All Industries – Vibration, Acoustic and Thermal Insulation
Space
Attachment of boosters to the central body of the Ariane 5 rocket
Presentation
Booster attachments are intended to fix boosters to the central body of the rocket and dampen thrust oscillations without interfering with the launcher flight.
Advantages
The system combines the flexibility required to filter vibrations with resistance for the transmission of booster thrust. Rigidity is very low for movements of the order of 150 mm, leading to high system efficiency
Applications
Used on the Ariane 5 rocket since 1996.
Suspension for liquid helium tank
Reduces vibrations when the rocket lifts off.
Presentation
Metal-rubber part designed to absorb the variable load of the tank during the flight. Utilization time 600 seconds.
Advantages
Reduces stresses to all structures.
Applications
Suspension of variable load components.
Thermal insulation materials and equipment for satellite launchers and equipment
Presentation
Satellites, launchers, shuttles and space capsules, orbital stations and other space vehicles require high efficiency thermal protection operating in stress-laden environments.
In collaboration with its clients, Jehier designs insulating materials and equipment required for the thermal control of spacecraft.
Applications
Superinsulation of satellites, heat insulation of motors and cryogenic tanks, hot zones of launchers, flame arresters, and atmospheric re-entry protection systems are manufactured by Jehier.
