ADR designs and manufactures linear and rotating electromechanical actuators that meet the specific needs of controlled positioning, repeatability of movement, power and load capacity.

ADR linear and rotating electromechanical actuators combine high efficiency with a small size and low weight.

ADR relies on this innovative technology to develop optimized solutions for embedded systems and servitude management: emergency actuators, secondary flight control actuators, etc.

ADR designs and manufactures a wide range of high-precision ball bearings that comply with the most demanding technical specifications and are EN9100 certified.

The materials, liquid or solid lubricants and manufacturing processes are qualified and field proven. The range of ADR's bearings is vast: from 1 to 330 mm and up to ABEC 9 (ISO 2). They guarantee high reliability and resistance in the most restrictive environments: vibration, thermal, climatic, speed, etc.

ADR ball bearings are present in various aeronautical and space equipment and instruments such as valves, pumps, actuators, turbochargers, and more.

ADR designs and manufactures preloaded duplex ball bearings.

ADR bearings guarantee the best compromise of stiffness and friction torque while optimizing the weight, dimensions and cost of the equipment. This specific design uses qualified materials and liquid or solid lubricants and is responsible for the excellent performance and repeatability of behavior of these bearings.

Assembly and final inspections in a clean room ensure a high level of cleanliness and spatial compatibility. ADR integrated bearings are in particular used in satellite mechanisms such as the deployment of solar panels or antennas (SADM), engine orientation, inertia wheels, filter wheels, etc.

For over fifteen years, ALSYMEX has designed and manufactured invar molds with specific deformation profiles used for manufacturing geostationary satellite antenna reflectors.

Based on theoretical data and using specific semi-finished equipment supplied by the client, ALSYMEX manufactures, machines and polishes reflectors with a diameter of up to 3 m within a maximum period of thirty days.

ALSYMEX designs and manufactures a range of effective safety device solutions for propulsion systems:

• Aeronautical non-return valves
• Subsea safety valves
• Tank lids

The experience acquired from over 50 years in manufacturing of tube fittings for nuclear applications with a very high level of safety and dependability is what makes ALYNOX able to offer competitive, alternative solutions for Aeronautics & Space applications.

The components manufactured by ALSYMEX, in stainless steel and/or nickel alloy (Inconel), using an innovative hydro-forming technology, have high-performance mechanical properties and enable substantial on-board weight savings.

By way of an example, ALSYMEX produces Inconel fittings installed on the fuel circuit of the A400 M's engines.

ALSYMEX also has a line of ABF three-piece machined fittings, which are removable and have metal-metal sealings (250 bar – 600 °C). Their design can be adapted to any of our clients' needs (SW, BW, threaded, etc.). 

ALSYMEX studies and designs cooling systems based on two-phase liquid loops. These upstream theoretical and experimental studies involving two-phase cooling issues have now enabled a global industrial solution to be offered for thermal management of new-generation high heat flow density power electronics (thermal flux).

Thermal transfer components line – DIPHASIK^®:

• Fully sealed miniature pump
• Condenser
• Dynamic evaporator
• Fluid (phase change)
• Fully sealed fluid connector

ALSYMEX designs and manufactures a line of flow control valves intended for propulsion subassemblies of satellites engines, with a thrust ranging from 1 to 500 N and either monopropellant or bipropellant.

With a robust and field-proven design, ALSYMEX valves are "Flight Proven" certified. They are primarily used in apogee engines of geostationary satellites (telecom) and in propulsion systems of small satellites in low orbit for altitude control.

Also used in custom space applications from off-the-shelf equipment, ALSYMEX valves are adapted to the most demanding requirements, especially those expressed in launch vehicle applications or scientific space missions.

PMB designs and manufactures customized ceramic-metal components and assemblies. The quality of its production relies on its historical, recognized expertise in the assembly of dissimilar materials by vacuum brazing.

Manufacturing processes cover preparation, machining, surface treatment, controlled atmosphere vacuum brazing and welding.

PMB manufactures ceramic-metal penetrations, kicker chambers, connectors subjected to severe environments and pyrotechnic igniters.
