintaining or the liberating of a micro positioning mechanism, with high force density and controlled motion. From such a wide range of historical applications CTEC is now benefiting from a large actuator suite.
For the above-mentioned applications, CEDRAT TECHNOLOGIES often implement precise position sensors such as Strain Gauges or Eddy currents sensors in its mechanisms for achieving Compact Dynamic & Precise motion control. These sensors have been optimised for offering high reliability, low power, low weight and high precision.
CEDRAT TECHNOLOGIES is also used to develop sensors and detection systems for Air, Space & Defence applications. Customized sensors include contactless rotation speed or torque sensors for example for aircraft ABS or helicopter turbine control. Structural Health Monitoring (SHM) in aircraft using Lamb waves is an example of detection system where CEDRAT TECHNOLOGIES provides a useful suite of piezo transducers and electronics solutions.
For addressing these functions and applications, CEDRAT TECHNOLOGIES delivers innovative mechatronic components and functions following two approaches:
