Key Applications for Rocket and Satellite Springs
Springs are extremely versatile components found within numerous propulsion and space vehicle mechanisms and systems, including actuated equipment within safety-critical systems. For example, extension springs are commonly used in mechanical component retention systems, such as downlock mechanisms on landing gear strut assemblies.
For example, large compression springs are integrated into satellite delivery mechanisms, rocket staging, and separation actuation systems. Aerospace-grade torsion springs are also used within satellite and antenna arrays to permit reliable communication assets in orbit. Springs are also found in rocket engines and propulsion systems, as ultra-high-performance custom springs, such as canted coil springs, are integrated into propulsion system components, such as engine valves that require tightly controlled dimensional tolerances as well as cryogenic sealing systems.
All components in these assemblies must operate reliably to ensure the safety of all occupants for every last mission. Every spring designed for space applications is carefully optimized and manufactured to the highest quality standards, ensuring reliable performance in microgravity, high loads and vibrations, and extreme temperature fluctuations encountered throughout the entire mission lifecycle.
Material Selection and Manufacturing Capabilities for Space Springs
Proper material specification is a critical factor in ensuring the long-term reliability of springs in aerospace applications. Century Spring’s team of in-house design and manufacturing experts knows which materials can best withstand the harsh conditions of vacuum, radiation fields, and large temperature gradients. Common spring materials for such ultra-high-performance, large-vibration frequency, and high-load applications include Inconel and Elgiloy. For springs that require a measure of corrosion resistance, 17-7 Stainless Steel (SST) is a suitable option, while titanium is an excellent spring material choice for weight optimization. All of which offer exceptional resistance to fatigue, corrosion, and mechanical and thermal stresses.
Many spring materials alloys can also be specified with optimized surface coatings and finishes to further enhance durability and performance.
Century Spring stocks many aerospace-grade materials, including many of the materials mentioned above, to support the rapid production of custom springs and allow for the delivery of custom components within two weeks of purchase order placement.
Century Spring utilizes advanced manufacturing and testing protocols specifically designed for aerospace-grade components. As required, springs undergo load testing, dimensional verification checks, and non-destructive evaluation (NDE) to confirm mechanical integrity and dimensional accuracy. These processes ensure that each unit meets the strict dimensional shape and tolerances required for deployment, actuation, or separation mechanisms in space systems.
Our dedicated engineering and quality assurance teams are trained to comply with the requirements of space vehicles, propulsion systems, and satellite components. Our expertise in materials science, precision forming, and aerospace compliance positions us to consistently deliver springs that perform flawlessly in both mission-critical and safety-critical applications.

FAQs About Space Springs
How do springs function in zero-gravity or vacuum environments?
All other environmental factors being equal, springs fabricated from high-quality materials and modern manufacturing methods perform as intended in both zero gravity and vacuum environments. This is because springs function by the elastic deformation of the coils, which store energy independently of gravitational forces or atmospheric pressure.
What materials perform best in high-radiation or temperature extremes?
Nickel-based alloys, such as Inconel®, are the highest performing material options for high-radiation and extreme temperature environments. Such super-alloys are specifically engineered to maintain strength even at extremely high temperatures. For example, nickel-based alloys such as Inconel® and Elgiloy® alloys are used in high-radiation fields within nuclear power applications where temperatures exceed 1000 °F.
However, Titanium alloys and 17-7PH stainless steel are also excellent, more economical options for less extreme space applications.
How are space-grade springs tested for durability and precision?
Space-grade springs are tested in certified testing laboratories using rigorous mechanical, thermal, and non-destructive testing methods to ensure they meet the reliability demands of launch and orbital equipment throughout the entire mission. For example, mechanical fatigue testing is commonly performed to determine the fatigue life of the spring by cycling a known load in a controlled manner until the spring fails. Mechanical shock and vibration testing is also commonly performed to ensure that springs can withstand the extremely high-frequency oscillating loads and large magnitude load impulses during liftoff and separation stages of the vehicle delivery platform. Thermal vacuum testing involves exposing the spring to the full temperature gradient in a vacuum chamber to determine how the spring will function when deployed in orbit.
Finally, in addition to rigorous testing campaigns, all space-grade springs adhere to strict aerospace-grade quality control standards, such as ISO 9001, to ensure that every spring and wire form product is interchangeable and fully traceable.
Can springs be customized for specific satellite or rocket components?
Yes, Century Spring’s team of spring design experts is available to partner with you in developing custom solutions for highly specialized satellite control and rocket components, designed from the ground up to fit your operational requirements.

What design factors must be considered for launch vibration and deployment reliability?
Designing springs for launch vibration and deployment reliability in aerospace and space systems requires a balance of mechanical resilience, precision, and environmental adaptability. A few key design factors that must be considered exclusively for launch vibrations include high-frequency cyclic loading, shock loading, and any applicable equipment isolation requirements. Key design factors to ensure the reliability of springs during deployment in space applications include precision force control requirements for deployable mechanisms and thermal/vacuum performance.
