Although there is certainly less vibration in a micro-gravity environment, applications such as the International Space Station still experience noise and vibration. Ventilation systems, research experiments, space vehicle dockings and even astronaut activities contribute to noise and vibration.
In addition, as NASA gears to send astronauts to Mars, sensitive equipment that will be used needs to be properly isolated from unwanted shock and vibration.
Shock Tech supplies a variety of vibration isolators, shock mounts and assemblies for applications including:
- Exoatmospheric Kill Vehicles (EKV)
- Low Earth Orbit Research Experiments
- Oxygen Regulators/Life Support Systems
- Auxiliary Power Units
- Payload Mounting Systems
- Guidance Systems
Shock Tech Mounting & Isolation Solutions
Unique design with customizable characteristics:
• Isoelastic and equal stiffness in all axes.
• Varying stiffness and damping ratio.
• Meets NASA’s outgassing requirements: TML ≤1.0% & CVCM ≤ 0.1%.
• Wrench flats incorporated in the isolator design for ease of assembly.
• Available with varying mounting threads; universal or metric.
• Adaptable to high installation torque values.
• No sealed air pockets by design.

Rapid Cycle Amine (RCA) System
Currently under development by NASA with UTC Aerospace Systems; the RCA technology is a new carbon dioxide (CO2) and humidity removal system that has been baselined for the Advanced Extravehicular Mobility Unit Portable Life Support System.
Shock Tech provides mid-frequency isolators capable of withstanding a 30g shock input.
NASA Space Launch System (SLS)
NASA’S SLS, is slated to launch astronauts in the Orion spacecraft beyond Earth’s orbit on missions to an asteroid and eventually to Mars. Shock Tech will provide mounting for the Auxiliary Power Unit (APU).

Aboard NASA’s Aura satellite, the HiRLDS (High Resolution Dynamics Limb Sounder) measures infrared radiation from ozone, water vapor, CFCs, methane and nitrogen compounds.
Shock Tech provided the mounting system (pictured left) for the HiRLDS instrument.
International Space Station
Shock Tech has provided mounting and isolation solutions for numerous low earth orbit research experiments aboard the ISS.
Thruster firings, dockings and equipment generate substantial amounts of vibration that can have negative impacts on sensitive instruments aboard.
Development and Prototype Systems
Shock Tech is committed to advancing research and development in the missile and launch vehicle industry through custom solutions and prototype mounting systems.
