SpinLaunch engineers have been developing a new class of ultra-low-cost satellites for high-g environments. It can be hard to imagine a delicate satellite surviving a kinetic launch. Intuition suggests that they would need to be heavy, expensive, and have compromised performance. Yet through basic mechanical design, prototyping, and high-g testing, SpinLaunch has proven that standard materials and processes can be used to readily build satellites for kinetic launch that perform as well as their conventional counterparts.

The structures, mechanical assemblies, batteries, propulsion systems, and solar arrays we've developed and tested have no meaningful mass or cost increase. With SpinLaunch’s in-house experience and high-g testing capabilities, customers can take advantage of kinetic launch without compromise.

The High-G Environment

The centripetal high-g environment is unique and few testing environments exist. Leveraging the SpinLaunch 12-meter and 33-meter accelerators, which are capable of spinning hardware to 10,000g and up to five times a day, SpinLaunch engineers rapidly iterate through many design-analyze-build-test cycles to optimize satellite components for the centripetal environment.

This engineering process has been used to develop high-g reaction wheels for 20kg and 200kg-class satellites, deployable solar arrays and electric propulsion modules. Even unmodified smartphones, action cameras, and telescope lenses have survived without damage. In comparison to mechanical systems, electronics are surprisingly simple to ruggedize for kinetic launch. Because of the relatively low mass of resistors, capacitors, and electronic chips, many existing designs can be flown without any substantial modifications.

Mass Efficient Satellite Structures

SpinLaunch is engineering a variety of efficient satellite chassis, which require no more than a 10% increase in mass compared to those designed for the traditional launch environment. Satellite structures optimized for the high-g environment are readily analyzed with finite element modeling with predictions that closely match real-world testing, allowing for rapid iteration and development. The net result is a family of structural components that are ready-to-use with little to no impact to mass or cost. Our Space Systems team offers engineering support to customers developing SpinLaunch compatible satellite architectures.
